mmSocket= device.createRfcommSocketToServiceRecord(uuidToTry);
try
{
    mmSocket.connect();
}
catch (IOException e)
{
    mmSocket.close();
}

You can do it like this- Create a broadcast receiver in your code Like this:

private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals(BluetoothAdapter.ACTION_STATE_CHANGED)) {
            BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
            if (!mBluetoothAdapter.isEnabled()) {
                // BT is turened off.
            }
            else{
                // BT is turened on.
              }
        }
 }
};

and register that broadcastreceiver for following intent filter:

IntentFilter filter = new IntentFilter(BluetoothAdapter.ACTION_STATE_CHANGED); registerReceiver(mReceiver, filter);
