I am in the process of building a backup SensorGnome. The last one had a SixFab hat and the GPS worked right away, but I gave up on getting its’ cellular connection to work. This time with the Waveshare hat the cellular worked on boot-up but but I’m having no luck connecting to the GPS.
I suppose another option would be to change the time synchronization to point to a server instead of the GPS.
If your SG is connected to the internet it uploads the log files and I can take a look (if you provide the ID…).
You need to have a SIM card inserted to have the GPS work. This will be fixed in the next release but I can’t finish that at the moment.
The SIM card is in place and cellular network connectivity seems to be quite good. However the GPS is still showing as No-Dev.
I haven’t set up this SG-EB6ARPI3AEC0 as a receiver yet since I’m not sure how to configure it as being just a unit under test. Create a station called “test-bench” in our project maybe?
I’ve attached the log file below.

Thanks for the logs! Unfortunately the Linux ModemManager doesn’t recognize that the SIM7600 has a GPS. I seem to remember that this was a problem in that version of MM. OIf you have the patience to install the latest SG dev build that would answer the question whether it’s fixed in a more recent version. You need to reflash an SD-card for that.
If you simply go ahead using NTP keep an eye on the data transfer charges.
