Indoor location app stuck trying to find beacons

Hi,
When I try to create indoor location app gets stuck with message "Looking for beacons…"
These are new beacons, updated firmware to 4.13.2, and hardware to F3.3.
Estimote Location are enable on all 6 beacons, with +4 dBs and interval 200 ms.
Yet nothing seems to be working, what am I doing wrong? Help will be appreciated.

Cheers

Cześć!
