We are still waiting for a solution that works on Android.
Google say Qorvo are “working on it”, but nothing yet…
The only UWB kit Google knows of that actually supports Android at the moment is MK UWB Kit Mobile edition 2.0, a €650 kit.
Hopefully Qorvo and / or Estimote (who use Qorvo UWB internally in their beacons) will come up with an Android solution soon…
