Hi All,
I too had problems getting our location accuracy (bottom left corner of Collector screen) and the blue dot (user’s location) to show up after I selected the Trimble Unit (R1) as the Collector App's "Provider" in Location Settings. I am glad that the GNSS overwrites the GPS no matter what the application displays, however I want my users to be able to know their accuracy while they collect data.
By adding some GNSS Metadata Fields to my feature service in AGO, I was able to get the blue location dot to show up, as well as see my GNSS accuracy.
Step 1: Add some (not all are needed) GNSS Accuracy Metadata Fields to points feature class in AGO, save web map
Step 2: Open iPad settings, connect Bluetooth to GNSS receiver
Step 3: Open GNSS Status App (iPad, Android) and connect to GNSS receiver
Step 4: Open Collector and change “Provider” settings to your GNSS receiver instead of the Integrated Receiver, this will make Collector ask if it can open the GNSS Status App, allow it to do so
Step 5: Open Collector Web Map, it should zoom to where ever you are and you should see your location dot as well as the GNSS receiver accuracy
My experience is that feature services without the GNSS accuracy fields do not allow the GNSS receiver to be the “Provider” in the locations settings. Follow my link above and add the GNSS accuracy fields to your feature service (you can do this in AGO so you don’t have to re-publish the service), then try making your GNSS receiver the “Provider” in Collector without any issues.
I hope this works for you!
