			TextView topStatusTextView = FindViewById<TextView> (Resource.Id.TopStatusTextView);
			if (!bluetoothAdapter.IsEnabled) {
				Intent enableBluetooth = new Intent (BluetoothAdapter.ActionRequestEnable);
				StartActivityForResult (enableBluetooth, 1);
			}													
			Java.Util.UUID serialUUID = Java.Util.UUID.FromString ("00001101-0000-1000-8000-00805F9B34FB");
			BluetoothDevice bluetoothDevice = bluetoothAdapter.GetRemoteDevice ("00:26:5E:DE:7D:FC");
			BluetoothSocket bluetoothSocket = null;
			Stream outStream = null;
			bluetoothSocket = bluetoothDevice.CreateRfcommSocketToServiceRecord (serialUUID);	
			bluetoothSocket.Connect();
