I can’t make out any mistakes at the moment.
I’m not working on that project anymore and don’t have the hardware to do any testing at the moment, furthermore I’m in my exam period myself right now, that’s why I don’t have time to look further into it.
But here is my Version that I believe was stable and was working correct.
I hope that’s any help for you.
Best wishes and good luck!
