bno 055 gyro behavior on slowly rotation

[o_o]

For most applications, the NDOF mode will provide the best overall performance.

In case your robot rotates very slowly, you can use the COMPASS or M4G mode (both fusion modes also).

Are there any firmware which can solve that problem for bno055?

rotation speed from 0.07 to 0.64 rad/s
