Description

I've been trying to use the new SDK (Proximity) and this one, none of them seems to work on my case. onBeaconsDiscovered is always returning me a empty list with beacons. Once I open the Estimote App and hit Devices, the list returns 7 beacons. Once I close the app a few moments later the list starts to decrease, until it reaches 0 again. Code is attached bellow.

Logs and code

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        SystemRequirementsChecker.checkWithDefaultDialogs(this);

        manager = new BeaconManager(getApplicationContext());
        manager.connect(new BeaconManager.ServiceReadyCallback() {
            @Override
            public void onServiceReady() {
                BeaconRegion region = new BeaconRegion("MyRegion", UUID.fromString("B9407F30-F5F8-466E-AFF9-25556B57FE6D"), null,null);
                manager.startRanging(region);
                manager.setRangingListener(new BeaconManager.BeaconRangingListener() {
                    @Override
                    public void onBeaconsDiscovered(BeaconRegion beaconRegion, List<Beacon> beacons) {
                        System.out.println(beacons.size() + " <<< Beacons Size");
                    }
                });
            }
        });

    }

I am facing the same issue in Nokia (Android version 9). Estimote SDK Version : 1.4.5 After few hours of scan i get empty beacons. And again when i open my app it will give me nearby list of beacons.

What is the cause and what is the solution?
