Solution 1:

Edit:

You need to connect to the socket, before that you need to cancel the discovery

 btAdapter.cancelDiscovery();
 socket.connect();

UUID worked for Kiran K J is

You Haven't get the Bluetooth Adapter, you have just declared it.

Get the bluetooth adapter like this using static factory method

Add this in onCreate

btAdapter=BluetoothAdapter.getDefaultAdapter();
