Abstract

La présente invention est applicable au domaine technique de la transmission sans fil en champ proche, et concerne un procédé de communication complémentaire à deux supports ainsi qu'un appareil et un système de communication sans fil. Le procédé comprend les étapes qui consistent : à lancer un module de communication sans fil pour qu'il se connecte à un premier appareil de communication sans fil et qu'il communique avec lui ; et, lorsque des informations de connexion sans fil concernant le premier appareil de communication sans fil ne peuvent pas être reçues, à recevoir, au moyen d'un module de microphone, des informations d'ondes sonores envoyées par le premier appareil de communication sans fil correspondant à un numéro de dispositif à ondes sonores attribué, de façon à réaliser une communication sur ondes sonores, les informations d'ondes sonores étant N séquences d'ondes sonores haute fréquence générées selon le numéro de dispositif à ondes sonores et transmises sur une première durée prédéfinie servant de période d'intervalle, et N étant un nombre entier positif supérieur ou égal à 1. Dans la présente invention, une communication radio auxiliaire est réalisée au moyen de la réception et de l'envoi d'ondes sonores, de sorte que la connexion est plus robuste, le fonctionnement d'un système sans fil nettement plus fiable, et l'expérience d'utilisation considérablement améliorée.
