Abstract
(EN)
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 électronique. Le procédé de réglage de puissance radiofréquence comprend : l'acquisition de la qualité de signal d'une liaison BLE avec un dispositif BLE opposé ; la comparaison de la qualité de signal avec une valeur de seuil définie pour acquérir la différence entre la qualité de signal et la valeur de seuil définie ; et l'envoi d'une requête de réglage de puissance radiofréquence au dispositif BLE opposé en fonction de la différence, de sorte à ordonner au dispositif BLE opposé de régler la puissance de transmission du dispositif BLE opposé en fonction de la requête de réglage de puissance radiofréquence. Au moyen des modes de réalisation de la présente invention, la validité d'une liaison BLE peut être assurée tandis que le niveau de puissance d'un dispositif BLE change, évitant ainsi la déconnexion de la liaison BLE, assurant ainsi une transmission normale de données entre des dispositifs BLE.
