Beacon Not Detected by AltBeacon Library

[shazleenn]

I am experiencing an issue where my Estimote beacon is not being detected by the AltBeacon library in my Android application. The beacon is visible in third-party apps like Mobile Beaconer and BeaconScope but not in my app.

Steps to Reproduce:
Configure the Estimote beacon with the following settings:
Namespace ID: edd1ebeac04e5defa017
Instance ID: f1e83900106d
Advertising Interval: 300 ms
Transmit Power: Weak (-12 dBm)

Add the AltBeacon library to the Android project:
gradle

implementation 'org.altbeacon:android-beacon-library:2.19.5'

the relevant code :

private void startBeaconDetection() {
beaconManager = BeaconManager.getInstanceForApplication(this);

beaconManager.getBeaconParsers().clear();
beaconManager.getBeaconParsers().add(new BeaconParser().setBeaconLayout("s:0-1=feaa,m:2-2=00,p:3-3:-41,i:4-13,i:14-19"));

beaconManager.setForegroundScanPeriod(5000L); // Scan for 5 seconds
beaconManager.setForegroundBetweenScanPeriod(0L); // No interval between scans
beaconManager.setBackgroundScanPeriod(5000L); // Scan for 5 seconds
beaconManager.setBackgroundBetweenScanPeriod(0L); // No interval between scans
beaconManager.setRegionStatePersistenceEnabled(false);

beaconManager.bind(this);

}

@OverRide
public void onBeaconServiceConnect() {
beaconManager.addRangeNotifier(new RangeNotifier() {
@OverRide
public void didRangeBeaconsInRegion(Collection beacons, Region region) {
if (beacons.size() > 0) {
for (Beacon beacon : beacons) {
String namespace = beacon.getId1().toString();
String instance = beacon.getId2().toString();
String beaconInfo = "Beacon detected: Namespace = " + namespace + ", Instance = " + instance + ", RSSI = " + beacon.getRssi();
Log.d(TAG, beaconInfo);
runOnUiThread(() -> beaconTextView.setText(beaconInfo));
}
} else {
runOnUiThread(() -> beaconTextView.setText("Searching..."));
}
}
});

try {
    Identifier namespaceId = Identifier.parse("edd1ebeac04e5defa017");
    Identifier instanceId = Identifier.parse("f1e83900106d");
    Region region = new Region("myRangingUniqueId", namespaceId, instanceId, null);
    beaconManager.startRangingBeacons(region);
} catch (Exception e) {
    Log.e(TAG, "Cannot start ranging", e);
}

}
