I'm having problems with GPS. It shows my location as 50km away from where I am currently located.

It looks like location is hooked in via the ModemManager. When I follow the manual page for mmcli to get the location at the command-line I'm getting some weird results.

Code:

debian@pinephone:~$ sudo mmcli -m 0 --enable      
successfully enabled the modem
debian@pinephone:~$ sudo mmcli -m 0 --location-status

Where's the code for the custom ModemManager? I could have a look and see if I can figure out what goes wrong in my case.

Thanks,
Chris

Is there a way to disable auto-brightness? Nice feature, but drives me crazy.

Thanks!

GPS is not a super strong signal anyway, I have seen it lose lock, or fail to acquire, in well shielded locations like metal buildings or even in heavy forest with little view of the sky.

Note in your code above, line 7:   signals :   no

Yup, Settings, Power

Thanks wi_badger, I'll give it another try outside over a longer period. It's good to hear that it's working for someone else, so maybe the problem is just on my end.

Note the NMEA output in my original post though. The output looks like it is corrupted compared to the sample in the mmcli manual page on the wikipedia, which shows that there are supposed to be values like "$GPGGA,092750.000,5321.6802,N,...".  There is no gps raw section at all.

Do you know where the source code is for the custom modemmanager for this image?

Chris

That way does not work. That was my first move. The slider goes to the right, but remains blue and nothing changes.

But I remember it working quite well in an earlier version. I don't use it often enough to know when it stopped working for me.
