Proximity zone distances


I am using Proximity SDK on UWB Beacons.
I made an Android demo app to register “enter”/“exit” events.

The problem is that the “enter” event happens at the time the app starts and no “exit” event is registered. The beacon is at 10 meters from the mobile phone.

I tried changing power transmission, and distance range from the app, but the results were the same. Apparently the range is too large, more than 10 mts.

Is there a solution to this problem? I need proximity zones of 5 mts aprox.
