GPS module detected but not working RAK5005-O

Support

Got a new RAK5005-O, with a RAK4631 core, and a RAK1910 gps receiver.

When I boot the radio up connected to a computer running meshtastic --noproto i get the following message regarding the GPS:

DEBUG | ??:??:?? 1 [GPS] Since no problematic peripherals or interested modules were found, setting power save GPS_EN to pin 34

After the radio’s been on for 30+ minutes, I get the following in the log, about every 5min:
DEBUG | 01:49:51 2732 [GPS] Would normally factoryReset()

From what I can tell in the logs, as well as on the connected phone, the GPS module never communicates back to the main module, or gets a lock, its just spits out the above message.

The GPS module is currently in slot A, I’ve tried slot B but it wasn’t detected at all.

Any idea why the GPS isn’t showing up? Do I need to setup some firmware/software config to make the RAK4631 see it?

Currently running firmware 2.2.21
