The terminal equipment includes a Bluetooth module, and the Bluetooth module includes a Bluetooth host (host) module and a Bluetooth controller (controller). ) module, and other modules may also be included in the terminal equipment, which will not be specifically introduced here.

The method of this embodiment is a method performed by other modules of the terminal device, and the flow chart is shown in Figure 2, including:

Step 101, the Bluetooth module of the terminal device performs a Bluetooth connection with a Bluetooth headset or a Bluetooth vehicle, specifically, a Bluetooth connection between a Bluetooth control module in the Bluetooth module and a Bluetooth headset or a Bluetooth vehicle.

Step 102, in the process that the bluetooth module of the terminal device sends the played audio data to the bluetooth headset or the bluetooth vehicle through the bluetooth connection, determine whether the time interval for the bluetooth host module to send the bluetooth format audio data to the bluetooth control module is greater than the preset time interval If the time value is greater than, then execute steps 103 and 104, if not, then end the process.

It can be understood that when the terminal device is connected to the Bluetooth headset or the Bluetooth car, it will obtain the audio data in the original format that is being played, and transmit the audio data in the original format to the Bluetooth host module; The data is encoded into a format supported by Bluetooth, that is, audio data in Bluetooth format, such as encoding audio data in Pulse Code Modulation (PCM) format into audio data in sub band coding (SBC) format; then Bluetooth The host module transmits the audio data in the bluetooth format to the bluetooth control module, and the bluetooth control module sends the audio data in the bluetooth format to the bluetooth headset or the bluetooth vehicle through the above bluetooth connection.

Among them, if the Bluetooth host module sends audio data in Bluetooth format to the Bluetooth control module, for example, under normal circumstances, the Bluetooth host module will send audio data in Bluetooth format to the Bluetooth control module every 20 milliseconds (ms). If the Bluetooth host module sends If the time interval of the data exceeds 50ms, the audio data heard in the Bluetooth headset or Bluetooth car will appear stuck or noise or intermittent problems. In this embodiment, the terminal device will automatically adjust the transmission power of the Bluetooth module when it detects that the time interval for the Bluetooth host module to send audio data in Bluetooth format to the Bluetooth control module is greater than a preset time value, such as 50ms, that is step 103 .

Step 103, the terminal device adjusts the transmission power of the Bluetooth control module in the Bluetooth module from the current first-level transmission power to the second-level transmission power, where the second-level transmission power is greater than the first-level transmission power.

Step 104, the Bluetooth module of the terminal device sends the played audio data to the Bluetooth headset or the Bluetooth car according to the second level of transmission power.

It can be seen that in this embodiment, the terminal device will determine that the Bluetooth host module sends the Bluetooth format audio to the Bluetooth control module during the process of sending the played audio data to the Bluetooth headset or the Bluetooth vehicle through the Bluetooth connection of the Bluetooth module of the terminal device. Whether the time interval of the data is greater than the preset first time value, if it is greater, adjust a certain function parameter, that is, adjust the transmission power of the Bluetooth module to eliminate the audio data that is listened to from the Bluetooth headset or Bluetooth car. Stuck, or A factor of murmur or staccato.

Further, referring to FIG. 3 , in a specific embodiment, after performing the above steps 101 to 104, the terminal device may also perform the following steps to adaptively adjust the transmit power of the Bluetooth module of the terminal device, specifically:

Step 201, the terminal device continues to judge whether the time interval for the Bluetooth host module to send audio data in Bluetooth format to the Bluetooth control module is greater than the preset time value, if it is still greater than that, it means that the transmission power adjusted by the terminal device through the above step 103 is not enough and needs to be executed Steps 202 and 203; if not greater, it means that the transmission power adjusted by the terminal device through the above step 103 is sufficient, and step 205 needs to be executed.

Step 202, judging whether the second level of transmission power is the highest level of transmission power of the Bluetooth module of the terminal device, if it is the highest level of transmission power, then it is impossible to eliminate the occurrence of audio stuttering or lagging in the Bluetooth headset or Bluetooth car by increasing the transmission power of the Bluetooth module.

Step 203, adjusting other functional parameters of the terminal device, such as disabling the wireless network function of the terminal device.

Step 204, continue to adjust the second level of transmission power according to the time interval of the bluetooth host module sending audio data in bluetooth format to the bluetooth control module, the specific adjustment method is similar to the method for adjusting the first level of transmission power in the above steps 102 and 103, different Yes, when adjusting the second level of transmission power, it is adjusted to a higher level of transmission power, and since the terminal device has adjusted the transmission power of the Bluetooth module to a relatively high value, when it is judged that the Bluetooth host module sends the Bluetooth format to the Bluetooth control module When the time interval of the audio data is not greater than the preset time value, the following step 205 may be performed.

Step 205, after the terminal device finishes playing the audio data, adjust the transmission power of the Bluetooth module to the lowest level of transmission power, so as to reduce the power consumption of the terminal device.

It can be seen that, in the above method, the terminal device can eliminate the problem of audio jamming, noise or interruption in the Bluetooth headset or Bluetooth car by adjusting the transmission power of the Bluetooth module to send audio data and other functional parameters.

In a specific embodiment, the terminal device can set the first adjustment priority for the transmission power of the Bluetooth module to send audio data, and the second adjustment priority of other functional parameters of the terminal device, that is, when it is judged that the Bluetooth host module sends the Bluetooth control module When the time interval for sending the audio data in Bluetooth format is greater than the preset time value, whether to adjust other function parameters first, or adjust the transmission power first; if the first adjustment priority is set higher than the second adjustment priority, then in Bluetooth When the time interval for the host module to send audio data in Bluetooth format to the Bluetooth control module is greater than the preset time value, the transmission power of the audio data sent by the Bluetooth module will be adjusted first. When the transmission power can no longer be adjusted, if the Bluetooth headset or Bluetooth car will still If there is a problem of audio freeze or noise or intermittent, adjust other functional parameters of the terminal device; if the first adjustment priority is set lower than the second adjustment priority, then the Bluetooth host module will send Bluetooth format audio to the Bluetooth control module When the time interval of the data is greater than the preset time value, adjust other functional parameters of the terminal device first. When other functional parameters cannot be adjusted, if the Bluetooth headset or Bluetooth car still has audio freezes or noises or intermittent problems, Then adjust the transmission power of the Bluetooth module to send audio data.
