python3 and nextion.py

[KN2TOD]

How is this supposed to work? What am missing here?

I'm assuming that this version of nextion.py (under Bookworm in Pi-Star 4.3.0) is supposed to allow me to update a Nextion display's firmware while it's still attached to the HAT - in situ, correct? (Currently, it's a pain disassembling, unplugging, inserting a microSD, etc. just to make a firmware change!)

Do I need to stop the NextionDriver and MMDVMHost tasks first? Or is there a config setting or parameter somewhere that's missing or incorrect?
