Comment faire pour se connecter avec un appareil compatible Bluetooth couplé programmatique dans Android?

Je développe une application où j'ai pour vous connecter à des périphériques Bluetooth de l'appareil lié. Ces deux appareils sont connectés les uns avec les autres. Maintenant, quand j'essaie de me connecter avec un appareil couplé ça collait avec le mode de connexion de boîte de dialogue. Journal montre qu'il a réussi à se connecter, mais ne pas fermer la boîte de dialogue.

Voici mon extrait de code.

Où vais mal? Quelqu'un qui a réussi à configurer le Bluetooth avec le dialogue de traitement, Merci de me donner un coup de main.
