Actually it does end with CR,LF according the sensor documentation:
I tried the readUntil with chr(10), chr(13) and chr(36) and none of them returned something other than the error in the picture in my first post.
I already wrote the code with the split and it doesn’t worries me too much, I know it will work with few experimentations. I just removed thqt as it was generating other errors since the reading doesn’t work.
I’ll try right now, the script without the try/except and report back.
Thanks for your help
