Hi Jim,
All the code is in hermes/quisk_widgets.py.?
Does the 0xEE appear in the ATU control window? When it does, the "Spot" button should be pressed and red. Is it??
As your code operates, the codes sent from register REG_ANTENNA_TUNER should appear in the control window, and that is a good start for debugging.
