Abstract

L'invention concerne un procédé de fonctionnement d'un casque sans fil qui permet d'intégrer le casque sans fil à un dispositif de communication électronique. Le procédé de l'invention consiste à détecter une connexion câblée entre le casque sans fil et un dispositif de communication électronique, à savoir lorsque le casque sans fil est installé dans une interface du dispositif de communication électronique. Un protocole de connexion sans fil est ensuite désactivé en réponse à la détection de la connexion câblée (bloc 510). Une déconnexion de la connexion câblée est ensuite détectée, à savoir lorsque le casque sans fil est retiré de l'interface dans le dispositif de communication électronique (bloc 515). Le protocole de connexion sans fil est ensuite activé en réponse à la détection de la déconnexion de la connexion câblée, et une connexion sans fil est ainsi établie entre le casque sans fil et le dispositif de communication électronique (bloc 520).
