Hi All,
I’m currently attempting to get the Nordic’s nRF Cloud MQTT multi-service working on the nRF9160 Feather and could use some assistance. I’ve successfully connected to the nrfcloud but am having trouble retrieving GPS info from the GNSS; it keeps falling back to cellular.

Here’s the changes I made to the project in attempt to get working on the nRF9160 Feather:

Added circuitdojo_feather_nrf9160_ns.conf and circuitdojo_feather_nrf9160_ns.overlay from nfed/samples/tracker/boards to boards/
Added circuitdojo,psctl.yaml from nfed/samples/tracker/dts/bindings/circuitdojo,psctl.yaml to dts/bindings/

Next, I executed a build with the following command:

west build --build-dir c:\Git\nrfcloud_gps\build c:\Git\nrfcloud_gps --pristine --board circuitdojo_feather_nrf9160_ns -- -DNCS_TOOLCHAIN_VERSION:STRING="NONE" -DBOARD_ROOT:STRING="c:/Git/nrfcloud_gps"

console log looks like:
