Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to the field of communication mode switching technology based on Bluetooth connection, and in particular to a communication mode switching method, device, medium and equipment based on Bluetooth connection. Background Art

[0002] The Bluetooth core specification defines multiple modes for classic Bluetooth connection states, including Active mode, Sniff mode, and Hold mode. Active mode and Sniff mode, as well as Active mode and Hold mode, can be switched between each other. In Active mode, the master device will try its best to use available resources for communication; in Sniff mode, the master device and the slave device need to agree on a Sniff interval, and both parties communicate at the agreed interval, and the slave device sleeps during the interval; in Hold mode, the slave device can sleep until the agreed Hold mode time expires, at which time it will wake up.

[0003] When the master device initiates the breathing mode to the slave device, the master device will enter an intermediate state (mode), in which the master device is not allowed to send data to the Bluetooth chip of the master device. If the Bluetooth chip of the master device fails to upload the success event or failure event sent by the slave device to the master device within the agreed time due to the device's own reasons or environmental interference, the connection state between the master device and the Bluetooth chip of the master device will remain in the intermediate state, resulting in the subsequent master device being unable to send any instructions to the Bluetooth chip of the master device. The most direct impact at this time is that the relevant Bluetooth remote control commands cannot be sent to the slave device through the master device, causing the master device to fail to control the slave device.

[0051] The embodiment of the present application provides a communication mode switching method based on Bluetooth connection. By using this method, a reasonable timeout waiting time is set. If the first device does not receive the request feedback information sent by the second device within the timeout waiting time, the command issuing authority of the first device is released, and a mode switching request is re-initiated to the second device, so as to improve the success rate of communication mode switching and avoid the first device being unable to control the second device normally due to lack of command issuing authority. In addition, the timeout waiting time is dynamically generated according to the current usage scenario, which can be more in line with the current usage scenario, avoiding the problem that the first device fails to receive the request feedback information normally due to the early or delayed re-initiation of the mode switching request to the second device.

[0055] For ease of understanding, the specific process in the embodiments of the present application is described below. Figure 1 , Figure 1A flow chart of an embodiment of a method for switching communication modes based on Bluetooth connection provided in an embodiment of the present application.

[0056] exist Figure 1 In the illustrated embodiment, the method is applied to a first device and may include the following steps:

[0057] S101, when a trigger condition for starting the breathing mode is detected, a mode switching request is initiated to the second device, and the instruction issuing authority of the first device is frozen.

[0058] It should be explained that breathing mode is a classic Bluetooth connection state, which is used to reduce power consumption when the Bluetooth device does not need to communicate continuously. In breathing mode, the Bluetooth device will periodically disconnect and re-establish the connection with the paired device to achieve the effect of reducing energy consumption.

[0059] The breathing mode is usually not initiated by the device, but when the device is in the hold mode or sleep mode, it detects the triggering condition for turning on the breathing mode and automatically switches to the breathing mode. For example, when the first device is in the hold mode and detects that no data exchange occurs within the timeout waiting time, it can be considered that the first device meets the triggering condition for turning on the breathing mode. The first device will automatically initiate a mode switching request to the second device connected to it by Bluetooth, requesting to switch the current communication mode to the breathing mode to reduce the power consumption of the device.

[0060] It should be noted that the first device in this solution actually includes a main device control chip and a main 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 main device control chip first sends a mode switching application to the main device Bluetooth chip. After the main device control chip receives the application success information fed back by the main device Bluetooth chip, the main device control chip will automatically enter the intermediate state (mode). In the intermediate state, the main device control chip is not allowed to send data to the main device Bluetooth chip. The main reasons include the following:

[0061] 1. Avoid conflicts. During the mode switching process, the second device may need to perform some specific operations to adapt to the new communication mode. If the first device sends other instructions at this time, it may conflict with the needs of the second device during the mode switching process, causing the second device to fail to respond correctly or perform incorrect operations.

[0062] 2. Ensure stability. Mode switching is a sensitive process that requires the second device to concentrate resources to complete. Prohibiting the issuance of instructions can reduce the amount of data that the second device needs to process during mode switching, ensuring the stability and success rate of the mode switching process.

[0063] 3. Preventing erroneous operations: During mode switching, the second device may not support certain device commands or may not be able to respond to these commands correctly. Prohibiting the issuance of commands can prevent the second device from making errors or malfunctions due to attempting to perform inappropriate operations.

[0064] 4. Resource management: When switching modes, the second device may need to reconfigure its Bluetooth stack and hardware resources. During this process, the second device may not be able to process new instructions, so prohibiting the issuance of instructions is to avoid wasting resources and possible problems.

[0065] S102, recording the initiation time of the mode switching request, and obtaining a target parameter value corresponding to a preset parameter currently used to affect communication quality, inputting the target parameter value into a pre-trained time determination model to perform a time prediction operation, and obtaining a predicted timeout waiting time.

[0066] It needs to be explained that since the main device Bluetooth chip of the second device or the first device may be affected by the network quality or system resources, there may be a certain time delay when sending request feedback information to the main device control chip of the first device. If the impact that may be caused by the time delay is ignored, it may be mistakenly believed that the request feedback information is sent abnormally at this time, which directly causes the main device control chip of the first device to be stuck in an intermediate state and unable to continue to control the second device.

[0067] For example, when the second device receives a mode switching request, or the master device Bluetooth chip of the first device forwards the request feedback information to the master device control chip of the first device, if the current network quality of the second device or the master device Bluetooth chip is poor, the second device or the master device Bluetooth chip will be unable to send data to the corresponding receiving end in time, while the data may actually be delivered in the next second. When the timeout waiting time is fixed, the above-mentioned situations will be judged as timeout sending, and may directly cause the master device control chip of the first device to be stuck in an intermediate state and unable to continue to control the second device.

[0068] For another example, when the second device receives a mode switching request, or the main device Bluetooth chip of the first device forwards the request feedback information to the main device control chip of the first device, the current network quality of the second device or the main device Bluetooth chip is good. Under normal circumstances, the second device or the main device Bluetooth chip can shorten the time to send data to the corresponding receiving end. When the timeout waiting time is fixed, even if the current network quality can meet the fast transmission of data, it is necessary to wait until the preset timeout waiting time is exceeded before it may be judged as a timeout transmission. In the traditional solution, when a timeout transmission is detected, an error will be reported to remind the user to restart the current first device. If the timeout waiting time is set to be long, the abnormal problem will be prolonged because it is not handled in time.

[0069] In summary, since setting the timeout waiting time too long or too short will bring adverse effects, in this embodiment, by obtaining the target parameter value corresponding to the preset parameter currently used to affect the communication quality when initiating a mode switching request to the second device, the target parameter value is input into the pre-trained time determination model to perform a time prediction operation, and the predicted timeout waiting time is obtained, so that the timeout waiting time is a result of dynamic adjustment, and a suitable value can be determined according to the actual usage scenario, thereby avoiding unnecessary negative effects caused by the timeout waiting time being set too long or too short.

[0070] S103: monitoring the execution result of the mode switching request.

[0071] It should be noted that if the master device Bluetooth chip of the first device fails to upload the success event or failure event sent by the second device to the master device control chip within the agreed time due to the device's own reasons or environmental interference, the connection state between the master device control chip and the master device Bluetooth chip will remain in an intermediate state, resulting in the inability of the subsequent device control chip to send any instructions to the master device Bluetooth chip. The most direct impact at this time is that the relevant Bluetooth remote control command cannot be sent to the second device through the first device, causing the first device to fail to control the second device. Therefore, in this embodiment, it is necessary to monitor the execution result of the mode switching request and perform corresponding operations according to the execution result.

[0072] S104: If the execution result is that no request feedback information is received within the timeout waiting time, the instruction issuing authority of the first device is revoked.

[0073] When the execution result is that the request feedback information returned by the second device is not received after the timeout waiting time, in order to avoid the connection state between the master device control chip and the master device Bluetooth chip being stuck in an intermediate state, resulting in the subsequent device control chip being unable to send any instructions to the master device Bluetooth chip. In this embodiment, by revoking the instruction sending authority of the master device control chip in the first device, conditions are created for the first device to re-initiate a mode switching request to the second device.

[0074] S105: Re-initiate a mode switching request to the second device.

[0075] In this embodiment, by re-initiating a mode switching request to the second device, the success rate of the mode switching is improved, and it is avoided that the first device stays in the intermediate state for a long time, resulting in the first device being unable to continue to control the second device.

[0076] At the same time, since the present solution obtains the target parameter value corresponding to the current preset parameter and redetermines the timeout waiting time each time it detects that no request feedback information is received after the timeout waiting time, it is possible to set the timeout waiting time to a smaller value when the timeout waiting time meets the downward adjustment requirements, so that the first device can promptly re-initiate a mode switching request to the second device, so that the second device can quickly respond to the mode switching request.

[0077] In some embodiments, Figure 2 As shown, before S101, the method further includes the following steps:

[0078] During the process of establishing a Bluetooth connection between the first device and the second device, a preset parameter value generated during each link management protocol interaction is obtained.

[0079] In this embodiment, the preset parameters refer to various parameters that can affect the communication quality, and may include but are not limited to the following parameters:

[0080] The device type of the second device, such as TV, mobile phone, speaker, headset, computer, etc.

[0081] The delay value is the average time of the first five times from the first device sending the link management protocol to the second device and then receiving the feedback information from the second device (preferably the average time corresponding to the five most recent times of sending the link management protocol is calculated).

[0082] Signal strength (RSSI) value.

[0083] The number of retransmissions, that is, the average number of retransmissions required by the first device from sending the link management protocol to hitting the second device in the first five times (preferably, the average number of times corresponding to the five most recent times of sending the link management protocol is calculated).

[0084] The initial time determination model is trained by using each of the preset parameter values ​​as a model training sample, and the model parameters of the initial time determination model are adjusted using a stochastic gradient descent algorithm until the loss function value of the initial time determination model exceeds a preset threshold, completing the model training and obtaining a pre-trained time determination model.

[0085] In this embodiment, the stochastic gradient descent (SGD) algorithm is used to train the model and change the parameters of the model. During the training process, the stochastic 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 at 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.

[0086] In some embodiments, Figure 2 As shown, after S103, the method further includes the following steps:

[0087] S1031: If the execution result is that the switching permission feedback information returned by the second device is received within the timeout waiting period, the current communication mode between the first device and the second device is switched to the breathing mode.

[0088] 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 information is received within the timeout waiting period, and it indicates that the agreement 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 can be switched to the breathing mode. It should be noted that the feedback information of allowing switching is specifically first uploaded to the main device Bluetooth chip of the first device, and then uploaded to the main device control chip of the first device by the main device Bluetooth chip.

[0089] S1032: If the execution result is that a rejection switching feedback information returned by the second device is received within the timeout waiting period, the current communication mode between the first device and the second device is not changed; and / or a prompt message containing the rejection switching feedback information is generated to prompt the user.

[0090] 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 information is received within the timeout waiting period, indicating that the second device rejects the mode switching request initiated by the first device, the current communication mode between the first device and the second device is maintained. It should be noted that the feedback information of rejecting switching is first uploaded to the main device Bluetooth chip of the first device, and then uploaded to the main device control chip of the first device by the main device Bluetooth chip.

[0091] In some other embodiments, a prompt message including feedback information of rejecting switching may be generated to prompt the user, for example, "the second device cannot be switched to the breathing mode temporarily because there are important files to be transferred."

[0092] In some embodiments, Figure 3 As shown, before S105, the method further includes the following steps:

[0093] S1041, obtaining the number of repetitions of the current mode switching request;

[0094] In this embodiment, since the first device repeatedly initiated the mode switching request many times but failed to receive the request feedback information within the timeout waiting period, it may be because there is a device abnormality or other unknown reasons in the first device or the second device. If the mode switching request continues to be repeatedly initiated to the second device indefinitely at this time, not only will it be impossible to prompt the user in time to take intervention measures to solve the current problem of being unable to control the second device normally, but it will also cause a waste of system resources.

[0095] S1042, determining whether the number of repeated initiations exceeds a preset number.

[0096] S1043: If the number of repeated initiations exceeds a preset number, stop initiating the mode switching request to the second device, and generate a device abnormality message to prompt the user.

[0097] In this embodiment, the number of repeated initiations can be set, for example three times. If the request feedback information cannot be received within the timeout waiting period after more than three times, the mode switching request to the second device is stopped, and a device abnormality message is generated to prompt the user. The user can try to repair it by restarting the device or disconnecting and reconnecting Bluetooth.

[0098] In some embodiments, Figure 4 As shown, before S101, the method further includes the following steps:

[0099] S1011, checking the role status of the first device in the current Bluetooth local area network, where the role status includes a central device or a peripheral device.

[0100] It needs to be explained that in Bluetooth technology, devices in a Bluetooth local area network are generally divided into two roles: central devices (Central) and peripheral devices (Peripheral), which is the basis of the Bluetooth low energy (BLE) communication mode.

[0101] Central: The central device is responsible for discovering and connecting to peripheral devices. In a Bluetooth LAN, the central device usually plays the role of a client, which can actively search for peripheral devices and establish connections with them. Once the connection is established, the central device can read or write the services and characteristics of the peripheral device.

[0102] Peripheral: A peripheral device provides services and characteristics that can be discovered and connected by a central device. In a Bluetooth LAN, a peripheral device usually plays the role of a server, broadcasting its existence and available services so that a central device can discover and interact with it.

[0103] S1012: If the role status of the first device is a central device, increase the initial polling interval between the first device and the second device without exceeding a preset maximum polling interval.

[0104] In this embodiment, when the first device initiates a mode switching request to the second device, it needs to first ensure that it is the central device in the current Bluetooth local area network, so that the first device has the authority to modify the polling interval. The polling interval refers to how often the first device sends a polling command to query the status or data of the second device to ensure that the first device and the second device can maintain a connection.

[0105] Allow the first device with the permission to modify the polling interval to increase the initial polling interval without exceeding the maximum polling interval, so that the first device and the second device can maintain a connection state without occupying too many system resources due to frequent polling operations, reducing the impact of the first device in the process of initiating a mode switching request to the second device, thereby improving the success rate of mode switching.

[0106] In some embodiments, Figure 4 As shown, after S1011, the method further includes the following steps:

[0107] S1013, if the role status of the first device is a peripheral device, initiate a role exchange request to the central device in the current Bluetooth local area network to change the role status of the first device to a central device, so that the first device has the right to modify the polling interval between the first device and the second device.

[0108] In this embodiment, since the first device needs to ensure that it is the central device in the Bluetooth local area network when initiating a mode switching request, it is necessary to initiate a role swap request to the central device in the current Bluetooth local area network when confirming that the first device is not currently the central device, that is, to initiate a master-slave role swap request, so that the first device has the authority to modify the polling interval.

[0109] S1014: Based on the modification authority, increase the initial polling interval between the first device and the second device without exceeding a preset maximum polling interval.

[0110] In this embodiment, the first device having the permission to modify the polling interval increases the initial polling interval without exceeding the maximum polling interval, so that the first device and the second device can maintain a connection without occupying too many system resources due to frequent polling operations, thereby reducing the impact of the first device in initiating a mode switching request to the second device, thereby improving the success rate of the mode switching.

[0111] As can be seen from the above, the communication mode switching method based on Bluetooth connection provided by the embodiment of the present application initiates a mode switching request to the second device when the trigger condition for turning on the breathing mode is detected, and freezes the instruction issuing authority of the first device; records the initiation time of the mode switching request, and obtains the target parameter value corresponding to the preset parameter currently used to affect the communication quality, and inputs the target parameter value into the pre-trained time determination model for time prediction operation to obtain the predicted timeout waiting time; monitors the execution result of the mode switching request; if the execution result is that the request feedback information is not received after the timeout waiting time, the instruction issuing authority of the first device is released, and the mode switching request is re-initiated to the second device. Using the communication mode switching method based on Bluetooth connection provided by the embodiment of the present application, by setting a reasonable timeout waiting time, if the first device does not receive the request feedback information sent by the second device within the timeout waiting time, the instruction issuing authority of the first device is released, and the mode switching request is re-initiated to the second device, so as to improve the success rate of the communication mode switching, and avoid the first device from being unable to control the second device normally due to the lack of instruction issuing authority. Moreover, the timeout waiting time is dynamically generated according to the current usage scenario, which can better meet the current usage scenario and avoid the problem that the first device fails to normally receive the request feedback information due to early or delayed re-initiating of the mode switching request to the second device.
