I can't get list of all uwb estimote beacons when we enter in beacon range android

Question

Here is my code

I have 3 beacons on cloud estimote account. All 3 beacons put on some distance with same floor but i can't get all beacon details when I enter in beacon range area. please help me what is wrong with my code.

private void beaconRegionConfig() {

    BeaconRegion beaconRegion = new BeaconRegion("", null, null, null);
    beaconManager.setBackgroundScanPeriod(5000, 30000);
    beaconManager.setForegroundScanPeriod(10000, 5000);

    beaconManager.connect(() -> {
        beaconManager.startRanging(beaconRegion);
        beaconManager.setConfigurableDevicesListener(configurableDevices -> {
            Log.e(TAG, "configurableDevicesList =  " + configurableDevices);
        
        });
    
    });


    // Set up ranging for get all beacons
    beaconManager.setRangingListener(new BeaconManager.BeaconRangingListener() {
        @Override
        public void onBeaconsDiscovered(BeaconRegion region, List<Beacon> beacons) {
            // Handle discovered beacons here
            //Log.e(TAG, "region: " + region);
            Log.e(TAG, "region " + region + " , _beaconsSize: " + beacons.size() + " ," + beacons);
        }
    });
 
}

I Get o/p like this

proximityUUID=5861636c-716e-2301-be01-6c731222f008, major=1,
