In the description of the embodiments herein, "/" means "or" unless otherwise specified, for example, a/B may mean a or B; "and/or" herein is merely an association describing an associated object, and means that there may be three relationships, e.g., a and/or B, which may mean: a exists alone, A and B exist simultaneously, and B exists alone.

In the following, the terms "first", "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the embodiments of the present application, "a plurality" means two or more unless otherwise specified.

Currently, in the development process of a bluetooth module, the quality of a bluetooth link is generally evaluated through the signal quality of the link, and the signal quality of the bluetooth link is generally detected through a log output method, for example, an electronic device may collect a log of each data reception, and a user may print the log and analyze the log, so as to obtain the signal quality of the bluetooth link. However, the above-mentioned manual printing method for detecting signal quality is complicated and inefficient.

Based on the above problem, the embodiment of the application provides a signal quality detection method, which can improve the efficiency of signal quality detection of a bluetooth module.

The signal quality detection method provided by the embodiment of the present application will now be described with reference to fig. 1 to 5. Fig. 1 is an application scenario of the embodiment of the present application. As shown in fig. 1, the application scenario includes a first bluetooth end 10, a second bluetooth end 20, and a second bluetooth end 21. For example, the first bluetooth end 10, the second bluetooth end 20, and the second bluetooth end 21 may be bluetooth chips, or may be electronic devices including the bluetooth chips. The embodiment of the present application does not specifically limit the specific forms of the first bluetooth end 10, the second bluetooth end 20, and the second bluetooth end 21 for executing the technical solution.

It should be noted that fig. 1 only shows the number of the second bluetooth terminals for example, and does not constitute a limitation to the embodiments of the present application, and in some embodiments, the number of the second bluetooth terminals may be greater or less, for example, the number of the second bluetooth terminals may be 1, and the number of the second bluetooth terminals may also be 3 or more.

Fig. 2 is a schematic diagram of a software structure of a first bluetooth end 10, and as shown in fig. 2, the first bluetooth end 10 includes a bluetooth protocol stack Host (Host, hereinafter, referred to as "Host" for convenience of description) 11 and a bluetooth protocol stack Controller (Controller, hereinafter, referred to as "Controller" for convenience of description) 12, and the Host 11 and the Controller 12 communicate with each other through a bluetooth Host and Controller Interface (HCI) 13. The host 11 is configured to receive user operations (e.g., turning on/off a signal quality acquisition function, setting a timer, deleting a signal quality report, and the like), and instruct the controller 12 to perform corresponding tasks; the controller 12 is configured to receive a data packet sent by a peer device (e.g., a second bluetooth peer), generate a signal quality report according to the receiving condition of the data packet, and send the signal quality report to the host 11.

Next, taking the first bluetooth peer 10 and the second bluetooth peer 20 as an example for explanation, the first bluetooth peer 10 and the second bluetooth peer 20 have established a communication connection, and the second bluetooth peer 20 sends a data packet to the first bluetooth peer 10. Fig. 3 is a schematic flowchart of an embodiment of a signal quality detection method according to an embodiment of the present application, where the signal quality detection method includes:

in step 301, the user configures the signal quality acquiring state of the first bluetooth end 10 to be an enabling state.

Specifically, the user may configure the signal quality acquisition state in the first bluetooth terminal 10 by the HCI command, so that the signal quality acquisition state is configured as an enabled state. The signal quality acquisition state may include an enable state and a disable state. The enabled state may be used to indicate that the signal quality acquiring function is turned on, that is, when the signal quality acquiring state is the enabled state, the first bluetooth end 10 may perform signal quality detection, so as to output a signal quality report; the disabled state may be used to characterize that the signal quality acquisition function is disabled, that is, when the signal quality acquisition state is the disabled state, the first bluetooth end 10 may stop performing signal quality detection, so as to prohibit outputting a signal quality report.

In step 302, the first bluetooth end 10 outputs a signal quality report based on the receiving status of the received data packet.

Specifically, the data packet may be sent by the second bluetooth end 20. The receiving status of the data packet includes correct receiving and wrong receiving. The types of the erroneous reception may include: CRC check error, synchronization error, reception time error, or reception length error, etc. For example, if the first bluetooth peer 10 successfully receives the data packet sent by the second bluetooth peer 20, the receiving status of the data packet is correct. When the first bluetooth peer 10 receives the data packet transmitted by the second bluetooth peer 20, errors such as CRC check error, synchronization error, reception time error, and reception length error occur, and the reception status of the data packet is an erroneous reception.

In a specific implementation, the first bluetooth peer 10 may generate and output a signal quality report based on the received reception status of the data packet sent by the second bluetooth peer 20, where the signal quality report may include the reception status of one or more data packets. Therefore, the signal quality report can be automatically generated, the detection of the signal quality of the Bluetooth link is completed, and the efficiency of signal quality detection is improved.

The first bluetooth end 10 and the second bluetooth end 20 are taken as an example for description, and the first bluetooth end 10, the second bluetooth end 20 and the second bluetooth end 21 are taken as an example for description. Fig. 4 is a schematic flowchart of another embodiment of a signal quality detection method provided in the present application. Fig. 5 is a timing diagram of an embodiment of the signal quality detection method provided in the present application, and in order to facilitate the public to fully understand the complete scheme of the present application, the steps that the first bluetooth end and the second bluetooth end need to perform at different stages are integrated into the description of the flow according to a timeline, but it should be understood that, for the first bluetooth end 10 that performs signal quality detection, only those steps that need to be performed in the flow need to be performed in the signal quality detection process:

step 501, the first bluetooth end 10 establishes a connection with the second bluetooth end 20 and the second bluetooth end 21, and the first bluetooth end 10 starts a signal quality obtaining function.

Specifically, the first bluetooth end 10 may start a signal quality obtaining function of one or more links, where the signal quality obtaining function is configured to obtain a receiving status of a received data packet on the link, where the receiving status of the received data packet may be used to generate a signal quality report, and the information quality report may be used to evaluate the signal quality of the link. Wherein the link may comprise a communication link between the first device and the second device. For example, a first link may be between the first bluetooth end 10 and the second bluetooth end 20, and a second link may be between the first bluetooth end 10 and the second bluetooth end 21. In a specific implementation, the user may open the signal quality acquisition function of the first link and/or the second link in the first bluetooth end 10 through an HCI command, so that the controller 12 in the first bluetooth end 10 is in an enable state for signal quality acquisition.

For example, the user may click a switch for turning on the signal quality acquisition function in the operation interface of the first bluetooth terminal 10. In response to the user's operation, the host 11 in the first bluetooth end 10 sends a turn-on instruction to the controller 12, instructing the controller 12 to turn on a signal quality acquisition function corresponding to the link. Wherein the open command may be an HCI command, and the open command may include a link ID for identifying a link between the first bluetooth peer 10 and the

second bluetooth peer

20 or 21. After receiving the start instruction of the host 11, the controller 12 in the first bluetooth end 10 may start the signal quality obtaining function corresponding to the link ID according to the link ID in the start instruction.

It is to be understood that the user may turn on the signal quality acquisition function of a part of the links, for example, only turn on the signal quality acquisition function of the first link or the second link. The user may also turn on the signal quality acquisition functions of all links, for example, simultaneously turning on the signal quality acquisition functions of the first link and the second link. The number of links for starting the signal quality acquisition function is not particularly limited in the embodiment of the present application.

Alternatively, the user may disable the signal quality acquisition function of one or more links, so that the controller 12 in the first bluetooth end 10 is in a disabled state for signal quality acquisition. When the controller 12 in the first bluetooth terminal 10 is in the disabled state for signal quality acquisition, it may stop outputting the signal quality report based on the reception state of the received data packet.

In step 502, the first bluetooth end 10 configures a time interval for signal quality reporting.

Specifically, the first bluetooth peer 10 may configure the time interval of the signal quality report of the link, and for example, the configuration of the time interval of the signal quality report may be performed through a configuration port of the first bluetooth peer 10, for example, a configuration port such as I2C or SPI. In a specific implementation, the user may set a timer in the operation interface of the first bluetooth end 10, where the timer is used to time the time interval of the signal quality report. Further, the timer may correspond to each link, and may be associated with a link ID, for example. In response to the operation of setting the timer by the user, the host 11 in the first bluetooth end 10 may send a timing report instruction to the controller 12, instructing the controller 12 to set the timer. The timed reporting instruction may include a link ID and a time interval. After receiving the timing report command from the host 11, the controller 12 in the first bluetooth end 10 may set a timer corresponding to the link ID according to the link ID in the timing report command, where a time value of the timer may be determined by a time interval in the timing report command. Preferably, the time interval may be set in the order of milliseconds, for example, the time interval is N milliseconds, where N is a positive integer. It is to be understood that the above example only illustrates a scenario in which the time interval is in milliseconds, and does not constitute a limitation to the embodiments of the present application, and in some embodiments, the time interval may be a time length in other units.

Optionally, the first bluetooth peer 10 may also configure a default signal quality reporting time interval, for example, in a case that the user does not configure the signal quality reporting time interval, the first bluetooth peer 10 may have the default signal quality reporting time interval.

Step 503, determining whether to start timing the time interval of the signal quality report based on the state of signal quality acquisition.

Specifically, after the user completes the time interval configuration for the signal quality report, the first bluetooth end 10 may start timing the time interval of the signal quality report.

Before the first bluetooth end 10 starts timing the time interval of the signal quality report, it can also determine the state of signal quality acquisition.

If the signal quality acquisition state is enabled, the controller 12 in the first bluetooth end 10 may initialize a timer task and start timing, and the cumulative timing duration of the timer may be determined by the time interval of the signal quality report.

If the signal quality acquisition state is in the disabled state, the controller 12 in the first bluetooth end 10 may feed back a failure message to the host 11, where the failure message is used to notify the host 11 that the timer starts to count time unsuccessfully, that is, at this time, the timer task is not initialized, and the timer task is not counted time. In a specific implementation, the failure message may further include a failure reason, which may be, for example, "the state of the current signal quality acquisition is in a disabled state".

Optionally, the timer task may be configured to generate a signal quality report, and the task generating the signal quality report may be configured with a first scheduling priority in advance; the first scheduling priority is used to characterize the scheduling order of tasks that generate signal quality reports. In a specific implementation, since a user may configure a timer task for each link, the timer task for each link may configure an independent scheduling priority, for example, each link ID may be bound to a separate first scheduling priority; all links may also include the same first scheduling priority, for example, all link IDs correspond to the same first scheduling priority, which is not particularly limited in the embodiment of the present application.

Table 1 exemplarily shows a mapping relationship of the link and the timer task between the first bluetooth end 10 and the

second bluetooth end

20 and 21.

TABLE 1

In step 504, the first bluetooth peer 10 receives the data packet sent by the second bluetooth peer 20 and/or the second bluetooth peer 21, and obtains the signal quality data based on the receiving condition of the data packet.

Specifically, after the first bluetooth peer 10 starts the timer task, if the state of the signal quality acquisition is in the enabled state, the first bluetooth peer 10 may receive the data packet sent by the second bluetooth peer 20 and/or the second bluetooth peer 21 within the time interval of the signal quality report. When the first bluetooth peer 10 receives any one of the data packets of the second bluetooth peer 20 and/or the second bluetooth peer 21, the receiving status of the data packet can be obtained. Illustratively, the receiving state of the data packet may include: correct reception, CRC check error, synchronization error, reception time error, and reception length error. Then, the first bluetooth end 10 can also store the receiving status of each data packet. In a specific implementation, after the controller 12 in the first bluetooth end 10 starts the timer task, if the state of signal quality acquisition is in an enable state, the controller 12 in the first bluetooth end 10 may receive the data packets sent by the second bluetooth end 20 and/or the second bluetooth end 21, acquire the receiving state of each data packet, and store the receiving state of each data packet in a buffer of the controller 12. The receiving status of each data packet may correspond to a link ID, for example, a data packet received by the controller 12 from the second bluetooth end 20 corresponds to the first link, and a data packet received by the controller 12 from the second bluetooth end 21 corresponds to the second link.

It will be appreciated that the above-described reception status for each packet may be considered signal quality data. Illustratively, if the data packet is correctly received, that is, the receiving status of the data packet is correctly received, it indicates that the current channel condition is better. If the CRC error, the synchronization error, the reception time error, and the reception length error occur, that is, the reception status of the data packet is the CRC error, the synchronization error, the reception time error, or the reception length error, the channel condition is poor. When the first bluetooth end 10 acquires the receiving statuses of the plurality of data packets within a certain period of time (for example, the time interval of the signal quality report), a corresponding signal quality report may be generated, and the signal quality report may include the receiving statuses of the plurality of data packets.

Optionally, when the signal quality acquiring state is in the enabling state, the first bluetooth peer 10 may further actively send a data request to the second bluetooth peer 20 and/or the second bluetooth peer 21, where the data request may be used to request the second bluetooth peer 20 and/or the second bluetooth peer 21 to send a data packet to the first bluetooth peer 10, so that the first bluetooth peer 10 may acquire the receiving state of the data packet, and further may generate a signal quality report according to the receiving state of the received data packet.

In step 505, the first bluetooth end 10 generates a signal quality report based on the signal quality data.

Specifically, the first bluetooth terminal 10 may generate the signal quality report in the following two scenarios.

Scene 1:

after the timer task is started, if the timer is overtime, the first bluetooth end 10 may generate a corresponding signal quality report based on the signal quality data stored in the time interval of the signal quality report. The signal quality report may include a reception status of a plurality of data packets received within a time interval of the signal quality report. It will be appreciated that each signal quality data may include an ID of the packet and a receipt status of the packet. Further, since each packet is transmitted by the link corresponding to the link ID, each signal quality report may correspond to the link ID.

Table 2 exemplarily shows a format of the signal quality report of the first link.

TABLE 2

As shown in table 2, the signal quality report may include a link ID and signal quality data corresponding to the link ID. The link ID is used to characterize which link the signal quality report corresponds to. The signal quality data may include a packet ID and a reception status corresponding to the packet ID.

It is to be understood that table 2 above only illustrates the signal quality report of one link by way of example, and does not limit the embodiments of the present application.

Table 3 exemplarily shows formats of signal quality reports of the first link and the second link.

TABLE 3

In a specific implementation, the controller 12 in the first bluetooth end 10 may monitor the timer of each link in real time. When the controller 12 monitors that the timer of any link times out, it may generate a corresponding signal quality report based on the signal quality data corresponding to the link stored in the time interval of the signal quality report, and may output the signal quality report.

Optionally, after monitoring that the timer of any link times out, the first bluetooth end 10 may further detect whether a data communication task exists in the link at the current time, where the data communication task may be, for example, a data sending task or a data receiving task. It is to be understood that the data communication task is only an exemplary scenario illustrating data transmission and data reception, and does not constitute a limitation to the embodiments of the present application, and in some embodiments, the data communication task may be other types of tasks.

If a data communication task exists at the current moment of the link, a second scheduling priority of the data communication task may be obtained, and the second scheduling priority of the data communication task may be compared with the first scheduling priority of the task for generating a signal quality report, and if the second scheduling priority of the data communication task is lower than the first scheduling priority of the task for generating a signal quality report, the first bluetooth end 10 may generate a corresponding signal quality report based on the signal quality data corresponding to the link stored in the time interval of the signal quality report, and may output the signal quality report, for example, the data communication task may be further executed after being displayed on a display screen of the first bluetooth end 10; if the second scheduling priority of the data communication task is higher than the first scheduling priority of the task for generating the signal quality report, the first bluetooth peer 10 may process the data communication task first, and after the data communication task is completed, the first bluetooth peer 10 may further detect whether there is a data communication task, and if there is no data communication task, may generate a corresponding signal quality report based on the signal quality data corresponding to the link stored in the time interval of the signal quality report, and may output the signal quality report.

If there is no data communication task at the current time of the link, the first bluetooth end 10 may generate a corresponding signal quality report based on the signal quality data corresponding to the link stored in the time interval of the signal quality report, and may output the signal quality report.

Scene 2:

the user can operate on the operation interface of the first bluetooth end 10 to trigger the first bluetooth end 10 to actively generate the signal quality report. For example, the user may click on a signal quality report generation button on the operation interface of the first bluetooth terminal 10. In response to the user's operation, the host 11 in the first bluetooth terminal 10 transmits a signal quality report output request for instructing the controller 12 to output a signal quality report to the controller 12. Wherein the signal quality report output request may include a link ID. When the controller 12 receives a signal quality report output request from the host 11, it may acquire, based on the link ID in the signal quality report output request, signal quality data corresponding to the link ID that has been stored before the signal quality report output request was received, and may generate a corresponding signal quality report based on the signal quality data that has been stored before the signal quality report output request was received. The signal quality report may be output when the controller 12 generates a signal quality report corresponding to the link ID.

Alternatively, when the controller 12 receives a signal quality report output request transmitted by the host 11, it may also detect the state of signal quality acquisition of the link corresponding to the link ID.

If the signal quality acquisition state of the link corresponding to the link ID is enabled, the controller 12 may acquire, based on the link ID in the signal quality report output request, signal quality data corresponding to the link ID that has been stored before the signal quality report output request was received, generate a corresponding signal quality report based on the signal quality data that has been stored before the signal quality report output request was received, and output the signal quality report.

If the signal quality acquisition status of the link corresponding to the link ID is in the disabled status, the controller 12 may return a failure message to the host 11, where the failure message is used to notify the host 11 that the signal quality report output fails.

In step 506, the first bluetooth end 10 updates the communication information of the link based on the signal quality report.

Optionally, after acquiring the signal quality report of any link, the first bluetooth end 10 may obtain the signal quality of the link based on the status information of the data packet in the signal quality report of the link, and may update the communication information of the link based on the signal quality of the link. The communication information may include a frequency band table and a physical layer communication rate corresponding to the link, the frequency band table may include a plurality of selectable frequency bands, and the selectable frequency bands may be used for communication between the first bluetooth end and the second bluetooth end.

In a specific implementation, after the first bluetooth end 10 generates a signal quality report of any link, the state information of the data packet in the signal quality report of the link may be obtained, and the state information of the data packet of the link may be counted based on a preset rule, so that the signal quality of the link may be obtained. For example, the preset rule may be: the total number of correctly received data packets can be counted in the state information of the data packets, a correct receiving rate can be obtained based on the total number of the correctly received data packets, the correct receiving rate is compared with a preset threshold value, and if the correct receiving rate is greater than or equal to the preset threshold value, the signal quality of the link is better; if the correct receiving rate is less than the predetermined threshold, the signal quality of the link is poor. It is to be understood that the above examples only illustrate the preset rule of the correct receiving rate, and do not limit the embodiments of the present application, and in some embodiments, the preset rule may also determine the signal quality through other rules.

Then, if the first bluetooth end 10 determines that the signal quality of the link is better, the current frequency band table and the physical layer communication rate can be maintained.

If the first bluetooth end 10 determines that the signal quality of the link is poor, the frequency band table and the frequency band currently used for communication of the link may be obtained. The current frequency band is determined by the selectable frequency bands, for example, the current frequency band may be selected from the selectable frequency bands based on a predetermined rule. The specific selection rule may refer to the bluetooth protocol, which is not described herein again. Then, the first bluetooth end 10 may delete the current frequency band from the frequency band table, so as to update the frequency band table. In addition, the first bluetooth peer 10 may also update the communication rate of the physical layer, for example, the first bluetooth peer 10 may switch from the current physical layer communication rate to another physical layer communication rate, so that the communication between the first bluetooth peer and the second bluetooth peer may be more stable and reliable, where the current physical layer communication rate and the another physical layer communication rate may be the physical layer communication rate supported between the first bluetooth peer 10 and the second bluetooth peer 20 or the second bluetooth peer 21.

In step 507, in response to the deletion operation of the user, the first bluetooth end 10 deletes the signal quality data.

Optionally, the user may also operate on the operation interface of the first bluetooth end 10 to delete the signal quality data of any one or more links stored in the first bluetooth end 10. For example, the user may click a signal quality data deletion button on the operation interface of the first bluetooth terminal 10. In response to the deletion operation by the user, the host 11 in the first bluetooth end 10 sends a deletion instruction to the controller 12, the deletion instruction being used to instruct the controller 12 to delete the corresponding signal quality data. Wherein the delete instruction may include the link ID. When the controller 12 receives the deletion instruction sent by the host 11, the stored signal quality data of the link corresponding to the link ID can be deleted based on the link ID in the deletion instruction, thereby saving the memory.

Step 508, in response to the adjustment operation of the user, adjusting the time interval of the signal quality report.

Optionally, in a specific implementation, when a user configures a time interval of a signal quality report of the link for the first time, the time interval of the signal quality report of the link may be set to be shorter, so that the output of the signal quality report may be triggered as soon as possible, and further, the signal quality of the bluetooth link may be obtained quickly. After the signal quality report is obtained, if the user determines that the current signal quality of the bluetooth link is better through analysis of the signal quality report, for example, the current signal quality of the bluetooth link is higher than a preset threshold, the user may increase the value of the time interval of the signal quality report, so that the frequency of outputting the signal quality report by the first bluetooth end 10 may be reduced, and further, resources may be saved, and power consumption may be reduced. For example, the user may reconfigure the time interval of the signal quality report, and the time interval of the reconfigured signal quality report may be longer than the time interval of the signal quality report before the reconfiguration. After the time interval of the signal quality report is reconfigured, the first bluetooth end 10 may initialize a new timer according to the time interval of the reconfigured signal quality report, start timing, and output a signal quality report based on a receiving state of a packet received within the time interval of the reconfigured signal quality report after the new timer expires. The accumulated time duration of the new timer may be the time interval of the reconfigured signal quality report.
