Envoyer des sms via une connexion Bluetooth à partir d'un Serveur Java pour Android Client

Tout d'abord... de ne pas me diriger vers Bluetooth Chat et j'ai entièrement lu.

J'ai un Client Android qui stablishes correctement la connexion avec le serveur, et ce qui est plus que je peux envoyer des sms vers le serveur sur mon pc et de l'afficher correctement, mais je ne peux pas faire le contraire de l'action, d'envoyer une simple chaîne de caractères à partir du serveur vers le client et de le montrer dans mon application android.

Je ne veux pas mettre en œuvre un chat c'est juste pour montrer comment BT communication fonctionne entre un Serveur Java et Android Client.

Pour le rendre facile:

J'envoie le texte à la fin de la startServer() dans la classe de serveur.

J'essaie de lire le texte à partir du serveur au début de onPause().

Le code est comme suit:

Android BT Client:

/*...libraries here...*/
public class ConnectTest extends Activity {
TextView out;
private static final int REQUEST_ENABLE_BT = 1;
private BluetoothAdapter btAdapter = null;
private BluetoothSocket btSocket = null;

et la Java BT Serveur:

/**

*/
public class SimpleSPPServer {
//start server
private void startServer() throws IOException{
//Create a UUID for SPP
UUID uuid = new UUID("1101", true);
//Create the servicve url
String connectionString = "btspp://localhost:" + uuid +";name=Sample SPP Server";
//open server url
StreamConnectionNotifier streamConnNotifier = (StreamConnectionNotifier)Connector.open( connectionString );
//Wait for client connection
System.out.println("\nServer Started. Waiting for clients to connect...");
StreamConnection connection=streamConnNotifier.acceptAndOpen();
RemoteDevice dev = RemoteDevice.getRemoteDevice(connection);
System.out.println("Remote device address: "+dev.getBluetoothAddress());
System.out.println("Remote device name: "+dev.getFriendlyName(true));
//read string from spp client

bWriter.write("Response String from SPP Server\r\n");
/*PrintWriter pWriter=new PrintWriter(new OutputStreamWriter(outStream));

streamConnNotifier.close();
}
public static void main(String[] args) throws IOException {
//display local device address and name
LocalDevice localDevice = LocalDevice.getLocalDevice();
System.out.println("Address: "+localDevice.getBluetoothAddress());

sampleSPPServer.startServer();
}
}

Solution:
C'est juste un petit changement dans le côté serveur.
Je ne sais pas pourquoi, mais au lieu d'utiliser BufferedWrite à écrire dans le support, nous avons besoin d'utiliser PrinterWriter de le faire. - Je ajouter ce bout de code modifié:

BT Serveur:

    ....
//read string from spp client
InputStream inStream=connection.openInputStream();
BufferedReader bReader=new BufferedReader(new InputStreamReader(inStream));
String lineRead=bReader.readLine();
System.out.println(lineRead);
//send response to spp client
OutputStream outStream=connection.openOutputStream();
PrintWriter pWriter=new PrintWriter(new OutputStreamWriter(outStream));
pWriter.write("Response String from SPP Server\r\n");
pWriter.flush();
pWriter.close();
streamConnNotifier.close();
...
