BNO055 Y-axis linear acceleration drifts after a while

[Justin]

Hello,

We have been using bno055 sensors to get data about footsteps, so we have been testing it and acquiring data in NDOF mode and got the different linear accelerations values out of it. Once, I was walking for a long time, and all seemed fine except at one moment the Y-axis linear acceleration started drifting. Then, after a break where I didn’t walk it started working fine again.

I’ll join the graph that was made out of this test, so you understand what I am talking about.

Does anyone have any idea why it is doing that?

Thank you in advance.

Hello Justin,

Could you provide log file that included x, y, z axis RAW data?
