This code fragment works as expected:

LocalBluetoothDevice local = LocalBluetoothDevice.initLocalDevice(this);

if (local.isEnabled()) {
   if (! local.isScanning()) {
      local.scan();
   }
}

Be sure, if you enable Bluetooth with
LocalBluetoothDevice.getLocalDevice().setEnabled(true) to wait for the event 
that
notifies that Bluetooth service has been activated. Otherwise it won't work.
