I have installed Unified Firmware 2.2.1 on a RPI Zero W.
previously an older version was installed and I could use GPIO 23 for the stations
With the new version GPIO 23 doesn’t work
Do I have to set something?
If you are somehow on the 2.2.1 minor revision 1 branch: that’s an un-released firmware, where pin 23 is used for a button so is no longer in the free pin list.
