Description

Bluetooth connection method and electronic equipment

Technical Field

The present application relates to the field of electronic technologies, and in particular, to a bluetooth connection method and an electronic device.

Background

Bluetooth is a radio technology that supports short-range communication between devices. With the development of science and technology, more and more electronic devices with bluetooth function appear in people's daily life. In a full-scene intelligent connection scene, one electronic device may be connected to multiple devices via bluetooth.

However, when the number of devices connected to the electronic device through bluetooth reaches a certain number, a plurality of devices may seize the bluetooth link of the electronic device, so that other devices may no longer perform data interaction with the electronic device through bluetooth.

Disclosure of Invention

The application provides a Bluetooth connection method and electronic equipment, which can solve the problem that when the number of the electronic equipment connected through Bluetooth reaches a certain number, other equipment cannot perform data interaction with the electronic equipment through Bluetooth. In order to achieve the purpose, the technical scheme is as follows:

in a first aspect, the present application provides a bluetooth connection method, including: firstly, a first electronic device receives a first Bluetooth connection request sent by a second electronic device, wherein the first connection request is used for requesting to establish a first Bluetooth connection, and the first Bluetooth connection comprises a Bluetooth physical link connection and a Bluetooth service link connection; then, when the number of first target devices is greater than a first threshold, the first electronic device executes a first operation, where the first operation includes converting the first bluetooth connection with a second target device in the first target devices into a second bluetooth connection and establishing the first bluetooth connection with the second electronic device, the first target device is a device that establishes the first bluetooth connection with the first electronic device, and the second bluetooth connection includes a bluetooth service link connection.

Compared with the prior art, when the number of the devices connected through the bluetooth physical link is larger than a certain number, the electronic device cannot provide an idle bluetooth physical link to establish a new bluetooth connection because the bluetooth physical link is occupied, and therefore the electronic device rejects a subsequently received bluetooth connection request and notifies a connection initiator of connection failure. In the bluetooth connection method provided by the present application, when the number of devices connected through the bluetooth physical link is greater than the first threshold, and after subsequently receiving a bluetooth connection request sent by the second electronic device, the first electronic device reserves a bluetooth service link of the second target device connected through the bluetooth physical link and disconnects the bluetooth physical link, thereby releasing the bluetooth physical link through which the first electronic device and the second electronic device can establish a bluetooth connection. The service of the second target device keeps the state synchronization, so that the problem that when the number of the devices connected through the Bluetooth of the electronic device reaches a certain number, other devices cannot perform data interaction with the electronic device through the Bluetooth is solved, and the user experience is improved.

In one possible implementation, the method may further include: when the number of connectable devices is less than a second threshold, the first electronic device performs the first operation.

In one possible implementation, the converting the first bluetooth connection with a second target device to a second bluetooth connection includes: determining the second target device from the first target device; and disconnecting the Bluetooth physical link connection with the second target device.

In another possible implementation manner, the converting the first bluetooth connection with the second target device to a second bluetooth connection includes: determining the second target device from the first target device; disconnecting the Bluetooth physical link with the second target device and reserving the Bluetooth physical link with the second target device.

Optionally, the second target device is a first target device with the longest idle duration in the first target device or a first target device with the lowest service priority in the first target device, and the idle duration is a duration between a time when bluetooth service interaction is performed with the first electronic device last time and a current time.

In one possible implementation, the determining the second target device from the first target device includes: determining a third target device from the first target device, wherein the third target device is a device supporting a second Bluetooth connection; and determining the second target equipment from the third target equipment, wherein the second target equipment is the third target equipment with the longest idle time length in the third target equipment or the third target equipment with the lowest service priority in the third target equipment, and the idle time length is the time length between the time of performing the bluetooth service interaction with the first electronic equipment last time and the current time.

In one possible implementation, after converting the first bluetooth connection with a second target device to a second bluetooth connection, the method further comprises: when a target service exists, sending a first indication to the second target device, where the target service is a bluetooth service related to the second target device, and the first indication is used to indicate the second target device to establish a bluetooth physical link connection with the first electronic device.

In another possible implementation, after converting the first bluetooth connection with a second target device to a second bluetooth connection, the method further includes: and when the target service exists, sending a second Bluetooth connection request to the second target equipment, wherein the second Bluetooth request is used for requesting to establish a Bluetooth physical link.

In one possible implementation manner, when the first number of target devices is greater than a first threshold, the first electronic device performs a first operation, including: when the number of the first target devices is larger than the first threshold and the idle time of the first target devices is not smaller than a third threshold, the first electronic device executes the first operation; when the number of the first target devices is greater than the first threshold value and the idle time of the first target devices is less than the third threshold value, the first electronic device sends a second indication to the second electronic device, the second indication is used for indicating the second electronic device to establish a first bluetooth connection with the first electronic device through a fourth target device, and the first target device comprises the fourth target device.

It can be understood that the number of bluetooth physical links of the first electronic device is limited and the first bluetooth connection with the first electronic device needs to be established by occupying the bluetooth physical link of the first electronic device, so that the first electronic device needs to determine whether there is a currently idle (unoccupied) bluetooth physical link for establishing the first bluetooth connection according to the relationship between the number of the first target devices and the first threshold size when receiving the first connection request.

And under the condition that no idle Bluetooth physical link exists (namely the number of the first target devices is greater than a first threshold), the second target device is enabled to establish the first Bluetooth connection with the first electronic device by indicating the second target device to connect a fourth target device which has already established the first Bluetooth connection with the first electronic device, and the fourth target device is used as a relay agent. Therefore, the second electronic device and the fourth target device share one Bluetooth physical link to be connected with the first electronic device through the first Bluetooth, an additional Bluetooth physical link is not needed, a plurality of devices can be connected with the first electronic device through the Bluetooth through one Bluetooth physical link, the problem that when the number of the devices connected with the electronic device through the Bluetooth reaches a certain number, other devices cannot perform data interaction with the electronic device through the Bluetooth is solved, and user experience is improved.

In the presence of an idle bluetooth physical link (i.e., the number of first target devices is not greater than the first threshold), the first electronic device establishes a first bluetooth connection with the second electronic device over the idle bluetooth physical link.

In one possible implementation, the method further includes: and when the number of the first target devices is greater than the first threshold value and the idle time of the first target devices is less than the third threshold value, the first electronic device sends a third indication to the fourth target device, wherein the third indication is used for indicating the fourth target device to establish a first Bluetooth connection with the second electronic device.

It can be understood that, when the first electronic device has an available bluetooth physical link, switching the connection mode between the second electronic device and the first electronic device from relay proxy connection to direct connection may reduce communication delay between the first electronic device and the second electronic device, and improve communication speed between the first electronic device and the second electronic device, thereby further improving user experience.

In one possible implementation, the method further includes: and when the current electric quantity of the fourth target equipment is smaller than a fifth threshold value, disconnecting the first Bluetooth connection with the fourth target equipment and indicating the second electronic equipment to send a first Bluetooth connection request to the first electronic equipment.

It can be understood that, when the fourth target device is insufficient in power, the first electronic device indicates that the second electronic device is not connected with the first electronic device through the fourth target device, but directly connected with the first electronic device, thereby avoiding that the shutdown due to insufficient power of the fourth target device can cause the disconnection between the second electronic device and the first electronic device, which are connected through the first bluetooth established between the fourth target device and the first electronic device, and the bluetooth connection between the first electronic device and the second electronic device is interrupted, and further improving the user experience.

In one possible implementation, after disconnecting the first bluetooth connection with the fourth target device, the method further includes: and when the current electric quantity of the fourth target equipment is larger than a fifth threshold value, disconnecting the first Bluetooth connection with the second electronic equipment and indicating the fourth target equipment to send a first Bluetooth connection request to the first electronic equipment.

Indicator 192 may be an indicator light that may be used to indicate a state of charge, a change in charge, or a message, missed call, notification, etc. The SIM card interface 195 is used to connect a SIM card.

The software system of the electronic device 100 may employ a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the present application takes an Android system with a layered architecture as an example, and exemplarily illustrates a software structure of the electronic device 100.

Fig. 2 is a block diagram of a software structure of the electronic device 100 according to the embodiment of the present application. The layered architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into four layers, an application layer, an application framework layer, an Android runtime (Android runtime) and system library, and a kernel layer from top to bottom.

The application layer may include a series of application packages. As shown in FIG. 2, the application packages may include camera, photo album, music, settings, etc. applications.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions. As shown in FIG. 2, the application framework layers may include a window manager, content provider, view system, resource manager, notification manager, and the like.

The window manager is used for managing window programs. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

Content providers are used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

The view system includes visual controls such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and the like.

The notification manager enables the application to display notification information in the status bar, which may be used to convey notification type messages, and the notification information displayed in the status bar may disappear automatically after a short dwell, such as a message alert to notify the user that the download is complete. The notification manager may also be a notification that appears in the form of a chart or scroll bar text at the top status bar of the system, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, to prompt a text message in the status bar, or the notification manager may also sound a prompt such as a vibration of the electronic device, flashing of an indicator light, etc.

The Android runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system. The core library comprises two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The application layer and the application framework layer run in a virtual machine. And executing java files of the application program layer and the application program framework layer into a binary file by the virtual machine. The virtual machine is used for performing the functions of object life cycle management, stack management, thread management, safety and exception management, garbage collection and the like.

The system library may include a plurality of functional modules. For example: surface managers (surface managers), media libraries (media libraries), three-dimensional graphics processing libraries (e.g., openGL ES), 2D graphics engines (e.g., SGL), and the like.

The surface manager is used to manage the display subsystem and provide fusion of 2D and 3D layers for multiple applications.

The media library supports a variety of commonly used audio, video format playback and recording, and still image files, among others. The media library may support a variety of audio-video encoding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like. The 2D graphics engine is a drawing engine for 2D drawing.

For convenience of understanding, the following embodiments of the present application will describe a photographing process of an electronic device by taking the electronic device having the structure shown in fig. 1 and 2 as an example.

The technical solutions in the following embodiments may be implemented in the electronic device 100 having the hardware architecture and the software architecture described above.

When a user uses the mobile phone, the user can often connect other devices through the Bluetooth of the mobile phone. If the mobile phone is connected with the tablet personal computer for data transmission, the mobile phone remotely controls the intelligent household appliance through the Bluetooth, and the mobile phone is connected with the Bluetooth sound box through the Bluetooth to play music and the like. However, when the number of devices connected through bluetooth of the mobile phone reaches a certain number, multiple devices occupy the bluetooth link of the mobile phone, so that other devices cannot perform data interaction with the mobile phone through bluetooth. If the number of connected mobile phones through Bluetooth reaches 7, when a user operates other equipment to set up the mobile phone through Bluetooth, the screen of the other equipment displays text prompts that the equipment cannot be connected, cannot be connected or fails to be connected, or the mobile phone displays a non-connectable state in a Bluetooth list of the other equipment. Therefore, the embodiment of the application provides a bluetooth connection method, which can solve the problem that when the number of devices connected by the electronic device through bluetooth reaches a certain number, other devices cannot perform data interaction with the electronic device through bluetooth any more.

The following describes in detail a bluetooth connection method provided in an embodiment of the present application with reference to the accompanying drawings, as shown in fig. 3, the bluetooth connection method provided in the embodiment of the present application includes:

s301, the first electronic device receives a first Bluetooth request sent by the second electronic device.

Wherein the first connection request is for requesting establishment of a first bluetooth connection. The first bluetooth connection includes a bluetooth physical link connection and a bluetooth traffic link connection.

Illustratively, a user wants to listen to music played by a mobile phone (a first electronic device) through a bluetooth headset (a second electronic device), and the user sends a first bluetooth request to the mobile phone by operating the bluetooth headset, and accordingly the mobile phone receives the first bluetooth request sent by the bluetooth headset.

Optionally, the first connection request may include a first sub-connection request and a second sub-connection request. The first sub-connection request is used for requesting to establish Bluetooth physical link connection, and the second sub-connection request is used for requesting to establish Bluetooth service link connection. For example, the first electronic device may receive the first sub-connection request sent by the second electronic device first, and then receive the second sub-connection request sent by the second electronic device.

S302, the first electronic device determines whether the number of the first target devices is greater than a first threshold? If yes, executing S303; if not, go to step S304.

The first target device is a device which establishes a first Bluetooth connection with the first electronic device.

Alternatively, the first threshold may be 6.

It should be noted that, the number of bluetooth physical links of the first electronic device is limited, and the first bluetooth connection established with the first electronic device needs to occupy the bluetooth physical link of the first electronic device, so that the first electronic device needs to determine whether there is an idle (unoccupied) bluetooth physical link for establishing the first bluetooth connection according to the relationship between the number of the first target devices and the first threshold when receiving the first connection request.

In the absence of an idle bluetooth physical link (i.e., the number of first target devices is greater than the first threshold), a bluetooth physical link is released for the first electronic device to establish the first bluetooth connection with the second electronic device by converting the first bluetooth connection with the second target device in the first target devices into the second bluetooth connection.

Exemplarily, the first electronic device may determine whether the number of the first target devices is greater than 6 by the protocol stack? If yes, executing S303; if not, go to step S304. That is, the first electronic device performs S303 when the first target device number is 0, 1, 2, 3, 4, 5, 6, and performs S304 when the first target device number is the remaining number.

In a possible implementation manner, the first device may also determine whether the number of connectable devices is smaller than the second threshold, if so, perform S303, and if not, perform S304.

Exemplarily, the first electronic device may determine whether the number of connectable devices is less than 1 by the protocol stack? If yes, executing S303; if not, go to step S304. That is, the first electronic device performs S303 when the number of connectable devices is 0, and performs S304 when the number of connectable devices is not 0.

In another possible implementation manner, the first electronic device may determine whether the number of currently available channels (i.e., the number of currently available physical channels or the number of currently idle channels) is 0? If so, go to step S303, otherwise, go to step S304.

In yet another possible implementation manner, the first electronic device may also determine that the number of currently occupied channels is greater than the fourth threshold? If so, go to step S303, otherwise, go to step S304. Wherein the fourth threshold may be 6.

S303, the first electronic device converts the first Bluetooth connection between the first electronic device and the second target device into a second Bluetooth connection.

Wherein the first target device comprises a second target device and the second bluetooth connection comprises a bluetooth traffic link connection.

Illustratively, the first electronic device may transmit a Bluetooth Low Energy (BLE) broadcast packet to the second target device instructing the second target device to convert the current first bluetooth connection to the second bluetooth connection.

Optionally, after the first electronic device and the second target device establish the second bluetooth connection, the first electronic device and the second target device may broadcast the synchronization status and the message through Ble.

In one possible implementation, converting the first bluetooth connection with the second target device to the second bluetooth connection may include: firstly, determining a second target device from first target devices; the bluetooth physical link connection with the second target device is then broken. Wherein, the second target device may be the first target device with the longest idle duration (i.e. idle time or traffic idle time) in the first target devices or the first target device with the lowest traffic priority in the first target devices, and the idle duration is a duration between the time when the first electronic device last performs bluetooth service interaction and the current time (e.g. the time 14 when the first electronic device last performs bluetooth service interaction is 50.

In another possible implementation manner, converting the first bluetooth connection with the second target device to the second bluetooth connection may include: firstly, determining a second target device from first target devices; the bluetooth physical link connection with the second target device is then broken and the bluetooth traffic link connection with the second target device is reserved.

It should be noted that, a specific method for the first electronic device to determine the second target device from the first target device may be processed by any method that can occur to those skilled in the art, and this is not limited in this embodiment of the present application.

For example, the first electronic device may determine, as the second target device, the first target device having the longest idle duration (i.e., idle time or business idle time) among the first target devices. The idle duration is a duration between the time of last bluetooth service interaction with the first electronic device and the current time (if the first target device and the first electronic device last bluetooth service (excluding the keep-alive service) interact at time 14, 00, the current time is 14.

For another example, the first electronic device may determine a first target device with the lowest priority of traffic among the first target devices as the second target device.

For another example, the first electronic device may determine a score of the first target device according to various parameters of the first target device (such as a connection number, a connection duration, a service priority, and the like), and then determine a first target device with a lowest score in the first target device as the second target device.

For example, the first electronic device may obtain the priority queue list shown in table 1 in the order from small to large of the idle duration of the first target device, then determine the first target device (i.e., device 7) with the largest idle duration in the priority queue list as the second target device, and then disconnect the bluetooth physical link connection with the device 7.

TABLE 1

Device	Idle time duration
		Device 1	00：00：30
Device 2	00：00：50
		Device 3	00：01：00
Device 4	00：01：10
		Device 5	00：03：00
Device 6	00：05：00
		Device 7	00：12：00

In one possible implementation, determining the second target device from the first target devices may include: determining a third target device from the first target device, wherein the third target device is a device supporting second Bluetooth connection; a second target device is determined from the third target devices. The second target device may be a third target device with the longest idle time of the third target device or a third target device with the lowest service priority of the third target devices.

It should be noted that, a specific method for the first electronic device to determine the third target device from the first target device may be processed by any method that can occur to those skilled in the art, and this is not specifically limited in this embodiment of the present application.

For example, the first electronic device may determine whether the first target device supports the second bluetooth connection based on a model, a brand, etc. of the first target device.

For another example, the first electronic device may send test signaling to the first target device to test whether the device supports the second bluetooth connection to determine whether the first target device supports the second bluetooth connection.

Compared with the prior art, when the number of the devices connected through the bluetooth physical link is larger than a certain number, the electronic device cannot provide an idle bluetooth physical link to establish a new bluetooth connection because the bluetooth physical link is occupied, and therefore the electronic device can reject a subsequently received bluetooth connection request and notify a connection initiator of connection failure. In the bluetooth connection method provided in this embodiment of the present application, when the number of devices connected through the bluetooth physical link is greater than the first threshold, and after subsequently receiving a bluetooth connection request sent by the second electronic device, the first electronic device reserves the bluetooth service link of the second target device connected through the bluetooth physical link and disconnects the bluetooth physical link, thereby releasing the bluetooth physical link through which the first electronic device and the second electronic device can establish bluetooth connection. The service of the second target device keeps the state synchronization, so that the problem that when the number of the devices connected through the Bluetooth of the electronic device reaches a certain number, other devices cannot perform data interaction with the electronic device through the Bluetooth is solved, and the user experience is improved.

S304, the first electronic device and the second electronic device establish a first Bluetooth connection.

In a possible implementation manner, if the target service exists, the first electronic device sends a first indication to the second target device. The target service is a Bluetooth service related to a second target device, and the first indication is used for indicating the second target device to establish Bluetooth physical link connection with the first electronic device.

In another possible implementation manner, if the target service exists, the first electronic device may also send a second bluetooth connection request to the second target device. Wherein the second bluetooth request is for requesting establishment of a bluetooth physical link.

As shown in fig. 4 (a), the first bluetooth connection includes a bluetooth physical link connection and a bluetooth traffic link connection. The upper layer service of the device can exchange service data flow with the Bluetooth physical link port of the device through a Bluetooth service link, and the Bluetooth physical link port of the device can exchange service data flow with the Bluetooth physical link port of the opposite device through the Bluetooth physical link. As shown in fig. 4 (b), in the case of disconnecting the bluetooth physical link connection between the device 1 and the device 2 and reserving the bluetooth service link connection, since the bluetooth service link connection is reserved, the upper layer service of the device 1 or the device 2 may still exchange service data streams to the bluetooth physical link port of the device through the bluetooth service link. Therefore, after the first electronic device converts the first bluetooth connection with the second target device into the second bluetooth connection, the upper layer service of the first electronic device may still interact with the target service (i.e. the service data stream of the bluetooth service related to the second target device) through the bluetooth service link and the bluetooth physical link port of the first electronic device, and the first electronic device may determine whether the target service exists through the bluetooth physical link port of the first electronic device, and if the target service exists, the bluetooth physical link needs to be established to transmit the data stream of the target service. Therefore, in the presence of the target service, the first electronic device sends a first indication to the second target device, the first indication indicating that the second target device establishes a bluetooth physical link connection with the first electronic device, and indicates that the second target device sends a first bluetooth request to the first electronic device to establish a first bluetooth connection between the first electronic device and the second target device. Of course, in the presence of the target service, the first electronic device may also directly send the first bluetooth request to the second target device to establish the first bluetooth connection between the first electronic device and the second target device.

It should be noted that, a specific method for the first electronic device to send the first instruction to the second target device may be processed by any method that can occur to those skilled in the art, and this is not particularly limited in this embodiment of the application.

For example, in the presence of the target service, the first electronic device may send, to the second target device through Ble broadcast, a first indication indicating that the second target device establishes a bluetooth physical link connection with the first electronic device, and instruct the second target device to send a first bluetooth request to the first electronic device to establish a first bluetooth connection between the first electronic device and the second target device.

It can be understood that the second target device may also determine whether the target service exists through a bluetooth physical link port of the second target device, and in a case that the target service exists, send a second indication for indicating that the first electronic device establishes a bluetooth physical link connection with the second target device to the first electronic device, and indicate that the first electronic device sends a first bluetooth request to the first electronic device to establish a first bluetooth connection between the first electronic device and the second target device, or in a case that the target service exists, the second target device may also directly send the first bluetooth request to the first electronic device to establish the first bluetooth connection between the first electronic device and the second target device.

When a user uses the mobile phone, the user can often connect other devices through the Bluetooth of the mobile phone. However, when the number of devices connected through bluetooth of the mobile phone reaches a certain number, multiple devices occupy the bluetooth link of the mobile phone, so that other devices cannot perform data interaction with the mobile phone through bluetooth. If the number of connected mobile phones through Bluetooth reaches 7, when a user operates other equipment to set up the mobile phone through Bluetooth, the screen of the other equipment displays text prompts that the equipment cannot be connected, cannot be connected or fails to be connected, or the mobile phone displays a non-connectable state in a Bluetooth list of the other equipment. Therefore, another bluetooth connection method is provided in the embodiments of the present application, which can solve the problem that when the number of devices connected by the electronic device through bluetooth reaches a certain number, other devices cannot perform data interaction with the electronic device through bluetooth any more.

Referring to the drawings, another bluetooth connection method provided in the embodiment of the present application is described in detail below, and as shown in fig. 5, the another bluetooth connection method provided in the embodiment of the present application includes:

s501, the first electronic device receives a first Bluetooth request sent by the second electronic device.

Illustratively, the user wants to connect with the bluetooth of the air conditioner through the bluetooth of the mobile phone (second electronic device) to adjust the temperature of the air conditioner, and then the user sends a first bluetooth request to the air conditioner by operating the mobile phone, and accordingly the air conditioner receives the sent first bluetooth request.

S502, the first electronic device determines whether the number of the first target devices is greater than a first threshold? If yes, go to S503; if not, go to S504.

The first target device is a device which establishes a first Bluetooth connection with a first electronic device.

Alternatively, the first threshold may be 6.

It should be noted that, the number of bluetooth physical links of the first electronic device is limited, and the first bluetooth connection established with the first electronic device needs to occupy the bluetooth physical link of the first electronic device, so that when receiving the first connection request, the first electronic device needs to determine whether there is an idle (unoccupied) bluetooth physical link for establishing the first bluetooth connection according to the relationship between the number of the first target devices and the first threshold.

Exemplarily, the first electronic device may determine whether the number of the first target devices is greater than 6 by the protocol stack? If yes, go to S503; if not, go to S504. That is, the first electronic device performs S503 when the first target device number is 0, 1, 2, 3, 4, 5, 6, and performs S504 when the first target device number is the remaining number.

In a possible implementation manner, the first device may also determine whether the number of connectable devices is smaller than the second threshold, if so, perform S503, and if not, perform S504.

Exemplarily, the first electronic device may determine whether the number of connectable devices is less than 1 by the protocol stack? If yes, go to S503; if not, go to S504. That is, the first electronic device performs S503 when the number of connectable devices is 0, and performs S504 when the number of connectable devices is not 0.

In one possible implementation manner, the first electronic device may determine whether the number of currently available channels (i.e., the number of currently available physical channels or the number of currently idle channels) is 0? If yes, go to S503, otherwise go to S50.

In another possible implementation manner, the first electronic device may also determine that the number of currently occupied channels is greater than the fourth threshold? If yes, go to S503, otherwise go to S504. Wherein the fourth threshold may be 6.

S503, the first electronic device sends a second instruction to the second electronic device to indicate the second electronic device to establish the first Bluetooth connection with the first electronic device through a fourth target device in the first target device.

In one possible implementation, the sending, by the first electronic device, the second indication to the second electronic device may include: the first electronic device determines a fourth target device from the first target devices, and then sends a second instruction to the second electronic device.

It should be noted that, a specific method for the first electronic device to determine the fourth target device from the first target device may be processed by any method that can occur to those skilled in the art, and this is not specifically limited in this embodiment of the present application.

For example, the first electronic device may first acquire the number of connected devices (the number of connected devices through bluetooth) of each first target device, and then determine the device with the smallest number of connected devices in the first target devices as the fourth target device.

For example, the first electronic device may obtain the number of connected devices of each first target device by sending a obtaining instruction to each first target device, then obtain the first target device information table shown in table 2 in the order from small to large of the number of connected devices of the first target device, and then determine the first target device (i.e., device 4) with the number of connected devices in table 2 as the fourth target device. Of course, the first electronic device may also determine any first target device with the number of connected devices smaller than the first threshold as the fourth target device.

TABLE 2

Equipment (MAC)	Channel identifier	Service (UUID)	Number of connected devices
				Device 4	A_B	Service 1	0
Device 2	DLC	Service (UUID)	2
				Device 1	DLC	Service (UUID)	3
Device 3	DLC	Service (UUID)	3
				Device 5	DLC	Service (UUID)	4
Device 6	DLC	Service (UUID)	5
				Device 7	DLC	Service (UUID)	6

Alternatively, the acquisition instruction for acquiring the number of connected devices may be a hiecho instruction. Table 3 shows the format of the hi ech o instruction, and as shown in Table 3, the command id field of the hi ech instruction can be used to add a definition instruction type, and the payload field of the hi ech instruction can be used to deposit data.

In a possible implementation manner, the first electronic device may also send a third indication to the fourth target device to instruct the fourth target device to establish the first bluetooth connection with the second electronic device as a relay agent.

Compared with the prior art, when the number of the devices connected through the bluetooth physical link is larger than a certain number, the electronic device cannot provide an idle bluetooth physical link to establish a new bluetooth connection because the bluetooth physical link is occupied, and therefore the electronic device can reject a subsequently received bluetooth connection request and notify a connection initiator of connection failure. In the bluetooth connection method provided in this embodiment of the present application, when the number of devices connected through the bluetooth physical link is greater than the first threshold, and after subsequently receiving a bluetooth connection request sent by the second electronic device, the first electronic device may establish the first bluetooth connection with the first electronic device by instructing the second target device to connect a fourth target device that has already established the first bluetooth connection with the first electronic device, and using the fourth target device as a relay agent. Therefore, the second electronic device and the fourth target device share one Bluetooth physical link to be connected with the first electronic device through the first Bluetooth, an additional Bluetooth physical link is not needed, a plurality of devices can be connected with the first electronic device through the Bluetooth through one Bluetooth physical link, the problem that when the number of the devices connected with the electronic device through the Bluetooth reaches a certain number, other devices cannot perform data interaction with the electronic device through the Bluetooth is solved, and user experience is improved.

It should be noted that the bluetooth protocol supports different service interactions through different DLC on the same bluetooth physical link, so that the second electronic device and the fourth target device can perform service interactions with the first electronic device through different DLC using the same bluetooth physical link.

For example, if a first electronic device sends a service data stream to a second electronic device, the first electronic device may obtain information of connected devices of each first target device, then obtain a connected device information table as shown in table 4, then determine that a DLC used by the second electronic device is B _4 according to the connected device information table, then send a service data stream with the DLC being B _4 to a fourth target device, and after receiving the service data stream, the fourth target device determines, according to the DLC of the service data stream or the MAC of the service data stream and the DLC lookup table 4, that the DLC of the data stream is not a _ B used for interaction between the first electronic device and the fourth target device, but is B _4 used by the first electronic device and the second electronic device, and then transmit the data stream to the second electronic device through a bluetooth physical link between the fourth target device and the second electronic device.

TABLE 4

It can be understood that, after receiving the service data flow sent by the fourth target device, the first electronic device may also determine the sender of the service data flow through the DLC of the service data flow or the MAC and DLC look-up table 4 of the service data flow.

When a user uses the mobile phone, the user can often connect other devices through the Bluetooth of the mobile phone. However, when the number of devices connected through bluetooth of the mobile phone reaches a certain number, multiple devices occupy the bluetooth link of the mobile phone, so that other devices cannot perform data interaction with the mobile phone through bluetooth. If the number of connected mobile phones through Bluetooth reaches 7, when a user operates other equipment to set up the mobile phone through Bluetooth, the screen of the other equipment displays text prompts that the mobile phone cannot be connected, cannot be connected with the equipment or fails to connect, or the mobile phone displays a non-connectable state in the Bluetooth list of the other equipment. Therefore, another bluetooth connection method is provided in the embodiments of the present application, which can solve the problem that when the number of devices connected by the electronic device through bluetooth reaches a certain number, other devices cannot perform data interaction with the electronic device through bluetooth any more.

Referring to the drawings, a detailed description is given below of another bluetooth connection method provided in the embodiment of the present application, and as shown in fig. 6, the another bluetooth connection method provided in the embodiment of the present application includes:

s601, the first electronic device receives a first Bluetooth request sent by the second electronic device.

S602, the first electronic device determines whether the number of the first target devices is greater than a first threshold? If yes, executing S603; if not, go to S605.

S603, the first electronic device determines whether the idle durations of the first target device are all smaller than a third threshold, if so, then S606 is executed, and if not, then S604 is executed.

It should be noted that, whether the service interaction between the first target device and the first electronic device is frequent may be determined according to a relationship between the idle time of the first target device and the size of the third threshold. When the idle time of each first target device is less than the third threshold, it means that each first target device and the first electronic device frequently perform service interaction, and if S604 is executed to convert the first bluetooth connection of a certain first target device into the second bluetooth connection, the service interaction between the first target device and the first electronic device is affected, and S606 is executed to select a certain first target device as a relay agent, i.e., the first bluetooth connection between the first electronic device and the second electronic device can be established without affecting the service interaction between the first target device and the first electronic device.

When the idle durations of the first target devices are not all smaller than the third threshold, it is indicated that there is a first target device in the first target device that has business interaction with the first electronic device that is not frequent, the first bluetooth connection of the first target device may be converted into a second bluetooth connection conversion by executing S604, so as to release the bluetooth physical connection occupied by the first target device for the first bluetooth connection between the first electronic device and the second electronic device.

It may be understood that, in the case that whether the number of the first target devices is greater than the first threshold, the first electronic device may also determine to execute S604 or S606 by using other determination conditions, which is not limited in this embodiment of the present invention.

For example, the first electronic device may determine whether to perform S604 or 606 according to the priority of the second electronic device. When the priority of the second electronic device is high (i.e., greater than the priority threshold), the second electronic device establishes the first bluetooth connection with the first electronic device through the separate bluetooth physical link by performing S604. When the priority of the second electronic device is low (i.e., less than the priority threshold), the second electronic device and the fourth target device share the bluetooth physical link to establish the first bluetooth connection with the first electronic device by performing S606.

For another example, the first electronic device may score the second electronic device according to information (e.g., device type, connection times, service type, service priority, etc.) of the second electronic device, and when the obtained score is higher than the score threshold, the second electronic device may establish the first bluetooth connection with the first electronic device through a separate bluetooth physical link by performing S604. When the obtained score is lower than the score threshold, the second electronic device and the fourth target device share the bluetooth physical link to establish the first bluetooth connection with the first electronic device by executing S606.

S604, the first electronic device converts the first Bluetooth connection between the first electronic device and a second target device in the first target device into a second Bluetooth connection.

S605, the first electronic device and the second electronic device establish a first Bluetooth connection.

S606, the first electronic device sends a second instruction to the second electronic device to indicate the second electronic device to establish the first Bluetooth connection with the first electronic device through a fourth target device in the first target device.

In a possible implementation manner, after the second electronic device establishes the first bluetooth connection with the first electronic device through a fourth target device in the first target device, the first electronic device may further send, to the second electronic device, a fourth indication to indicate that the second electronic device is disconnected from the fourth target device and send the first bluetooth connection request to the first electronic device, when the number of connected devices is smaller than a first threshold or the number of connectable devices is larger than a second threshold, and the like.

In another possible implementation manner, after the second electronic device establishes the first bluetooth connection with the first electronic device through a fourth target device in the first target device, the first electronic device may further disconnect the first bluetooth connection with the fourth target device and instruct the second electronic device to establish the first bluetooth connection with the first electronic device or instruct the second electronic device to send a first bluetooth connection request to the first electronic device under the condition that the current electric quantity of the fourth target device is smaller than a fifth threshold.

In yet another possible implementation manner, after the fourth target device disconnects the first bluetooth connection from the first electronic device because the current power is less than the fifth threshold, the fourth target device charges, and when the current power of the fourth target device is greater than the fifth threshold, the first electronic device may disconnect the first bluetooth connection from the second electronic device and instruct the fourth target device to establish the first bluetooth connection with the first electronic device or instruct the fourth target device to send the first bluetooth connection request to the first electronic device, and then send the second instruction to the second electronic device to instruct the second electronic device to establish the first bluetooth connection with the first electronic device through the fourth target device in the first target device.
