@kylebuttress Would you be willing to share the full code, I applied the initialization, but I remain having the same error.

The default testing code does not work, something seem to be wrong in "units/_uhf_rfid.py"

Changing the region does not help.
Removing the region just moves the error tot the automatiq freq hopping step.

Can someone help me figure out how I can find and edit the units/_uhf_rfid.py on the Core2?

Thanks in advance
