Abstract

Selon la présente invention, la fonction Bluetooth peut être utilisée même si une application existante inadaptée aux spécifications techniques de Bluetooth est utilisée et même si l'environnement du système est également inadapté aux spécifications de Bluetooth, même par une modification pouvant être effectuée au niveau de l'utilisateur, telle qu'une modification des paramètres ou une modification partielle d'un ou plusieurs programmes ou d'une bibliothèque, et plus précisément une correction de logiciel. Une unité (10) Bluetooth exécute une communication de données sans fil courte distance conformément aux spécifications techniques de Bluetooth au moyen d'une unité de commande (14) HCI actionnée par une commande HCI et un module (12) Bluetooth commandé par l'unité de commande (14) HCI. Entre une interface (16) de connexion de l'unité (10) Bluetooth avec un hôte (20) et l'unité de commande (14) HCI, un émulateur (30) de commande est interposé pour exécuter une transformation de commande par un procédé d'interprétation entre l'hôte (20) et l'unité de commande (14) HCI.
