Testing the GNSS Module¶
The GNSS module has a dedicated serial port at
/dev/gnss0 depending on the version of the kernel in use.
If the module is not accessible via
/dev/gnss0 then it will need to be powered up first with a command like the following:
root@pureos echo 1 > /sys/class/leds/gps_en/brightness
The serial port operates at 9600 baud. You can use a terminal emulator to interact with the module:
root@pureos:~# picocom -b 9600 /dev/ttymxc1
It is also supported by higher level components. Applications should use those to interact with the module and obtain location information.
Modem GPS Module¶
There is an additional GPS module on the BroadMobi BM818 modem. However, it has been shipped without an an antenna for security reasons, making it inoperable.
