The same reference numerals in the drawings denote the same or similar structures, and thus, a repetitive description thereof will be omitted.
As shown in fig. 1, an embodiment of the present invention discloses a bluetooth headset communication method, which includes the following steps:
s110, the mobile terminal is controlled to establish a first Bluetooth connection with the Bluetooth headset and a second Bluetooth connection with the headset box respectively. And transmitting first Bluetooth data between the mobile terminal and the Bluetooth headset based on the first Bluetooth connection. Specifically, the bluetooth headsets in the present application are all TWS (True Wireless Stereo) bluetooth headsets. The earphone box is used for containing earphones when the earphones are not used, and can have a function of charging the Bluetooth earphones.
And S120, detecting a first packet loss rate of the first Bluetooth data in a transmission process, and when the first packet loss rate is greater than a first preset threshold value, acquiring a first signal intensity of the first Bluetooth connection, a second signal intensity of the second Bluetooth connection, and a third signal intensity of a Bluetooth signal between the earphone box and the Bluetooth earphone. Specifically, the first packet loss rate is a ratio between a data volume difference and a data volume sent by the mobile terminal, where the data volume difference is a difference between the data volume sent by the mobile terminal and the data volume received by the bluetooth headset. The first Signal Strength, the second Signal Strength, and the third Signal Strength may be obtained based on an RSSI (Received Signal Strength) value recorded in a bluetooth protocol (BLE protocol stack) used. The first preset threshold may be 10%.
S130, when the second signal strength and the third signal strength are both greater than the first signal strength, disconnecting the first bluetooth connection, and establishing a third bluetooth connection between the bluetooth headset and the headset case; and transmitting second Bluetooth data between the mobile terminal and the Bluetooth headset based on the second Bluetooth connection and the third Bluetooth connection. That is, the step is performed under the condition that the second signal strength is greater than the first signal strength, and the third signal strength is greater than the first signal strength.
In this step, that is, when it is detected that the data signal directly transmitted between the mobile terminal and the bluetooth headset is poor, in order to increase the transmission range of the bluetooth signal, the bluetooth data transmission is performed between the mobile terminal and the bluetooth headset based on the headset box as a relay device.

In this embodiment, the bluetooth headset has a first storage module for storing a data cache file. The data cache file is used for caching data to be played. And the data amount cached by the data caching file is equal to a fourth preset threshold value. That is, the data buffer file is audio data whose data frame amount is a fourth preset threshold value from the next frame of the currently played data frame.

The audio stream data packet is an audio stream with a preset data volume after the audio stream currently played by the bluetooth headset. That is, the audio stream currently played by the bluetooth headset and the audio stream data packet may be combined to form a continuous data stream for an audio file. For example, if the currently played audio stream is the data frames of the audio file from the 3 rd to the 6 th seconds (including the 6 th second), the audio stream packet may include the data frames of the audio file from the 7 th to the 10 th seconds. Therefore, the audio data can be continuously played in the process of switching the Bluetooth connection. And
and S123, storing the audio stream data packet in a second storage module, and keeping updating the audio stream data packet. That is, the audio stream data packet needs to be updated in real time along with the progress of the currently played audio stream, for example, if the previous audio stream data packet corresponds to the data frames from the 7 th second to the 10 th second in the audio file, and the currently played audio stream has been played to the 10 th second, the audio stream data packet needs to be updated to the data frames from the 11 th second to the 14 th second in the stored audio file.
The step S130 includes:
and when the second signal strength and the third signal strength are both greater than the first signal strength, disconnecting the first Bluetooth connection.

And
establishing a third Bluetooth connection between the Bluetooth headset and the headset box; and transmitting second Bluetooth data between the mobile terminal and the Bluetooth headset based on the second Bluetooth connection and the third Bluetooth connection.
Therefore, the audio data packet of the next time period can be used as a test data packet for testing the signal intensity between two devices, the signal intensity is detected, the multiplexing of the audio data packet is realized, and the storage space is saved; and the prepositive cache of the audio data stream can be realized in the process of switching the Bluetooth connection, the problem of short pause generated in the audio data playing process before the third Bluetooth connection is established is solved, the continuous and stable playing is realized, and the user experience is favorably improved.
