Upgrade to Reachview 3 and got lower frame rate and error message

[spcrobocar]

I have been using this repo for my Reach RS+/Reach M+ pair and it worked well. I could get RTK 14 frames per second.

However, today, I upgrade my iOS app to ReachView 3 and it, to my surprise, also upgraded my M+ firm ware. Now I only get 1 frame per second, and a lot of warning messages like this:

Regex didn't match, sentence not valid NMEA? Sentence was: '$GBGSA,A,3,,,,,,,,,,,,,17.0,2.8,16.72C'
[WARN] [1651443826.909854]: Regex didn't match, sentence not valid NMEA? Sentence was: '$GBGSA,A,3,,,,,,,,,,,,,17.0,2.8,16.72C'
[WARN] [1651443827.902889]: Regex didn't match, sentence not valid NMEA? Sentence was: '$GBGSA,A,3,,,,,,,,,,,,,17.0,2.8,16.7*2C'

How can I fix this?

Do you have a screenshot on how you configure it in the app? What is the output configuration look like?

This is the RTK setting

This is "Position output" settings.
