How to access GPS data in Mobian - ragreenburg - 05-08-2021
Anyone know how to get the GPS information from the GPS in the PinePhone? I've tried a few programs to get the location but they all seem to go by IP address so they all basically just say the town I am in and are off by a few miles so I was hoping to get the actual information from the GPS itself but I don't know how to do that. I also tried 'whereami' and for some reason that doesn't work. I install it and it says I have the most up to date version then when I try to run `whereami` it says the package isn't installed.

You could install gpsd and run one of the clients. xgps works but is not optimized for the screen. The text based clients gpsmon and cgps will give you all the typical GPS statistical information. The NMEA output that gpsd needs is on /dev/ttyUSB1. The config file is in /etc/default/gpsd
The antenna is very weak and it will take a long time outdoors even with a clear view of the sky to get a lock. You will want to run the AGPS proof of concept script to speed up the initial lock. https://gist.github.com/alastair-dm/263209b54d01209be28828e555fa6628
You can also talk directly to the modem via AT commands to get a location manually, It is what the AGPS script uses. https://sixfab.com/wp-content/uploads/2018/09/Quectel_EC25EC21_GNSS_AT_Commands_Manual_V1.1.pdf

The config file is in /etc/default/gpsdThank you for the information! Quick question, as I don't have my PP on me right now to test, with the AGPS it says to run `AT+QGPS=1` to start the GPS, is that just ran in the command line? I don't have any real experience with working with modems in general though I do have experience with a handful of programming languages.

If you run the AGPS script it turns GPS on for you so you don't need to do any manual AT commands.(05-08-2021, 08:52 PM)8bit Wrote: You could install gpsd and run one of the clients. xgps works but is not optimized for the screen.

If the AGPS script gives serial errors you probably need pyserial
sudo pip3 install pyserial
