Description

Method and device for device information interaction between terminals

Technical Field

The present invention relates to the field of terminals, and in particular, to a method and device for device information interaction between terminals.

Background

At present, data mass sending can be realized between terminals by establishing a local area network. There are a variety of applications for implementing mass data transmission between mobile terminals.

These applications generally have a function of establishing a Wi-Fi (Wireless Fidelity) connection group through a Wi-Fi hotspot and a Wi-Fi direct connection mode, and a terminal may establish a local area network as shown in fig. 1 by joining the same Wi-Fi connection group. After the group is established, the terminal establishing the group can acquire the device information of the other terminals in the group, then establish a TCP (transmission Control Protocol) connection with the other terminals in the group, and send the device information of the terminal in the group to the terminal in the group through the TCP connection.

After acquiring the device information of other devices in the group, the terminals in the group can establish connection to the terminals in the group to initiate data transmission, so that one-to-many file sharing, namely data mass sending, is realized.

However, during the process of establishing TCP connection between the terminal of the group and other devices in the group, the connection is not established or is accidentally disconnected.

In summary, the existing method for acquiring the device information of the terminals in the group by the members in the Wi-Fi group through the TCP method has poor stability.

In the description of the present invention, the term "plurality" means two or more unless otherwise specified.

At present, one-to-one file sharing can be realized between terminals through technologies such as Bluetooth, and for a scheme of one-to-many file sharing between multiple terminals, a Wi-Fi connection group can be established through a Wi-Fi direct connection mode and a Wi-Fi hotspot connection mode, that is, after a terminal added into the same Wi-Fi connection group acquires device information of other terminals in the group, a connection can be established with the other terminals according to the acquired device information, so that data group sending is realized.

At present, terminals in a Wi-Fi connection group established in a Wi-Fi direct connection mode or a Wi-Fi hotspot connection mode interact with device information in a TCP mode, however, as is well known, the TCP mode is unstable in the stages of device searching, connection establishment in the early stage and the like, the device scanning and connection establishment speeds are slow, and the situations of no searching, accidental disconnection and the like often occur, so that bad experience is brought to users.

Further, for a Wi-Fi connection group (Wi-Fi hotspot group for short) established by a Wi-Fi hotspot connection mode, the terminal needs to join the Wi-Fi hotspot group, and may need to manually input the Wi-Fi hotspot password for device verification.

In the embodiment of the invention, the first terminal and the second terminal can be connected with each other through Bluetooth to exchange data, for example, the first terminal and the second terminal can transmit information such as the name of a Wi-Fi hotspot group and a Wi-Fi hotspot password through the GATT connection of BLE (Bluetooth Low Energy), so that the search process of Wi-Fi direct connection or Wi-Fi hotspots can be replaced, the second terminal can be rapidly added into the Wi-Fi group, and meanwhile, the safety is improved; subsequently, after the second terminal joins the group, the first terminal and the second terminal can also connect the device information of the terminals in the interactive group and the like through the GATT.

The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.

As shown in fig. 2, an embodiment of the present invention provides a system for device information interaction between terminals, where the system includes: a first terminal 10 and a second terminal 20.

The first terminal 10: the method comprises the steps of scanning a preset BLE broadcast message after a Wi-Fi connection group is established; determining a second terminal selected by a user from a scanned sending end of the BLE broadcast message; and after the GATT connection is established with the second terminal selected by the user and the second terminal is detected to join the Wi-Fi connection group, sending the equipment information of the terminals in the Wi-Fi connection group to the second terminal through the GATT connection.

The second terminal 20: the system comprises a wireless sensor network and a wireless local area network (Wi-Fi) connection group, wherein the wireless sensor network is used for scanning a Wi-Fi connection group and sending a preset BLE broadcast message after receiving a Wi-Fi connection group joining instruction triggered by a user; determining that a Wi-Fi connection group established by a first terminal is selected from the scanned Wi-Fi connection groups by a user; and after a GATT connection is established with a first terminal establishing the Wi-Fi connection group selected by the user and the terminal joins the Wi-Fi connection group established by the first terminal, receiving equipment information of the terminal in the Wi-Fi connection group sent by the first terminal through the GATT connection.

According to the scheme, the first terminal scans the preset BLE broadcast message after establishing the Wi-Fi connection group, the second terminal broadcasts the preset BLE broadcast message after selecting to join the group, the message contains the Bluetooth MAC address information of the second terminal, the first terminal can determine the Bluetooth MAC address of the second terminal according to the scanned preset BLE broadcast message of the second terminal and establishes GATT connection with the second terminal, and after the GATT connection is established, the first terminal replaces the original TCP connection to send the equipment information of all terminals in the group to the second terminal through the GATT connection. Those skilled in the art can know that the GATT connection of BLE bluetooth is relatively stable, and the data interaction through the GATT connection of BLE bluetooth can improve the stability of the system and reduce the power consumption of the system due to the use of low power consumption bluetooth.

The embodiment of the invention is based on the application of BLE, firstly, the BLE is introduced and explained:

the connection between BLE devices is established over the GATT protocol. GATT builds on GAP bases. The GAP defines several roles for devices, the main two being: BLE Peripheral devices (Peripheral) and BLE Central devices (Central). BLE peripheral devices, peripheral devices for short, are used to provide data, and are generally low-power consumption devices with a relatively simple structure, such as smart bracelets, bluetooth sphygmomanometers, bluetooth game pads, and the like; the BLE central device is used for connecting other BLE peripheral devices and receiving data provided by the BLE peripheral devices, and generally is a device with a relatively complete function, such as a mobile phone, a Pad, and the like. For example: for example, when a user uses a mobile phone to play an electronic game, the user can operate the electronic game through a touch screen on the mobile phone or connect a bluetooth game handle.

A network topology diagram of a GAP-based BLE broadcast phase is shown in fig. 3, where BLE peripheral devices enable BLE central devices to discover themselves by sending BLE broadcasts, the BLE central devices establish a GATT connection with the BLE peripheral devices according to the scanned BLE broadcasts, one BLE peripheral device may send BLE broadcasts to multiple BLE central devices, but one BLE peripheral device may only connect one BLE central device at a time, once the BLE peripheral device is in a connected state, sending of the BLE broadcasts is stopped, and then the BLE peripheral device is in an invisible state for other BLE central devices, and when the BLE peripheral device is disconnected from the BLE central devices, sending of the BLE broadcasts is continued.

GAP-based GATT-connected network topology As shown in figure 4, one BLE center device can connect a plurality of BLE peripheral devices at the same time, wherein the maximum number of BLE peripheral devices that the BLE center device can connect to is determined by the Bluetooth chip of the BLE center device. After the BLE central equipment and the BLE peripheral equipment establish GATT connection, the BLE peripheral equipment connected to the same terminal equipment can transfer through the BLE central equipment, and equipment information interaction is carried out.

Wherein, BLE peripheral equipment can also be called as broadcast sender, and BLE central equipment can also be called as broadcast receiver. The BLE broadcast sent by the BLE peripheral device is actually embodied in a form of a message, that is, a BLE broadcast message, where the BLE broadcast message may carry information such as a bluetooth MAC address, a device name, and a UUID (universal Unique Identifier) of the BLE peripheral device itself, and the BLE central device determines the bluetooth MAC address of the BLE peripheral device sending the BLE broadcast message according to the scanned BLE broadcast message, and establishes a GATT connection with the BLE peripheral device according to the determined bluetooth MAC address.

The embodiment of the invention has a plurality of flows which are mainly divided into a building process of a Wi-Fi connection group, an interactive flow of equipment information of terminals in the group and a file sharing flow among the terminals in the group; during the process of establishing the Wi-Fi connection group, the first terminal and the second terminal establish a GATT connection through a preset BLE broadcast message, and interact information required by the second terminal to join the Wi-Fi connection group through the GATT connection, wherein in the process, the first terminal is a group establisher and is also BLE center equipment; in the interaction process of the device information of the terminals in the group, when the terminals in the Wi-Fi connection group all have the device information of other terminals in the group, the file group sending can be performed by establishing a TCP connection, and the following specific description is respectively given to each process:

the first process is as follows: a Wi-Fi connection group building process;

the Wi-Fi connection group building process mainly comprises the steps that a first terminal builds a group and other terminals (second terminals) join the group. In the embodiment of the present invention, the establishment of a Wi-Fi connection group by a first terminal and the joining of the Wi-Fi connection group by a second terminal are both implemented based on an application of the present application, where an interface schematic diagram of the application is shown in fig. 5, and a main flow of a user a operating the first terminal to establish the Wi-Fi connection group and a main flow of a user B joining the Wi-Fi connection group established by the first terminal include the following steps:

step 1: with reference to fig. 5, a user a clicks a create group icon in an application interface of a first terminal, and operates the first terminal to create a Wi-Fi connection group;

step 2: after the user a clicks the group creation icon on the first terminal, the first terminal jumps to the application interface shown in fig. 6, and the application interface displays a manner of creating a Wi-Fi connection group, including: the method comprises the steps of establishing a Wi-Fi direct connection mode and a Wi-Fi hotspot mode, wherein correspondingly, a first terminal is a group builder, and if the first terminal establishes a Wi-Fi connection group in the Wi-Fi hotspot mode, the first terminal can also be called as a Wi-Fi hotspot builder.

And step 3: the user a selects one of the two modes of the Wi-Fi hotspot and the Wi-Fi direct connection to create a Wi-Fi connection group, after the group creation is completed, an application interface as shown in fig. 7 is displayed on the first terminal, and assuming that the device name of the first terminal is "Android (Android) _ a", the application interface displays the name of the Wi-Fi connection group created by the first terminal and the device name of a group creator, that is, the device name of the first terminal, and information such as other group member lists in the group, it can be understood that no other terminal is added to the group at this time. Here, the "group member" refers to a terminal connected to a Wi-Fi connection group or a terminal within a WLAN connection group except for a group creator.

And 4, step 4: in the embodiment of the invention, after a Wi-Fi connection group is created by a first terminal, scanning of a preset BLE broadcast message is started at the same time, wherein the preset BLE broadcast message is a BLE broadcast message containing a preset UUID. The first terminal screens BLE broadcast messages through preset UUID information. In this process, the first terminal is also a BLE central device for the group establisher.

And 5: correspondingly, if other terminals need to join the Wi-Fi connection group established by the first terminal, the application also needs to be installed. Assuming that the other terminals include a terminal B, after the application is opened by the user operating the terminal B, the displayed application interface can refer to fig. 6, and the user B clicks the join group icon on the application interface to trigger the terminal B to start the process of searching for the Wi-Fi connection group, as shown in fig. 8, an application interface schematic diagram of searching for the Wi-Fi connection group for the terminal B is shown; meanwhile, the terminal B serving as BLE peripheral equipment starts to send a preset BEL broadcast message and waits for the BLE central equipment to find itself.

After the user B clicks the join group icon of the terminal B, the terminal B jumps to the application interface shown in fig. 9, assuming that the device name of the terminal B is "Android _ B", the application interface displays information such as the device name of the second terminal and the scanned connectable group list, and the terminal B adds the scanned group to the connectable group list.

Step 6: after a first terminal serving as BLE center equipment scans a preset BLE broadcast message sent by a terminal B, the Bluetooth MAC address of the terminal B is determined according to the scanned preset BLE broadcast message, and GATT connection is established with the terminal B according to the determined Bluetooth MAC address.

And 7: the terminal B receives group information sent by the first terminal through GATT connection, and when the user B selects one of the groups in the connectable group list scanned by the user B on the terminal B, the terminal B is triggered to send a request for establishing Wi-Fi connection to the group establisher of the group, that is, after the user B operates the terminal B to select a group named "Android _ a" on the application interface shown in fig. 6, the terminal B sends a request for establishing Wi-Fi connection to the group establisher (i.e., the first terminal) who establishes the group.

And 8: if the Wi-Fi connection group is a Wi-Fi direct connection group, the first terminal displays an application interface shown in fig. 10 after receiving a connection establishment request sent by the terminal B, and after the user clicks an accept button of the first terminal, the first terminal sends a response agreeing to establish Wi-Fi connection to the terminal B. If the Wi-Fi connection group is a Wi-Fi hotspot group, the first terminal can directly establish Wi-Fi connection after receiving a connection establishment request sent by the terminal B, and a connection invitation dialog box cannot pop up.

If the Wi-Fi connection group is a Wi-Fi direct connection group, due to the characteristic of Wi-Fi direct connection, after receiving a response of agreeing to establish Wi-Fi connection fed back by the first terminal, the terminal B does not need to perform password verification, and after obtaining the agreeing response of the first terminal, the terminal B can be directly added into the Android _ A group;

in addition to sending the group information such as the name and the group password of the Wi-Fi connection group to the terminal B through GATT connection, the method for joining the Wi-Fi connection group in the embodiment of the present invention may further manually input the group password or the terminal B may join the Wi-Fi connection group created by the first terminal by scanning the two-dimensional code shown in fig. 11, where the two-dimensional code is the two-dimensional code of the Wi-Fi connection group created by the first terminal (group creator) and includes the information such as the name and the group password of the group.

The above-described complete process of joining the terminal B to the "Android _ a" group established by the terminal a. At this time, the terminals in the group include "Android _ a" and "Android _ B", that is, the first terminal and the terminal B. Schematic diagrams for viewing the group information through respective applications of the first terminal and the terminal B are shown in fig. 12 and 13, respectively: FIG. 12 is a schematic diagram of an interface of the application related to group information displayed by the first terminal; fig. 13 is a schematic diagram of an interface of the application related to the group information displayed by the terminal B.

By analogy, if other terminals also join the group, the step of joining the group by the other terminals may refer to the complete flow of the terminal B, which is not described herein again.

It should be noted that, the above steps are only examples, and in the process, after the first terminal creates the Wi-Fi connection group, the second terminal scans the Wi-Fi connection group of the first terminal again, and when in actual use, there is no sequential requirement that the user a operates the first terminal to create the Wi-Fi connection group and the user B operates the second terminal to scan the Wi-Fi connection group.

Further, the first terminal and the second terminal in the embodiment of the present invention both need to turn on bluetooth and Wi-Fi functions. In the building process of the Wi-Fi connection group, the first terminal and the second terminal which start Bluetooth and Wi-Fi functions establish GATT connection through interactive preset BLE broadcast messages, and establish group information such as passwords and the like required by Wi-Fi connection through GATT connection interaction. The preset BLE broadcast message is a BLE broadcast message containing a preset UUID. The first terminal screens BLE broadcast messages through preset UUID information. The preset BLE broadcast message in the device information interaction flow between terminals provided by the invention is introduced as follows:

as shown in fig. 14, a schematic structural diagram of a BLE broadcast message format according to an embodiment of the present invention is provided.

The BLE broadcast message comprises the following four parts:

preamble (Preamble): the broadcast channel is fixed to 10101010b, and the data channel is 10101010b or 01010101 b;

access Address: the broadcast channel is fixed to 0x8E89BED6, the data channel is a random value, different connections have different values, and the data channel is used between two devices after the connection is established;

CRC: CRC checking;

PDU: as shown in FIG. 15, the PDU includes a PDU Header and PDU Payload data;

as shown in fig. 16, the PDU Header includes a PDU Type (Type) for representing the Type of the BLE broadcast packet, where the PDU Type is used to represent the Type of the BLE broadcast packet, and mainly includes: connectable non-directional broadcasts, connectable directional broadcasts, non-connectable non-directional broadcasts, scannable non-directional broadcasts, and the like.

As shown in table 1 below, the maximum length of a PDU Payload data packet of this type is 37 bytes, where AdvA is a broadcast device address part including a bluetooth MAC address of a broadcast sender and is 6 bytes, and AdvData is a PDU data part including two parts, namely, significant (valid data) and non-significant (invalid data), and is 31 bytes.

TABLE 1 BLE broadcast message-PDU Payload structure

AdvData is described in detail below, and includes, but is not limited to, the following:

1, a valid data portion;

the valid Data portion contains a number of broadcast Data units called AD Structure, which contains Length and Data. As shown in fig. 17, the composition of the AD Structure includes, but is not limited to, the following:

1) the Length indicates the Length of Data included after the Length in the AD Structure, that is, the Length of Data.

2) AD Type, which indicates the Type of content represented by AD Data, such as device name, UUID, etc.;

3) AD Data, specific Data content.

For example, the content 020106 of an AD Structure is 02 for Len (indicating that the next 2 bytes of content all belong to AD Structure 1), 01 for AD Type, and 06 for AD Data.

2, invalid data portion;

the length of AdvData in PDU Payload must be 31 bytes, if the valid data part is less than 31 bytes, then it is complemented with 0, and the data in this part is invalid.

The AD types involved in the embodiments of the present invention include, but are not limited to, the following types, which are described below:

type 1: incomplete 16-bit UUID information;

an important concept in BLE applications is UUID, which identifies bluetooth services and communication feature access attributes, with different access methods being used for different bluetooth services and attributes.

Three types of service UUID formats are defined in the bluetooth broadcast, namely, a 16-bit UUID, a 32-bit UUID and a 128-bit UUID. The difference between complete and incomplete is that the device supports various service UUIDs, but only broadcasting a part of the services is called incomplete, and the embodiment of the invention adds a self-defined service in a broadcast data packet, so that the monitoring broadcaster Observer can determine an available device supporting combined transmission of bluetooth and Wi-Fi P2P by judging whether a scanned BLE broadcast message carries UUID information corresponding to the self-defined service.

In the embodiment of the invention, 0x02 represents incomplete 16-bit UUID information, and if the AD Type is 02, the content of AD Data is incomplete UUID information.

Such as: if the self-defined Service name is My _ Service _ UUID, and if the My _ Service _ UUID generated by using the UUID random generator is E953, when the UUID obtained by analyzing the received BLE broadcast message contains E953, the BLE broadcast message is represented as a preset BLE broadcast message.

For example, the following steps are carried out: the AD Structure 1 in the BLE broadcast message received by the broadcast receiver is 030253E 9, where length is 03, 3 bytes after length belong to AD Structure 1, AD Type is 02, the content of AD Data is UUID information, and the corresponding UUID information is E953, that is, My _ Service _ UUID, then the broadcast receiver determines that the BLE broadcast message is a preset BLE broadcast message.

It should be noted that, the My _ Service _ UUID is E953, which is only an example, for example: the complete 128-bit UUID can be used and randomly generated by a random generator, wherein the AD Type of the BLE broadcast message corresponding to the 128-bit UUID is 0X07, any value representing meaning or Type is not limited to a fixed real number, and any value or length combination meeting the condition requirement is suitable for the invention.

Type 2: a device name;

in the embodiment of the invention, 0x08 represents equipment abbreviation, 0x09 represents equipment full name, correspondingly, AD Data is a character string of names, and if AD Type is 08, the AD Data is the abbreviation of the names of the equipment; if the AD Type is 09, the AD Data device is called fully, and the added part is to enable the broadcast monitor Observer to obtain the device name of the Broadcaster, so as to display the device name, which is convenient for the user to view.

For example, the content of an AD Structure is 0E 09454 d 393330342046696E 646 d 65, where Len is 0E (indicating that the contents of the next 14 bytes all belong to the AD Structure 3), AD Type is 09 for the device generic name, and AD Data is 454 d 393330342046696E 646 d 65 for "E" M "9" 3 "0" 4 "space" F "i" n "d" M "E' (see ASCII code hexadecimal).

Type 3: customizing data;

in the embodiment of the invention, 0xFF represents vendor self-defined data, the first two bytes represent vendor ID, the default is 6F4D, and the rest are added according to requirements, so that the data content in the data can be self-defined.

It should be noted that, because the first terminal may create the Wi-Fi connection group in two ways, namely, the Wi-Fi direct connection and the Wi-Fi hotspot, the Wi-Fi connection group in the embodiment of the present invention also includes a Wi-Fi direct connection group and a Wi-Fi hotspot group. In the following, a Wi-Fi direct connection mode and a Wi-Fi hotspot mode are described by taking the first terminal as a group creator and the terminal B as one of the second terminals, respectively:

establishing a first mode and a Wi-Fi direct connection mode;

the Wi-Fi connection group created by the first terminal in a Wi-Fi direct connection mode is a Wi-Fi direct connection group, and after the group creation is completed, the first terminal configures an IP address for the first terminal, such as: 192.168.0.1.

after the terminal B selects to join the group, the terminal B sends a request for establishing the Wi-Fi direct connection to the first terminal, and the first terminal feeds back a response for agreeing to establish the Wi-Fi direct connection or refusing to establish the Wi-Fi direct connection to the terminal B.

And if the response which is sent to the terminal B by the first terminal and agrees to establish the Wi-Fi direct connection is received by the terminal B, the terminal B determines to join the Wi-Fi direct connection group.

And after the first terminal sends a response agreeing to establish the Wi-Fi direct connection to the terminal B, configuring different IP addresses of the same network segment as the first terminal for the terminal B. It can be understood by those skilled in the art that the IP addresses of the terminals in the same lan are necessarily different, for example: the IP address of the first terminal is 192.168.0.1, and the first terminal configures 192.168.0 for terminal B, the IP addresses in the network segment other than 192.168.0.1, for example, the IP address configured for terminal B by the first terminal is 192.168.0.2.

By analogy, if other terminals join the Wi-Fi direct connection group, the complete process of the terminal B may be referred to, and details are not described here.

Establishing a second mode and a Wi-Fi hotspot mode;

the Wi-Fi connection group created by the first terminal in the Wi-Fi hotspot mode is a Wi-Fi hotspot group, after the group creation is completed, the same as the Wi-Fi direct connection mode is achieved, and the first terminal configures an IP address for the first terminal.

The terminal B selects to join the Wi-Fi hotspot group, and it should be noted that, because the group is a Wi-Fi hotspot group, the terminal B may need to input a password of the Wi-Fi hotspot to verify and then join the group. In the embodiment of the invention, the mode that the terminal B joins the group is various, for example, after a certain Wi-Fi hotspot group is selected, the password of the group is manually input; or join the group by scanning the group two-dimensional code on the first terminal, and the like, it can be understood that the group two-dimensional code of the group on the first terminal includes information such as the name and the password of the group.

And after the terminal B selects to join the group, sending a request for establishing the Wi-Fi hotspot connection to the first terminal, and feeding back a response for agreeing to establish the Wi-Fi hotspot connection or refusing to establish the Wi-Fi hotspot connection to the second terminal by the first terminal.

And if the first terminal sends a response to the terminal B for agreeing to establish the Wi-Fi hotspot connection, the terminal B determines to join the Wi-Fi hotspot group after receiving the response.

And after the first terminal sends a response agreeing to establish the Wi-Fi hotspot connection to the terminal B, configuring different IP addresses in the same network segment as the first terminal for the terminal B.

The device information includes an IP address of the terminal, a MAC address of the terminal, a device name, and the like. There are various specific ways for the terminal to report its own device information, such as: reporting in a point-to-point mode, in a broadcast mode, in a multicast mode or in a GATT connection.

Correspondingly, after receiving the device information reported by each terminal in the group, the first terminal stores the received device information of each terminal into a device list which is locally connected with the Wi-Fi hotspot, and if any terminal exits the group, the first terminal needs to delete the device information of the terminal which exits the group from the device list which is locally connected with the Wi-Fi hotspot. Similarly, for the Wi-Fi direct connection group, when acquiring the device information of the terminal in the group, the group creator may also perform statistics and update in a manner of a device list of a local connected group, and notify the updated device information in the device list to other terminals in the group. A specific procedure for notifying the first terminal of the device information of the terminals in the group to the terminals in the group through the procedure will be described below.

And a second process: the interactive process of the equipment information of the terminals in the group;

fig. 18 is a network topology diagram of a Wi-Fi connection group based on GATT connection according to an embodiment of the present invention, where the Wi-Fi connection group includes a first terminal, a terminal B, and a terminal C, and the first terminal replaces device information such as an IP address of a terminal in an original TCP connection and a second terminal interaction group through GATT connection;

and when the first terminal detects that a newly-added Wi-Fi connection group is established or a quit of the Wi-Fi connection group is detected, the updated equipment information of the terminals in the group is sent to each terminal equipment in the current group one by one through GATT connection.

And a third process: sharing data among terminals in the group;

when the terminals in the Wi-Fi connection group have the equipment information of other terminals in the group, the TCP connection can be established with other group members according to the IP address information to perform file group sending.

As shown in fig. 19, a schematic diagram of a complete interaction flow of device information interaction between terminals provided in the embodiment of the present invention includes the following steps:

step 1900, the first terminal establishes a Wi-Fi connection group and starts scanning a preset BLE broadcast message;

step 1901, clicking a joining group of the terminal B, and starting to send a preset BLE broadcast message;

step 1902, after scanning a preset BLE broadcast message of terminal B, the first terminal sends a request for establishing GATT connection to terminal B;

step 1903, terminal B sends a response to the first terminal agreeing to establish GATT connection;

step 1904, the first terminal sends the group information of the Wi-Fi connection group to terminal B through GATT connection;

step 1905, the terminal B receives the group information sent by the first terminal through GATT connection, and joins the Wi-Fi connection group selected by the user according to the group information;

step 1906, the first terminal obtains and stores the device information of terminal B including the IP address, and sends the device information of the first terminal itself to terminal B through GATT connection;

step 1907, clicking a joining group of the terminal C, and starting to send a preset BLE broadcast message;

step 1908, after scanning the preset BLE broadcast message of terminal C, the first terminal sends a request for establishing GATT connection to terminal C;

step 1909, terminal C sends a response to the first terminal agreeing to establish GATT connection;

step 1910, the first terminal sends the group information of the Wi-Fi connection group to terminal C through GATT connection;

step 1911, terminal C receives the group information sent by the first terminal through GATT connection, and joins the Wi-Fi connection group selected by the user according to the group information;

step 1912, the first terminal acquires and stores the device information of the terminal C including the IP address, and sends the device information of the first terminal itself and the terminal C to the terminal B through GATT connection, and sends the device information of itself and the terminal B to the terminal C;

step 1913, receiving the device information sent by the first terminal through GATT connection, and establishing TCP connection with terminal C according to the IP address of terminal C;

step 1914, receiving the device information sent by the first terminal through GATT connection, and establishing TCP connection with terminal B according to the IP address of terminal B;

in step 1915, the terminals in the group share data through TCP connections.

Here, step 1906 and step 1912 are only examples, and the first terminal may send the device information of all current terminals in the Wi-Fi connection group to the terminals of the group, for example: for step 1906, the first terminal may send its own and device information of terminal B to terminal B; for step 1912, the first terminal may transmit device information of itself, terminal B, and terminal C to terminal B and terminal C.

It should be noted that there is no order relationship between step 1900 and step 1901, which is only an example. Between step 1913 and step 1914, it is only indicated that the terminal B/terminal C establishes TCP connection with other terminals in the group, but not that both terminals need to initiate TCP connection, and if terminal B establishes TCP connection with terminal C first, terminal C may directly perform data sharing through the established TCP connection with terminal B.
