Background

The bluetooth core specification defines a number of modes for classical bluetooth connection states including, for example, active mode, sniff mode and Hold mode. The active mode and the breathing mode, the active mode and the holding mode may be switched to each other. In the active mode, the master device can try to use available resources to communicate, in the breathing mode, the master device and the slave device need to agree on a breathing interval, the master device and the slave device communicate at the agreed interval, the slave device sleeps during the interval, and in the holding mode, the slave device can sleep until the agreed holding mode time is up, and the slave device can not wake up.

The master device may enter an intermediate state (mode) during initiation of the breathing mode to the slave device, in which the master device is not allowed to issue data to the bluetooth chip of the master device. If the bluetooth chip of the master device fails to upload a success event or a failure event sent by the slave device to the master device in a scheduled time due to the device itself or environmental interference, the connection state between the master device and the bluetooth chip of the master device is caused to stay in an intermediate state all the time, so that the subsequent master device cannot issue any instruction to the bluetooth chip of the master device. The most direct effect is that the related Bluetooth remote control command cannot be issued to the slave device through the master device, so that the master device fails to control the slave device.

For easy understanding, a specific flow in the embodiments of the present application is described below, and referring to fig. 1, fig. 1 is a schematic flow diagram of an embodiment of a communication mode switching method based on bluetooth connection according to the embodiments of the present application.

In the embodiment shown in fig. 1, the method applied to the first device may include the steps of:

S101, when a triggering condition for starting a breathing mode is detected, a mode switching request is initiated to second equipment, and the instruction issuing authority of the first equipment is frozen.

It should be explained that the sniff mode is one of the classical bluetooth connection states for turning on when the bluetooth device does not need continuous communication to function to reduce power consumption. In the breathing mode, the Bluetooth device periodically disconnects and reestablishes the connection with the paired device, thereby achieving the effect of reducing energy consumption.

The breathing mode is typically not actively initiated by the device, but rather is automatically switched to the breathing mode when a trigger condition is detected to turn on the breathing mode when the device is in a hold mode or sleep mode. For example, when the first device is in the hold mode and it is detected that no data exchange occurs within the timeout waiting time, the first device may be considered to satisfy a trigger condition for starting the breathing mode, and the first device may automatically initiate a mode switching request to a second device connected to the first device via bluetooth, so as to request to switch the current communication mode to the breathing mode, so as to reduce power consumption of the device.

It should be noted that, in this scheme, the first device actually includes a master device control chip and a master device bluetooth chip, when the first device initiates a mode switching request to the second device to switch the current communication mode to the breathing mode, the master device control chip firstly sends a mode switching application to the master device bluetooth chip, after the master device control chip receives the application success information fed back by the master device bluetooth chip, the master device control chip automatically enters an intermediate state (mode), and the master device control chip is not allowed to issue data to the master device bluetooth chip in the intermediate state. The main reasons include the following:

1. Avoiding collisions, the second device may need to perform some specific operations to adapt to the new communication mode during the mode switch. If the first device sends other instructions at this time, it may collide with the requirement of the second device during the mode switching, so that the second device cannot respond correctly or perform the wrong operation.

2. Ensuring stability, mode switching is a sensitive process that requires the second device to centralize the resources to complete. The prohibition instruction issuing can reduce the data quantity which needs to be processed during the mode switching period of the second equipment, and ensure the stability and success rate of the mode switching process.

3. Preventing erroneous operation, the second device may not support certain device instructions or may not respond correctly to such instructions during the mode switch. Disabling instruction issue may prevent the second device from being subject to errors or malfunctions due to attempts to perform improper operations.

4. Resource management, the second device may need to reconfigure its bluetooth stack and hardware resources when switching modes. In this process, the second device may not be able to process the new instruction, so disabling instruction issue is to avoid wasting resources and possible resulting problems.

S102, recording the initiation time of the mode switching request, acquiring a target parameter value corresponding to a preset parameter which is currently used for influencing the communication quality, inputting the target parameter value into a pre-trained time determination model for performing time prediction operation, and obtaining predicted timeout waiting time.

It should be explained that, because the bluetooth chip of the second device or the master device of the first device may be affected by network quality or system resources, there is a certain time delay when the request feedback information is sent to the master device control chip of the first device, if the influence possibly caused by the time delay is ignored, the request feedback information may be mistakenly considered to be sent abnormally, so that the master device control chip card of the first device is directly in an intermediate state, and cannot continuously control the second device.

For example, when the second device receives the mode switching request, or the bluetooth chip of the master device of the first device forwards the request feedback information to the control chip of the master device of the first device, the current network quality of the second device or the bluetooth chip of the master device is poor, which causes that the bluetooth chip of the second device or the bluetooth chip of the master device cannot timely send data to the corresponding receiving end, and in fact, the bluetooth chip of the second device or the bluetooth chip of the master device may be able to send the data in the next second. When the timeout waiting time is fixed, the above listed situation is determined to be timeout transmission, and meanwhile, the master device of the first device may directly cause the chip card to be controlled in an intermediate state, and the second device cannot be controlled continuously.

For another example, when the second device receives the mode switching request, or the master bluetooth chip of the first device forwards the request feedback information to the master control chip of the first device, the current network quality of the second device or the master bluetooth chip is better, and under normal conditions, the second device or the master bluetooth chip can shorten the time of transmitting the data to the corresponding receiving end. When the timeout waiting time is fixed, even if the current network quality can meet the requirement of rapid data transmission, the current network quality needs to wait until the preset timeout waiting time is exceeded, and the current network quality is possibly judged to be in timeout transmission.

In summary, because the timeout waiting time is set to be too long or too short to bring adverse effects, in this embodiment, when a mode switching request is initiated to the second device, a target parameter value corresponding to a preset parameter currently used to affect the communication quality is acquired, the target parameter value is input into a pre-trained time determination model to perform a time prediction operation, so as to obtain a predicted timeout waiting time, and the timeout waiting time is a dynamic adjustment result.

S103, monitoring an execution result of the mode switching request.

It should be noted that, if the bluetooth chip of the master device of the first device fails to upload a success event or a failure event sent by the second device to the control chip of the master device within a stipulated time due to the self-cause or environmental interference of the device, the connection state between the control chip of the master device and the bluetooth chip of the master device will stay in an intermediate state all the time, so that the control chip of the subsequent device cannot issue any instruction to the bluetooth chip of the master device. The most direct effect is that the related Bluetooth remote control command cannot be issued to the second device through the first device, so that the first device fails to control the second device. Therefore, in this embodiment, it is necessary to monitor the execution result of the mode switching request and execute a corresponding operation according to the execution result.

And S104, if the execution result is that the request feedback information is not received after the timeout waiting time is exceeded, releasing the instruction issuing authority of the first equipment.

When the execution result is that the request feedback information returned by the second device is not received after the timeout waiting time is exceeded, in order to avoid that the connection state between the master device control chip and the master device Bluetooth chip stays in the intermediate state all the time, the subsequent device control chip cannot send any instruction to the master device Bluetooth chip. In this embodiment, conditions are created for the first device to initiate the mode switching request to the second device again by releasing the instruction issuing authority of the control chip of the master device in the first device.

S105, re-initiating a mode switching request to the second equipment.

In this embodiment, by re-initiating the mode switching request to the second device, the success rate of mode switching is improved, so that the first device is prevented from staying in the intermediate state for a long time, and the first device cannot continuously control the second device.

Meanwhile, in the scheme, when the request feedback information is not received after the timeout waiting time is detected to be exceeded, the target parameter value corresponding to the current preset parameter is acquired, and the timeout waiting time is redetermined, so that the timeout waiting time can be set to a smaller value when the timeout waiting time meets the requirement of down regulation, the first equipment can timely reinitiate the mode switching request to the second equipment, and the second equipment can rapidly respond to the mode switching request.

In some embodiments, as shown in fig. 2, before said S101, the method further comprises the steps of:

And acquiring a preset parameter value generated during each link management protocol interaction in the process of establishing Bluetooth connection between the first equipment and the second equipment.

In this embodiment, the preset parameters refer to various parameters capable of affecting the communication quality, and may include, but are not limited to, the following parameters:

The device type of the second device, such as a television, a mobile phone, a sound box, an earphone, a computer, etc.

The delay value, i.e. the last five times the first device had sent the link management protocol from the downlink to the second device, and then to the time average of the feedback information received from the second device (preferably the time corresponding to the last five downlink management protocols was averaged).

Signal Strength (RSSI) values.

The number of retransmissions, i.e. the average of the number of retransmissions required by the first five times from the downlink management protocol to the hit of the second device (preferably the average of the number of times corresponding to the last five downlink management protocols).

In this embodiment, a random gradient descent (SGD) algorithm is used to train the model and change the parameters of the model. During training, the random gradient descent algorithm optimizes the performance of the model by iteratively adjusting the parameters of the model to minimize the loss function. Specifically, the stochastic gradient descent algorithm calculates the gradient of the loss function with respect to the model parameters for each iteration and updates the parameters of the model based on these gradients and the learning rate. This process continues until the loss function value of the model reaches a preset threshold or the performance of the model is no longer significantly improved.

In some embodiments, as shown in fig. 2, after said S103, the method further comprises the steps of:

And S1031, if the execution result is that the switching permission feedback information returned by the second equipment is received within the timeout waiting time, switching the current communication mode between the first equipment and the second equipment to a breathing mode.

In this embodiment, when it is detected that the first device receives the feedback information that allows switching and is returned by the second device, and the feedback information is received within the timeout waiting time, and indicates that the engagement of the breathing mode has been completed between the first device and the second device, the current communication mode between the first device and the second device may be switched to the breathing mode. It should be noted that, the switching feedback information is specifically allowed to be uploaded to the master device bluetooth chip of the first device first, and then uploaded to the master device control chip of the first device by the master device bluetooth chip.

S1032, if the execution result is that the refused switching feedback information returned by the second equipment is received within the timeout waiting time, the current communication mode between the first equipment and the second equipment is not changed, and/or prompt information containing the refused switching feedback information is generated to prompt the user.

In this embodiment, when it is detected that the first device receives the feedback information of allowing switching returned by the second device, and the feedback information is received within the timeout waiting time, it indicates that the second device refuses the mode switching request initiated by the first device, and at this time, the current communication mode between the first device and the second device is continuously maintained. It should be noted that, the refused switching feedback information is specifically uploaded to the master device bluetooth chip of the first device, and then uploaded to the master device control chip of the first device by the master device bluetooth chip.

In other embodiments, a prompt may also be generated to prompt the user containing refusal to switch feedback information, such as "the second device is temporarily unable to switch to respiratory mode because there are important files to transmit".

In some embodiments, as shown in fig. 3, before said S105, the method further comprises the steps of:

S1041, obtaining the repeated initiation times of the current mode switching request;

in this embodiment, since the first device repeatedly initiates the mode switching request multiple times, the feedback information of the request cannot be received within the timeout waiting time, possibly because the first device or the second device has an abnormal device or other unknown reasons, if the mode switching request is still repeatedly initiated to the second device without limitation at this time, the user cannot be prompted timely, so as to take intervention measures to solve the problem that the second device cannot be normally controlled at present, and waste of system resources is caused.

S1042, judging whether the repeated starting times exceeds the preset times.

S1043, if the repeated initiation times exceeds the preset times, stopping initiating a mode switching request to the second equipment, and generating an equipment abnormality message to prompt a user.

In this embodiment, the number of repeated initiation may be set, for example, three times, and when the request feedback information cannot be received within the timeout waiting time for more than three times, the initiation of the mode switching request to the second device is stopped, and the device exception message is generated to prompt the user, where the user may attempt to repair by restarting the device or disconnecting the reconnection bluetooth.

In some embodiments, as shown in fig. 4, before said S101, the method further comprises the steps of:

S1011, checking the role state of the first device in the current Bluetooth local area network, wherein the role state comprises a central device or a peripheral device.

It should be explained that in bluetooth technology, devices in bluetooth local area networks are generally classified into two roles, central device (Central) and Peripheral device (Peripheral), which are the basis of Bluetooth Low Energy (BLE) communication mode.

Central device (Central) the Central device is responsible for discovery and connection of peripheral devices. In bluetooth local area networks, the central device typically plays the role of a client, which can actively search for and establish a connection with peripheral devices. Once the connection is established, the central device may read or write the services and features of the peripheral device.

Peripheral devices (Peripheral) provide services and features that can be discovered and connected by the central device. In bluetooth local area networks, a peripheral device typically plays the role of a server, broadcasting its own presence and available services so that a central device can discover and interact with it.

And S1012, if the role state of the first device is central equipment, increasing the initial polling interval between the first device and the second device on the premise of not exceeding the preset maximum polling interval.

In this embodiment, when the first device initiates a mode switching request to the second device, it needs to ensure that the first device is a central device in the current bluetooth local area network, so that the first device has the authority to modify the polling interval, where the polling interval refers to how often the first device sends a polling command to query the state or data of the second device, so as to ensure that the first device and the second device can maintain a connection state.

The first device with the right of modifying the polling interval increases the initial polling interval on the premise of not exceeding the maximum polling interval, so that the first device and the second device can not only keep a connection state, but also occupy excessive system resources due to frequent polling operation, and the influence of the first device in the process of initiating a mode switching request to the second device is reduced, thereby improving the successful hit rate of mode switching.

In some embodiments, as shown in fig. 4, after said S1011, the method further comprises the steps of:

And S1013, if the role state of the first device is a peripheral device, initiating a role exchange request to a central device in the current Bluetooth local area network so as to modify the role state of the first device into the central device, so that the first device has modification authority for modifying the polling interval between the first device and the second device.

In this embodiment, since the first device needs to ensure that the first device is a central device in the bluetooth local area network when initiating the mode switching request, when confirming that the first device is not the central device, a role exchange request is initiated to the central device in the current bluetooth local area network, that is, a master-slave role exchange request is initiated, so that the first device has the authority to modify the polling interval.

S1014, based on the modification authority, increasing an initial polling interval between the first device and the second device on the premise that a preset maximum polling interval is not exceeded.

In this embodiment, the first device having the right to modify the polling interval increases the initial polling interval on the premise that the maximum polling interval is not exceeded, so that the first device and the second device can not only maintain a connection state, but also occupy too many system resources due to frequent polling operation, and the influence of the first device in the process of initiating a mode switching request to the second device is reduced, thereby improving the successful hit rate of mode switching.

It can be seen that, according to the communication mode switching method based on bluetooth connection provided by the embodiment of the application, when the triggering condition of starting the breathing mode is detected, a mode switching request is initiated to a second device, the instruction issuing authority of the first device is frozen, the initiation time of the mode switching request is recorded, a target parameter value corresponding to a preset parameter which is currently used for influencing the communication quality is obtained, the target parameter value is input into a pre-trained time determination model to perform time prediction operation, a predicted timeout waiting time is obtained, the execution result of the mode switching request is monitored, if the execution result exceeds the timeout waiting time, the instruction issuing authority of the first device is released, and the mode switching request is initiated to the second device again. By setting a reasonable overtime waiting time, if the first device does not receive the request feedback information sent by the second device within the overtime waiting time, the instruction issuing authority of the first device is released, and the mode switching request is initiated to the second device again, so that the success rate of the communication mode switching is improved, and the situation that the second device cannot be controlled normally due to the lack of the instruction issuing authority of the first device is avoided. And the timeout waiting time is dynamically generated according to the current use scene, so that the method can be more in line with the current use scene, and the problem that the first device fails to normally receive the request feedback information due to the fact that the mode switching request is re-initiated to the second device in advance or delayed is avoided.

In some embodiments, in the embodiment shown in fig. 5, the method may also be applied to a second device, comprising the steps of:

s201, a mode switching request initiated by the first equipment is received.

This step can be understood by referring to the content of step S101 in fig. 1, and will not be described here.

S202, corresponding request feedback information is generated according to the mode switching request, and the request feedback information is sent to the first device.

In this embodiment, the corresponding request feedback information is given according to the mode switching request initiated by the first device, and the request feedback information is sent to the first device, so that the first device can execute the corresponding operation according to the request feedback information.

And S203, if the request feedback information is the feedback information allowing switching, switching the current communication mode between the first equipment and the second equipment to a breathing mode.

This step can be understood by referring to the content of step S1031 in fig. 2, and will not be described here.
