@ajb2k3 I tried some more test sketches with other Core units but the module doesn't seem to be available for any on UIflow. For reference this is the module I'm talking about.

@thefearface Lol. So it turns out changing which usb connection the cable was placed in fixed the issue. Everything works now with Uiflow. Weird. Thanks for the replies!
