  • Calibration for VOXL SDK 1.1.3
    Phi NguyenP Phi Nguyen

    I did upgrade the RB5 Flight with VOXL SDK Platform 1.1.3.
    When I try to calibrate the IMU, it happend:

    rb5:/$ voxl-check-calibration
    Calibration File Status:
    Missing /data/px4/param/parameters_mag.cal

    rb5:/$ voxl-calibrate-imu
    ERROR: in json_read_file, config file is empty or unreadable

    ERROR: Malformed calibration file: /data/modalai/voxl-imu-server.cal
    Please make a new calibration file with voxl-calibrate-imu

    ERROR: Neither IMU pipe appear to be open
    Make sure the voxl-imu-server service is running and try again

    and

    voxl-imu-server | Enabled | Not Running

    After calibration with QGroundControl, I realized that the orientation was wrong, I do not exactly which orientation is, it was mentioned in this link https://docs.modalai.com/px4-calibrate-sensors/ is:
    When you click on the Compass or Accelerometer calibration buttons, QGroundControl rightly asks you to confirm the board orientation. If using the PX4 master branch or the ModalAI build 1.10 then use ROTATION_NONE. The default orientation in the parameters file you uploaded before takes this into account. NOTE: the 1.10 release from PX4 for Flight Core is not recommended as there have been fixes including a orientation change.

    Thank all!
