Bumping this thread because this is is turning into a real problem.
Using iOS last week, I got into FieldMaps and had precision of about 70cm with the R1, which was expected. I
watched it switch from 70cm to 2.1m before my eyes. This happened two or three times.
I ended up using Collector for rest of the day, which gave me no problems.
Given the precision shift, it appears to me that FieldMaps is dropping the R1 entirely and switching to the integrated provider.
The configuration chart indicates the two apps handle the connection differently, which may explain part of the problem.
That being said, I'm cross-posting this to the Esri Community and am interested in hearing if other people have this issue here.
Thanks!

Hi Alfred,
Each of the three data collection apps you use interacts with TMM differently, so you will see different behaviour.
- Field Maps: Use TMM to configure the correction method and coordinate system/Geoid. Once you have done this TMM should be disconnected from the receiver. Field Maps uses the configuration you set up in TMM, however it does not need TMM to be connected to the receiver while it is running, indeed you are seeing TMM disconnect by itself because Field Maps and TMM cannot be connected to the receiver at the same time.
- Survey123: On iOS Survey123 consumes an NMEA stream direct from the receiver, TMM is needed in this configuration to feed corrections to the receiver and you should not see TMM get disconnected. You do need to make sure that your R1 firmware is up to date for this configuration.
- TerraFlex: TerraFlex does not use TMM at all, all receiver configuration and management is done by TerraFlex itself. It is not possible to have TerraFlex and TMM connected to the receiver at the same time, so it is correct that TMM shows as disconnected.
I'd recommend you look at the Product Configuration Guide here.
If you continue to have issues it would be worth contacting Trimble Support directly.
Best regards.

Hi all,
I've been having an issue with TMM (2.9.0 iOS) where it will lose connection to my R1 at the drop of a hat.
I'll go through all the steps to connect, and using a RTK it'll get down to 55ish cm. I'll open my collection app: either Arc GIS Field Maps, Survey123, or Terraflex, and the precision will drop to 1 meter.
When I go back to check, TMM says that it isn't connected to the R1, but once I flick the switch, it'll get back to normal.
I will then have to relaunch my collection app, after which I might get one point in before it acts up again, or it might not get fixed at all.
Does anyone have any idea what's causing this, or how to get around it?
Thanks!
