setRangingListener works but setNearableListener doesn't

Greetings, a bit similar to this thread (OnNearablesDiscovered returns empty list?), in an Amazon Fire, with Android 4.4, setRangingListener does return a list with beacons, but setNearableListener always returns an empty list. If they didn’t show in either, I could think their battery is dead.

I’m basically using the demo code in the SDK for BeaconManager.

private static final UUID ESTIMOTE_PROXIMITY_UUID = UUID.fromString("B9407F30-F5F8-466E-AFF9-25556B57FE6D");
private static final Region ALL_ESTIMOTE_BEACONS = new Region("rid", ESTIMOTE_PROXIMITY_UUID, null, null);

beaconManager.setRangingListener(new BeaconManager.RangingListener() {
    public void onBeaconsDiscovered(Region region, List<Beacon> beacons) {
        for (Beacon beacon : beacons)
            Log.d(TAG, "Beacon: " + String.format("%d:%d", beacon.getMajor(), beacon.getMinor()));

beaconManager.setNearableListener(new BeaconManager.NearableListener() {
    public void onNearablesDiscovered(List<Nearable> nearables) {
        Log.d(TAG, "Discovered nearables: " + nearables);

beaconManager.connect(new BeaconManager.ServiceReadyCallback() {
    @Override public void onServiceReady() {

        // Beacons ranging.
        Log.d(TAG, "Starting ranging discovery");

        // Nearable discovery.
        Log.d(TAG, "Starting nearable discovery");

Logcat shows

08-21 16:33:11.080 20383-20383/ D/MainActivity: Discovered nearables: []
08-21 16:33:11.080 20383-20383/ D/MainActivity: Beacon: 49162:44197
08-21 16:33:11.080 20383-20383/ D/MainActivity: Beacon: 23804:13389
08-21 16:33:11.080 20383-20383/ D/MainActivity: Beacon: 34225:35093

Over and over, nearables is always empty.

I tried add an ErrorListener to see if there was an error,

beaconManager.setErrorListener(new BeaconManager.ErrorListener() {
    public void onError(Integer integer) {
        Log.d(TAG, "Error id: " + integer);

But it never gets called

In my build.gradle I have this line

compile ‘com.estimote:sdk:0.11.0@aar’

setRangingListener is for Estimote Beacons, setNearableListener is for Estimote Stickers set to broadcast the Nearable packet (it is by default). Do you have beacons or stickers?

can you share doc file or link , where define every method with types of beacons
