No GPS on T-Beam V1.1

Support

Hi everyone,

I just get 2 T-Beam V1.1 w/ NEO-6M and I just flash them to the latest version of meshtastic (0.9.1)

I get a “no sats” status on both of them…

I let them outside for several hours and still nothing .
I get nothing in the map inside the app.

How to fix this ?

Can you connect to the serial port of the device and capture and post the first 50ish lines it prints? (921600 baud)

You can find the log here :

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?
