Location Services

The GNSS module has a dedicated serial port at /dev/ttymxc2, operating at 9600 baud. You can use a terminal emulator to interact with this device:

root@pureos:~# picocom -b9600 /dev/ttymxc2

It is also supported by gpsd.

Modem GPS Module

There is an additional GPS module on the SIMCOM modem. This modem is not meant to be used on the final phone. It has been shipped without an an antenna on the development board, making it inoperable.

GNSS on the Phone

On the Librem 5 phone itself the GNSS module is accessed via a different serial port. See Testing the GNSS Module for more information.
