Reply To: Problem with Pi3B and Bullseye

Is there any chance that the ublox has a binary protocol, and somehow it’s switched to that?

There isn’t a getty running on the port.  This morning I noticed that even with binary data on the port, gpsd seems to be working.

SOLVED…. I just ran “gpsctl -n” and it’s back to human readable NMEA sentences.

Have to wonder what caused the GPS receiver to switch into binary mode?

Thanks for the help!
