Hi,
I have the 7243 + LTE.
It should work for few minutes and than I turned off the ttn-gateway and the lora services for 30min and than back (all that in a loop).
After few hours the GPS stop working. also reboot of the RAK doesn’t help.
I tried to stop ttn-gateway service and run only the lora_pkt_fwd. Got the following messages -

also the GPS device is outside, the GPS cable looks ok, turn off and on the i2c from the raspi-config.
Thanks
