<![CDATA[Unable to calibrate compass on VOXL CAM w/ Flight Controller]]>Hi, I"m just finished to mount the voxl cam w/ fligth controller on my frame and did all the connections.

It ask me to setup the frame which is a generic X, and ask now to calibrate the sensors. All is fine for the Gyro and accelerometer, but I tried several times to calibrate the compass and didn't work. I let the rotation angle to NONE.

Do I should setup a Rotation angle before to calibrate the compass?

Thanks for your answer!

  1. With Rotation None, the QGC see my aircraft on left side instead of level position, and so on.
    When I test to arm and take off, it see the vehicle as turn on right side and have failsafe issue.

  2. If I put Rotation = Roll 270 is much better, and I can arm and takeoff (just simulate for now).
    Still, I have two positions that are not right, aka it show the vehicle on:

  • left side instead of noise up
  • right side instead of noise down

I would really appreciate your help to indicate me the right value for the Rotation to well calibrate this sensor.

Thank you!

That's normal then, because I didn't attach a gps to the board. My intention is to use it on indoor.

Have you connected a supported GPS/Mag unit to J10? See details here: https://docs.modalai.com/flight-core-datasheets-connectors/#j10---external-gps--magnetometer-connector
