We have a pair of R2s with Collector and two Android tablets. This may not really be a collector topic but thought I would start with this community as its a great resource.
On one of the tablets, GNSS Status App connects to R2 and receives corrections service (NTRIP) for a few minutes. Then GNSS Status App loses its connection to the R2. Logging into R2 Web UI I see everything is running and positions and corrections are being computed. The R2 continues to flash green but GNSS Status cannot reconnect.
Rebooting the R2 will reconnect again but then fail after a few minutes.
