Quaternion NaN???
I have two same sensors. One works well with acquiring the data. The other one has following information.
Sensor Quaternion = {w: NaN, x: NaN, y: NaN, z: NaN}
the Sample APP provided (sensor fusion) also cannot catch anything
What is wrong with this sensor?

Post the platform, relevant code, and device information of your setup.
Does the board in question work with MetaBase?
No data shown on MetaBase. I reset it, it seems to work normally now. however, why the w value is very close to 0.1.
What's wrong with the w component being close to 0.1?
After reset, it is close to 1 now
on the same topic, we are getting NaN from time to time on the field. Reset seems to solve the problem, but question is, why it happens?? obviously NaN can be detected by the software, which then can reset the board, but NaN might be just a memory overflow problem, that could manifest in giving non-NaN, totally erroneous numerical values. This is worrying.
We would love to hear any ideas
thanks!
