I get this error systemd-udevd[89565]: /etc/udev/rules.d/gps.rules:2 Invalid key/value pair, ignoring.

Or is there an easier way to do it

Hi @MattyR I would suggest you test the udev rule is valid on a standard distro, maybe using a container or a virtual machine, and once you verified it works then add it to the balenaOS config.js. BalenaOS is not the friendlier platform to debug this as it’s a lightweight OS specialized in running container workloads.

Device it out there with the modem in it now. Can’t have access to the modem for testing
