Further, after the bluetooth detection function of the mobile phone end is started in S1, acquiring state information of the mobile phone end system, and if the mobile phone end system is not in a busy state, waking up and running a bluetooth search thread; the non-busy state refers to a state that the mobile phone end system is in a standby state or an operation interval is less than or equal to 5 seconds.
In order to further reduce the power consumption of the mobile phone end and improve the user experience, the technical scheme acquires the state information of the mobile phone end system after the Bluetooth detection function of the mobile phone end is started, acquires the operation behavior of the user at the mobile phone end to determine the state of the mobile phone end system, avoids the interruption of the in-use function of the user caused by the Bluetooth detection in the user operation, and also avoids the phenomenon that the in-use function of the user is wrong or unsmooth because a Bluetooth searching thread occupies a system memory, so that the user experience is poor. By using the method of the technical scheme, the detection process can be ensured to run in the background after the Bluetooth detection function of the mobile phone terminal is started, and a user does not need to stay in a Bluetooth operation interface of the mobile phone terminal for a long time, so that the user experience is improved. It should be noted that, in the technical scheme, if the mobile phone end system is in a busy state, the mobile phone end system waits until the mobile phone end system is in a non-busy state, and wakes up and runs a bluetooth search thread; if the Bluetooth searching thread is started and enters a background, the Bluetooth searching thread is suspended until the mobile phone end system is in the non-busy state after the mobile phone end enters the non-busy state during the operation of the user. In addition, according to the technical scheme, the backlight time setting of the screen can be read, and the thread suspends work after the screen of the mobile phone end is turned off.
Further, the bluetooth search thread is an independent thread, and the bluetooth search thread proceeds to step S2 each time it runs to search for a bluetooth device signal.

In order to increase the accuracy of the obtained distance of the Bluetooth equipment, the optimized distance of the Bluetooth equipment is obtained by performing deviation optimization calculation on the quantized original distance of the Bluetooth equipment, when the number of the original distance of the Bluetooth equipment is smaller than a preset value, the obtained original distance of the Bluetooth equipment is mostly concentrated in a certain numerical range, so that the distance of the Bluetooth equipment can be visually represented by calculating the average value of the distances of the original Bluetooth equipment which does not exceed the preset deviation value, and when the number of the original distance of the Bluetooth equipment is larger than the preset value, the optimized distance of the Bluetooth equipment can be more represented by calculating the weight factor; by adopting the method, the distance of the Bluetooth equipment meeting the detection requirement can be obtained, the energy consumption in the calculation process can be reduced, the detection efficiency is improved, and the user experience is further improved. (ii) a Preferably, the third weighting factor is 0.6 and the fourth weighting factor is 0.4.

When the mobile phone end is connected with the wireless earphone through Bluetooth, the Bluetooth signal strength can confirm the speed of Bluetooth transmission after connection, the distance of the Bluetooth equipment can determine whether the current wireless earphone is the earphone used by the user, and the earphone can be used as the basis for judging whether the user selects the current wireless earphone.
Further, the first weight factor + the second weight factor is 1, the first weight factor is greater than the second weight factor, and the verification value is × the first weight factor + the bluetooth device distance × the second weight factor.
This technical scheme is for preventing that the cell-phone end user mistake places bluetooth headset in the position far away in the in-service use, and the weighted value of setting for bluetooth signal intensity is greater than the bluetooth equipment distance, makes the verification process of the second time more reasonable. Preferably, the first weighting factor is 0.8 and the second weighting factor is 0.2.
