I spent quite a few days to get the BMI270 API tamed. .... No luck. It always returns with rslt:-9 Error -9 : Configuration loading error which comes from the internal status -- message: 2 - init error. Anyway it was just part of my problem.
A lot of people have similar issues as I can see - and I understand them. Could you please help us out and put together a minimalistic yet working repository to overcome this steep bump.
