Abstract
(EN)
The present application provides a bluetooth positioning method and a bluetooth device. The bluetooth positioning method is applied to a first device, and the first device adopts a bluetooth low energy (BLE) mode to communicate with a second device. The bluetooth positioning method comprises: the first device sends first data to the second device in a first frame format including a bluetooth data frame and a first sub-frame, the first sub-frame being used for carrying angle of arrival (AoA) / angle of departure (AoD) information of the first device; when the signal quality satisfies a preset condition, the first device sends second data to the second device in a second frame format including the first sub-frame and the bluetooth data frame which has undergone encoding processing. The technical solution of the present application is able to improve the positioning efficiency.

La présente invention concerne un procédé de positionnement Bluetooth et un dispositif Bluetooth. Le procédé de positionnement Bluetooth est appliqué à un premier dispositif, et le premier dispositif adopte un mode Bluetooth à basse consommation (BLE) pour communiquer avec un second dispositif. Le procédé de positionnement Bluetooth comprend : l'envoi par le premier dispositif de premières données au second dispositif dans un premier format de trame comprenant une trame de données Bluetooth et une première sous-trame, la première sous-trame étant utilisée pour transporter des informations d'angle d'arrivée (AoA)/angle de départ (AoD) du premier dispositif ; lorsque la qualité de signal satisfait une condition prédéfinie, l'envoi par le premier dispositif de secondes données au second dispositif dans un second format de trame comprenant la première sous-trame et la trame de données Bluetooth ayant subi un traitement de codage. La solution technique de la présente invention est apte à améliorer l'efficacité de positionnement.
