MAVSDK offboard set_velocity_body strange behavior



  • (Firmware 1.10, indoor parameters used)

    These set of MAVSDK code causes the drone to fly up approximately 5 feet and spin

    await drone.action.arm()
    
    await drone.offboard.set_velocity_body(VelocityBodyYawspeed(0, 0, 0, 0))
    
    try:
        await drone.offboard.start()
    except OffboardError as error:
        print(f"Starting offboard mode failed with error code: \
              {error._result.result}")
        print("-- Disarming")
        await drone.action.disarm()
        return
    

    My initial expectation is it would just stay in the ground. I'm just wondering what could be causing the issue, or how i can try to debug this. I'm getting odometry data in QGroundControl.

    Thank you



  • Hi Pey,

    Can you double check that the "offboard_mode" is set to "none" in the voxl-vision-px4 configuration file?
