Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

For the convenience of understanding the technical solution of the present application, first, the technical problems of the embodiments of the present application will be described.

Referring to fig. 1, fig. 1 illustrates a scene diagram of a cell phone in some embodiments in communication with a navigator. As shown in fig. 1, in this scene diagram, a cell phone 10 and a navigator 20 are included. The navigator may be understood as an external GPS device independent of the mobile phone, and the navigator 20 may perform a satellite searching operation to obtain navigation data sent by satellites and generate NMEA data in a unified format of national marine electronics association (National Marine Electronics Association, NMEA). The handset 10 may establish a communication connection with the navigator 20 and obtain navigation data from the navigator 20 to obtain its own location information. Thus, even if the navigation chip of the mobile phone fails or the acquired navigation is not accurate enough, the navigator 20 can acquire the position information of the mobile phone, so as to realize the positioning navigation function. In addition, even the electronic equipment without the navigation chip, such as a tablet, can realize positioning navigation, thereby meeting the requirement of a user on the auxiliary external GPS equipment.

In order to ensure the positioning accuracy, the mobile phone and the navigator should keep a relatively short distance, so that the mobile phone and the navigator need to be connected through close-range communication. In some aspects, both communicate using a bluetooth connection. However, in some embodiments, to implement the communication between the mobile phone 10 and the navigator 20 and to implement the positioning for displaying navigation in the interface of the mobile phone, a navigation-assisting software, such as a bluetooth navigation application (Bluetooth Global Positioning System application), needs to be downloaded in the mobile phone, and the communication connection between the mobile phone and the navigator is implemented through the bluetooth navigation application. However, this solution is very complex to operate. In the following embodiments, the positioning process of this scheme is described.

Referring to fig. 2, fig. 2 illustrates a flow chart for enabling modules in a cell phone to interact with a navigator based on user operations in some embodiments. As shown in fig. 2, the handset includes a setting apk module (setting apk), a Bluetooth apk module (Bluetooth apk), a location service module (i.e., a location based service (Location Based Service, LBS), also called a mobile location service), a map application, and a Bluetooth navigation application. The Bluetooth navigation application is downloaded before the mobile phone is in communication connection with an external navigator.

As shown in fig. 2, in step (1), the user downloads and installs the bluetooth navigation application through an application marketplace or other website in the handset. Step (2), when the installation of the Bluetooth navigation application is completed, the user needs several operations in succession, for example, 1. Open the setup module (settings apk); 2. finding a version number, clicking the version number for multiple times, and entering a developer mode; 3. in the developer option menu, "simulation location information application" is selected; 4. the "bluetooth navigation application" is selected under the selection application. In step (3), the pairing of the mobile phone and the external navigator is completed, for example, the navigator is searched in the setting application, and the pairing is clicked. When the navigator is started, namely in power-on operation, the navigator is automatically paired with the Bluetooth module of the mobile phone. In step (4), before each navigation, the user needs to click on the desktop of the mobile phone and open the Bluetooth navigation application, and input a connection instruction for establishing a navigator through a prompt in a corresponding interface of the Bluetooth navigation application. The Bluetooth navigation application receives the instruction input by the user, constructs the SPP client, and executes the SPP client in the step (5). And (5) initiating a command of connecting a Bluetooth protocol stack serial port protocol (Serial Port Profile, SPP) to the Bluetooth module, and receiving the command by the Bluetooth module and establishing SPP connection with the navigator. After the navigator establishes a connection, satellite signals are received, data sent by satellites are obtained, and navigation data in NMEA format is constructed. In step (6), the navigator sends NMEA data in a uniform format to the bluetooth module based on the SPP connection. The Bluetooth module calls back the SPP client, sends NMEA data to a Bluetooth navigation application with the SPP client, analyzes the NMEA data by the Bluetooth navigation application to obtain the position information of the current device, and executes the step (7). In step (7), the bluetooth navigation application injects location information into the location service module through the analog location service provider interface. Step (8), the user uses the map application, i.e. opens the map application, and the location service module performs step (9). And (9) reporting the position information to a map application. The user knows the position of the user according to the position display in the map application and performs navigation operation, so that the positioning process based on the navigator is realized.

In the positioning process, in the steps (1), (2), (3), (4) and (8), user operation is needed, the number of times of user operation is large, and the operation is frequent, so that the user experience is low. In particular in step (2), since in the currently designed navigation architecture multiple GPS data sources may be allowed, these data sources may be handled by two location services, or location providers, e.g. a home location provider (Original Location Provider) and an analog location provider (Mock Location Provider). However, since the two location services are mutually exclusive, one of them can be selected only according to the device support situation.

Referring to fig. 3a and 3b, fig. 3a illustrates a flow diagram of NMEA data from within a navigator to a handset in some embodiments; fig. 3b shows a schematic diagram of a location service corresponding to fig. 3 a. As shown in fig. 3a, the mobile phone includes a bluetooth module, a bluetooth navigation application, and a location-based service map application. The navigator can search for the star to obtain and generate NMEA data and transmit the data to the handset, and the transmission process includes steps (1) - (6) in fig. 2. The bluetooth module obtains NMEA data and transmits the NMEA data to the bluetooth navigation application, the bluetooth navigation application comprises an analog position provider, and the data is transmitted to the position service module based on the analog position provider and then transmitted to the map application, and the map application corresponds to (7) in fig. 2. In connection with the architecture diagram shown in fig. 3b, the architecture diagram includes a Location based service application (Location Based Service application, LBS app), location management (Location Manager), as well as a home Location provider and a simulated Location provider. Wherein the location service application may record the location. The simulated location provider includes a bluetooth navigation agent module, i.e., for communication connection with the bluetooth module. Therefore, in the current scheme depending on the bluetooth navigation application, only the analog location provider can be selected, and the selection process of the analog location provider can refer to the description of the step (2) in fig. 2, which is very cumbersome to operate.

It should be noted that the simulated location provider may also include other proxy modules, such as a differential global positioning system (Differential Global Positioning System, DGPS), a corresponding Component Object Model (COM), a WIFI proxy corresponding network (network), and the like, which are not described in the present application.

The following describes further the operation procedure of selecting the bluetooth navigation application under the simulated location information application in step (2) in fig. 2 with reference to the interface operation chart.

Referring to fig. 4, fig. 4 illustrates an operational interface diagram of location service selection in some embodiments. As shown in fig. 4 (a), the user opens the setup interface 410, clicks the option "about cell phone" at the interface 410, and enters the interface 420 about cell phone as shown in fig. 4 (b). The option "version number" is found in interface 420 and after clicking the version number multiple times, the previous menu is returned to enter the system and update interface 430 as shown in fig. 4 (c). In interface 430, select "developer option", then enter developer option interface 440 as shown in fig. 4 (d). In interface 440, the user clicks "select simulated location information application", which corresponds to the simulated location information application in step (2) in FIG. 2, i.e., the simulated location provider. Thereafter, the user enters a select application interface 450 as shown in fig. 4 (e), where the interface 450 includes an option for a bluetooth navigation application, and the user selects the bluetooth navigation application. And finishing the selection process of the simulation position information application. It follows that this procedure is very cumbersome and the user experience is not high.

The process of establishing a connection instruction with the navigator by user input in step (4) in fig. 2 will be further described with reference to an interface operation chart.

Referring to fig. 5, fig. 5 illustrates an operational interface diagram of user input of a connection establishment instruction with a navigator in some embodiments. As shown in fig. 5 (a), in the desktop interface 510, click on an icon of the bluetooth navigation application, open the bluetooth navigation application, enter the connection interface 520 shown in fig. 5 (b), and select the "connect" option in the interface 520, at this time, the bluetooth navigation application initiates an SPP connection, and finally realizes the SPP connection with the navigator (refer to the whole process in fig. 2 (4)). After the user clicks on the connect, the interface 530 shown in fig. 5 (b) is entered, and the connect option is now the "disconnect" option. The user can click "off" to disconnect the navigator from the handset. This procedure is also cumbersome.

In the above positioning scheme, the operation process of the user is complicated, and the user experience is poor. In addition, because the Bluetooth navigation application needs to be downloaded and installed, the application program not only occupies the memory of the mobile phone, but also consumes very fast power. It is also necessary to manually shut down the bluetooth navigation application when the navigation exits, otherwise the power will soon be exhausted. Therefore, the bluetooth navigation application, which is an app for relaying NMEA data, is easily turned off by the system, and if navigation is being performed, navigation cannot be performed.

In view of the above-mentioned problems, the present application provides a positioning method based on bluetooth transmission, which can be applied to a system formed by a mobile phone and a navigator, wherein when the mobile phone receives an operation (first operation) of pairing a user with the navigator bluetooth, for example, the user turns on the bluetooth by setting, discovers peripheral navigators by a discovery function of the bluetooth, and selects the operation of the navigator after discovery. The mobile phone responds to the operation of Bluetooth pairing with the navigator, and the transmission channel for transmitting the first navigation data is determined through negotiation between the Bluetooth module and the navigator. The Bluetooth module registers, monitors and acquires the navigation data after determining the transmission channel so as to communicate with the navigator when receiving the navigation instruction of the user, so that the navigator performs the star searching action, and NMEA data is acquired.

When the mobile phone receives an operation (second operation) of opening the map application by the user, for example, the user clicks the map application in the mobile phone interface. In response to the operation, the mobile phone establishes a bluetooth connection with the navigator through the bluetooth module, and establishes a transmission channel through which the bluetooth module obtains NMEA data (first navigation data) from the navigator. The Bluetooth module can directly process and analyze NMEA data and send the NMEA data to the location service module. The position service module determines current position data based on the processed NMEA data and reports the position data to a map application so that the map application displays the position data.

According to the positioning method based on Bluetooth transmission, the function of relaying NMEA data is moved to a Bluetooth module (system application), NMEA data is directly obtained through the Bluetooth module, and the Bluetooth module and the location service module can directly transmit the analyzed NMEA data in an indiscriminate manner, and in the process, auxiliary navigation software is not needed to be downloaded for assistance. The method is simple to operate, does not need to additionally download the application, and can save space. In addition, compared with the scheme adopting the Bluetooth navigation application, the method reduces the running of one application program, can reduce the power consumption and greatly improves the user experience.

In the above embodiments, the mobile phone is described as an example of the electronic device. In some embodiments, the electronic device may also be a tablet computer, personal computer (personal computer, PC), notebook computer, personal digital assistant (personal digital assistant, PDA), in-vehicle device, web television, wearable device, or the like product with a display interface. In addition, the above embodiment is described taking a navigator as an example of a navigation apparatus. In some embodiments, the navigation device may be a cell phone, tablet, personal computer (personal computer, PC), notebook, wearable device, etc. with navigation functionality. The present application does not particularly limit the existence form of the electronic device.

The following describes in detail a positioning method based on bluetooth transmission according to the embodiment of the present application, in combination with two bluetooth connection scenarios, i.e. classical bluetooth and bluetooth low energy. The method provided by the embodiment of the application can be applied to the electronic equipment with the hardware structure shown in the figure 6 and the software structure shown in the figure 7. Or more or less components than illustrated, or some components may be combined, or some components may be separated, or different components may be arranged, or the like in hardware and software configurations.

For convenience of explanation, the following embodiments are exemplified by taking an electronic device as a mobile phone and a navigation device as a navigator.

Referring to fig. 8, fig. 8 shows a flowchart of a positioning method based on classical bluetooth transmission according to an embodiment of the present application. As shown in fig. 8, the method is performed by a mobile phone and a navigator, and is suitable for a scene that the navigation module of the mobile phone is insufficient or fails and positioning needs to be realized by means of an external navigator. The mobile phone comprises a Bluetooth module, a location service module and a map application, and the function modules are all functions of the system. The method includes S811-S820.

S811, the Bluetooth module of the mobile phone is matched and connected with the navigator.

Here, the Bluetooth module refers to a classical Bluetooth (BT), which generally refers to a module supporting Bluetooth protocol below 4.0, and is generally used for transmission with relatively large data volume. The bluetooth transmission protocol used by the bluetooth module may include Radio Frequency Communication (RFCOMM), logical link control and adaptation protocol (Logical Link Control and Adaptation Protocol, L2 CAP), and may also include service discovery protocol (Service Discovery Protocol, SDP), serial protocol (Serial Port Profile, SPP), hands Free Profile (HFP), and the like.

In the embodiment of the application, the user may use a conventional bluetooth pairing operation, for example, bluetooth is turned on from a setting, bluetooth automatically searches for a peripheral device, for example, searches for a navigator, and after the user clicks the navigator (the first operation), the mobile phone communicates with the navigator and mutually authenticates to complete the pairing process. This establishes the basis for subsequent connections and data transmission. Once pairing is successful, when the user navigates for the second time or more, the mobile phone and the navigator are connected in a Bluetooth mode, pairing operation is not needed, bluetooth of the mobile phone and the navigator is directly started, and Bluetooth connection is automatically established between the mobile phone and the navigator, so that data transmission is facilitated.

S812, the mobile phone negotiates with the navigator and determines a transmission channel.

For example, the bluetooth module negotiates with the navigator whether or not to support the connection of classical bluetooth of the external navigator. If so, the transmission channel is further negotiated, and if not, the subsequent connection operation is not performed.

In some embodiments, the handset, after pairing with the navigator, takes a negotiated transport channel based on SDP service discovery. Such as a transmission channel for transmitting NMEA data. In the embodiment of the application, the bluetooth protocol of the navigator may be the same as that of the mobile phone. Both determine a transmission channel for transmitting NMEA based on their own capabilities, wherein the transmission channel may be a transmission channel established based on any of L2CAP channel (channel), L2CAP request-response (SPP), and HFP. For example, if it is determined to establish an L2CAP channel, during the subsequent data transmission, the L2CAP channel is directly used to establish a transmission channel, and NMEA data is transmitted based on the transmission channel.

In the embodiment of the application, after the Bluetooth module of the mobile phone negotiates with the navigator to obtain a transmission channel, the Bluetooth module registers and monitors satellite searching behaviors, so that once the Bluetooth module receives a satellite searching instruction, the connection is initiated like the navigator, and the navigator is informed to perform the satellite searching behaviors so as to acquire navigation data from satellites.

S813, the map application receives the navigation operation (second operation) input by the user, and initiates the instruction of navigation to the location service module.

For example, the user clicks an icon of the map application or an operation of the navigation application in the interface of the mobile phone, the map application obtains the operation instruction, and sends the instruction of navigation to the location service module.

S814, the location service module stores the star searching instruction and sends the star searching instruction to the Bluetooth module.

The position service module not only can send a star searching instruction to the Bluetooth module, but also can inform the GPS chip of star searching behavior when the mobile phone has the GPS chip with the star searching function, so that two groups of NMEA data can be obtained.

S815, the Bluetooth module initiates Bluetooth connection to the navigator, and establishes Bluetooth connection with the Bluetooth module after the navigator receives the connection request. The process of the bluetooth connection may refer specifically to the bluetooth connection method of the prior art, which is not described in detail in this application.

S816, the Bluetooth module initiates a transmission channel request of NMEA data transmission to the navigator to establish a transmission channel. For example, in S812, the transmission channel determined by the bluetooth module and the navigator is an L2CAP channel protocol transmission channel, and at this time, the navigator establishes an L2CAP channel protocol transmission channel with the bluetooth module and transmits NMEA data (first navigation data) through the transmission channel.

In addition, in some embodiments, a transmission channel may also be established using HCI L2CP ehco request-response over L2CAP channel and NMEA data may be transmitted. An SPP transmission channel may also be established to transmit NMEA data. When the SPP transmission channel is established, the Bluetooth module needs to establish a new SPP client (client), and communicates with the SPP server of the navigator to complete the establishment of the transmission channel. In other embodiments, since the NMEA data is in AT command format, it may also be transmitted over the transmission channel of HFP signaling.

In the embodiment of the present application, when the navigator receives a request for a transmission channel of NMEA data initiated by the bluetooth module, a satellite searching operation is started to acquire navigation data from satellites, for example, the number of satellites, the positions of the satellites, the moving track of the satellites, the distance between the satellites and the navigator, and the like. The navigator obtains the navigation data and encapsulates the navigation data into NMEA (network management and analysis) format data unified by the GPS navigation equipment, namely NMEA data, so as to realize the unification of the data formats.

S817, the Bluetooth module and the location service module establish a GPS.hal data channel.

In one embodiment of the present application, the data channel of gps.hal may be implemented by bluetooth navigation agent (hal) and navigation abstraction layer library (hal) as in fig. 7. The Bluetooth navigation agent (hal) analyzes the NMEA data and encapsulates the NMEA data into non-NMEA data (NNMEA data) in a hal format which can be in a hal layer transmission format, so that the non-differential transmission in the hal layer can be realized, and the integrity of the data is ensured. The specific implementation of this channel can refer to the prior art for implementing a data transmission process with respect to a GPS Hal in the Android GNSS Hal service, and will not be described in detail here.

S818, the bluetooth module injects NMEA data to the location service module. That is, NNMEA data can be transmitted to the location service module through the data channel of GPS.hal, so that the transmission process of complete data is ensured to the greatest extent.

And S819, combining the data transmitted by the Bluetooth navigation agent by the position service module.

In the embodiment of the application, after NNMEA data is obtained, the location service module analyzes the data, and calculates the distance between the mobile phone and the satellite based on the analyzed data, so that the current location information is determined.

S820, the location service module reports the current location information to the map application. The user can know the current position in the map application interface, and the quick positioning process is realized.

The whole process of S811-S820 is the operation of the user when the user first uses the mobile phone to establish bluetooth connection with the navigator, and the process of realizing data transmission. When the Bluetooth connection is not established for the first time, the user does not need to perform the operation of pairing connection. Positioning can be achieved by simply clicking on the map application.

According to the positioning method, in the whole positioning navigation process, a user only needs to execute Bluetooth pairing (first operation) of the mobile phone and the navigator. After that, when navigation is needed, the map application (second operation) is clicked, so that accurate positioning can be realized, and the operation process is very simple. In addition, the additional downloading of the application program is not needed to assist in positioning, so that space is saved, electricity consumption caused by running the downloaded application can be avoided, and user experience is greatly improved.

The positioning method of classical bluetooth transmission in the embodiment of the present application is described below with reference to a flow chart of data between modules in a mobile phone.

Referring to fig. 9, fig. 9 shows a main configuration of a mobile phone and a navigator and a flow chart of NMEA data from the navigator to the inside of the mobile phone according to an embodiment of the present application. The following aspects explain the flow of data during implementation of the embodiments of the present application, and may also be used to generally describe the architecture of a cell phone and a navigator in conjunction with the flow of data between the navigator and the cell phone.

The mobile phone comprises a Bluetooth module, a Bluetooth location service and a map application, and a navigator for establishing a Bluetooth connection with the mobile phone.

As shown in fig. 9, the flow chart is mainly divided into five main processes, i.e., S910-S940.

Wherein, at S910, the snma data is transmitted from the navigator to the handset. The transmission channel may be a transmission channel established based on any one of L2CAP channel protocol, L2CAP echo request-response, SPP and HFP. The transmission channel establishment process may refer to S811-S816 in fig. 8.

At S920, the bluetooth module of the mobile phone includes an NMEA data identification module, and when the bluetooth module obtains NMEA data based on the transmission channel, the bluetooth module transmits the NMEA data to the NMEA data identification module.

In the embodiment of the application, the NMEA data identification module determines the format of the obtained data, and when the NMEA data identification module obtains the data with the data format of NMEA data, the NMEA data is transmitted to the bluetooth navigation agent module (hal). Otherwise, the data is processed according to the conventional processing mode of the Bluetooth module without being transmitted to the Bluetooth navigation agency module (hal), so that the Bluetooth navigation agency module (hal) is ensured to transmit NMEA data.

The Bluetooth navigation agent module (hal) analyzes NMEA data, encapsulates the NMEA data into hal-format NNMEA data which can be transmitted in a hal layer, and is convenient for transmitting the data to a navigation abstraction layer library, so that the integrity of the data is ensured.

At S930, the bluetooth navigation agent module (hal) transparently passes NNMEA data to the navigation abstraction layer library (corresponding to libgps. So (hal)) based on the channel established with the navigation abstraction layer library. This step corresponds to S818-S820 in fig. 8, and specific implementations of the transmission may be described with reference to S818-S820 in fig. 8.

At S940, the navigation abstraction layer library obtains NNMEA data, parses the data to obtain hal format data corresponding to ***, and calculates parameters such as a distance between a mobile phone or a navigator and a satellite based on the parsed data to obtain current location information. And finally, reporting the position information to a navigation position provider and position management until the map application is finished, so that the mobile phone is positioned.

It should be noted that, in some embodiments, the navigation abstraction layer library may further obtain NMEA data (second navigation data) obtained by the mobile phone navigation chip, and combine the NMEA data obtained by the navigator, and calculate the current position by combining the two sets of NMEA data. Thereby improving the accuracy of positioning.

The bluetooth transmission-based positioning method of the embodiments of the present application is implemented in a device utilizing bluetooth low energy (Bluetooth Low Energe, BLE) is explained below.

Referring to fig. 10, fig. 10 shows a flowchart of a positioning method based on bluetooth low energy transmission according to an embodiment of the present application. As shown in fig. 10, the method is performed by a mobile phone and a navigator, wherein the mobile phone includes a bluetooth module, a location service module and a map application, and the function modules are all functions of the system. The method includes S1011-S1020.

S1011, the Bluetooth module of the mobile phone is matched and connected with the navigator.

Herein, the bluetooth module refers to bluetooth low energy BLE. The composition of the BLE protocol stack includes logical link control and adaptation protocol (Logic link control and adaptation protocol, L2 CAP), attribute protocol (Attribute protocol, ATT) generic attribute profile layer (Generic attribute profile, GATT), etc. The GATT is based on the concept of attributes (Attribute) and services (service), and by encapsulating data in attributes, that is, attribute is used to describe data one by one, each Attribute has a unique identifier (UUID), so that when a device broadcasts, other devices can accurately identify the data through UUID, thereby realizing communication with a designated device. That is, the two devices finally implement communication between the two devices through the BLE protocol stack, and the complete communication process thereof can refer to the communication process of BLE in the prior art, which is not described in detail in the present application.

As shown in fig. 10, in pairing, the GATT service of the navigator is first to be in a start state, so that GATT Client pairing connection with the bluetooth module can be realized, and services and the like can be provided.

It should be noted that, for the operation of the user during pairing, reference may be made to the description of S811 in fig. 8, which is not repeated here.

It should be noted that, the negotiation process between the navigator and the bluetooth module may be the negotiation between the bluetooth module of the navigator and the bluetooth module of the mobile phone.

S1012, the mobile phone negotiates with the navigator GATT capability and determines a transmission channel.

After the mobile phone is matched with the navigator Bluetooth, the Bluetooth module negotiates with the navigator based on the GATT to determine whether NMEA data can be transmitted. And after determining that the satellite can be transmitted, the Bluetooth module registers and monitors satellite searching behaviors, so that when a satellite searching instruction is received, the navigator is informed of satellite searching, and meanwhile, the navigator is ready to initiate BLE broadcasting.

S1013, the map application receives the navigation operation (second operation) input by the user, and initiates the instruction of navigation to the location service module. This step corresponds to S813 in fig. 8, and the description in S813 may be referred to.

S1014, the location service module stores the star searching instruction and sends the star searching instruction to the Bluetooth module. This step corresponds to S814 in fig. 8, and reference is made to the description in S814.

S1015, the Bluetooth module initiates GATT Bluetooth connection to the navigator, and establishes Bluetooth connection when the navigator receives a connection request.

The process is that the Bluetooth module communicates with the GATT service of the navigator through the GATT client and establishes connection. The process of establishing a bluetooth connection with bluetooth low energy in the prior art may be referred to for a specific connection, and will not be described herein.

S1016, the Bluetooth module and the navigator establish an NMAE data transmission channel. Since the capability of transmitting NMEA data has been negotiated in S1012, a data transmission channel may be directly established after the bluetooth connection is established.

S1017, the Bluetooth module and the location service module establish a GPS.hal data channel. This step corresponds to S817 in fig. 8, and specific reference may be made to the description in S817, which is not repeated here.

S1018, the bluetooth module injects NNMEA data into the location services module.

In particular, navigation extraction by a location services module may be performedElephant imageLayer library (libgps. So (hal)) reception. This step corresponds to S818 in fig. 8, and specific reference is made to S818, which is not repeated here.

S1019, the location service module merges the data transmitted by the Bluetooth navigation agent.

S1020, the location service module reports the current location information to the map application. The user can know the current position in the map application interface, and the quick positioning process is realized.

The whole process of S1011-S1020 is the operation of the user when the user first uses the mobile phone to establish bluetooth connection with the navigator, and the process of realizing data transmission. When the Bluetooth connection is not established for the first time, the user does not need to perform the operation of pairing connection. Positioning can be achieved by simply clicking on the map application.

According to the positioning method, the operation process is very simple. Furthermore, no additional download application is required to assist in positioning. Not only saving space, but also avoiding the consumption of electric quantity caused by running downloaded application, so that the user experience is greatly improved.

The following describes a positioning method for bluetooth low energy transmission according to the embodiments of the present application in combination with a flow chart of data between modules in a mobile phone.

Referring to fig. 11, fig. 11 shows a main configuration of a mobile phone and a navigator according to another embodiment of the present invention and a flow chart of NMEA data from the navigator to the inside of the mobile phone. The following aspects explain the flow of data during implementation of the embodiments of the present application, and may also be used to generally describe the architecture of a cell phone and a navigator in conjunction with the flow of data between the navigator and the cell phone.

As shown in fig. 11, the flow chart is largely divided into five main processes, S1110-S1140.

Wherein at S1110, NMEA data is transmitted from the navigator to the handset. The transmission channel may be a GATT transmission channel established based on various components of a BLE protocol stack, such as an L2CAP channel protocol, a GATT protocol, an ATT protocol, and the like. The transmission channel establishment process may refer to S1011-S1016 in fig. 10.

At S1120, the bluetooth module of the mobile phone includes an NMEA data identification module, and when the bluetooth module obtains NMEA data based on the transmission channel, the bluetooth module transmits the NMEA data to the NMEA data identification module. This step corresponds to S920 in fig. 9.

The NMEA data identification module judges the format of the obtained data, and when the NMEA data identification module obtains the data with the NMEA data format, the NMEA data is transmitted to the Bluetooth navigation agent module (hal). Otherwise, the data is processed according to the conventional processing mode of the Bluetooth module without being transmitted to the Bluetooth navigation agency module (hal), so that the Bluetooth navigation agency module (hal) is ensured to transmit NMEA data.

The Bluetooth navigation agent module (hal) analyzes the NMEA data, encapsulates the analyzed data into hal-format NNMEA data which can be transmitted in a hal layer, and is convenient for transmitting the data to a navigation abstraction layer library, so that the integrity of the data is ensured.

At S1130, the bluetooth navigation agent module (hal) transparently passes NNMEA data to the navigation abstraction layer library (corresponding to libgps. So (hal)) based on the channel established with the navigation abstraction layer library. This step corresponds to S930 in fig. 9, and specific reference may be made to the description of S930 in fig. 9.

At S1140, the navigation abstraction layer library obtains NMEA data, parses the data to obtain hal format data corresponding to ***, and calculates parameters such as a distance between the mobile phone or navigator and a satellite based on the parsed data to obtain current location information. And finally, reporting the position information to a navigation position provider and position management until the map application is finished, so that the mobile phone is positioned.

In other embodiments, when a plurality of navigator are connected with the mobile phone bluetooth, the mobile phone can obtain NMEA data from the plurality of navigator, and then calculate the current position information, thereby effectively improving the positioning accuracy and avoiding the influence of single navigator data on the positioning accuracy.

In some embodiments, the mobile phone may have a plurality of navigation chips, and at this time, the navigation abstract layer library may obtain navigation data of the plurality of navigation chips at the same time, and perform merging to calculate a distance, so as to obtain more accurate location information.

Referring to fig. 12, fig. 12 shows a scenario in which a mobile phone according to an embodiment of the present application has two navigation chips. The scenario may correspond to adding data of a navigation chip at S940 in fig. 9, or to adding data of a navigation chip at S1140 in fig. 11. As shown in fig. 12. The mobile phone comprises two mobile phone navigation chips, each of which can correspond to one sub-navigation abstraction layer library, for example, mobile phone navigation chip 1 corresponds to libgps.so1 (hal), and mobile phone navigation chip 2 corresponds to libgps.so2 (hal). The data obtained by the two sub navigation abstraction layer libraries are uniformly transmitted to a father navigation abstraction layer library (libGPS. Common. So (hal)), and the father navigation abstraction layer library calculates the distance from the mobile phone or the navigator to the satellite by combining the two sub navigation abstraction layer libraries and NMEA data obtained from a Bluetooth navigation agent (hal) (navigator) to obtain the current position of the mobile phone or the navigator. The procedure of NMEA data obtained from the bluetooth navigation agent (hal), i.e. from the navigator, may refer to the acquisition procedure of fig. 8-11, and will not be described herein.

According to the positioning method based on Bluetooth transmission, the NMEA data relayed by indiscriminate use and the NMEA data reported by the GPS chip of the electronic equipment are realized through the newly added Bluetooth navigation agent (hal) and the navigation abstract layer library (hal), so that the complexity of a data processing flow is simplified, the user operation is simplified, and the positioning accuracy is improved. In addition, no program outside the additional system is needed to assist the navigation process, so that the space utilization rate and the electric quantity loss are saved, and the user experience is improved.
