Android Bluetooth Send Message Working First Time Only

I need to send string message from Raspberry PI to Android device. I am getting message first time only. After that it does not work at all. I am using PYTHON code in Raspberry PI.

Solution 1:

We just need to add some code into manageConnectedSocket block. Basically we need to cancel the acceptThread if not null and restart the service:

private void manageConnectedSocket(BluetoothSocket socket) {
    Log.i(TAG, "Hurray!! I am here");
    //
    if (acceptThread != null) {
        acceptThread.cancel();
        acceptThread = null;
    }
    //
    if (acceptThread == null) {
        acceptThread = new AcceptThread();
        acceptThread.start();
    }
}
