MAVSDK offboard set_velocity_body strange behavior

Pey Astig

(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?
