Hi,
my guess is that you are still connect in Trimble Mobile Manager - while you want to connect with ESRI Collector.
The antenna connection is a 1:1 resource on your Android phone. In other words only one application can use Catalyst at a given time - or you share the position via Android mock locations.
Could you please double check:
- In TMM, connect to Catalyst
- Verify you get a valid position (just to be sure)
- Disconnect in TMM (so that the Catalyst service icon on the upper left disappears).
- Switch to ESRI Collector
- Configure Catalyst as location provider
- Go into the map view (where the error message showed up before).
The Catalyst service icon should appear in the upper left corner plus a position should be available soon after.
Regards
Nico
