Description

TECHNICAL FIELD

[0001] Embodiments of the present disclosure relate to the technical field of communication, and more particularly, to a Bluetooth state switching method and device in a dual system, an apparatus, and a medium. BACKGROUND

[0002] For an electronic device with a dual system, when the first processor is in a sleep state, the second processor takes over the system control right. If a user needs to use a Bluetooth function, since the Bluetooth module is integrated in the first processor, the first processor needs to be switched from a sleep state to a working state at this time, the second processor releases the system master control right to the first processor, the first processor quickly powers up the Bluetooth module, and then the user enters a Bluetooth setting interface, so that the first processor performs pairing and connection with an external Bluetooth device, and then uses the external Bluetooth device.

[0003] This brings a problem that there is a certain time consumption in switching between the first processor and the second processor. The user needs to wait for a switching process to enter the Bluetooth setting interface and complete Bluetooth communication connection with the external Bluetooth device. The user can obviously perceive the delay of system switching and the waiting of Bluetooth connection, which destroys the real-time and continuity of operation. SUMMARY

[0004] Embodiments of the present disclosure aim to provide a new technical solution for Bluetooth state switching in a dual system.

[0005] According to a first aspect of embodiments of the present disclosure, a Bluetooth state switching method in a dual system is provided, applied to a first electronic device, the first electronic device including a first processor, a second processor, and a Bluetooth module, and the method includes: Before the first processor enters a sleep state, the first processor sends Bluetooth connection information of a Bluetooth communication connection that has been established with a second electronic device to the second processor; The second processor configures the Bluetooth module to maintain the Bluetooth communication connection with the second electronic device according to the Bluetooth connection information; After the second processor successfully maintains the Bluetooth communication connection, the first processor enters a sleep state and keeps power supply to the Bluetooth module during the sleep. Optionally, after the second processor successfully maintains the Bluetooth communication connection, the first processor enters a sleep state, including: After the second processor successfully maintains the Bluetooth communication connection, the second processor sends a takeover success message to the first processor; The first processor enters a sleep state in response to the takeover success message.

[0006] Optionally, the method further includes: In response to the wake-up request, the first processor sends a status acquisition request to the second processor; In response to the status acquisition request, the second processor sends the Bluetooth connection information of the currently maintained Bluetooth communication connection with the second electronic device to the first processor; The first processor configures the Bluetooth module to restore the Bluetooth communication connection with the second electronic device based on the Bluetooth connection information; After the first processor restores the Bluetooth communication connection, the second processor releases control of the Bluetooth module.

[0007] Optionally, after the first processor restores the Bluetooth communication connection, the second processor releases control of the Bluetooth module, including: After the first processor restores the Bluetooth communication connection, the first processor sends a takeover completion message to the second processor; In response to the takeover completion message, the second processor releases control of the Bluetooth module.

[0008] Optionally, the Bluetooth connection information includes at least one of the following: the device address of the second electronic device, the link key, the currently active Bluetooth profile, and the logical transport channel identifier.

[0009] Optionally, the first processor and the second processor communicate via a dual-machine communication connection. The dual-machine communication connection includes one of the following: Universal Asynchronous Receiver Transmitter (UART), Serial Peripheral Interface (SPI), Universal Serial Bus (USB), or shared memory mechanism.

[0010] Optionally, the first processor is an application processor running the Android operating system, and the second processor is a communication processor running a real-time operating system.

[0011] According to a second aspect of the present disclosure, a Bluetooth state switching device in a dual-system is provided, applied to a first electronic device, the first electronic device including a first processor, a second processor, and a Bluetooth module, the device comprising: The sending module is used to send the Bluetooth connection information of the Bluetooth communication connection currently established with the second electronic device to the second processor before the first processor enters a sleep state. A configuration module is used by the second processor to configure the Bluetooth module according to the Bluetooth connection information to maintain the Bluetooth communication connection with the second electronic device; The control module is configured to allow the first processor to enter a sleep state after the second processor successfully maintains the Bluetooth communication connection, and to maintain power supply to the Bluetooth module during the sleep period.

[0012] According to a third aspect of the present disclosure, an electronic device is provided, comprising: a memory for storing executable computer instructions; and a processor for executing the method described in accordance with the first aspect above, under the control of the executable computer instructions. According to a fourth aspect of the present disclosure, a computer-readable storage medium is provided that stores computer instructions thereon, which, when executed by a processor, perform the method described in the first aspect above. One beneficial effect of this disclosure is that, for a first electronic device with dual systems, before the first processor goes into sleep mode, the first processor can smoothly migrate the Bluetooth communication connection to the second processor. Since the second processor directly uses the Bluetooth connection information transmitted by the first processor when taking over, the second processor can maintain the existing Bluetooth communication connection in a very short time.

[0020] <Hardware Configuration> Figure 1 This is a block diagram of the hardware configuration of an electronic device 1000 according to an embodiment of the present disclosure.

[0021] Electronic device 1000 can be a first electronic device or a second electronic device. For example, the first electronic device can be a smartwatch or a smart bracelet, and the second electronic device can be a mobile phone or headset.

The input device 1600 includes, for example, a touchscreen, a keyboard, or a gamepad. The electronic device 1000 can output audio information via a speaker 1700 and acquire audio information via a microphone 1800.

[0024] Those skilled in the art should understand that, although in Figure 1 The present specification shows a number of devices of electronic device 1000. However, the electronic device 1000 of the embodiments of this specification may only involve some of the devices, or may also include other devices, which is not limited here.

[0025] In this embodiment, the memory 1200 of the electronic device 1000 is used to store instructions for controlling the processor 1100 to operate in order to implement or support the implementation of a Bluetooth state switching method in a dual system according to any embodiment. Those skilled in the art can design instructions based on the scheme disclosed in this specification. How the instructions control the processor to operate is well known in the art and will not be described in detail here.

[0026] In the above description, those skilled in the art can design instructions based on the solutions provided in this disclosure. How the instructions control the processor to operate is well known in the art, and therefore will not be described in detail here.

[0027] Figure 1 The electronic devices shown are for illustrative purposes only and are not intended to limit this disclosure, its application, or its use.

[0028] <Method Implementation> Figure 2 This disclosure illustrates a Bluetooth state switching method in a dual-system according to an embodiment. This Bluetooth state switching method can be executed by a first electronic device, such as a smartwatch or smart bracelet. The first electronic device may include a first processor, a second processor, and a Bluetooth module. Figure 1 The electronic device shown is 1000. (For example...) Figure 2 As shown, the Bluetooth state switching method in the dual system of this embodiment may include the following steps S2100 to S2300: In step S2100, before the first processor enters a sleep state, the first processor sends the Bluetooth connection information of the Bluetooth communication connection currently established with the second electronic device to the second processor.

[0029] In this system, the first processor can be an application processor (AP) running the Android operating system, and the second processor can be a communication processor (CP) running a real-time operating system. The Bluetooth module is typically physically integrated into the hardware platform where the first processor resides. The first processor can be used as the main processor of the first electronic device, and the second processor as its slave processor. At any given time, typically only one processor, such as the first or second processor, has the main control of the first electronic device. That is, only one processor has control over external devices and the user interface at any given time. Furthermore, the first electronic device can switch between the first and second processors based on its own device state.

[0030] The first processor and the second processor can communicate through a dual-machine communication connection, which includes one of the following: Universal Asynchronous Receiver / Transmitter (UART), Serial Peripheral Interface (SPI), Universal Serial Bus (USB), or shared memory mechanism.

[0031] The Bluetooth connection information may include at least one of the following: the device address of the second electronic device, the link key, the currently active Bluetooth profile, and the logical transport channel identifier. The device address of the second electronic device is used to uniquely identify it. The link key is used for encrypted communication and security authentication. The currently active Bluetooth profile can be used to define the type of service currently in use, such as audio transmission or hands-free calling. The logical transport channel identifier ensures precise control of the data transmission pipeline. Using the Bluetooth connection information, the second processor can continue to process the same services (profile) and communicate with the second electronic device using the exact same identity (device address), the same security credentials (link key), and through the same pipeline (logical channel), thus ensuring that the Bluetooth communication connection is never interrupted from the perspective of both the second electronic device and the user.

[0032] In this embodiment, when the first processor is operational, it has primary system control. If the first electronic device needs to establish a Bluetooth communication connection with the second electronic device, the first processor will supply power to the Bluetooth module. The user can complete pairing and connection with the second electronic device through the Bluetooth settings interface of the first processor. The first processor can generate Bluetooth connection information for the currently established Bluetooth communication connection with the second electronic device through the Bluetooth protocol stack.

[0033] Typically, if the user does not operate the first electronic device for an extended period, the first processor will enter a sleep state to reduce system power consumption. Before entering sleep mode, the first processor can send the generated Bluetooth connection information to the second processor via a dual-device communication connection.

[0034] Before the first processor enters sleep mode, in step S2100 above, the first processor sends the Bluetooth connection information of the currently established Bluetooth communication connection with the second electronic device to the second processor, and then proceeds to: In step S2200, the second processor configures the Bluetooth module to maintain the Bluetooth communication connection with the second electronic device based on the Bluetooth connection information.

[0035] In this embodiment, after receiving Bluetooth connection information from the first processor, the second processor's lightweight Bluetooth protocol stack can directly access and configure the Bluetooth module to maintain the Bluetooth communication connection with the second electronic device. This means that the second processor impersonates the first processor and declares takeover to the second electronic device. The second electronic device acknowledges this switch, and the second processor successfully acquires communication rights with the second electronic device. At this point, audio streams or call data can be transmitted through the second processor.

[0036] After executing step S2200 above, in which the second processor configures the Bluetooth module to maintain the Bluetooth communication connection with the second electronic device based on the Bluetooth connection information, the process proceeds to: In step S2300, after the second processor successfully maintains the Bluetooth communication connection, the first processor enters a sleep state and continues to supply power to the Bluetooth module during the sleep period.

[0037] In this embodiment, after the second processor establishes a Bluetooth communication connection with the second electronic device, and sends a takeover success message to the first processor, the second processor will then send a takeover success message to the first processor through the two-machine communication connection. In response to this takeover success message, the first processor enters a low-power sleep state, continuing to supply power to the Bluetooth module during this period. After the first processor enters the sleep state, the second processor officially takes over the main control of the system. The user can operate Bluetooth functions, such as playing music and answering calls, through the second processor's interface or voice commands, with no difference in user experience compared to using the first processor.

[0038] In this embodiment, for a first electronic device with dual systems, before the first processor goes into sleep mode, the first processor can smoothly transfer the Bluetooth communication connection to the second processor. Since the second processor directly uses the Bluetooth connection information transmitted by the first processor when taking over, the second processor can maintain the existing Bluetooth communication connection in a very short time. After the second processor successfully maintains the Bluetooth communication connection, the first processor enters sleep mode and continues to supply power to the Bluetooth module during sleep mode. This achieves seamless switching of the Bluetooth connection with zero perception, ensures the continuity and stability of the Bluetooth communication connection, and greatly improves the user experience.

[0039] In one embodiment, the Bluetooth state switching method in the dual system of this disclosure further includes the following steps S3100 to S3400: In step S3100, the first processor responds to the wake-up request by sending a status acquisition request to the second processor.

[0040] In this embodiment, upon receiving a wake-up request, the first processor can respond to the wake-up request by sending a status acquisition request to the second processor to obtain Bluetooth connection information of the Bluetooth communication connection currently established with the second electronic device.

[0041] In step S3200, in response to the status acquisition request, the second processor sends the Bluetooth connection information of the currently maintained Bluetooth communication connection with the second electronic device to the first processor based on the dual-machine communication connection with the first processor.

[0042] In this embodiment, after receiving the status acquisition request, the second processor can respond to the status acquisition request by sending the Bluetooth connection information of the currently maintained Bluetooth communication connection with the second electronic device to the first processor based on the dual-machine communication connection with the first processor.

[0043] In step S3300, the first processor configures the Bluetooth module to restore the Bluetooth communication connection with the second electronic device based on the Bluetooth connection information.

[0044] In this embodiment, after receiving Bluetooth connection information from the second processor, the first processor's Bluetooth protocol stack can re-access and configure the Bluetooth module to restore the Bluetooth communication connection with the second electronic device. The second electronic device acknowledges this switch, and the first processor successfully acquires communication rights with the second electronic device. At this point, audio streams or call data can be transmitted through the first processor.

[0045] In step S3400, after the first processor restores the Bluetooth communication connection, the second processor releases control over the Bluetooth module.

[0046] In this embodiment, after the first processor restores the Bluetooth communication connection with the second electronic device, that is, after the first processor acquires the right to communicate with the second electronic device, the first processor sends a takeover completion message to the second processor through the dual-device communication connection with the second processor. In response to the takeover completion message, the second processor releases control of the Bluetooth module and releases the system master control to the first processor.

[0047] In this embodiment, for a first electronic device with dual systems, when the first processor is woken up, the second processor can smoothly migrate the Bluetooth communication connection to the first processor. Since the first processor directly uses the Bluetooth connection information transmitted by the second processor when taking over, the first processor can restore the existing Bluetooth communication connection in a very short time. This achieves seamless switching of the Bluetooth connection with zero perception, ensures the continuity and stability of the Bluetooth communication connection, and greatly improves the user experience.

[0048] <Example> The following example illustrates a Bluetooth state switching method in a dual-system setup, referring to... Figure 3 The Bluetooth state switching method in this dual system may include the following steps: Step S311: The system is powered on, the first processor obtains the main control of the system, the first processor supplies power to the Bluetooth module, and the system establishes a Bluetooth communication connection with the second electronic device through the Bluetooth configuration interface of the first processor.

[0049] In step S312, before the first processor officially enters the sleep state, it sends the Bluetooth connection information of the Bluetooth communication connection that has been established with the second electronic device to the second processor through the dual-machine communication connection with the second processor.

[0050] In step S321, the second processor directly accesses and configures the Bluetooth module based on the Bluetooth connection information to maintain the Bluetooth communication connection with the second electronic device, that is, the second processor obtains the right to communicate with the second electronic device.

[0051] In step S322, after the second processor obtains the right to communicate with the second electronic device, it sends a takeover success message to the first processor through the dual-machine communication connection with the first processor.

[0052] In step S313, after receiving the takeover success message, the first processor enters a sleep state and maintains power supply to the Bluetooth module during the sleep period, while the second processor acquires the main control of the system.

[0053] In step S314, upon receiving a wake-up command, the first processor sends a status acquisition request to the second processor via a dual-machine communication connection with the second processor.

[0054] In step S323, the second processor receives a status acquisition request and, through a dual-machine communication connection with the first processor, sends the Bluetooth connection information of the currently maintained Bluetooth communication connection with the second electronic device to the first processor.

[0055] In step S315, the first processor directly accesses and configures the Bluetooth module based on the Bluetooth connection information to restore the Bluetooth communication connection with the second electronic device, that is, the first processor restores the communication rights with the second electronic device.

[0056] In step S316, after the first processor regains communication rights with the second electronic device, it sends a takeover completion message to the second processor through the dual-machine communication connection with the second processor.

[0057] In step S324, after receiving the takeover completion message, the second processor releases control of the Bluetooth module and releases the system master control, and the first processor regains the system master control.

[0058] Through this example, firstly, users are completely unaware of the underlying system switching process when using Bluetooth in different system scenarios, resulting in smooth and continuous operation. Secondly, it eliminates the Bluetooth reconnection waiting time caused by system switching, achieving immediate availability of Bluetooth functionality. Thirdly, the underlying Bluetooth hardware resources are efficiently reused during the control periods of the first and second processors, avoiding redundant initialization and waste of resources. Fourthly, while ensuring functional continuity, reasonable power consumption control is achieved by putting the first processor to sleep and maintaining power only for Bluetooth.
