For example, in the specific implementation, the bandwidth in the Bluetooth 5 protocol can be automatically adjusted according to the communication distance and signal strength. For example, the 125kbps mode is selected for a long distance, and the 2Mbps mode is selected for a short distance, which can ensure that the communication will not be stuck within a certain distance. For another example, the Bluetooth headset mode can be adjusted according to the communication distance and signal strength. For example, the Bluetooth high-quality headset function can be turned on at a short distance, and only the most basic voice communication is guaranteed at a long distance, but the sound quality is not guaranteed.
