Specifically, the electronic device can reduce the bluetooth transmission power of the electronic device when the RSSI is greater than the second preset threshold value, obtain the second target bluetooth transmission power, and control the electronic device to work with the second target bluetooth transmission power, so that not only the communication quality is ensured to a certain extent, but also the power consumption of the electronic device can be reduced.

For example, in a specific implementation, the bandwidth in the bluetooth 5 protocol may be automatically adjusted according to the communication distance and the signal strength, for example, a 125kbps mode is selected for a long distance, and a 2Mbps mode is selected for a short distance, so that communication within a certain distance range is guaranteed without being blocked, and for example, the headset mode of bluetooth may be adjusted according to the communication distance and the signal strength, for example, a bluetooth high-quality headset function may be turned on for a short distance, and only the most basic voice communication is guaranteed for a long distance without guaranteeing the quality of sound.

Based on the method described in the present application, in the embodiment of the present application, in order to intelligently control the power consumption of the bluetooth module, the working power of the bluetooth module may be maintained at the minimum level when the communication link is stable as much as possible. The power control is adjusted based on its RSSI (received signal strength indicator) value.
