Hi Mark,
I apologize for the delayed response on this. I have been trying to troubleshoot this further and get a clearer idea of the entire situation.
At this time, I cannot reproduce on my end, which is making this more difficult to get you all the needed information. Since I posted the original message, however, I have received 4 additional calls describing similar issues.
All-in-all, the users are complaining of bad accuracy. Either satellites will not connect, as described; or satellites will connect up and are shown in TMM as usual, but the horizontal accuracy is averaging around 20-60 ft and jumps around a lot, up to 300 ft sporadically. My users are using ESRI Field Maps with their R1s, and confirm their locations are displaying way off in the maps.
This is where some users are telling me that turning off location services fixes the issue, and allows the accuracy to settle in or connect to satellites, though honestly I have not consistently seen that to be the solution in every case.
I did confirm with my original user that his R1 would connect to satellites and receive positions successfully before connecting over Bluetooth. Once the GNSS light went green, he connected up to bluetooth, and things acted normally. I don't know if that's the solution, or if it just decided to work this certain time anyway - but I told him to keep me posted on future attempts.
I'm no expert here, but with my latest call, the user mentioned, "the lights are flashing green and they are supposed to be solid green." Something I wouldn't have picked up on, but after doing some digging in the user manual, I see this means that the receiver is sending autonomous positions, as opposed to corrected positions. I have no idea what this means, could you explain the difference, and if this could be affecting the accuracy they are receiving? If so, what causes it and how can I correct?
Again, I apologize because I feel there are a million variables here, and I was trying to narrow it down before replying; but I'm a little overwhelmed now and could use some external insight.
Let me know your thoughts or other things I could try,
Thanks,
Larissa

Hi Larissa,
This is strange. It would be good to confirm what happens if you take TMM out of the mix, i.e. switch R1 on and see if it acquires satellites without launching and connecting to the receiver with TMM. On iOS the location services are populated direct from the receiver over a dedicated 'channel', this should be unaffected by connected software. Indeed, R1 should connect to satellites and receive positions even when not connected to a device over Bluetooth.
Best Regards,

Subject: R1 Issue Connecting to Satellites when Location Services are ON
Hi all,
I was just notified of a weird issue a couple of my field users are experiencing with their R1 units. The workflow looks like this:
- Turn on R1 and connect to Bluetooth device. In this case, iPhone XR - iOS 14.4.2
- R1 will not connect to satellites. GNSS LED light flashes yellow. No satellites are shown in TMM. Tries to connect forever, with no success.
- User turns off Location Services within phone Settings.
- Connects again to R1 in TMM
- Satellites begin to connect, and GNSS LED lights flash green.
The R1 unit was just updated to firmware version 5.47, though this was occurring on 5.09 as well.
Anyone experience anything like this or have any thoughts? I must be missing some setting, or is some weird bug, but have had no luck troubleshooting myself.
Thanks!
Larissa
