Oh man. , thank you so much that was the issue

(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

(Firmware 1.10)I have the indoor PX4 parameters uploaded to the drone in QGroundControl.
One possible source could be that the sensor calibration I did wasn't
perfect. But I believe that since I'm using indoor PX4 parameters, position flight mode depends only on the Tracking Camera (external vision) and not the sensors ?

Thank you, this helped a lot.

For example, does having VIO to True, simply set PX4 parameters to use External Vision for EKF2? Do I have to change VIO and VOA to false if I'm doing an outdoor flight test?

The reason for the question is it would be helpful to test software command API's on the VOXL-m500 such as MAVSDK more intensively without risking accidents
