Description

Multi-system bluetooth state adjustment method, device, electronic equipment and storage medium

technical field

The present application relates to the field of computer technology, in particular, the present application relates to a multi-system bluetooth state adjustment method, device, electronic equipment and storage medium.

Background technique

At present, many smart mobile terminals can support multi-system mode, that is, multiple operating systems can run simultaneously on the same terminal, but generally there is only one Bluetooth device such as a Bluetooth chip on the same terminal. Therefore, how to enable multiple operating systems running on the same terminal to better use the same bluetooth device is a problem that needs to be solved.

In the solution of the prior art, in order to ensure that multiple operating systems do not conflict in resource occupation, the Bluetooth device can only establish a connection with the operating system currently in the foreground at the same time point (that is, there can only be one operating system at the same time point) operating system to enable the Bluetooth function). For example, when the operating system A in the background needs to enable the Bluetooth function, the end user needs to switch the operating system A to the foreground system. First turn off the Bluetooth function in operating system B and switch operating system B to the background, wait for operating system A to switch to the foreground before re-enabling the Bluetooth function in operating system A.

However, in the solution of the prior art, if the operating system A is switched from the foreground to the background when the Bluetooth state of the operating system A is turned on, and then the operating system A is switched from the background to the foreground, the Bluetooth state of the operating system A will default to In order to close, that is, it cannot guarantee the consistency of the Bluetooth state when the operating system A is still in the foreground after two switchings. The end user needs to turn on the Bluetooth function in the operating system A, so this method cannot meet the needs of some special scenarios. Business requirements, such as the scenario where the operating system is frequently switched and the Bluetooth function of operating system A needs to be kept on when it is in the foreground.

The following describes the technical solutions of the embodiments of the present application and the technical effects produced by the technical solutions of the present application by describing several exemplary implementations. It should be pointed out that the following embodiments may refer to, learn from or combine with each other, and the same terms, similar features, and similar implementation steps in different embodiments will not be described repeatedly.

Fig. 1 provides a schematic flow diagram of a multi-system bluetooth state adjustment method provided by an embodiment of the present application. The execution subject of the method may be an electronic device such as a terminal (such as a computer, a mobile phone), as shown in Fig. 1 , the method may include:

Step S101 , when a trigger operation of switching the first system from the foreground to the background is received, acquire the first Bluetooth status of the first system, and record the first Bluetooth status.

Wherein, when the operating system A is in the foreground, it means that the terminal is interacting with the user through the operating system A. When the operating system A is in the background, it means that the terminal does not interact with the user through the operating system A. The first system may be any operating system installed in the terminal, and the operating system may be referred to simply as the system if there is no ambiguity. The first bluetooth state is the bluetooth state when the first system is in the foreground before switching to the background.

Specifically, when the user switches the first system currently in the foreground to the background (that is, when performing a trigger operation of switching the first system from the foreground to the background), the terminal will record the first Bluetooth state of the first system. Specifically, taking the Android system as an example, the Bluetooth status can be divided into the following seven types: STATE_OFF (Bluetooth is turned off), STATE_TURNING_ON (Bluetooth is turning on), STATE_ON (Bluetooth is turned on), STATE_TURNING_OFF (Bluetooth is turning off), STATE_BLE_TURNING_ON (Bluetooth is turning off Power mode is turning on), STATE_BLE_ON (Bluetooth low energy mode is turned on), STATE_BLE_TURNING_OFF (Bluetooth low energy mode is turning off). The first Bluetooth state may be any one of the above seven states.

Step S102, when receiving the user's trigger operation to switch the first system from the background to the foreground, obtain the last recorded first Bluetooth state, and adjust the Bluetooth state of the first system based on the recorded first Bluetooth state.

Specifically, when the user switches the first system currently in the background to the foreground (that is, when the trigger operation of switching the first system from the background to the foreground is performed), the terminal will read the last recorded first Bluetooth state (that is, the first The bluetooth state when the first system was in the foreground last time), and then adjust the bluetooth state of the first system after switching to the foreground this time according to the recorded first bluetooth state.

In the solution provided by this application, whenever any operating system of the terminal is switched from the foreground to the background, the current Bluetooth state of the operating system is recorded, and when the operating system is switched back to the foreground again, the Bluetooth state of the operating system is recorded according to the record. Adjust to the state it was in when it was last in the foreground. The above method can ensure that when the operating system is switched, the Bluetooth state of each operating system in the foreground is consistent with the Bluetooth state when it was in the foreground last time, and then the Bluetooth function of the operating system in the foreground during the operating system switching process can be continuously Leave it on.

In an optional embodiment of the present application, when the trigger operation of switching the first system from the background to the foreground by the user is received, the last recorded first Bluetooth state is obtained, and the first bluetooth state is recorded based on the first recorded Bluetooth state. Adjust the bluetooth status of a system, including:

When receiving a trigger operation of switching the first system from the foreground to the background by the user, start counting time by a preset timer;

When the timing reaches the preset duration, obtain the last recorded first bluetooth state and the second bluetooth state of the second system switched to the background, if the second bluetooth state is off, then according to the last recorded first bluetooth state to adjust the Bluetooth status of the first system.

Wherein, the preset timer is used to start timing when a trigger operation of system switching is detected. The function of timing is that when the Bluetooth status of system A in the foreground is turned on before the system is switched, if system A is switched to the background, the Bluetooth status of system A needs to be adjusted to off; at this time, if system B in the foreground needs to turn on the Bluetooth If the state is turned on, you need to wait for the bluetooth state of system A to be turned off before turning on the bluetooth state of system B. At this time, you need to preset the timer to time the waiting time to prevent multiple systems from turning on at the same time Bluetooth is causing a resource conflict. The preset duration is generally a waiting duration to ensure that no resource conflict occurs during system switching. Exemplarily, in this embodiment of the application, it can be set to 1.5 seconds. The second system is the system switched to the background during the system switching operation. The second bluetooth state is the bluetooth state of the second system when switching to the background.

Specifically, when the user switches the first system from the background to the foreground, the preset timer of the terminal will start timing, and when the timing reaches the preset duration, the terminal will obtain the last recorded first Bluetooth status and second The second Bluetooth state of the system. At this time, if the second bluetooth state is off, the bluetooth state of the first system that is in the foreground after system switching is adjusted according to the first bluetooth state.

It should be noted that, if the obtained second bluetooth state is not off, the preset timer will re-time the preset duration until the second bluetooth state is obtained to be off.

In an optional embodiment of the present application, timing is started by a preset timer, which specifically includes:

When the timing duration is less than the preset duration and the trigger operation of any other system switching from the foreground to the background is received again, the preset timer is reset and timing is restarted.

Specifically, when the timing duration does not reach the preset duration, if the user switches the system again at this time, the preset timer resets the timing duration and starts a new timing.

It can be understood that when the system switching operation is performed again when the timing time does not reach the preset time length, the switching operation is a new switching operation, and at this time, it is necessary to wait for the Bluetooth status of the system currently in the background to be adjusted to off.

As shown in FIG. 2 , when the terminal receives a trigger operation of switching the first system from the background to the foreground, it will start counting time through a preset timer. If the trigger operation of other system switching is received again before the preset timer duration is reached, the preset timer duration will be reset and timing will be restarted; if the timer preset duration is reached, the first The second bluetooth state of the second system, if the obtained second bluetooth state is closed, then adjust the bluetooth state of the first system currently in the foreground according to the first bluetooth state recorded last time by the first system; If the second bluetooth status is not off, the preset timer is used to time the preset duration again.

In an optional embodiment of the present application, adjusting the Bluetooth state of the first system specifically includes:

If the first bluetooth state is turned on or is turning on, then adjust the bluetooth state of the first system to be turned on;

If the first bluetooth state is closed or is closing, adjust the bluetooth state of the first system to be closed.

Specifically, taking the Android system as an example, the turn-on process of Bluetooth needs to go through the following changes in sequence: STATE_BLE_TURNING_ON, STATE_BLE_ON, STATE_TURNING_ON, STATE_ON; the turn-off process of Bluetooth needs to go through the following changes in turn: STATE_TURNING_OFF, STATE_BLE_ON, STATE_BLE_TURNING_OFF , STATE_OFF. Therefore, if the bluetooth state is in the opening process, it belongs to the opening state; if the bluetooth state is in the closing process, it belongs to the closing state. The first bluetooth state will record the bluetooth state according to the change process of the bluetooth state. If the first bluetooth state is on or is being turned on, when the first system switches from the background to the foreground, the bluetooth state of the first system will be automatically adjusted to Open; if the first Bluetooth status is off or closing, when the first system switches from the background to the foreground, the Bluetooth status of the first system will remain off.

In an optional embodiment of the present application, acquiring the current first Bluetooth status of the first system specifically includes:

The first Bluetooth state of the first system is acquired by preset Bluetooth listening broadcast.

Among them, the preset Bluetooth monitoring broadcast is used to monitor the Bluetooth status of the system.

Specifically, when the user switches the first system from the foreground to the background, the terminal acquires the Bluetooth status of the first system when the system is switched through the preset Bluetooth monitoring broadcast, and records the acquired Bluetooth status as the first Bluetooth status.

It should be noted that usually there is only one bluetooth device in the terminal, and each system can adjust the state of the bluetooth device of the terminal by adjusting its own bluetooth state when it is in the foreground.

Optionally, in the embodiments provided in this application, a preset flag can also be set in each system, and the preset flag is used to indicate the process of any system sending the Bluetooth state change request to the terminal Bluetooth device. Exemplarily, the preset flag is 0 by default. When any system sends a Bluetooth status change request to the terminal's Bluetooth device but the terminal's Bluetooth device has not yet processed the change request, the preset flag can be set to 1. When the Bluetooth When the device adjusts the Bluetooth state according to the change request, the preset flag can be set to 2, and after the Bluetooth device adjusts the Bluetooth state, the preset flag changes back to 0 again. Setting preset flags can better prevent resource conflict issues. In the above example, when the preset flag in any system is 1 or 2, it means that the Bluetooth device is ready to process or is processing the Bluetooth state change request of this system, and will not process the Bluetooth state change requests of other systems at this time ( That is, the preset flag in other systems can only be 0).

In an optional embodiment of the present application, the method may also include:

Obtain the first physical address of the Bluetooth device;

Obtaining at least one second physical address according to the first physical address, and determining a physical address corresponding to the first system from the first physical address and each second physical address;

When the first system is in the foreground and the Bluetooth status is turned on and needs to be connected with the target external device through Bluetooth, the physical address corresponding to the first system is sent to the target external device, so that the target external device matches the first system according to the physical address. The system establishes a Bluetooth connection.

Wherein, both the first physical address and the second physical address are mac addresses (Media Access Control Address, physical addresses), which can be obtained by the manufacturer of the terminal upon application. The target external device is a device other than the terminal that needs to establish a Bluetooth connection with the terminal (such as a Bluetooth headset, etc.).

Specifically, the terminal manufacturer inputs the applied first physical address into the terminal as the first physical address of the terminal Bluetooth device for storage, and then sets the first physical address according to the first physical address in the terminal's hardware.bluetooth (Bluetooth hardware interface) service. In the way of obtaining at least one second physical address, the terminal obtains at least one second Bluetooth address according to the set method, and each system will determine a corresponding relationship with one of the physical addresses. When any first system is in the foreground and Bluetooth is turned on, and needs to establish a Bluetooth connection with the target external device, the terminal sends the physical address corresponding to the first system currently in the foreground to the target external device, and the target external device After receiving the physical address, establish a Bluetooth connection with the first system according to the physical address.

It should be noted that, because the physical address of the terminal is unique in the solution of the prior art, the physical address of the terminal can only correspond to one of the systems (such as system A). When other systems (such as system B) need to pass the Bluetooth When the device establishes a Bluetooth connection with the target external device, although it is displayed as connected, in fact System B does not successfully establish a Bluetooth connection with the target external device. Therefore, the solution provided by the embodiment of the present application obtains multiple physical addresses so that each system has its own corresponding physical address, ensuring that the target external device can successfully establish Bluetooth with the current foreground system according to the physical address corresponding to the current foreground system. connect.

In an optional embodiment of the present application, each second physical address is obtained by modifying the last value of the first physical address.

Among them, each physical address consists of 6 bytes, the first 3 bytes are assigned by the Institute of Electrical and Electronics Engineers and cannot be modified, and the last 3 bytes can be customized by the terminal manufacturer. Therefore, the last value of the first physical address can be modified to obtain multiple corresponding second physical addresses.

Specifically, the terminal manufacturer will first apply to the Institute of Electrical and Electronics Engineers for several physical addresses, then select one of all the applied physical addresses as the first physical address and store it in the terminal, and write related methods in the terminal to use The terminal can acquire other applied-for second physical addresses according to the first physical address. Since each physical address has a one-to-one correspondence with each system in the terminal, the number of second physical addresses may be the number of systems installed in the terminal minus one (that is, the first physical address also corresponds to one of the systems). Exemplarily, for a dual-system terminal, two consecutive physical addresses are applied for, and at this time, the smaller end value (ie, the last digit) of the two physical addresses is stored as the first physical address in the terminal ( It is usually stored in the non-volatile memory of the terminal), and write the method corresponding to "the second physical address is obtained by adding one to the last digit corresponding to the first physical address" in the hardware.bluetooth service, and the terminal will convert the first The last digit of the physical address is automatically increased by one to obtain the corresponding second physical address, and the first physical address and the second physical address are assigned to the two systems of the terminal respectively.

Fig. 3 is an example of interaction between two systems in a dual-system terminal provided by the present application. As shown in Fig. 3, both system 1 and system 2 are Android systems, which can be implemented in containers, etc., and are jointly subject to Kernel (kernel) control. In System 1 and System 2, there are APPs (Applications) that need to use Bluetooth respectively. The APPs can call enable() in BluetoothManagerService (Bluetooth Management Service) through SettingsLib (a dependent library for setting functions) in their respective systems. and disable() functions (respectively corresponding to opening and closing) to realize the opening and closing of the Bluetooth function in their respective systems. System 1 and System 2 can send their Bluetooth status to the kernel through their respective status channels, and the kernel can obtain the Bluetooth status of System 1 and System 2 and adjust the Bluetooth status of System 1 and System 2 respectively.

BluetoothManagerService can send the Bluetooth connection request of the target external device to Hardware.bluetooth.service. After receiving the Bluetooth connection request, Hardware.bluetooth.service obtains the corresponding physical address of the system and sends it to the kernel, and the kernel then sends the physical address to the target external device. device and establish a Bluetooth connection with the target external device.
