Description

[0001] This application is a divisional application. The application number of the original application is 202010808831.7, and the filing date of the original application is August 12, 2020. The entire content of the original application is incorporated herein by reference. Technical Field

[0002] This application relates to the field of terminal technologies, and in particular, to a Bluetooth communication method, a wearable device, and a system. Background Art

[0003] With the development of wireless technologies, Bluetooth technology is widely used in wearable devices such as earphones and watches to enable Bluetooth calls using the wearable devices, thereby improving the convenience of calls. To implement the Bluetooth call function, a hands-free protocol (HFP) connection needs to be established in advance between the wearable device and the electronic device. Subsequently, when the electronic device receives a call service, based on the HFP connection, an extended synchronous connection oriented link (eSco) is established between the electronic device and the wearable device as an audio data transmission channel, so as to implement processing of the call service using the wearable device. After the call service ends, the electronic device disconnects the eSco with the wearable device, but maintains the HFP connection for processing the next call service.

[0004] When an HFP connection is established between the electronic device and the wearable device, if the electronic device needs to process a call service, it will default to invoking the wearable device that has established the HFP connection with it to process the audio data of the call service, such as receiving audio data or playing audio data. However, in some scenarios, when the call service is a short message voice chat or a video call in an instant messaging application, etc., it is not convenient for the user to operate using the wearable device (such as a smart watch, a smart bracelet, etc.). This is because, on the one hand, the user needs to manually operate the electronic device, such as selecting a contact, clicking on the unread "voice", or viewing the image of the other party, etc., and on the other hand, the user needs to use the wearable device to listen to the sound. Operating two devices simultaneously results in a poor user experience.

[0005] Based on the above scenario, a solution is proposed in the prior art. If an electronic device needs to handle a call service, it sends an eSco establishment request to the wearable device. The wearable device first establishes an eSco with the electronic device. After that, if the wearable device confirms that the current call service is a call service in an instant messaging application, it then disconnects the eSco. This enables the electronic device to use its own audio module to handle the call service, that is, to ensure that the user can complete the call service by operating one device. However, in this solution, there will be a certain delay during the process from establishing the eSco to disconnecting the eSco. For example, when the user needs to record a short voice message, after clicking to start recording, they need to wait until the electronic device can use the microphone to receive sound before they can start recording, resulting in a poor user experience. Summary of the Invention

[0006] The Bluetooth communication method, wearable device and system provided by this application can automatically disconnect the HFP connection when the electronic device meets the preset conditions. Furthermore, after the electronic device detects an operation of playing a voice message, it will not use the wearable device to play the voice message, causing unnecessary delay. And, after the electronic device receives an incoming call, it can re-establish the HFP connection to ensure that the electronic device can use the wearable device to answer the incoming call.

[0007] To achieve the above object, this application adopts the following technical solutions:

[0008] In a first aspect, this application provides a Bluetooth communication system. The Bluetooth communication system includes an electronic device and a wearable device, and a hands-free protocol HFP connection is established between the electronic device and the wearable device. Among them, the electronic device is used to automatically disconnect the HFP connection when the electronic device meets the preset conditions. The electronic device is also used to send a first notification to the wearable device after receiving an incoming call. The wearable device is used to establish an HFP connection with the electronic device according to the first notification. The electronic device is also used to send the first audio data of the incoming call to the wearable device and / or receive the second audio data of the incoming call sent by the wearable device after detecting the user's operation of answering the incoming call.

[0009] Optionally, the preset conditions include that the electronic device has not received an incoming call or has not detected an outgoing call operation. Among them, when the electronic device and the wearable device maintain the HFP connection, when the electronic device receives an incoming call or detects an outgoing call operation, it will send the corresponding call status to the wearable device. Then, the wearable device can determine whether the current electronic device needs to handle a call based on the HFP connection, and if not, it can disconnect the HFP connection.

[0010] In this way, by determining whether the electronic device meets the preset conditions, the automatic disconnection of the HFP connection can be achieved, which can effectively avoid the delay caused by the establishment and disconnection of the eSco link between the electronic device and the wearable device when the electronic device receives services such as voice messages, video calls, and audio calls while maintaining the HFP connection.

[0011] Moreover, when the electronic device receives an incoming call, it can notify the wearable device to achieve the reconstruction of the HFP connection. On the basis of ensuring that no unnecessary delay is caused, it can also ensure that the electronic device can use the wearable device to answer the call, improving the user experience.

[0012] Optionally, an application program for managing the wearable device, such as Application A, can be installed in the electronic device. Application A can be a third-party application program. Application A can monitor whether the electronic device receives an incoming call and send a first notification to the wearable device when an incoming call is received, so as to achieve the reconstruction of the HFP connection.

[0013] In a possible implementation manner, the electronic device is further configured to send a second notification to the wearable device after detecting the user's outgoing call operation. The wearable device is further configured to establish an HFP connection with the electronic device according to the second notification. After the call connection is established, the electronic device is further configured to send the third audio data of the outgoing call and / or receive the fourth audio data of the outgoing call sent by the wearable device.

[0014] That is to say, when the electronic device needs to process the first call service of an incoming call or an outgoing call, it can send a notification to the wearable device to reconstruct the HFP connection, ensuring that the wearable device can be used to play the audio of the call and collect the user's audio during the call.

[0015] In a possible implementation manner, the wearable device is further configured to disconnect the HFP connection with the electronic device after detecting an operation to end the call or receiving an instruction to end the call sent by the electronic device.

[0016] Among them, the user can hang up the phone by operating the wearable device after the call. Generally, after the phone is hung up, the electronic device no longer needs to process the first call service of an incoming call or an outgoing call at present. Then, if the wearable device determines that the current electronic device meets the preset conditions, the HFP connection is disconnected, thus avoiding unnecessary delay when the electronic device receives the second call service such as a voice message later. Or, the user can hang up the phone by operating the electronic device after the call. Then, after the electronic device detects the hang-up operation, it will send an instruction to the wearable device or the wearable device detects that the call has been disconnected, and then the HFP connection is disconnected.

[0017] In a possible implementation, the electronic device is further configured to play the first audio or record the second audio when detecting an operation of playing the first audio of the first application or recording the second audio using the first application.

[0018] Among them, the first application can be a third-party instant messaging application (for example, "WeChat" application, "QQ" application, video conferencing application, etc.). The voice message chat, audio call, video call, phone call voice, etc. in the first application can be described as the second call service. That is to say, generally, the call service can include the first call service and the second call service. The first call service includes services such as answering a call and making a call in a call application. The second call service includes call services in the first application.

[0019] Generally, the first application is installed in the electronic device. Correspondingly, a watch version of the first application is installed in a wearable device such as a smart watch. Of course, the first application may not be installed in the wearable device.

[0020] Then, when the electronic device detects an operation of playing the audio of the first application or recording audio, it will not detect a disconnected HFP connection and can directly use its own audio module, such as a speaker, a microphone, etc. to process the audio. For example, directly play a voice message or start recording a message based on the corresponding operation. Thus, it avoids the delay caused by the electronic device calling the wearable device to process the corresponding service after detecting the HFP connection.

[0021] In a possible implementation, the operation of playing the first audio includes any one of the following: an operation of playing the first voice message, an operation of answering a video call, and an operation of answering an audio call.

[0022] In a possible implementation, the operation of recording the second audio using the first application includes an operation of recording the second voice message using the first application or an operation of recording using the first application.

[0023] In a possible implementation, the electronic device is further configured to collect a third audio after a video call or an audio call connection is established.

[0024] Among them, in video call and audio call scenarios, the electronic device can use its own audio module to collect audio. There is no need to call the wearable device as an audio collection module.

After the call connection is established, the electronic device sends the third audio data of the outgoing call to the wearable device and / or receives the fourth audio data of the outgoing call sent by the wearable device.

[0078] The Bluetooth communication method, wearable device, and system provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0079] As used in the description of the present application, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally further include other steps or units not listed, or may optionally further include other steps or units inherent to these processes, methods, products, or devices.

[0080] It should be noted that in the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0081] In the description of the present application, unless otherwise specified, "a plurality of" means two or more. The "and / or" herein is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist simultaneously, and B exists alone.

[0082] As Figure 1 shown, it is a schematic diagram of an application scenario of a Bluetooth communication method provided by an embodiment of the present application. The system to which the Bluetooth communication method is applied includes a wearable device 100 and an electronic device 200.

[0083] Exemplarily, the wearable device 100 may be a smart watch, smart bracelet, wireless earphone, smart glasses, or smart helmet, etc. The electronic device 200 may be a mobile phone, tablet computer, laptop computer, ultra-mobile personal computer (UMPC), personal digital assistant (PDA), vehicle-mounted terminal, or other devices. The specific forms of the wearable device 100 and the electronic device 200 in the embodiments of the present application are not limited in any way.

[0084] The wearable device 100 can establish a wireless connection with the electronic device 200 through wireless communication technology. Among them, the wireless communication technology may include Bluetooth (BT), which can be traditional Bluetooth or low-power BLE Bluetooth, wireless local area networks (WLAN) (such as wireless fidelity (Wi-Fi) networks), Zigbee, frequency modulation (FM), near field communication (NFC), infrared technology (IR), or general 2.4G / 5G band wireless communication technology, etc.

[0085] In the embodiments of this application, the wireless communication technology is described by taking Bluetooth as an example. When the wearable device 100 and the electronic device 200 establish a Bluetooth connection, if the wearable device 100 supports the HFP service, an HFP connection can be established between the wearable device 100 and the electronic device 200. Subsequently, based on the HFP connection, the wearable device 100 serves as the Bluetooth device of the electronic device 200 to process the call services received by the electronic device 200. Among them, the call services include the first call service and the second call service. The first call service includes services such as answering calls and making calls in the call application. The second call service includes services such as short voice message chatting, audio calls, and video calls in third-party instant messaging applications (such as the "WeChat" application, the "QQ" application, video conferencing applications, etc.).

[0086] Generally, for users, if the call service is the first call service, the user only needs to use the wearable device 100 to process the first call service. If the call service is the second call service, the user needs to operate both the wearable device 100 and the electronic device 200 to complete the second call service. However, after the electronic device 200 receives a call service, it does not distinguish the call service type, that is, it does not distinguish whether the current call service is the first call service or the second call service. Instead, it will default to calling the wearable device 100 that has established an HFP connection with it to process the call service. Then, if the call service is the second call service, it will result in a poor user experience.

[0087] Based on this, two solutions have been proposed in the prior art.

[0088] Solution 1: In the case of an HFP connection, after the electronic device 200 receives a call service, it sends an eSco establishment request to the wearable device 100. The wearable device 100 agrees to the eSco establishment request and establishes an eSco with the electronic device 200. After that, the wearable device 100 determines whether the call service currently being processed by the electronic device 200 is the first call service. If not, it actively disconnects the eSco, enabling the electronic device 200 to switch back to its own speaker or microphone to process the second call service. However, after the eSco is established, the electronic device 200 will send audio data to the wearable device 100 based on the eSco or wait to receive audio data sent by the wearable device 200 until the eSco is disconnected. Then, during this process, if the user does not pay attention to the wearable device 100, the audio data sent by the electronic device 200 to the wearable device 100 will be lost; or, keep waiting until the eSco is disconnected and then the electronic device 200 receives the user's voice.

[0089] Solution 2: In the case of an HFP connection, after the electronic device 200 receives a call service, it sends an eSco establishment request to the wearable device 100. The wearable device 100 determines whether the call service currently being processed by the electronic device 200 is the first call service based on the eSco establishment request. If not, it refuses to establish the eSco, enabling the electronic device 200 to use its own speaker or microphone to process the second call service. However, the process of the wearable device 100 determining the current call service type takes time.

[0090] Therefore, in some embodiments of the present application, if the wearable device 100 determines that the electronic device 200 does not need to process the first call service, it actively disconnects the HFP connection with the electronic device 200. Then, when the electronic device 200 receives the second call service, it will not detect the disconnected HFP connection and will directly use the audio modules such as the speaker and microphone of the electronic device 200 to process the second call service. When the electronic device 200 receives the first call service, it notifies the wearable device 100 to re - establish the HFP connection. After that, based on the HFP connection, the wearable device 100 processes the first call service. In this way, it is ensured that the user can process the first call service and the second call service relatively simply. Moreover, during the process of the electronic device 200 processing the second call service, no unnecessary delay or call error will occur.

[0091] Figure 2 The structural schematic diagram of a wearable device 100 is shown. The wearable device 100 may include at least one processor 101, at least one memory 102, a wireless communication module 103, an audio module 104, at least one speaker 105, at least one microphone 106, and a power module 107, etc.

[0092] Among them, the memory 102 can be used to store application code, such as the application code for the wireless pairing connection between the wearable device 100 and the electronic device 200, so as to establish a wireless connection between the wearable device 100 and the electronic device 200; process the call service of the electronic device 200; and be used for charging the wearable device 100, etc.

[0093] The processor 101 can be used to execute the above application code and call relevant modules to implement the functions of the wearable device 100 in the embodiments of the present application. For example, implement functions such as wireless Bluetooth connection, audio playback, answering / making calls, etc. between the wearable device 100 and the electronic device 200. For another example, implement the wearable device 100 receiving a message sent by the electronic device 200 to determine whether the call service is a first call service, etc.

[0094] The processor 101 can include one or more processing units. Different processing units can be independent devices or integrated in one or more processors 101. Specifically, the processor 101 can be an integrated control chip or can be composed of a circuit including various active and / or passive components, and the circuit is configured to execute the functions belonging to the processor 101 described in the embodiments of the present application.

[0095] The wireless communication module 103 can be used to support data exchange of wireless communication between the wearable device 100 and its electronic device 200, including BT, WLAN (such as Wi-Fi), Zigbee, FM, NFC, IR, or general 2.4G / 5G wireless communication technologies, etc.

[0096] In some embodiments, the wireless communication module 103 can be a Bluetooth chip. The wearable device 100 can pair with the Bluetooth chip of the electronic device 200 through this Bluetooth chip and establish a wireless connection to implement wireless communication and service processing between the wearable device 100 and the electronic device 200 through this wireless connection. Generally, the Bluetooth chip can support basic rate (BR) / enhanced data rate (EDR) Bluetooth and Bluetooth low energy (BLE).

[0148] The software system of the electronic device 200 can adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservices architecture, or a cloud architecture. In the embodiments of the present invention, the Android system with a layered architecture is taken as an example to exemplarily illustrate the software structure of the electronic device 200.

[0149] Figure 3B It is the software structure block diagram of the electronic device 200 in the embodiments of the present invention.

[0150] The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom, namely the application layer, the application framework layer, the Android runtime and the system libraries, and the kernel layer.

[0151] The application layer can include a series of application packages.

[0152] Such asFigure 3B As shown, the application package may include applications such as camera, calendar, map, navigation, WLAN, music, short message, Bluetooth, call, video, etc.

[0153] In some embodiments, the application may further include Application A (such as applications for smart watches, sports health applications, etc.).

Application A can also support a message notification service to send notification messages to the wearable device 100. The notification message may include, for example, the call service type of the electronic device 200. Further, the wearable device 100 can learn about the call service type of the electronic device 200 based on the received notification message.

[0154] Optionally, the wearable device 100 can disconnect the HFP connection by receiving the notification message sent by Application A to avoid the delay of the second call service.

[0155] Optionally, the user can use Application A to set the wearable device 100, such as operations like switching modes and adding new devices. Among them, the signaling for this setting is usually a private Bluetooth protocol.

[0156] The application framework layer provides application programming interfaces (APIs) and programming frameworks for the applications in the application layer. The application framework layer includes some predefined functions.

[0157] As Figure 3B shown, the application framework layer may include a window manager, a content provider, a view system, a phone manager, a resource manager, a notification manager, an application manager, etc.

[0158] The window manager is used to manage window programs. The window manager can obtain the display screen size, determine whether there is a status bar, lock the screen, capture the screen, etc.

[0159] The content provider is used to store and obtain data, and make this data accessible to applications. The data may include videos, images, audio, dialed and answered calls, browsing history and bookmarks, phone book, etc.

[0160] The view system includes visual controls, such as controls for displaying text, controls for displaying pictures, etc. The view system can be used to build applications. The display interface can be composed of one or more views. For example, a display interface including a short message notification icon may include a view for displaying text and a view for displaying pictures.

[0161] The phone manager is used to provide the communication function of the electronic device 200. For example, the management of call states (including connection, disconnection, etc.).

[0162] In some embodiments, after the electronic device 200 receives the first call service, the phone manager will notify Application A by means of broadcast messages or the like.

[0163] The resource manager provides various resources for application programs, such as localized strings, icons, pictures, layout files, video files, and so on.

[0164] The notification manager enables application programs to display notification information in the status bar. It can be used to convey messages of the notification type, and can automatically disappear after a short stay without user interaction. For example, the notification manager is used to inform that the download is completed, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or a scroll bar text, such as the notification of a background running application program, and can also be a notification that appears on the screen in the form of a dialog window. For example, prompt text information in the status bar, emit a prompt tone, the electronic device vibrates, the indicator light flashes, etc.

[0165] The application manager can manage the life cycle of at least one application program, for example.

[0166] Android Runtime includes core libraries and a virtual machine. Android runtime is responsible for the scheduling and management of the Android system.

[0167] The core libraries include two parts: one part is the functional functions that need to be called by the Java language, and the other part is the core libraries of Android.

[0168] The application layer and the application framework layer run in the virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as the management of object life cycles, stack management, thread management, security and exception management, and garbage collection.

[0169] The system libraries can include multiple functional modules. For example: surface manager, Media Libraries, 3D graphics processing library (e.g., OpenGL ES), 2D graphics engine (e.g., SGL), etc.

[0170] The surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple application programs.

[0171] The media library supports the playback and recording of various common audio and video formats, as well as static image files, etc. The media library can support multiple audio and video coding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0172] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, synthesis, and layer processing, etc.

[0173] The 2D graphics engine is a graphics engine for 2D drawing.

[0174] The kernel layer is the layer between hardware and software. The kernel layer at least includes a display driver, a camera driver, an audio driver, and a sensor driver.

[0175] In the following embodiments, a smartwatch is used as the wearable device 100 and a mobile phone is used as the electronic device 200 for illustration.

[0176] As Figure 4 shown, it is a schematic flowchart of a Bluetooth communication method provided by an embodiment of the present application. The method may include S401 - S409.

[0177] S401. The mobile phone receives a first operation.

[0178] Among them, the first operation is used to instruct the mobile phone to establish a Bluetooth connection with the smartwatch. After the mobile phone detects the first operation, it starts the Bluetooth pairing process with the smartwatch. The first operation is, for example, an operation to trigger the start of Bluetooth pairing. For example, the first operation may include a series of operations such as turning on Bluetooth and selecting the wearable device detected during the process of the mobile phone establishing a connection with the smartwatch using Application A. Another example is that the first operation may include the operation of selecting the wearable device during the Bluetooth connection process. Another example is that when the smartwatch and the mobile phone have been paired before, the mobile phone can accept the operation on the smartwatch in the "My Devices" list in the Bluetooth "Settings" interface by the user for pairing.

[0179] Exemplarily, as Figure 5 shown in (a) therein, it is the main interface 501 displayed on the mobile phone. In response to the operation of the user clicking on the icon 51 of Application A (such as a sports and health APP), the mobile phone opens the sports and health APP and displays an interface 502 as shown in Figure 5 shown in (b) therein. In response to the operation of the user clicking on the device icon 52, a device management interface 503 as shown in Figure 5 shown in (c) therein is displayed. The user adds or deletes devices through the device management interface 503. In response to the operation of the user clicking on the add device control 53, the mobile phone displays as shown in Figure 5The interface 504 shown in (d) in []. The mobile phone detects an operation in response to a user clicking on the icon 54, determines the device type of the wearable device to be connected, and displays an interface as shown in Figure 5 (e) in []. The mobile phone displays an interface 505 as shown in Figure 5 (f) shown in [] in response to the user clicking on the icon 55. The mobile phone starts the pairing process with the smartwatch in response to the user clicking on the icon 56.

[0180] When the mobile phone starts the pairing process with the smartwatch and the Bluetooth of the mobile phone is not turned on, the mobile phone displays an interface 601 as shown in Figure 6 (a) in [] for receiving a first operation. In response to the user clicking on the OK icon 61, the mobile phone turns on the Bluetooth, searches for smartwatches that can be connected, and displays an interface 602 as shown in Figure 6 (b) in []. The icon 62 shown in the interface 602 is used to indicate that the Bluetooth of the mobile phone has been turned on. In response to the user clicking on the media access control (MAC) address of a certain smartwatch in the list 63, the mobile phone can establish a Bluetooth connection with the smartwatch selected by the user. That is to say, in the current scenario, the first operation includes the operation of clicking on the icon 61 and the operation of clicking on the MAC address of a certain smartwatch in the list 63.

[0181] When the mobile phone starts the pairing process with the smartwatch and the Bluetooth of the mobile phone is already turned on, the mobile phone directly displays an interface 602 as shown in Figure 6 (b) in []. Then, the first operation is the operation of clicking on the MAC address of a certain smartwatch in the list 63.

[0182] In some embodiments, in addition to the first operation received during the process of the mobile phone establishing a connection with the smartwatch using Application A as described above, the mobile phone can also turn on the Bluetooth and establish a Bluetooth connection with the smartwatch in various ways. For example, turn on the Bluetooth through a shortcut key method or through the Bluetooth settings method.

[0183] Exemplarily, the mobile phone displays a main interface 701 as shown in Figure 7 (a) in [], and displays an interface 702 as shown in Figure 7 (b) in [] in response to the user clicking on the settings icon 71. The mobile phone displays a Bluetooth settings interface 703 as shown in Figure 7 (c) in [] in response to the user clicking on the icon 72. Currently, the Bluetooth of the mobile phone is in the off state. The mobile phone turns on the Bluetooth and displays an interface as shown in Figure 7Interface 704 shown in (d) in FIG. 704. Icons 74 and 75 in interface 704 are used to indicate that Bluetooth is turned on. Afterwards, in response to the user clicking on the device name in list 76, the mobile phone directly establishes a Bluetooth connection with the corresponding device. Then, in the current scenario, the first operation is the operation of clicking on the device name in list 76.

[0184] In some embodiments, the mobile phone can also scan the pairing QR code on the smart watch to obtain a connection. Then the first operation may include an operation of scanning the pairing QR code, and the mobile phone reads the information contained in the pairing QR code to start the pairing process with the smart watch.

[0185] S402: The mobile phone establishes a Bluetooth connection and an HFP connection with the smart watch.

[0186] Optionally, after detecting the first operation, the mobile phone confirms the smart watch to be connected selected by the user, and sends a Bluetooth connection establishment request to the smart watch. After the mobile phone receives the response from the smart watch confirming the connection, it can establish a Bluetooth connection with the smart watch. In the above step S401, the mobile phone starts the Bluetooth pairing process with the smart watch through application A. After the mobile phone and the smart watch establish a Bluetooth connection, it indicates that the mobile phone has added the smart watch to the connected devices of application A. Then, the mobile phone can subsequently edit the smart watch through application A and send notification messages to the smart watch.

[0187] Among them, the HFP connection in the embodiment of the present application can be used to establish an eSco link to transmit voice data streams, and can also be used to establish an HFP service. The establishment of a Bluetooth connection in the embodiment of the present application can be a physical connection, such as an asynchronous connectionless (ACL) link.

[0188] For example, the mobile phone application A starts the pairing process and displays the following Figure 6 The interface 603 shown in (c) in FIG. 1 is used to prompt the user to confirm on the smart watch side. After the mobile phone receives the response sent by the smart watch to confirm the connection, it displays the following Figure 6 The device management interface 604 shown in (d) in FIG. 8 shows the smart watches that have been added.

[0189] Optionally, after detecting the operation of turning on Bluetooth, the mobile phone starts the hands-free protocol (HFP) connection establishment process with the smart watch based on the established Bluetooth connection. Figure 8 As shown, the process of establishing an HFP connection may include the following steps 1 to 8.

[0190] Step 1: The mobile phone sends an HFP service query request to the smart watch.

[0191] Step 2: The smartwatch sends the HFP service query result to the mobile phone.

[0192] Optionally, in the above Step 1 and Step 2, if the mobile phone needs to establish an HFP connection with the smartwatch, the mobile phone needs to send an HFP service query request to the smartwatch to confirm whether the smartwatch supports the HFP service. Herein, the HFP service means that the smartwatch can support the Bluetooth hands-free function and control mobile phone calls, such as answering, hanging up, rejecting, etc. After receiving the HFP service query request sent by the mobile phone, the smartwatch confirms whether it supports the HFP service.

[0193] If the smartwatch supports the HFP service, it sends the basic information (profile information) of the HFP service to the mobile phone. The profile information includes, for example, the protocol version number, the RFCOMM protocol channel number, etc.

[0194] If the smartwatch does not support the HFP service, the query result replied to the mobile phone is empty. After receiving this query result, the mobile phone confirms that the smartwatch does not support the HFP service and stops establishing the HFP connection.

[0195] In some embodiments, the mobile phone sends a query capability request to the smartwatch to query the services supported by the smartwatch. For example, a capability query request can be sent to the smartwatch through the service discover protocol (SDP). In response to this request, the smartwatch sends the capabilities it supports to the mobile phone, including but not limited to services such as HFP and the advanced audio distribution profile (A2DP).

[0196] Step 3: The mobile phone sends a communication link establishment request to the smartwatch.

[0197] Step 4: The smartwatch sends a communication link establishment response to the mobile phone.

[0198] Optionally, in the above Step 3 and Step 4, after receiving the profile information, the mobile phone confirms that the smartwatch supports the HFP service and then establishes a communication link with the smartwatch based on the profile information, such as a communication link based on the RFCOMM protocol.

[0199] The above steps 1 to 4 can also be described as the pairing process between the mobile phone and the smart watch. After the mobile phone and the smart watch are successfully paired, the smart watch completes the initialization of the service level connection (SLC) through the following steps 5 to 8 to complete the HFP connection establishment process. Among them, the mobile phone and the smart watch transmit and interact commands through the established communication link to complete the SLC initialization process.

[0200] Step 5: The mobile phone and the smart watch confirm the functions supported based on the HFP connection with each other.

[0201] Optionally, the smart watch sends the AT+BRSF command to the mobile phone to inform the mobile phone of the functions supported by the smart watch in the case of the establishment of the HFP connection. After the mobile phone confirms, it sends the +BRSF command to the smart watch, that is, it sends a confirmation response. Through the AT command interaction, the mobile phone and the smart watch confirm the functions that can be realized by both sides based on the HFP connection. For example, it can include the notification of the status of the call service, the three-way call function, the incoming call ringing notification, the volume control, etc.

[0202] Step 6: The mobile phone obtains the codec capabilities of the smart watch and selects the corresponding codec at the start of the call service.

[0203] Optionally, the smart watch sends the AT+BAC=<u1,u2,…> command to the mobile phone to inform the mobile phone of its codec capabilities, such as broadband codec capabilities, narrowband codec capabilities, etc. Based on the codec capabilities of the smart watch, the mobile phone selects the corresponding codec at the start of the call service to realize the subsequent information interaction process with the smart watch.

[0204] Step 7: Confirm the notification metrics supported by the mobile phone.

[0205] Optionally, the smart watch sends the AT+CIND=? command to the mobile phone to query the notification metrics supported by the mobile phone. That is, it queries the notification functions supported by the mobile phone and the corresponding metrics. The mobile phone sends the +CIND command to the smart watch to inform the smart watch of the current list of indicators actually supported by the mobile phone.

[0206] For example, if the mobile phone supports sending the status corresponding to the call service to the smart watch after receiving the call service, the indicator list includes the status corresponding to the call service that can be notified. Another example is the message notification service between the mobile phone and the smart watch. The mobile phone supports sending notification messages to the smart watch. Correspondingly, the smart watch supports the message notification service and can receive and parse the notification messages sent by the mobile phone.

[0207] Step 8: Confirm the current notification metric status of the mobile phone.

[0208] Optionally, the smartwatch sends the AT+CIND? command to the mobile phone to query the status of the current notification metrics of the mobile phone. The mobile phone replies to the smartwatch with the +CIND command, which contains the status of the current notification metrics of the mobile phone.

[0209] For example, based on the +CIND command, the smartwatch confirms that the mobile phone is processing a call service, and the status corresponding to the call service is the dialing state.

[0210] The above steps 1 to 8 are the HFP connection establishment process initiated by the mobile phone. Correspondingly, the HFP connection establishment process can also be initiated by the smartwatch.

[0211] For example, when the smartwatch detects an operation to turn on Bluetooth, it actively sends profile information to the mobile phone to establish a communication link. Then, the HFP connection establishment process is completed through the above steps 5 to 8. Among them, the specific HFP connection establishment process can refer to the prior art and will not be elaborated here.

[0212] It should be noted that when the smartphone is powered on, the smartwatch initializes the HFP service and the message notification service. That is, the identifier of the HFP service and the identifier of the message notification service are added to the service list supported by the smartwatch. Subsequently, by querying the service list, it can be known that the smartwatch supports the HFP service and the message notification service.

[0213] Optionally, after establishing a Bluetooth connection between the mobile phone and the smartwatch, the mobile phone can send notification messages to the smartwatch via Bluetooth wireless transmission.

[0214] For example, Application A in the mobile phone that is used to connect to the wearable device supports the message notification service, and the mobile phone can send notification messages to the smartwatch through Application A. Among them, Application A can be Figure 5 the shown sports health APP.

[0215] Exemplarily, as Figure 9 shown, the mobile phone and the smartwatch establish a wireless connection through Bluetooth connection. Among them, an HFP connection is established between the mobile phone and the smartwatch. Application A of the mobile phone sends notification messages to the smartwatch via Bluetooth transmission. After being processed by the processor of the smartwatch, the content of the notification message is confirmed and corresponding actions are executed.

[0216] It can be understood that Figure 9 the structure shown in Figure 9 does not constitute a specific limitation on the mobile phone and the smartwatch. The mobile phone and the smartwatch may have more or fewer components than those shown in

[0217] S403. The smartwatch determines whether the current mobile phone needs to handle the first call service. If not, it disconnects the HFP connection.

[0218] Optionally, based on the HFP connection, the smartwatch determines whether the current mobile phone needs to handle the first call service. If the current mobile phone does not need to handle the first call service, the smartwatch sends a request to disconnect the HFP connection to the mobile phone. After receiving the disconnection HFP request, the mobile phone disconnects the HFP connection and sends a response to the smartwatch. If the current mobile phone needs to handle the first call service, after the first call service is completed, the smartwatch sends a request to disconnect the HFP connection to the mobile phone to disconnect the HFP connection with the mobile phone.

[0219] Exemplarily, as Figure 9 shown, the smartwatch sends a request to disconnect the HFP connection to the Bluetooth module of the mobile phone through its Bluetooth module. After the mobile phone disconnects the HFP connection, it sends a response to disconnect the HFP connection to the smartwatch. Also, the Bluetooth module of the mobile phone notifies the audio management module that the audio channel between the current mobile phone and the smartwatch has been disconnected. Subsequently, based on the state of the disconnected HFP connection, the audio management module determines that the audio channel between the Bluetooth module of the mobile phone and the Bluetooth module of the smartwatch has been disconnected, and thus will not send the call task to the Bluetooth module of the mobile phone. That is, the smartwatch will not be used to handle call services.

[0220] In a possible implementation, the smartwatch can use the method of querying the status corresponding to the call service to confirm whether the current mobile phone needs to handle the first call service. For example, if the mobile phone receives a call service, it will send the call status parameter to the smartwatch that has established an HFP connection with it based on the HFP connection, so that the smartwatch can determine the type of the call service. Subsequently, the smartwatch calls the AT command to query the status parameter corresponding to the current mobile phone call service, and then it can confirm the type of the current mobile phone call service. For example, the AT command is the AT+CLCC command, which is used to list the current calls.

[0221] As shown in Table 1 below, it is the query result of the AT+CLCC command and the meaning of the query result. Among them, the first call service corresponds to multiple states, that is, if the call service is the first call service, the query result is one or more of the results from 1 to 6. Since the status of the second call service is updated relatively fast, it is configured to correspond to a single query result of 0. That is, if the call service is the second call service, the query result is 0. The smartwatch can determine whether the current mobile phone needs to handle the first call service according to the query result. It can be understood that if there is no corresponding query result for the AT+CLCC command, it means that there is no call service on the current mobile phone. Then, the smartwatch can directly send a request to disconnect the HFP connection to the mobile phone.

[0222] Table 1

[0223] Query Result Corresponding Status 0 Active State 1 Held 2 Dialing 3 Alerting 4 Incoming Call 5 Waiting 6 Call Held by Response and Hold

[0224] It should be noted that the call service provided in general third-party instant messaging applications is the second call service. When the mobile phone receives a call service triggered by a third-party instant messaging application, the Active state in Table 1 above will be correspondingly generated. However, if the mobile phone generates multiple states during the process of processing the call service triggered by some third-party instant messaging applications, then the call service provided by such third-party instant messaging applications also belongs to the first call service.

[0225] It should be noted that wearable devices capable of processing the second call service can be pre-configured, such as Bluetooth headsets and other devices that facilitate user calls. Such wearable devices do not need to send a request to disconnect the HFP connection to the mobile phone, that is, they do not need to actively disconnect the HFP connection.

[0226] Exemplarily, the user can wear the Bluetooth headset on the ear. During the process of processing the second call service, the user only needs to operate the mobile phone to process the second call service. Then, the Bluetooth headset can be pre-configured as a wearable device capable of processing the second call service and does not need to actively disconnect the HFP connection with the mobile phone.

[0227] S404. After disconnecting the HFP connection, when the mobile phone receives a call service, determine the current call service type. If it is the second call service, execute step S405; if it is the first call service, execute step S406.

[0228] Among them, the call service type includes the first call service and the second call service. The first call service includes services such as answering calls and making calls in the call application. The second call service includes services such as short voice message chats, audio calls, and video calls in third-party instant messaging applications (such as the "WeChat" application, the "QQ" application, video conferencing applications, etc.).

[0229] Optionally, after the mobile phone receives the first call service, it will send a system broadcast message to notify each registered application module that the mobile phone has received the first call service. Among them, application A of the mobile phone needs to register to listen for this broadcast message to determine the current call service type of the mobile phone. If application A receives the broadcast message, it determines that the call service currently received by the mobile phone is the first call service.

[0230] Optionally, the mobile phone can also determine the call service type by detecting a second operation. The second operation is used to indicate the execution of the call service. For example, if the second operation is an operation of making a call or answering a call, and the mobile phone detects the second operation, it confirms that the mobile phone has received the first call service. Another example is that if the second operation is an operation of playing a short voice or recording a short voice, and the mobile phone detects the second operation, it confirms that the mobile phone has received the second call service.

[0231] In some embodiments, the mobile phone can also determine the call service type in other ways. For example, by monitoring the hardware status of the mobile phone to obtain the call service type received by the mobile phone. For example, by monitoring changes in the user interface (UI) of the mobile phone, changes in the speaker status, changes in the microphone status, etc., to determine whether the current call service is the first call service or the second call service. For example, the UI interface of the first call service of the mobile phone is the interface of the call function, such as the answering call page. When it is monitored that the UI interface of the mobile phone switches to display the answering call page, it is determined that the call service type currently received by the mobile phone is the first call service.

[0232] S405. The call service is the second call service, and the mobile phone processes the second call service.

[0233] Optionally, as described in step S403 above, the smartwatch has already disconnected the HFP connection with the mobile phone. Then, as Figure 9 shown, when the mobile phone receives the second call service generated by the first application, the audio management module detects the currently available module for playing sound or the recording module. The audio management module determines that there is no currently paired Bluetooth device, and then does not call the Bluetooth module to process the second call service. Instead, the audio management module will call the audio module of the mobile phone itself to process the call service. For example, the audio management module calls the speaker to play sound. Or, it calls the microphone to record. Among them, the first application is, for example, a third-party instant messaging application, and the second call service, for example, includes playing the audio of the first application or recording audio, or video calls, audio calls, etc.

[0234] Exemplarily, as Figure 10 shown in (a) of the main interface 1001, a third-party instant messaging application in the mobile phone, such as a social APP, receives a message. In response to the user's operation of clicking on the social APP icon 101, the mobile phone opens the social APP and displays the interface 1002 as shown in Figure 10 (b). In response to the user's operation of clicking on the unread message icon 102, the interface 1003 as shown in Figure 10 (c) is displayed. On the chat interface 1003, when the mobile phone detects the user's operation of clicking on the short voice message icon 103, it means that the mobile phone has received the second call service of playing the unread short voice message, and the audio management module needs to select the module for playing sound. At this time, as Figure 9 shown, based on the already disconnected HFP connection, the audio management module determines that there is no currently paired Bluetooth device. As shown in Figure 10 (d) of the interface 1004, the audio management module directly calls the mobile phone speaker to play the current short voice message. During this process, the mobile phone can process the second call service relatively quickly without the user noticing.

[0235] Alternatively, as shown in the main interface 1101 in (a) of Figure 11 , after the mobile phone detects the operation of the user clicking on the social APP icon 111, the interface 1102 as shown in (b) of Figure 11 is displayed. In response to the operation of the user clicking on the icon 112, the interface 1103 as shown in (c) of Figure 11 is displayed. On the interface 1103, when the mobile phone detects the operation of the user clicking on the icon 113, it means that the user needs to send a short voice message. That is, when the mobile phone receives the second call service for recording a short voice message, the audio management module needs to select the module for receiving sound. At this time, as shown in Figure 9 , based on the disconnected HFP connection, the audio management module determines that there is no currently paired Bluetooth device. As shown in the interface 1104 in (d) of Figure 11 , the audio management module directly calls the mobile phone microphone to record a short voice message. As shown by the icon 114 in the interface 1104, it is used to prompt the user that a short voice message is being recorded. During this process, the mobile phone can process the second call service relatively quickly, and the user does not have to wait, so as to improve efficiency.

[0236] It should be noted that if the HFP connection between the mobile phone and the smart watch is not disconnected in the above step S403. In one scenario, as shown in Figure 12 , if the HFP connection between the mobile phone and the smart watch is not disconnected. Then, in the case of the HFP connection, after the mobile phone receives the second call service, the mobile phone Bluetooth module will send an eSco establishment request to the smart watch Bluetooth module. In response to the eSco establishment request, the smart watch establishes an eSco with the mobile phone. After the eSco is established, the mobile phone Bluetooth module will notify the audio management module that the audio channel between the mobile phone and the smart watch has been established. After that, if the smart watch confirms that the current call service type processed by the mobile phone is the second call service, it will disconnect the eSco with the mobile phone. Correspondingly, the mobile phone Bluetooth module will notify the audio management module that the audio channel between the mobile phone and the smart watch has been disconnected. Only then can the mobile phone process the second call service through its own speaker or microphone and other audio modules.

[0237] Exemplarily, in the short voice playback scenario as shown in (c) of Figure 10 , in response to the operation of the user clicking on the short voice message icon 103. After the smart watch establishes an eSco with the mobile phone, the audio management module will send the audio data to the smart watch through the link 121 as shown in Figure 12 , that is, the established audio channel, and the speaker of the smart watch will play it until the eSco is disconnected. During this process, if the user does not pay attention to the smart watch, it may cause the loss of audio data. And, during the process of the mobile phone switching the audio data to the mobile phone speaker for playback, an abnormality may occur. As shown in Figure 12As shown, if the switch is normal, the audio management module will send audio data to the mobile phone speaker through link 122. If the switch is abnormal, the audio management module will send audio data to the mobile phone earpiece through link 123. As Figure 10 shown in interface 1005 in (e) of Figure 10 , it is the interface displayed on the mobile phone when the switch is abnormal. The mobile phone displays a prompt box 104 on interface 1005 to prompt the user that the mobile phone is currently playing voice in earpiece mode. At this time, the sound is relatively small and the user experience is poor. Also, as Figure 11 shown in the short voice recording scenario in (c) of Figure 11 , since there is a time-consuming process for the above mobile phone to establish eSco with the smartwatch until it disconnects eSco. Then, on interface 1103, in response to the user's operation of clicking icon 113, the mobile phone displays interface 1105 as Figure 11 shown in (e) of Figure 11 . An icon 115 is displayed on interface 1105 to prompt the user to wait for recording. The mobile phone cannot start recording voice until eSco is disconnected, and the user experience is poor.

[0238] In another scenario, as Figure 13 shown, if the HFP connection between the mobile phone and the smartwatch is not disconnected. Then, after the mobile phone receives the second call service, the mobile phone Bluetooth module will send an eSco establishment request to the smartwatch Bluetooth module. After receiving the request, the smartwatch will not establish eSco with the mobile phone temporarily. Instead, it will first confirm the type of call service being processed by the current mobile phone. If it is the second call service, it will send a response rejecting the establishment of eSco to the mobile phone. After the mobile phone confirms that the smartwatch rejects the establishment of eSco, it will send at least one eSco establishment request according to the type of eSco data packet. Until all the establishment requests corresponding to the eSco data packet types are rejected by the smartwatch, the mobile phone confirms that the eSco establishment fails. The mobile phone Bluetooth module notifies the audio management module that the audio channel between the mobile phone and the smartwatch fails to be established. After that, the mobile phone can process the second call service through its own audio modules such as the speaker or microphone.

[0239] Exemplarily, in the short voice playback scenario shown in (c) of Figure 10 , or in the short voice recording scenario shown in (c) of Figure 11 , during the process of the above smartwatch confirming the type of mobile phone call service and the mobile phone and the smartwatch repeatedly requesting to establish eSco, the mobile phone needs to wait continuously until the mobile phone confirms that the eSco establishment fails. That is to say, during the above process, the user needs to wait for short voice playback or wait for short voice recording, which affects the user experience.

[0240] ​​​​It can be seen that, compared with the above two example scenarios, through the above step S403, the smart watch actively disconnects the HFP connection with the mobile phone, ensuring that the mobile phone will not detect the smart watch when receiving the second call service. Then, the mobile phone can directly select to use its own audio module to process the second call service, reducing the time consumption and avoiding audio data loss. Moreover, the user can operate only one mobile phone to process the second call service, reducing the user operation difficulty.

[0241] S406. The call service is the first call service, and the mobile phone sends a first notification to the smart watch.

[0242] Among them, the first notification is used to instruct the smart watch to process the first call service. The first notification may, for example, include an incoming call notification message or an outgoing call notification message.

[0243] Optionally, as described in the above step S404, after the application A in the mobile phone receives the system broadcast message and determines that the current call service is the first call service, it sends a first notification to the smart watch. After receiving the first notification, the smart watch can learn that the current mobile phone has received the first call service. Or, the application A learns the first call service received by the mobile phone through other pre-configured methods, such as monitoring the hardware status of the mobile phone, and sends a first notification to the smart watch.

[0244] Optionally, the first notification is a notification message in a pre-configured format between the mobile phone and the smart watch. For example, the first notification is a message in a fixed format. After receiving the first notification, the smart watch can directly parse the message or learn that the mobile phone has received the first call service according to the message identifier.

[0245] Exemplarily, as Figure 14 shown, the application A confirms that the mobile phone has received the first call service, such as the call service of answering a call. The application A uses the link 141 to send the first notification to the smart watch through Bluetooth transmission. The processor of the smart watch receives and parses the first notification, and learns that the mobile phone has received the first call service.

[0246] It should be noted that after the mobile phone receives the first call service and the second call service, it can send a notification message to the smart watch. For example, after the mobile phone receives the second call service, it sends a second notification to the smart watch. According to the second notification, the smart watch confirms that the current mobile phone has received the second call service, and then does not process the current call service.

[0247] S407. The smart watch and the mobile phone establish an HFP connection.

[0248] Optionally, after receiving the first notification, the smartwatch determines that the current mobile phone has received the first call service, and then sends a request to establish an HFP connection to the mobile phone. In response to the request to establish an HFP connection, the mobile phone sends a response to establish an HFP connection to the smartwatch and establishes an HFP connection with the smartwatch through the steps of establishing an HFP connection in step S402 above.

[0249] Exemplarily, as Figure 14 shown, the smartwatch calls the Bluetooth module to send an HFP connection establishment request to the mobile phone Bluetooth module. After receiving the HFP connection establishment request, the mobile phone agrees to establish an HFP connection and sends a response to establish an HFP connection to the smartwatch. Based on the re-established HFP connection, the mobile phone Bluetooth module notifies the audio management module that the Bluetooth audio channel between the current mobile phone and the smartwatch has been established.

[0250] S408. Based on the HFP connection, the mobile phone processes the first call service.

[0251] Optionally, the mobile phone determines that an HFP connection has been established with the smartwatch. Based on the HFP connection, the mobile phone sends an eSco establishment request to the smartwatch. After the smartwatch agrees, the mobile phone sends audio data to the smartwatch and / or receives audio data sent by the smartwatch to complete the processing of the first call service. In this way, after receiving the first call service, the mobile phone notifies the smartwatch, causing the smartwatch to actively establish an HFP connection with the mobile phone. Thus, it is possible to conveniently and quickly process the first call service using the smartwatch.

[0252] Exemplarily, as Figure 14 shown, after the HFP connection between the mobile phone and the smartwatch is successfully established, the audio management module determines that the modules available for processing audio currently include audio modules such as the Bluetooth module, the speaker, and the microphone. The audio management module selects the Bluetooth audio module with a high priority as the input / output module for audio data. That is, the mobile phone selects the device connected through the HFP connection to process the first call service, and uses the smartwatch to answer or make a call. As Figure 14 shown, the mobile phone plays the audio data using the speaker of the smartwatch and collects the audio data using the microphone of the smartwatch. That is, the mobile phone sends the audio data to the smartwatch and receives the audio data sent by the smartwatch, thereby completing the call. Among them, the priority of the input / output module of the audio data is pre-configured in the mobile phone. Generally, the priority of the mobile phone Bluetooth module is higher than that of the mobile phone speaker and microphone modules.

[0253] It should be noted that during the process of the smartwatch and the mobile phone re - establishing the HFP connection, the audio management module of the mobile phone may have queried once whether there is an established audio channel. After that, after the HFP connection is re - established, the audio management module detects the audio channel again. Among them, the HFP re - establishment process takes an extremely short time, which can ensure that the HFP connection is re - established without the user's awareness. Then, the mobile phone receives the operation of the user starting to execute the first call service, such as clicking the answer - call button. At this time, the audio channel has been established, and the audio management module directly processes the audio data using Bluetooth based on this audio channel, without causing audio data loss.

[0254] S409. After the first call service ends, the smartwatch disconnects the HFP connection.

[0255] Optionally, after the smartwatch finishes processing the first call service, it will actively release the HFP connection with the mobile phone. In this way, it not only ensures that the mobile phone can use the smartwatch to process the first call service, but also ensures that when the mobile phone receives the second call service next time, it will not send an eSco establishment request to the smartwatch based on the HFP connection, avoiding abnormal call situations. That is to say, after the smartwatch actively releases the HFP connection, the above - mentioned steps S404 - S409 are executed cyclically.

[0256] It can be seen that in the Bluetooth communication method provided by this application, when the mobile phone has no first call service, the wearable device can actively release the HFP connection with the mobile phone. In this way, subsequent problems such as audio data stream loss, abnormal voice switching, and waiting delay will not occur when the mobile phone receives the second call service. And when the mobile phone receives the first call service, it can enable the wearable device to know that the current mobile phone is processing the first call service. The wearable device actively establishes an HFP connection with the mobile phone, and then based on the HFP connection, the mobile phone can use the wearable device to process the first call service. In this way, the efficiency of the mobile phone in processing the first call service and the second call service is improved, which is convenient for user operation and enhances the user experience.

[0257] The above - mentioned method is not only applicable to the scenario of telephone voice messages, but also applicable to the scenario of voice messages for third - party applications. Usually, a first application program is installed on the mobile phone. Correspondingly, a watch version of the first application program is installed on the smartwatch, or the first application program may not be installed on the smartwatch. The mobile phone and the smartwatch have established an HFP service, and when the mobile phone does not need to process a call, it can automatically disconnect the HFP service. Then, when the mobile phone detects the operation of the user clicking to play the voice message in the first application program, it can directly play the voice message because the HFP service is disconnected at this time, thus avoiding the delay caused by the mobile phone detecting the HFP service.

[0258] In the embodiments of the present application, an APP corresponding to a smart watch is usually installed in a mobile phone, which is usually developed by a mobile phone manufacturer and a smart watch manufacturer. A user can set the smart watch in the APP, such as operations like switching the watch face and adding a new device. Among them, the signaling for the settings is usually a proprietary Bluetooth protocol. In the embodiments of the present application, the HFP service can be disconnected through the APP to avoid latency.
