Envoi d’images via Bluetooth du PC vers le mobile

API Bluetooth – est une bonne idée
Vous pouvez utiliser les étapes suivantes :
1. Énumérer les services téléphoniques disponibles avec les fonctions WSALookupServiceBegin, WSALookupServiceNext
2. Obtenez l’adresse du service OBEX File Transfer
3. Créer une prise Bluetooth
4. Connectez-vous à l’adresse de service trouvée
5. Implémentez le protocole OBEX File Transfer (commandes Connect et Put – http://netwinder.osuosl.org/pub/netwinder/docs/nw/irda/IrOBEX12.pdf[^], http://dotcom.bluetoothsig.org/SiteCollectionDocuments/GOEP_SPEC_V12.pdf[^]) et envoyez le fichier via le socket
Je peux partager mon propre projet de test, mais je ne sais pas comment le joindre à la solution
