Hi jomjol,

I tried to execute your code in VSCode - PlatformiO, but I could not get it to work. I always get the following error:

Kind regards FloSGM

Hi FloSGM, sure, you can post questions here of name me an email than I will contact you.

I have updated the master version to a working code. I used this to update it to a more eps-idf comapatible version. Mainly shifting the /lib to /components with addtional cmakelist.txt files
