Please use branch 0.1.6-final, do a git pull and create a debug package. See https://wiki.bambuddy.cool/features/system-info/?h=debug#enable-debug-logging

@BalazsCsutar222855 Did you enable Dev-Mode? That's very important.
Branch 0.1.6-final is successfully checked with A1 and P1S printers

Lan-Mode and Dev-Mode needs to be enabled

I have built everything from scratch once again, and now it works. I must have made a mistake somewhere down the road. Thanks for helping out!
