Hi,
I am using an m500 drone. It works/takes off flawlessly in Manual and Position mode. The drone does not take off while testing mavros test file.
I ran Ubuntu on VOXL using Docker following steps on this page: https://docs.modalai.com/docker-on-voxl/
Then, I installed MAVROS on VOXL by following the steps on this page: https://docs.modalai.com/mavros/
 
When I am testing mavros_test.sh or mavros.sh, the Drone does not takeoff. I have shared the image of the screen.
I don't understand these two messages on the screen:
1) Unexpected Command 520 
2) Requesting home position
I tested the whole procedure on two drones multiple times and I get those same messages every time.
