Bluetooth Connection suddenly doesn't work on ICS (LogCat inside)

Question

At first, I was able to easily connect/disconnect and receive from my bluetooth remote device with my android phone running ICS (4.0.4).
Recently, somehow, my app doesn't work anymore.
There's no error, just no data is sent or received, because there's no socket created in connection.
My first guess is my hardware, but it's not.
I tried my basic bluetooth connection apps and they won't work neither.
Here is the logcat :

I saw several people encounter the same problem with a bluetooth connection on ICS.
Also I tried to fix it using this, but it doesn't work either.
It says: Could not create Insecure RFComm Connection.

Here is the snippet:

private BluetoothAdapter btAdapter = null;
      private BluetoothSocket btSocket = null;
      private StringBuilder sb = new StringBuilder();

      private ConnectedThread mConnectedThread;

      // SPP UUID service
      private static final UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB");

      // MAC-address of Bluetooth module (you must edit this line)
      private static String address = "20:13:06:24:05:60";

OnCreate

btAdapter = BluetoothAdapter.getDefaultAdapter();

The bluetooth connection

private BluetoothSocket createBluetoothSocket(BluetoothDevice device) throws IOException {
          if(Build.VERSION.SDK_INT >= 10){
              try {
                  final Method  m = device.getClass().getMethod("createInsecureRfcommSocketToServiceRecord", new Class[] { UUID.class });
                  return (BluetoothSocket) m.invoke(device, MY_UUID);
              } catch (Exception e) {
                  Log.e(TAG, "Could not create Insecure RFComm Connection",e);
              }
          }
          return  device.createRfcommSocketToServiceRecord(MY_UUID);
      }

      public void bluetoothDisconnect(){
          try     {
              btSocket.close();
            } catch (IOException e2) {
              errorExit("Fatal Error", "In onPause() and failed to close socket." + e2.getMessage() + ".");
            }

      }

      public void bluetoothConnect(){
        // Set up a pointer to the remote node using it's address.
            BluetoothDevice device = btAdapter.getRemoteDevice(address);

            // Two things are needed to make a connection:
            //   A MAC address, which we got above.
            //   A Service ID or UUID.  In this case we are using the
            //     UUID for SPP.

            try {
                btSocket = createBluetoothSocket(device);
            } catch (IOException e) {
                errorExit("Fatal Error", "In onResume() and socket create failed: " + e.getMessage() + ".");
            }

            /*try {
              btSocket = device.createRfcommSocketToServiceRecord(MY_UUID);
            } catch (IOException e) {
              errorExit("Fatal Error", "In onResume() and socket create failed: " + e.getMessage() + ".");
            }*/

            // Discovery is resource intensive.  Make sure it isn't going on
            // when you attempt to connect and pass your message.
            btAdapter.cancelDiscovery();

            // Establish the connection.  This will block until it connects.
            Log.d(TAG, "...Connecting...");
            try {
              btSocket.connect();
              Log.d(TAG, "....Connection ok...");
            } catch (IOException e) {
              try {
                btSocket.close();
              } catch (IOException e2) {
                errorExit("Fatal Error", "In onResume() and unable to close socket during connection failure" + e2.getMessage() + ".");
              }
            }

            // Create a data stream so we can talk to server.
            Log.d(TAG, "...Create Socket...");

            mConnectedThread = new ConnectedThread(btSocket);
            mConnectedThread.start();


      }

Is this issue fixable? Especially for this android version?
Thanks
