RADIO-FREQUENCY POWER ADJUSTMENT METHOD, BLE CHIP, BLE DEVICE AND ELECTRONIC TERMINAL

Provided are a radio-frequency power adjustment method, a BLE chip, a BLE device and an electronic terminal. The radio-frequency power adjustment method comprises: acquiring the signal quality of a BLE link with an opposite BLE device; comparing the signal quality with a set threshold value to acquire the difference between the signal quality and the set threshold value; and sending a radio-frequency power adjustment request to the opposite BLE device according to the difference, so as to instruct the opposite BLE device to adjust the transmission power of the opposite BLE device according to the radio-frequency power adjustment request. By means of the embodiments of the present invention, the validity of a BLE link can be ensured while the power level of a BLE device changes, thus avoiding the disconnection of the BLE link, thereby ensuring normal data transmission between BLE devices. L'invention concerne un procédé de réglage de puissance radiofréquence, une puce BLE, un dispositif BLE et un terminal élec
