I think linux use bluetooth need specify the connect port.

      try {
            Method m = remoteDevice.getClass().getMethod("createRfcommSocket", new Class[] {int.class});
            try {
                BluetoothSocket tmp = (BluetoothSocket)m.invoke(remoteDevice, 1);
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                e.printStackTrace();
            }
        } catch (NoSuchMethodException e) {
            e.printStackTrace();
        }
