sorry I hadn’t noticed this thread before. Meshtastic has always switched the ublox GPS into ubx protocol mode, because UBX has a lot of advantages over NMEA. Both UBX and NMEA work over serial, UBX is just a different protocol. The ublox stores which protocol to use in its battery backed up ram.
If you’d like to use a different project you’ll need to switch it back (I haven’t written any code for this because this project didn’t need it). Someone just asked for something similar in this bug: https://github.com/meshtastic/Meshtastic-device/issues/334
I need to fix a few bugs first, but in the next couple of weeks I can add some sort of “switch GPS back to NMEA feature (somehow)”
