Ok, we’re getting somewhere. I was able to send raw after the changes. So I wonder what’s wrong with hex values.
Also I really don’t know…I think I need to reflash clean from scratch because now I am not receiving decoded messages as before on button presses. I reverted the changes you suggested but it’s the same.
Also while I like Platformio and that I can edit everything in VS Code I use on daily basis…the issues with unknown identifiers in *.ino files is just a pain…
