My app can't find beacons

[omicito]

Prerequisites

• Put an X between the brackets on this line if you have done all of the following:
  • My beacons have Estimote Location packet enabled (Check it in the Estimote Cloud, or via app)
  • My Android device/devices supports BLE and has Android OS version >= 5.0.0
  • My Android device/devices have bluetooth enabled
  • My app has Location Permissions granted

Basic information

Estimote SDK version: 2.5.3

Android devices affected: Xiaomi Redmi Note 4

Beacon hardware version: D3.4

Description

I am building an Android app for an indoor location using Android Indoor SDK.
The issue is that my phone can't find any beacons near and it is not showing my location.
The Estimode app finds beacons, but my app is not scanning them.
When I debugged, I saw that the "location" object has scannedBeacon member and its value is 0.
The location is mapped and successfully shown on my app, along with the beacon's position.
The Bluetooth is on and scanning, I can see this in the log:
D/BluetoothAdapter: STATE_ON
D/BluetoothLeScanner: onClientRegistered() - status=0 clientIf=10 mClientIf=0

In the setOnPositionUpdateListener, it always goes on onPositionOutsideLocation(), he can't find any beacons and he thinks he is outside of the room.

Please, can you help me?
