Estoy tratando de crear un programa simple que busque un auricular bluetooth (estoy probando con un auricular PS3) y luego me conecto a él. Estoy usando el código del bluetooth chat program example. Sin embargo, no puedo conectarlo a nada. Me está dando una Excepción de E/S cuando llega a connect().Conectar/Par Auriculares Bluetooth y Android
private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");
Este hilo se ejecuta al intentar realizar una conexión saliente con un dispositivo. Corre recto; la conexión tiene éxito o falla.
private class ConnectThread extends Thread {

BluetoothSocket tmp = null;
// Get a BluetoothSocket for a connection with the given BluetoothDevice
try {
tmp = device.createRfcommSocketToServiceRecord(MY_UUID);
} catch (IOException e) {
Log.e(TAG, "create() failed", e);
}
if (tmp == null){
Log.i(TAG, "tmp is NULL");
}
mmSocket = tmp;
}
public void run() {
Log.i(TAG, "BEGIN mConnectThread");
setName("ConnectThread");
// Always cancel discovery because it will slow down a connection
mAdapter.cancelDiscovery();
Log.i(TAG, "discovery is cancelled");
// Make a connection to the BluetoothSocket
try {
// This is a blocking call and will only return on a successful connection or an exception
mmSocket.connect(); //Doesn't like something here???
} catch (IOException e) {
Log.e(TAG, "IO error, ", e);
connectionFailed();
// Close the socket
try {
mmSocket.close();
} catch (IOException e2) {
Log.e(TAG, "unable to close() socket during connection failure", e2);
}
// Start the service over to restart listening mode

return;

synchronized (newBluetoothService.this) {

}
// Start the connected thread
connected(mmSocket, mmDevice);

Cualquier ayuda es muy apreciada.

Estoy probando en un Droid X con la actualización 2.2 y un auricular Bluetooth PS3. Está siendo emparejado, pero no se conectará. Puedo conectar manualmente el auricular cuando entro en la configuración de bluetooth. –
