Neil,
If you would like to give me a call to clarify. I believe that you are correct about a BUG when using Android devices has recently appeared. I just tried to connect to a Trimble R12i like I used to through TMM and it will not ever appear. It shows scanning even though the device was already added in Bluetooth. I have a work around that seems to be working.
Here is a recent one that I have confirmed on several android devices. We recently sold several Trimble R12i's to different cities and water districts for both Trimble Access and Esri Field Maps.
Here is my old process that NO LONGER WORKS and work around.
Android Tablet Tap Bluetooth; add a device and find the Trimble R12i and connect.
Launch Trimble Mobile Manager and under position source list the Bluetooth devices and pick the Trimble R12i
GNSS configuration change from Auto to Custom Local and key in Direct or NTRIP settings
Connect and under status verify that everything is working and that your correction source is coming in and its latency.
Close TMM and know that everything is now setup properly for Esri Field Maps
Here is the only way that I have been able to get a Trimble R12i to work under current TMM and Firmware and Applications on Android
Android Tablet Bluetooth add a device and find the Trimble R12i
Launch Trimble Mobile Manager and under position source list the Bluetooth devices (It will never find the Trimble even though you just added it under Bluetooth. You can even go back into Bluetooth settings and confirm it is connected…so ignore this step)
GNSS configuration change from Auto to Custom Local and key in Direct or NTRIP settings
Connect and under status verify that everything is working (since you can't find the Trimble R12i, you can no longer verify this using TMM…skip this step)
Close TMM and know that everything is now setup properly for Esri Field Maps
Launch Esri Field Maps
Make sure that Provider shows Trimble R12i or click add and you will see the Trimble R12i available and add it and check it to be current.
Verify you have built a proper Profile from GCS NAD 1983 2011 to WGS 1984 Web Mercator Auxiliary Sphere and chosen the WGS_1984 (ITRF08) to NAD_1983_2011
Launch your Map Card and watch the Trimble R12i work properly under GPS Details
Crazy but it works… Field Maps is just making a call to pull the GNSS configuration from TMM so as long as that was set correctly it works. Not ideal and NOT the way it used to work.
