Hello,

We have a couple of biologists using Field Maps and Garmin Glo units for use with the tracker extension. They are using iPad Pros and work offline. Field Maps and Tracker apps were both uninstalled and only Field Maps is now installed on both devices. The uninstall/reinstall did help one device in now tracks actually show on the map within Field Maps and they were able to collect tracks for about 3/4 of their survey. The other device briefly had tracks offline but then was never able to get the tracking layer to show in Field Maps. I'm attaching the tracking log for help in interpreting the errors for the device that never saw tracks in the map.

10:00 They downloaded an offline map and were in WiFi range for testing/training

12:00 they went offline (left the office)

3:00 returned to the office after aerial survey

In the attached log: I see these messages and don't know how to interpret

12:07 [TRACKS] Location Manager failed: The operation couldn't be completed. (kCLErrorDomain error 0.) this error can be found in numerous places

12:26 [TRACKS] tracks fail-safe timer triggered  (error also found throughout)

They tried to disable/enable tracking to see if this would resolve the issue @ 1:11, but no luck.

In the user settings, the receiver shows the Garmin Glo (updated with latest firmware) and has a good accuracy < 5m but they have consistently had issues with getting the tracks to be visible and then reliable. 

Interpretation of the errors above would be appreciated and any troubleshooting help to get their tracks working would be appreciated.

Thanks,

Kathy

This usually means core location services on the device failed to get a location for some reason.

12:26 [TRACKS] tracks fail-safe timer triggered (error also found throughout)

This means there have not been new locations within the last 60 seconds, so a timer expired and is updating the last known location feature of the user with new attribute information even though the geometry/location has not changed.

I don't have much other advice other than maybe restarting the receiver and/or phone.
