обнаружить iBeacon с помощью библиотеки altbeacon

Надеюсь, что это поможет вам

public class RangingActivity extends Activity implements BeaconConsumer {
    protected static final String TAG = "RangingActivity";

    private static final String UUID = "XXXXXXXXXXXXXXXXXXXX";
    private BeaconManager beaconManager = BeaconManager.getInstanceForApplication(this);

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_ranging);
        beaconManager.bind(this);
    }
    @Override 
    protected void onDestroy() {
        super.onDestroy();
        beaconManager.unbind(this);
    }
    @Override
    public void onBeaconServiceConnect() {
        beaconManager.setRangeNotifier(new RangeNotifier() {
        @Override 
        public void didRangeBeaconsInRegion(Collection<Beacon> beacons, Region region) {
            if (beacons.size() > 0) {
                Log.i(TAG, "The first beacon I see is about "+beacons.iterator().next().getDistance()+" meters away.");     
            }
        }
        });

        try {
            beaconManager.startRangingBeaconsInRegion(new Region("myRangingUniqueId", Identifier.parse(UUID), null, null));
        } catch (RemoteException e) {   }

        beaconManager.getBeaconParsers().add(new BeaconParser()
           .setBeaconLayout("m:2-3=0215,i:4-19,i:20-21,i:22-23,p:24-24"));

    }
}

передать мажор и минор вместо нуля

  Region region = new Region("myRangingUniqueId", uUID, major, minor);
