[0040] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0041] It should be noted that all the actions of obtaining signals, information or data in the present disclosure are performed in compliance with the corresponding data protection regulations and policies of the country where the device is located, and with the authorization given by the corresponding device owner.

[0042] Figure 1 is a flow chart of a channel interference detection method according to an embodiment of the present disclosure. As shown in Figure 1, the channel interference detection method can include steps S11 and S12.

[0043] In step S11, the idle time of Bluetooth transmission is determined.

[0044] The Bluetooth transmission includes Bluetooth sending and Bluetooth receiving.

[0045] Figure 2 shows a schematic diagram of Bluetooth transmission according to an embodiment of the present disclosure, in which the number 1 represents the sending time of the Bluetooth device, i.e. the Bluetooth device is in the sending state, the number 2 represents the receiving time of the Bluetooth device, i.e. the Bluetooth device is in the receiving state, and the number 3 represents the idle time of the Bluetooth transmission, i.e. the Bluetooth device is in the idle state without sending or receiving. For example, the Bluetooth device transceiver switching period, no Bluetooth transmission period, etc. all belong to the idle time of the Bluetooth transmission.

[0046] In step S12, the interference existing in the Bluetooth channel is detected during the idle time to obtain the interference evaluation value of each Bluetooth channel.

[0047] In some embodiments, the existing Bluetooth hardware resources can be used to detect the interference existing in the Bluetooth channel. In this way, on the one hand, the cost of interference detection can be saved, and on the other hand, since the interference detection is performed during the idle time of the Bluetooth transmission, the use of the existing Bluetooth hardware resources will not affect the normal transmission of the Bluetooth.

[0048] By using the above technical solution, the idle time of the Bluetooth transmission is first determined, and then the interference existing in the Bluetooth channel is detected during the idle time to obtain the interference evaluation value of each Bluetooth channel. Therefore, since the interference existing in the Bluetooth channel is detected during the idle time of the Bluetooth transmission, on the one hand, the interference existing in the Bluetooth channel can be accurately evaluated, and on the other hand, since the normal transmission time of the Bluetooth is not occupied, the normal transmission (e.g. receiving, sending, etc.) of the Bluetooth will not be affected.

[0049] Figure 3 shows a flowchart of detecting the interference existing in the Bluetooth channel during the idle time of the Bluetooth transmission to obtain the interference evaluation value of each Bluetooth channel according to an embodiment of the present disclosure. As shown in Figure 3, the flowchart includes steps S121 and S122.

[0050] In step S121, interference existing in the adjacent N Bluetooth channels is detected during each idle time of Bluetooth transmission, where N is a positive integer greater than or equal to 3.

[0051] Since the idle time of Bluetooth transmission is limited, interference detection of all Bluetooth channels cannot be completed in one idle time, therefore, the present application detects interference existing in the adjacent N Bluetooth channels during one idle time, and through multiple idle times, interference detection of all Bluetooth channels is completed.

[0052] In step S122, interference evaluation value of each Bluetooth channel is determined based on the interference detection value of each Bluetooth channel and its adjacent Bluetooth channels before and after it.

[0053] For example, N equals 4, and interference detection is performed on the adjacent m+1 Bluetooth channel, m+2 Bluetooth channel, m+3 Bluetooth channel, and m+4 Bluetooth channel during the current idle time, then interference evaluation value of the m+2 Bluetooth channel can be determined based on the interference detection value of the m+2 Bluetooth channel and its adjacent Bluetooth channels before and after it (i.e. m+1 Bluetooth channel and m+3 Bluetooth channel), interference evaluation value of the m+3 Bluetooth channel can be determined based on the interference detection value of the m+3 Bluetooth channel and its adjacent Bluetooth channels before and after it (i.e. m+2 Bluetooth channel and m+4 Bluetooth channel), and since the m+1 Bluetooth channel only has the adjacent Bluetooth channel after it (i.e. m+2 Bluetooth channel) and the m+4 Bluetooth channel only has the adjacent Bluetooth channel before it (i.e. m+3 Bluetooth channel) among the Bluetooth channels detected by interference during the current idle time, interference evaluation value of the m+1 Bluetooth channel and the m+4 Bluetooth channel cannot be obtained by the current interference detection, and interference evaluation value of the m+1 Bluetooth channel and the m+4 Bluetooth channel will be detected during other idle time when the m+1 Bluetooth channel and the m+4 Bluetooth channel each have adjacent Bluetooth channels before and after it. Since when a Bluetooth channel is detected by interference, if the Bluetooth channel is interfered by wifi or Bluetooth, the interference detection value obtained is relatively large, for wifi interference, the Bluetooth channel is expected to be a channel interfered, but for Bluetooth interference, since Bluetooth transmission is in different Bluetooth channels each time, the Bluetooth channel is not a channel interfered or at least is not a channel frequently interfered, and through the interference detection method according to the embodiments of the present application, since interference evaluation value of each Bluetooth channel is determined based on the interference detection value of each Bluetooth channel and its adjacent Bluetooth channels before and after it, the above-mentioned situation can be identified, thereby ensuring the accuracy of interference detection.

[0054] In addition, taking the BLE Bluetooth channel as an example, the BLE Bluetooth channel 0 has no previous adjacent BLE Bluetooth channel, and the BLE Bluetooth channel 39 has no subsequent adjacent BLE Bluetooth channel, so the interference evaluation value of the BLE Bluetooth channel 0 and the BLE Bluetooth channel 39 cannot be obtained by using the method described in the foregoing based on the previous and subsequent adjacent Bluetooth channels.

[0055] Generally, the interference existing in the BLE Bluetooth channel 0 is lower than the interference existing in the BLE Bluetooth channel 1, and the interference existing in the BLE Bluetooth channel 39 is lower than the interference existing in the BLE Bluetooth channel 38. Therefore, the interference evaluation value of the BLE Bluetooth channel 0 can be obtained by subtracting a coefficient from the interference evaluation value of the BLE Bluetooth channel 1, and the interference evaluation value of the BLE Bluetooth channel 39 can be obtained by subtracting a coefficient from the interference evaluation value of the BLE Bluetooth channel 38. The specific value of the subtracted coefficient can be obtained according to experience or by measurement.

[0056] By using the technical solution described above, since the interference evaluation value of each Bluetooth channel can be determined based on the interference detection values of each Bluetooth channel and the previous and subsequent adjacent Bluetooth channels of the Bluetooth channel, the accuracy of the Bluetooth channel interference detection is ensured.

[0057] In some embodiments, the step of determining the interference evaluation value of each Bluetooth channel based on the interference detection values of each Bluetooth channel and the previous and subsequent adjacent Bluetooth channels of the Bluetooth channel in the N Bluetooth channels in the step S122 can include: if the difference between the interference detection values of a certain Bluetooth channel and the previous and subsequent adjacent Bluetooth channels of the Bluetooth channel in the N Bluetooth channels is less than a first threshold value, increasing the interference detection value of the Bluetooth channel to obtain the interference evaluation value of the Bluetooth channel.

[0058] For example, during an idle time, the interference detection values of the Bluetooth channel Chn(k) and the previous and subsequent adjacent Bluetooth channels Chn(k-1) and Chn(k+1) are N(k), N(k-1) and N(k+1) respectively. Then, if the difference between N(k) and N(k-1) is less than a first threshold value and the difference between N(k) and N(k+1) is less than a first threshold value, it indicates that the values of N(k-1), N(k) and N(k+1) are relatively small, so the interference detection value N(k) of the Bluetooth channel Chn(k) can be increased by a coefficient to increase N(k) to obtain the interference evaluation value of the Bluetooth channel Chn(k).

[0059] Through the above processing mode, the following cases can be covered, so that the interference detection of the Bluetooth channel is more accurate: for the interference of wifi, when the wifi interference covers the three adjacent Bluetooth channels Chn(k-1), Chn(k) and Chn(k+1), the interference detection values of the three Bluetooth channels are not much different; when the wifi interference does not completely cover the three Bluetooth channels, the interference detection values of the three Bluetooth channels will be quite different; for the interference of Bluetooth transmission, if the Bluetooth interference transmission is in the Bluetooth channel Chn(k), the interference detection value N(k) will be much larger than the interference detection values N(k-1) and N(k+1).

[0060] In some embodiments, the determining, in step S122, of the interference evaluation value of each of the Bluetooth channels based on the interference detection values of each of the Bluetooth channels and its adjacent Bluetooth channels before and after the Bluetooth channel can include: if the difference between the interference detection values of a certain Bluetooth channel and its adjacent Bluetooth channels before and after the Bluetooth channel is greater than a second threshold value, reducing the interference detection value of the Bluetooth channel to obtain the interference evaluation value of the Bluetooth channel. The second threshold value is preferably greater than the first threshold value.

[0061] For example, during an idle time, for the Bluetooth channel Chn(k) and its adjacent Bluetooth channels Chn(k-1) and Chn(k+1) before and after the Bluetooth channel, the interference detection values obtained are N(k), N(k-1) and N(k+1) respectively. Then, if the difference between N(k) and N(k-1) is greater than the second threshold value and the difference between N(k) and N(k+1) is greater than the second threshold value, it indicates that the values of N(k-1), N(k) and N(k+1) are quite different, so the interference detection value N(k) of the Bluetooth channel Chn(k) can be reduced by a coefficient, so that N(k) is reduced, thereby obtaining the interference evaluation value of the Bluetooth channel Chn(k).

[0062] In some embodiments, the reducing the interference detection value of the Bluetooth channel to obtain the interference evaluation value of the Bluetooth channel can include: determining the reduction amount according to the sizes of the interference detection values of the Bluetooth channel and its adjacent Bluetooth channels before and after the Bluetooth channel, and the sizes of the differences between the interference detection values of the Bluetooth channel and its adjacent Bluetooth channels before and after the Bluetooth channel; and reducing the interference detection value of the Bluetooth channel based on the determined reduction amount to obtain the interference evaluation value of the Bluetooth channel, for example, subtracting the determined reduction amount from the interference detection value of the Bluetooth channel to obtain the interference evaluation value of the Bluetooth channel. Since the sizes of the interference detection values of the Bluetooth channel and its adjacent Bluetooth channels before and after the Bluetooth channel, and the sizes of the differences between the interference detection values of the Bluetooth channel and its adjacent Bluetooth channels before and after the Bluetooth channel are considered when determining the reduction amount, the determined reduction amount is more accurate, and the interference evaluation value of the Bluetooth channel is more accurate.

[0063] Through the above processing mode, the following cases can be covered to make the interference detection of the Bluetooth channel more accurate: for the interference of wifi, when the wifi interference covers the three adjacent Bluetooth channels Chn(k-1), Chn(k) and Chn(k+1), the interference detection values of the three Bluetooth channels are not much different; when the wifi interference does not completely cover the three Bluetooth channels, the interference detection values of the three Bluetooth channels will be quite different; for the interference of Bluetooth transmission, if the Bluetooth interference transmission is in the Bluetooth channel Chn(k), the interference detection value N(k) will be much larger than the interference detection values N(k-1) and N(k+1).

[0064] In some embodiments, the channel interference detection method according to the embodiments of the present disclosure can further include: for each of the Bluetooth channels, taking the maximum interference evaluation value of the Bluetooth channel in the latest preset time period as the final interference evaluation value of the Bluetooth channel.

[0065] Since the time of interference is uncertain, if there is a wifi interference in a Bluetooth channel, but when the interference detection of the Bluetooth channel is performed, the wifi is not transmitting, it will be detected that the Bluetooth channel has no interference, and thus an interference Bluetooth channel is mistakenly evaluated as a non-interference Bluetooth channel.

[0066] To solve this misjudgment situation, the channel interference detection method according to the embodiments of the present disclosure records interference detection results for a period of time, and takes the maximum interference evaluation value in a period of time as the final interference evaluation value of the Bluetooth channel.

[0067] For example, interference detection is performed on all Bluetooth channels once per time period T1, and the interference evaluation values of all Bluetooth channels are obtained and recorded as R1 (containing the interference evaluation values of all Bluetooth channels). Interference detection is performed on all Bluetooth channels in the next time period to obtain interference evaluation values, which are recorded as R2. This is repeated, and K consecutive record values are continuously saved. When the interference of all current Bluetooth channels is needed, the interference evaluation values of the current time and the previous K times are taken as the basis data. For a single Bluetooth channel, the maximum interference evaluation value of the K interference evaluation values of the Bluetooth channel is taken as the final interference evaluation value of the Bluetooth channel. Each Bluetooth channel is valued in this way to obtain a maximum value set Rmax of the K interference detection interference evaluation values of each Bluetooth channel. The values in the Rmax set can be arranged in order from small to large, and the smaller the value, the smaller the interference of the Bluetooth channel. When a Bluetooth channel is needed, the Bluetooth channel with no interference or small interference can be selected from the sorted Rmax set for Bluetooth transmission, so that the Bluetooth transmission is smoother.

[0068] By adopting the technical scheme, the interference detection result of the Bluetooth channel can be more accurate, and the interference misjudgment can be avoided, since the maximum interference evaluation value of the Bluetooth channel in the latest preset time period can be taken as the final interference evaluation value of the Bluetooth channel for each Bluetooth channel.

[0069] In some embodiments, the Bluetooth channel interference detection method according to the embodiments of the present disclosure can further include: performing interference detection on all the Bluetooth channels once every preset time interval.

[0070] For example, interference detection is performed on N adjacent Bluetooth channels once in an idle time, and a total of M consecutive idle times are needed to complete interference detection on all the Bluetooth channels. After completing interference detection on all the Bluetooth channels, the next interference detection on all the Bluetooth channels is started after a preset time interval.

[0071] By adopting the technical scheme, interference detection is performed on all the Bluetooth channels once every preset time interval, that is, all the Bluetooth channels are periodically detected, all the Bluetooth channels are detected once every preset time interval, and interference detection is performed in the idle time of Bluetooth transmission, so that the normal transmission (for example, reception and transmission) of Bluetooth is not affected.

[0072] FIG. 4 shows a Bluetooth channel interference timing diagram according to an embodiment of the present disclosure.

[0073] In FIG. 4, the vertical axis is the channel, and the horizontal axis is the time. FIG. 4 shows a total of 40 BLE Bluetooth channels from channel 0 to channel 39. In FIG. 4, the pattern-filled part represents the interference of wifi on the Bluetooth channel, and the wifi transmission occupies multiple Bluetooth channels (for example, 20MHz or 40Mhz bandwidth, occupying 10 or 20 Bluetooth channels), and each wifi transmission has different time length. In FIG. 4, the solid color-filled part represents Bluetooth transmission, and each Bluetooth transmission occupies one BLE Bluetooth channel (for example, 2MHz bandwidth) or only half of a BLE Bluetooth channel (for example, 1MHz bandwidth), and Bluetooth jumps to each Bluetooth channel for each transmission.

[0074] Whether it is wifi interference or Bluetooth interference, the time of each interference is different. As shown in FIG. 4, it is expected to evaluate the Bluetooth channels outside the dashed line frame as interference channels. The interference channel refers to the Bluetooth channel in which interference exists. By adopting the channel interference detection method according to the embodiments of the present disclosure, the channel interference in FIG. 4 can be accurately detected, for example, it can be accurately detected that the interference existing in the Bluetooth channels outside the dashed line frame is larger, and the interference existing in the Bluetooth channels inside the dashed line frame is smaller or no interference.

[0076] By using the above technical solution, the idle time of Bluetooth transmission is determined first, and then the interference existing in the Bluetooth channels is detected during the idle time to obtain the interference evaluation value of each of the Bluetooth channels. Therefore, since the interference existing in the Bluetooth channels is detected during the idle time of Bluetooth transmission, on the one hand, the interference existing in the Bluetooth channels can be accurately evaluated, and on the other hand, since the normal transmission time of Bluetooth is not occupied, the normal transmission (e.g., reception, transmission, etc.) of Bluetooth will not be affected.
