i've followed all instructions from calibrating the tracking camera
https://docs.modalai.com/calibrate-cameras

to 
https://docs.modalai.com/voxl-m500-user-guide-using-vio

i've configured every setting with voxl-configure-qvio and still get the following error

voxl2:/$ voxl-inspect-qvio
waiting for server

 dt(ms) |    T_imu_wrt_vio (m)   |Roll Pitch Yaw (deg)|features|quality| state| error_codes |
   30.9 |    0.00    0.00    0.00|   0.0   -0.0    0.0|     0  |   -1% | FAIL | IMU_MISSING STALLED

any ideas?

@sansoy what is the output of `voxl-inspect-imu`? It looks like qvio is not receiving the data from the imu server. Did you configure imu-server? Or is this all out the box for the m500?
