[Elphel-support] Fwd: expected imu data fortmat

[support-list]

Hello Hamid,

Did you make the IMU work and now just trying to optimize parameters, or it does not work and you try to make it work at at least lower rate?
If it does not work - please send the camera to us, we'll look at it, if you try to change the IMU rate - I am not sure if everything will work as expected as we tested IMU only at the maximal (nominal) rate. Why do you need to reduce the rate?

Andrey
