Je veux utiliser Android 2.1 pour me connecter à un périphérique Bluetooth externe, qui offre un port SPP pour moi. Dans ce cas, il s'agit d'une unité GPS externe. Lorsque j'essaie de me connecter, je ne peux pas connecter une socket établie en mode "client". Ensuite, si je tente de configurer un socket (étant dans le rôle de serveur), pour recevoir du texte à partir de mon PC, tout fonctionne très bien. L'ordinateur peut se connecter en tant que client au socket sur le téléphone via SPP à l'aide de l'UUID SSP ou d'un UUID aléatoire. Donc, le problème n'est pas que j'utilise le mauvais UUID.SPP Socket createRfcommSocketToServiceRecord ne se connecte pas
Mais l'inverse (par exemple l'appel de la connexion sur la socket client établie) createRfcommSocketToServiceRecord(UUID uuid)) ne fonctionne tout simplement pas. Malheureusement, j'ai n'a pas le temps d'inspecter le problème plus loin. Ce serait grand si quelqu'un pouvait me pointer du bon côté. Téléphone: Samsung Galaxy Spica I-5700 Android 2.1 Dans la partie suivante du fichier journal doit être le problème.
