Description

Bluetooth service query method and electronic equipment

Technical Field

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

Background

Currently, bluetooth services are identified by a Universally Unique Identifier (UUID). Wherein, the bluetooth service of different UUID identifications is different. Before using the bluetooth service provided by the peer bluetooth device, the electronic device, such as a mobile phone or a tablet computer, needs to query a bluetooth service UUID list (service UUID list) of the peer bluetooth device to determine which bluetooth services are supported by the peer bluetooth device. Specifically, the service UUID list of the peer bluetooth device includes at least one UUID, and each UUID in the at least one UUID is used to identify a bluetooth service supported by one peer bluetooth device.

Taking bluetooth headsets as an example, the service UUID list of bluetooth headsets includes UUID1 and UUID2. The UUID1 is used to identify an advanced audio distribution profile (A2 DP), and the UUID2 is used to identify a hands-free profile (HFP). The A2DP means that after the Bluetooth earphone is connected with the mobile phone through Bluetooth, the Bluetooth earphone can be used as a microphone and a receiver of the mobile phone to perform voice communication, and can also be used as a playing device of the mobile phone to play audio files on the mobile phone. HFP means that after the bluetooth headset is connected with a mobile phone through bluetooth, the user can control to answer, reject or hang up the incoming call on the mobile phone, or control to use the mobile phone to make a call.

In practical application, the mobile phone queries the service UUID list of the peer bluetooth device through an application program (e.g., a system application, a third party application, etc.). Specifically, as shown in fig. 1, an application program sends a request for querying a bluetooth service of an opposite-end bluetooth device to a bluetooth chip in a mobile phone, the bluetooth chip in the mobile phone receives the request for querying the bluetooth service of the opposite-end bluetooth device, and then sends a query command for the bluetooth service to the opposite-end bluetooth device, the bluetooth chip of the opposite-end bluetooth device obtains a service UUID list after receiving the query command, and returns the obtained service UUID list to the bluetooth chip in the mobile phone, and then the bluetooth chip in the mobile phone returns the received service UUID list from the opposite-end bluetooth device to the application program. Through the inquiry mode of the Bluetooth service, when a plurality of application programs of the Bluetooth service of the Bluetooth device at the opposite terminal need to be inquired on the mobile phone, the Bluetooth device at the opposite terminal may receive inquiry commands of the Bluetooth service from the plurality of application programs at the same time, so that the processing capacity of the Bluetooth chip of the opposite terminal is exceeded, and the connection between the mobile phone and the Bluetooth device at the opposite terminal is abnormal. In addition, for some third-party applications installed on the mobile phone, an inquiry command of the bluetooth service may be frequently sent to the bluetooth chip of the peer bluetooth device, so that the peer bluetooth device may also disconnect the bluetooth connection with the mobile phone due to self protection.

In summary, in the prior art, the method for directly issuing the inquiry command to the peer bluetooth device to inquire the bluetooth service easily causes the abnormality of the bluetooth connection, and reduces the user experience.

The electronic device 100 may support 1 or N SIM card interfaces, N being a positive integer greater than 1. The SIM card interface 152 may support a Nano SIM card, a Micro SIM card, a SIM card, or the like. Multiple cards can be inserted into the same SIM card interface 152 at the same time. The types of the plurality of cards may be the same or different. The SIM card interface 152 may also be compatible with different types of SIM cards. The SIM card interface 152 may also be compatible with an external memory card. The electronic device 100 interacts with the network through the SIM card to implement functions such as communication and data communication. In some embodiments, the electronic device 100 may also employ esims, namely: an embedded SIM card. The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100. For example, when only one SIM card can be inserted into the SIM card interface 152, the electronic device 100 can access a cellular network through the SIM card inserted into the SIM card interface 152. For another example, when the SIM card interface 152 is capable of inserting two SIM cards, the electronic device 100 can access a cellular network through the two SIM cards inserted in the SIM card interface 152 respectively.

The USB interface 170 is an interface conforming to the USB standard specification. For example, the USB interface 170 may include a Mini USB interface, a Micro USB interface, a USB Type C interface, and the like. The USB interface 170 may be used to connect a charger to charge the electronic device 100, to transmit data between the electronic device 100 and a peripheral device, or to connect an earphone to play audio through the earphone.

The charge management module 180 is configured to receive a charging input from a charger. The charger may be a wireless charger or a wired charger. In some wired charging embodiments, the charging management module 180 may receive charging input from a wired charger via the USB interface 170. In some wireless charging embodiments, the charging management module 180 may receive a wireless charging input through a wireless charging coil of the electronic device 100. The charging management module 180 may also supply power to the electronic device 100 through the power management module 181 while charging the battery 182.

The power management module 181 is used to connect the battery 182, the charging management module 180 and the processor 110.

In other embodiments, the power management module 181 and the charging management module 180 may be disposed in the same device.

It should be understood that the hardware configuration of the electronic device 100 shown in fig. 2 is only one example. The electronic devices of embodiments of the application may have more or fewer components than shown in the figures, may combine two or more components, or may have different configurations of components. The various components shown in the figures may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and/or application specific integrated circuits.

The following describes an embodiment of the present application in detail, taking the hardware configuration of the electronic device 100 shown in fig. 2 as an example.

It should be understood that the electronic device 100 in the embodiment of the present application generally provides various functions for the user through the application program. By way of example, the application program may be a system application (also referred to as a native application) or may be a third party application. Such as drawing, presentation, word processing, gaming, telephony, video player, music player, email, instant messaging, photo management, camera, browser, calendar, clock, payment, application marketplace, desktop, and health management applications. For example, the electronic device 100 in the embodiment of the present application may run a plurality of applications simultaneously.

Illustratively, fig. 3a is a schematic diagram of a graphical user interface according to an embodiment of the present application. The graphical user interface is referred to below simply as the user interface. The electronic device 100 displays a user interface through the display screen 151. Specifically, the user interface may be a main interface, a negative screen, or a user interface of an application. For example, the main interface may be the user interface 300 shown in FIG. 3 a. As shown, the user interface 300 may include a status bar 301, a time and weather Widget302, a concealable navigation bar 303, and icons for multiple applications, such as a settings icon 304. The status bar 301 may include the name of the operator (china mobile), the mobile network (e.g. 4G), the time and the remaining power. In some other embodiments of the present application, the status bar 301 may include the name of the operator (china mobile), the signal strength of the mobile network, the time and the remaining power. In other embodiments of the present application, the status bar 301 may further include one or more of a bluetooth icon, a WiFi icon, a screen lock icon, an add-on icon, and the like. For example, taking the bluetooth icon as an example, in the embodiment of the present application, the electronic device 100 may display the bluetooth icon in the status bar 301 after the bluetooth function is turned on, and may not display the bluetooth icon in the status bar 301 after the bluetooth function is turned off. The navigation bar 303 may include a back button (back button), a home screen button (home button), and a history task view button (menu button). It will also be appreciated that in other embodiments, the user interface 300 may also include a Dock bar. Icons of common applications, such as a telephone icon, a short message icon, a mail icon, a weather icon and the like, can be included in the Dock bar. It should be understood that the user can set icons of common applications in the Dock bar according to the requirement of the user.

In other embodiments, as shown in fig. 3a, electronic device 100 may also include a home screen key 305. The home screen key 305 may be a physical key or a virtual key. The home screen key 305 is used to return a user interface of an application or a user interface such as a minus screen displayed on the display screen 151 to the home interface according to a user operation, so that the user can conveniently view the home interface at any time and operate a control (e.g., an icon) on the home interface. The operation may be specifically the user pressing the home screen key 305. In some other embodiments of the present application, the home screen key 305 may further integrate the fingerprint sensor 160B, so that the user can perform fingerprint collection by the electronic device 100 when pressing the home screen key 305, and then confirm the user identity. In other embodiments, electronic device 100 may not include home screen key 305.

For example, when the user interface 300 is displayed on the display screen 151, the electronic apparatus 100 may display a system setting interface on the display screen 151 in response to a touch operation of the user on the setting icon 304. The system setting interface includes various function buttons for performing corresponding settings on the electronic device 100. For example, the system setup interface may be a user interface 310 as shown in fig. 3b, including a bluetooth button 311. In addition, the user interface 310 may further include function buttons for account login, cloud backup opening, screen locking, and the like. The electronic apparatus 100 may display a bluetooth setting interface on the display screen 151 in response to the user's operation of the bluetooth button 311. Wherein, the bluetooth setting interface is used for opening or closing the bluetooth function. For example, when the electronic device 100 is not turned on, the bluetooth setup interface may be the user interface 320 shown in fig. 3 c. As shown in fig. 3c, the user interface 320 includes a bluetooth button 321, and the bluetooth button 321 is in an OFF state. When the bluetooth button 321 is in the off state, the bluetooth function of the electronic device 100 is not turned on. The electronic apparatus 100 may turn ON the bluetooth function by turning ON (ON) the bluetooth button 321 in response to the user's operation of the bluetooth button 321. Furthermore, in other embodiments, the electronic device 100 may further display a shortcut setting user interface on the display screen 151 in response to a pull-down operation or a pull-up operation of a user when the display screen 151 displays a certain user interface (e.g., the user interface 300) after being locked or unlocked. Specifically, the shortcut setting interface includes a shortcut button for setting various functions, such as a shortcut button for turning on or off a bluetooth function. For example, the quick setup user interface may be the user interface 400 shown in FIG. 4. A bluetooth button 401 is included on the user interface 400. The electronic device 100 may turn the bluetooth function on or off in response to the user's operation of the bluetooth button 401. For example, the electronic apparatus 100 may turn on the bluetooth function in response to the user's operation of the bluetooth button 401 when the bluetooth function is not turned on. For another example, when the bluetooth function is turned on, the electronic device 100 may turn off the bluetooth function in response to the user's operation of the bluetooth button 401. In addition, in some embodiments, the user interface 400 may further include functional buttons such as WiFi, personal hotspot, flight mode, do-not-disturb, ring, move data, brightness adjustment, and so on, so that the user may quickly set the corresponding function. It should be noted that, in the embodiment of the present application, the electronic device 100 may also turn on or turn off the bluetooth function by other manners, such as a voice command, a shortcut gesture operation, and the like, which is not limited thereto.

It should be understood that, after the bluetooth function is turned on, the electronic device 100 may be scanned and found by an electronic device that has the bluetooth function nearby as a slave (slave), or may be scanned and found by an electronic device that has the bluetooth function nearby as a master (master). For example, as shown in fig. 5, if the electronic device 100 and the electronic device 200 both have bluetooth functions turned on and the electronic device 200 is located near the electronic device 100, the electronic device 100 and the electronic device 200 may scan each other for discovery, so that a bluetooth connection may be established.

A process of establishing a bluetooth connection between the electronic device 100 and the electronic device 200 will be described below by taking the electronic device 100 as a master device and the electronic device 200 as a slave device as an example.

After the bluetooth function is turned on, the electronic device 100 performs a device scanning process to find nearby electronic devices with the bluetooth function turned on. In addition, after the electronic device 100 has the bluetooth function turned on, the user interface 320 displayed on the display screen 151 may include a prompt, a list of available devices, etc. that the electronic device 100 is currently discoverable by nearby bluetooth devices. Wherein, the available device list includes at least one device identifier, each device identifier is used to identify an electronic device which is scanned and found by the electronic device 100 and has bluetooth function turned on nearby, thereby being helpful for prompting the user. In some embodiments, the device identification may include one or more of a device name, a device type, or a Media Access Control (MAC) address, among others. For example, device types may include cell phones, bluetooth headsets, bluetooth mice, tablets, laptops, desktops, display screens, bluetooth keyboards, bluetooth printers, bluetooth facsimile machines, and so forth. The device type may be presented to the user in the list of available devices 322 in graphical or textual form, or the like. In addition, it should be noted that, in the embodiment of the present application, the name of the device may be a model of the device, or may be set by a user, which is not limited herein. For example, if the electronic device 100 scans and discovers an electronic device a, an electronic device 200 and an electronic device b, where the identifier of the electronic device a is Sql, the identifier of the electronic device 200 is 200, and the identifier of the electronic device b is Watch, the user interface 320 displayed by the electronic device 100 may include Sql, 200 and Watch as shown in fig. 3d, and the available device list 322 includes Sql, 200 and Watch. Wherein the available devices list 322 can be updated according to the electronic devices scanned and discovered by the electronic device 100.

In some embodiments, electronic device 100 may perform the device scanning process in the following manner:

the method I comprises the following steps: after the electronic device 100 as a master device starts the bluetooth function, it broadcasts a scan request, and an electronic device (e.g., the electronic device 200) with a nearby bluetooth function started may receive the scan request and send a scan response to the electronic device 100 as a slave device, so that the electronic device 100 discovers the electronic device with a nearby bluetooth function started.

The second method comprises the following steps: the electronic apparatus 100 as a master may receive a broadcast message of a nearby electronic apparatus (slave) having a bluetooth function activated after the bluetooth function is activated, without transmitting a scan request. The nearby electronic equipment with the Bluetooth function can periodically broadcast messages, and scanning and discovering of other electronic equipment with the Bluetooth function are facilitated. For example, the electronic device 100 receives a broadcast message of the electronic device 200 after turning on the bluetooth function, and thereby scans for the electronic device 200.

It should be noted that, after the electronic device 200 is found by scanning, the electronic device 100 establishes a physical link with the electronic device 200.

In this embodiment of the application, after the electronic device 100 scans and discovers the electronic device 200, a device pairing process is executed to pair with the electronic device 200. Specifically, the electronic device 100 may send a pairing request to the electronic device 200 after scanning and discovering the electronic device 200, and after receiving the pairing request of the electronic device 100, the electronic device 200 performs device authentication on the electronic device 100, and after the device authentication is passed, sends a pairing success response to the electronic device 100, so that the electronic device 100 establishes a logical link control and adaptation protocol (L2 CAP) channel with the electronic device 200. For example, if the electronic device 100 has not established a bluetooth connection with the electronic device 200, the pairing request may be sent to the electronic device 200 in response to the user selecting the identification of the electronic device 200 from the list of available devices. For another example, if the electronic device 100 establishes a bluetooth connection with the electronic device 200, the pairing request may be automatically sent to the electronic device 200 after the electronic device 200 is found by scanning. In addition, in the embodiment of the present application, the electronic device 100 may be triggered to send the pairing request to the electronic device 200 by other means, which is not limited to this.

It should be noted that, in this embodiment of the application, the electronic device 100 may stop the device scanning process in response to an operation of triggering to send a pairing request to the electronic device 200, or may continuously execute the device scanning process after the bluetooth function is turned on by the electronic device 100 until the device scanning process is not executed any more after the bluetooth function is turned off by the electronic device 100.

It should be noted that, in this embodiment of the application, after the electronic device 100 and the electronic device 200 are paired, it is also necessary to query the bluetooth service supported by the electronic device 200, so that the electronic device 100 and the electronic device 200 can complete the establishment of the bluetooth connection. It should be understood that the bluetooth services supported by different types of electronic devices in the embodiment of the present application may be the same or different. For example, for a bluetooth headset, the supported bluetooth services may include A2DP, HFP, and audio/video remote control profile (AVRCP), a headset application model (HSP), and the like.

In some embodiments, the electronic device 100 performs Service Discovery Protocol (SDP) interaction with the electronic device 200, so that the electronic device 100 may directly send an inquiry command of a bluetooth service to a bluetooth chip of the electronic device 200 through its own bluetooth chip to obtain a service UUID list of the electronic device 200. In view of the above, the embodiment of the present application provides an inquiry method of a bluetooth service, which can enable an application installed in the electronic device 100 to inquire about bluetooth services supported by a certain electronic device from pre-stored bluetooth service information supported by the electronic device in the electronic device 100 when an application requests to inquire about bluetooth services supported by the certain electronic device by using information of the bluetooth services supported by the electronic device pre-stored in the electronic device 100, thereby helping to reduce the number of times of directly inquiring about bluetooth services from an opposite-end electronic device, and also helping to improve the efficiency of bluetooth service inquiry to a certain extent.

For example, as shown in fig. 6, a method for pre-storing information of a bluetooth service of an electronic device according to an embodiment of the present application includes the following steps.

Step 601, after the electronic device 100 starts the bluetooth function, receiving at least one scanning result, where each scanning result is sent by an electronic device that starts the bluetooth function near the electronic device 100, and the scanning result includes information of the bluetooth service supported by the electronic device. Illustratively, the information of the bluetooth service supported by the electronic device includes a device identification, and at least one UUID. Specifically, the device identifier is information for identifying the electronic device, such as one or more of a device type, a device name, a Media Access Control (MAC) address, and the like.

Taking the scan result sent by the electronic device 200 received by the electronic device 100 as an example, the scan result sent by the electronic device 200 includes bluetooth service information supported by the electronic device 200, such as an identifier of the electronic device 200 and at least one UUID supported by the electronic device 200. It should be understood that when the electronic device 100 receives the scanning result sent by the electronic device 200, the electronic device 100 scans to find the electronic device 200, and the identification of the electronic device 200 may be added to the list of available devices for presentation to the user.

It should be noted that, in the embodiment of the present application, the scanning result may be a message that is already in the device scanning process, for example, a scanning response, a broadcast message, and the like. For example, the implementation form of the scanning result may be different for different electronic devices. For example, for a classic bluetooth (BR/EDR) device, the scan Result may be an Extended requirement Result (Extended Inquiry Result), and for a Bluetooth Low Energy (BLE) device, the scan Result may be a broadcast packet. In addition, the scan result may also be a newly defined message.

Take the structure of the electronic device 100 shown in fig. 2 as an example. Specifically, the processor 110 (e.g., an application processor) detects that the bluetooth function is turned on, and sends a device scan command to the wireless communication module 132 (e.g., a bluetooth chip), and after receiving the device scan command, the wireless communication module 132 receives a scan result sent from at least one electronic device nearby. For example, the wireless communication module 132 may broadcast a scan request after receiving the device scan command. Some of the at least one electronic device in the vicinity may transmit the scan result to the wireless communication module 132 in response to receiving the scan request. After the Bluetooth function is started, part of electronic equipment in at least one piece of nearby electronic equipment can directly broadcast the scanning result without receiving a scanning request. In some embodiments, at least one electronic device in the vicinity may periodically broadcast the scan results after bluetooth functionality is turned on. The period of broadcasting the scanning result can be set according to actual conditions. Thereby facilitating scanning discovery by other bluetooth enabled electronic devices.

In step 602, the electronic device 100 obtains and stores information of the bluetooth service supported by at least one electronic device from at least one scan result. The information of the bluetooth service supported by the at least one electronic device may be stored in a form of a database, for example, the information of the bluetooth service supported by the at least one electronic device is stored as a database uuid.

Take the structure of the electronic device 100 shown in fig. 2 as an example. Specifically, after receiving the at least one scanning result, the wireless communication module 132 obtains information of the bluetooth service supported by the at least one electronic device from the at least one scanning result, and stores the information of the bluetooth service supported by the at least one electronic device in a corresponding storage form in a corresponding memory. For example, the wireless communication module 132 may store information of a bluetooth service supported by at least one electronic device in one or more of the internal memory 121, an external memory connected to the external memory interface 122, a memory provided in a functional module such as the processor 110 or the wireless communication module 132, and the like.

For example, the electronic device 100 receives a scan result 1, a scan result 2, and a scan result 3, where the scan result 1 includes information of bluetooth services supported by the electronic device a, such as device identifiers a, UUID1, and UUID2, the scan result 2 includes information of bluetooth services supported by the electronic device 200, such as device identifiers b and UUID3, and the scan result 3 includes information of bluetooth services supported by the electronic device c, such as device identifiers c and UUID2. If the UUID1, the UUID2, and the UUID3 are respectively used to indicate a bluetooth service, the information of the bluetooth service supported by at least one electronic device, which is obtained and stored by the electronic device 100 from the scanning result 1, the scanning result 2, and the scanning result 3, may be as shown in table 1.

TABLE 1

Taking table 1 as an example, when the electronic device 100 receives the scan result sent by the electronic device 200 again, the electronic device may update the information of the bluetooth services supported by the electronic device 200 in the stored information of the bluetooth services supported by at least one electronic device according to the scan result sent by the electronic device 200 received again. For example, if the scan result sent by the electronic device 200 and received again by the electronic device 100 includes the device identifier b, the UUID1, the UUID3, and the UUID4, the information of the bluetooth service supported by the electronic device as shown in table 1 may be updated by adding the UUID1 and the UUID4 to the service UUID list 2. The updated information of the bluetooth service supported by the electronic device may be as shown in table 2.

TABLE 2

For another example, after saving the information of the bluetooth service supported by the electronic device shown in table 1, the electronic device 100 may update the saved information of the bluetooth service supported by the electronic device according to the scan result sent by the electronic device d when receiving the scan result sent by the electronic device d. For example, if the scan result sent by the electronic device d includes the device identifier 4, the UUID1, and the UUID4, the information of the bluetooth service supported by the electronic device d may be added to the information of the bluetooth service supported by the electronic device as shown in table 1. The updated information of the bluetooth service supported by the electronic device may be as shown in table 3.

TABLE 3

Step 603, the electronic device 100 sends a pairing request to one or more electronic devices of the at least one scanned and discovered electronic device, where a manner in which the electronic device 100 triggers sending of the pairing request to one or more electronic devices of the at least one scanned and discovered electronic device may refer to a manner in which the electronic device 100 triggers sending of the pairing request to the electronic device 200 in the foregoing embodiment, which is not described herein again.

Step 604, after receiving the pairing request sent by the electronic device 100, one or more electronic devices of the at least one electronic device found by scanning authenticate the electronic device 100, and after the authentication passes, send a pairing success response to the electronic device 100. And the pairing success response comprises information of the Bluetooth service supported by the electronic equipment. For example, the information of the bluetooth service supported by the electronic device includes a device identification, and at least one UUID.

Step 605, after receiving the at least one pairing success response, the electronic device 100 acquires and stores information of the bluetooth service supported by the at least one electronic device from the at least one pairing success response.

The configuration of the electronic apparatus 100 shown in fig. 2 is taken as an example, and the electronic apparatus 100 is paired with the electronic apparatus 200. Specifically, the processor 110 sends a pairing notification with the electronic device 200 to the wireless communication module 132 in response to an operation of triggering pairing with the electronic device 200, and the wireless communication module 132 sends a pairing request to the electronic device 200 after receiving the pairing notification with the electronic device 200. After receiving the pairing request, the electronic device 200 authenticates the electronic device 100, and after the authentication is passed, sends a pairing success response to the electronic device 100. The pairing success response includes information of at least one bluetooth service supported by the electronic device 200. For example, the pairing success response includes the identification of the electronic device 200 and at least one UUID. Each UUID is used to identify a bluetooth service supported by the electronic device 200. After receiving the pairing success response, the wireless communication module 132 obtains information of at least one bluetooth service supported by the electronic device 200 from the pairing success response, and stores the information in a corresponding storage form into a corresponding memory. For example, the electronic apparatus 100 may store the information of the at least one bluetooth service supported by the electronic apparatus 200 acquired from the pairing success response in the form of a configuration file (e.g., bt _ config.conf) in one or more of the internal memory 121, the external memory connected to the external memory interface 122, the processor 110, or a memory provided in the wireless communication module 132.

It should be understood that, after the electronic device 100 is successfully paired with the electronic device 200 for the first time, the information of the bluetooth service supported by the electronic device 200 is stored in the electronic device 100, and when the electronic device 200 is paired with the electronic device 100 again, after receiving a pairing success response sent by the electronic device 200, the information of the bluetooth service supported by the electronic device 200 may not be obtained from the pairing success response any more, the information of the bluetooth service supported by the electronic device 200 may also be continuously obtained from the pairing success response, and the stored information of the bluetooth service supported by the electronic device 200 may be updated according to the obtained information of the bluetooth service supported by the electronic device 200.

For example, after the electronic device 100 and the electronic device 200 are successfully paired for the first time, the stored information of the bluetooth service supported by the electronic device 200 is shown in table 4. The device identifier b is an identifier of the electronic device 200, and the UUID1, the UUID2, and the UUID3 are respectively used for indicating a bluetooth service supported by the electronic device 200.

TABLE 4

When the electronic device 100 is paired with the electronic device 200 again, a pairing success response sent by the electronic device 200 is received, and if the pairing success response still includes the device identifier b, the UUID1, the UUID2, and the UUID3, the stored information of the bluetooth service supported by the electronic device 200 is not updated. If the pairing success response further includes the device identifier b, the UUID1, the UUID2, and the UUID4, the stored information of the bluetooth service supported by the electronic device 200 is updated, specifically, the UUID4 is added to the stored information of the bluetooth service supported by the electronic device 200, and the updated information of the bluetooth service supported by the electronic device 200 may be as shown in table 5.

TABLE 5

It should be noted that the method for pre-storing the information of the bluetooth service of the electronic device shown in fig. 6 is only an example, and in this embodiment, the electronic device 100 may further only store the information of the bluetooth service supported by the electronic device included in the scanning result, and does not store the information of the bluetooth service supported by the electronic device included in the pairing success response; alternatively, the electronic device 100 may not store the information of the bluetooth service supported by the electronic device included in the scan result, and may only store the information of the bluetooth service supported by the electronic device included in the pairing success response.

Further, in the embodiment of the present application, when saving both the information of the bluetooth service supported by the electronic device included in the scan result and the information of the bluetooth service supported by the electronic device included in the pairing success response, the electronic device 100 may save together the information of the bluetooth service supported by the electronic device included in the scan result and the information of the bluetooth service supported by the electronic device included in the pairing success response. It should be understood that, when the information of the bluetooth service supported by the electronic device included in the scan result and the information of the bluetooth service supported by the electronic device included in the pairing success response are stored together, the information of the bluetooth service supported by the electronic device included in the scan result and the information of the bluetooth service supported by the electronic device included in the pairing success response are stored in the same location and in the same form.

Taking the electronic device 200 as an example, the electronic device 100 receives a scanning result sent by the electronic device 200, where the scanning result includes the device identifier b, the UUID1, and the UUID2. The electronic apparatus 100 stores information of the bluetooth service supported by the electronic apparatus 200 according to the scanning result as shown in table 6.

TABLE 6

For example, the electronic device 100 receives a pairing success response of the electronic device 200, where the pairing success response includes the device identifier b, the UUID1, the UUID2, the UUID3, and the UUID4, and then the electronic device 100 updates the information of the bluetooth service supported by the electronic device 200 shown in table 6 according to the pairing success response of the electronic device 200, and the updated information of the bluetooth service supported by the electronic device 200 is shown in table 7.

TABLE 7

In other embodiments of the present application, when the electronic device 100 stores both the information of the bluetooth service supported by the electronic device included in the scan result and the information of the bluetooth service supported by the electronic device included in the pairing success response, the electronic device 100 may separately store the information of the bluetooth service supported by the electronic device included in the scan result and the information of the bluetooth service supported by the electronic device included in the pairing success response. For example, taking the electronic device 200 as an example, the electronic device 100 receives a scanning result sent by the electronic device 200, where the scanning result includes the device identifier b, the UUID1, and the UUID2. The electronic device 100 stores information of the bluetooth service supported by the electronic device 200 according to the scan result as shown in table 8.

TABLE 8

For example, if the electronic device 100 receives a pairing success response of the electronic device 200, and the pairing success response includes the device identifier b, the UUID1, the UUID2, the UUID3, and the UUID4, the electronic device 100 stores information of the bluetooth service supported by the electronic device 200 according to the pairing success response, as shown in table 9.

TABLE 9

For example, the information of the bluetooth service supported by the electronic device 200 shown in table 8 may be stored in the memory 1 in a first storage form, and the information of the bluetooth service supported by the electronic device 200 shown in table 9 may be stored in the memory 2 in a second storage form. The first storage form and the second storage form may be different, for example, the first storage form may be a database, the second storage form may be a configuration file, and the first storage form and the second storage form may also be the same. The memory 1 and the memory 2 may be the same or different.

In some other embodiments, the information of the bluetooth service supported by the electronic device, which is stored in the electronic device 100 in advance, may also be stored before the electronic device 100 leaves the factory. For example, the information of the bluetooth service supported by the electronic device, which is pre-stored in the electronic device 100, may include a device type and at least one UUID corresponding to the device type. For example, information of the bluetooth service supported by the electronic device, which is stored in advance in the electronic device 100, may be as shown in table 10.

TABLE 10

Based on the method for storing the bluetooth service supported by the electronic device 100, an embodiment of the present application provides an inquiry method for the bluetooth service. For example, as shown in fig. 7, a flowchart of an inquiry method for a bluetooth service provided in an embodiment of the present application is illustrated. Comprises the following steps.

In step 701, the electronic device 100 detects that the first application requests to obtain the bluetooth service of the electronic device 200.

In step 702, the electronic device 100 queries the bluetooth service supported by the electronic device 200 from the pre-stored information of the bluetooth service supported by the electronic device according to the identifier of the electronic device 200.

It should be noted that, in some embodiments, the first application may be a system application (e.g., system settings, etc.), and may be a third-party application (e.g., weChat, youke video, etc.), which is not limited thereto. In other embodiments, the first application is a third party application. When the system application requests to acquire the bluetooth service of the electronic device 200, the electronic device 100 may acquire the bluetooth service in a manner of querying the bluetooth service in the prior art.

Take the structure of the electronic device 100 shown in fig. 2 as an example. Specifically, when the processor 110 (e.g., an application processor) detects that the first application requests to acquire the bluetooth service of the electronic device 200, the processor may call an interface of the first application and send a request for acquiring the bluetooth service of the electronic device 200 to the wireless communication module 132 (e.g., a bluetooth chip). The wireless communication module 132 receives a request for acquiring the bluetooth service of the electronic device 200 from the processor 110 through the interface of the first application, acquires the bluetooth service of the electronic device 200 from the information of the bluetooth service supported by the electronic device, which is pre-stored in the corresponding memory, according to the identifier of the electronic device 200, and returns the acquired bluetooth service of the electronic device 200 to the processor 110 through the interface of the first application.

However, since the electronic device 200 and the electronic device 100 may be paired, paired or unpaired when the first application requests to query the bluetooth service of the electronic device 200, in some specific embodiments, the electronic device 100 may detect the pairing status of the electronic device 200 and the electronic device 100 after detecting that the first application requests to acquire the bluetooth service of the electronic device 200. When the electronic device 200 and the electronic device 100 are in the paired state, step 702 is executed, and when the electronic device 200 and the electronic device 100 are in the pairing state, step 702 may be executed after the electronic device 200 and the electronic device 100 are successfully paired. When the electronic device 200 is in an unpaired state with the electronic device 100, the step of querying the bluetooth service supported by the electronic device 200 may not be performed any more, thereby contributing to reduction of signaling processing of the electronic device 100.

For example, after receiving the request for acquiring the bluetooth service of the electronic device 200 sent by the processor 110 through the interface of the first application, the wireless communication module 132 may first detect a pairing status of the electronic device 100 and the electronic device 200, and then determine whether to perform the step of querying the bluetooth service supported by the electronic device 200 according to the pairing status of the electronic device 100 and the electronic device 200.

In other embodiments, the electronic apparatus 100 may transmit an inquiry command of the bluetooth service to the electronic apparatus 200 when the bluetooth service of the electronic apparatus 200 is not acquired from the information of the bluetooth service supported by the electronic apparatus previously stored in the corresponding memory. Thereby helping to increase the likelihood of success of the electronic device 100 in acquiring bluetooth services supported by the electronic device 200. It should be noted that the inquiry command of the bluetooth service sent by the electronic apparatus 100 to the electronic apparatus 200 may be an SDP command.

For example, when the bluetooth service of the electronic device 200 is not acquired from the information of the bluetooth service supported by the electronic device, which is pre-stored in the corresponding memory, the wireless communication module 132 may directly send an inquiry command of the bluetooth service to the electronic device 200, or may send a notification of an inquiry failure to the processor 110 through the interface of the first application, and the processor 110 determines whether to send the inquiry command of the bluetooth service to the electronic device 200 through the wireless communication module 132. Specifically, the policy for the processor 110 to determine whether the wireless communication module 132 sends the bluetooth query command to the electronic device 200 according to the embodiment of the present application may be set according to actual needs.

In particular, in the case that the electronic device 100 adopts the method shown in fig. 6 to store the information of the bluetooth service supported by the electronic device in advance, and the scan result and the information of the bluetooth service supported by the electronic device included in the pairing success response are stored separately, the electronic device 100 may also query the bluetooth service of the electronic device 200 in other ways when specifically implementing.

In the following, the detailed description will be given of the case where the electronic device 100 stores information of the bluetooth service supported by at least one electronic device as uuid.db in step 602, and the electronic device 100 stores information of the bluetooth service supported by the electronic device as bt _ config.conf file in step 605.

In some embodiments, the electronic apparatus 100 detects that the first application requests acquisition of the bluetooth service of the electronic apparatus 200, and determines whether to query the bluetooth service supported by the electronic apparatus 200 from uuid.d or bt _ config.conf according to the pairing state of the electronic apparatus 200 and the electronic apparatus 100.

The first application program may be a system application or a third-party application, which is not limited to this. In addition, in this embodiment of the application, when it is detected that the first application program requests to acquire the bluetooth service of the electronic device 200, if the first application program is a third-party application, the electronic device 100 may determine whether to query the bluetooth service supported by the electronic device 200 from uuid.d or bt _ config.conf according to the pairing state of the electronic device 200 and the electronic device 100. In some embodiments, when the electronic device 100 detects that the first application requests to acquire the bluetooth service of the electronic device 200, if the first application is a system application, the bluetooth service supported by the electronic device 200 may be directly queried from bt _ config.conf.

The following describes in detail whether the electronic apparatus 100 determines to inquire about the bluetooth service supported by the electronic apparatus 200 from uuid.d or bt _ config.conf according to the pairing state in which the electronic apparatus 200 and the electronic apparatus 100 are in.

For example, when the electronic apparatus 200 and the electronic apparatus 100 are in the paired state, the electronic apparatus 100 may query the bluetooth service supported by the electronic apparatus 200 from uuid.db and query the bluetooth service supported by the electronic apparatus 200 from bt _ config.conf, and obtain the bluetooth service supported by the electronic apparatus 200 by taking the bluetooth service supported by the electronic apparatus 200 respectively queried from uuid.db and the bluetooth service supported by the electronic apparatus 200 from bt _ config.conf.

Take the hardware structure of the electronic device 100 shown in fig. 2 as an example. Specifically, when the electronic device 200 and the electronic device 100 are in the paired state, the wireless communication module 132 may query the bluetooth service supported by the electronic device 200 from uuid.db and query the bluetooth service supported by the electronic device 200 from bt _ config.conf, and merge the bluetooth service supported by the electronic device 200 respectively queried from uuid.db and the bluetooth service supported by the electronic device 200 from bt _ config.conf, and then return the merged bluetooth service supported by the electronic device 200 to the processor 110. For example, the wireless communication module 132 may return the collected bluetooth services supported by the electronic device 200 to the processor 110 through an interface of the first application program, or the wireless communication module 132 may broadcast the collected bluetooth services supported by the electronic device 200 through an event, and the processor 110 calls the interface of the first application program to monitor the event broadcast to receive the bluetooth services supported by the electronic device 200 after collection.

For another example, the electronic device 100 may query the bluetooth service supported by the electronic device 200 from uuid.db when the electronic device 200 is in an unpaired state with the electronic device 100.

Take the hardware structure of the electronic device 100 shown in fig. 2 as an example. Specifically, the wireless communication module 132 may query the bluetooth service supported by the electronic device 200 from uuid.db when the electronic device 200 is in the unpaired state with the electronic device 100, and then return the queried bluetooth service supported by the electronic device 200 to the processor 110 through the interface of the first application. In some embodiments, when the electronic device 200 is in the unpaired state with the electronic device 100, the bluetooth service supported by the electronic device 200 is not queried from the uuid.db, and then a notification of the failure to query is returned to the processor 110 through the interface of the first application.

For another example, the electronic apparatus 100 may query the bluetooth service supported by the electronic apparatus 200 from uuid.db when the electronic apparatus 200 and the electronic apparatus 100 are in the pairing state.

Take the hardware structure of the electronic device 100 shown in fig. 2 as an example. Specifically, the wireless communication module 132 may query the bluetooth service supported by the electronic device 200 from uuid.db when the electronic device 200 and the electronic device 100 are in the pairing state, and then return the queried bluetooth service supported by the electronic device 200 to the processor 110 through the interface of the first application. In other embodiments, the wireless communication module 132 returns to the processor 110 through the interface of the first application that the electronic device 200 and the electronic device 100 are in the pairing state when the electronic device 200 and the electronic device 100 are in the pairing state and the bluetooth service supported by the electronic device 200 is not queried from uuid. After receiving the pairing status of the electronic device 200 and the electronic device 100 through the interface of the first application program, the processor 110 determines that the pairing status is busy mode, and after the pairing between the electronic device 200 and the electronic device 100 is successful, the processor transmits a request for acquiring the bluetooth service of the electronic device 200 to the wireless communication module 132 through the interface of the first application program. In addition, after receiving the pairing status of the electronic device 200 and the electronic device 100 through the interface of the first application, the processor 110 determines that the pairing status is busy mode, and may send a notification to the wireless communication module 132 through the interface of the first application to wait for the electronic device 200 to be successfully paired with the electronic device 100 to inquire about the bluetooth service of the electronic device 200.
