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

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

_beaconsSize: 1 ,[Beacon{macAddress=[F0:1A:A0:11:D5:A8], 
proximityUUID=5861636c-716e-2301-be01-6c731222f008, major=1, 
  minor=0, measuredPower=-53, rssi=-102}]

In menifest file

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
<uses-permission android:name="android.permission.INTERNET" />

<!-- for beacons-->
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_BACKGROUND_LOCATION"/>

<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.BLUETOOTH_SCAN"/>

In gradle

  implementation 'com.estimote:sdk:1.0.12'

This 3 beacons in my estomote cloud account

Estimote Team here,

it seems you have Estimote UWB Beacons, but the code you posted is related to BLE beacons.

Estimote had two generation of beacons:

  1. BLE (Bluetooth) popular in 2013-2019. They were typically configured as iBeacon or Eddystone and allowed phones to detect them with 1-3m accuracy. They were typically green, blue or white.

  2. UWB (Ultra Wideband) launched in 2019 that are configured with FiRa protocol and compatible with U1/U2 UWB chip from Apple and Core UWB JetPack library from Google Android. They provide 10cm accuracy. They were typically yellow, caramel, white like this:

Estimote UWB Beacons

Mobile SDK for these UWB beacons are here:

Please note UWB Beacons have also BLE radio, but it is mostly used to discover these beacons before connecting to them via UWB.

Typical cycle is:

  1. Phone does start scanning over BLE
  2. Phone discovers UWB beacons via BLE
  3. Phone connects to UWB beacon via BLE
  4. Phone starts ranging with UWB beacons via UWB
  5. Phone obtains distance to UWB beacon
  6. Phone disconnects from UWB beacon

So the proper way to discover these UWB beacons on Android would be:

uwbManager.startDeviceScanning(this)

Then you can print discovered UWB beacons like this:

uwbManager.uwbDevices.collect { scanResult: EstimoteUWBScanResult ->
    when (scanResult) {
        is EstimoteUWBScanResult.Devices -> {
            scanResult.devices.forEach { device ->
                println("Discovered device: ${device.deviceId} rssi: ${device.rssi}")
            }
        }
        else -> println("No devices found or error occurred")
    }
}

you should see something like this:

Discovered device: 317804 rssi: -71 Discovered device: b288ef rssi: -40

And then after you connect to each beacon and range via UWB you should see:

Device address prefix: 02:39:.... Distance 0.99 m, Azimuth: -40.240578, Elevation angle: 18.97932
Device address prefix: 02:39:.... Distance 0.86 m, Azimuth: -33.938553, Elevation angle: 57.48887
