Send Command to Bluetooth from Android device

Question

I am getting a issue to send Commands from my android device to Bluetooth device.

Bluetooth is associated with a micro-controller. My effort is below:

Answer 1

As you have mentioned that the issue is there on mmSocket.connect(); line hence, the problem is not while you are sending the command but creating a connection i.e. you are not able to retrieve a BluetoothSocket in opened or connected state.

What should you do ?

Try to use the below code with UUID , its valid for my bluetooth dongles.

UUID MY_UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB"); createInsecureRfcommSocketToServiceRecord(MY_UUID)

Let me know if this works for you.
