There’s a problem with the GPS on some of the T-Beams which means it stops outputting NMEA on the serial port. I had this recently. You can see the red light on the GPS flashes (which shows it has a lock), but any of the GPS sketches return no results.
I was able to get mine working again by running the second of these scripts, they basically reset the GPS and make it send out NMEA again.
is this still needed? another thread mentions that this reset was not needed/ in a new firmware version? I have this problem with m8n gps on a tbeam 1.1. I only know the web flasher.What’s the next programming? python CLI or something?
