MAVSDK on local laptop

[dvPr1m3]

Hello,

I have a Starling V2 drone and have been able to successfully execute the automated takeoff and landing MAVSDK example as described here:
https://docs.modalai.com/mavsdk/#mavsdk-on-voxl2

The drone is in station mode and both the drone and the ground control station PC (which is a laptop) have IPs assigned to them. I am able to ping the laptop from the drone and vice versa. QGroundcontrol works fine on the laptop. The laptop runs Ubuntu 22.04.

I am looking to now deploy the same take off and landing example but executing it from within the laptop (instead of using the docker container on the drone). I used the Dockerfile within https://gitlab.com/voxl-public/voxl-docker-images/voxl-docker-mavsdk.git as my reference to install the required packages for mavsdk and was able to build and install mavsdk and the C++ examples. However, when I try connecting to the drone at the IP and port 14550, MAVSDK is not able to connect to the drone.

Any help would be greatly appreciated. Thanks!

I got this working. I initially had the following in the takeoff_and_land.py script which did not work:

await drone.connect(system_address="udp://192.168.1.44:14550")

where 192.168.1.44 was the IP address of the drone, but when I changed it to the line below it worked!

await drone.connect(system_address="udp://:14550")

The IP address of my laptop is 192.168.1.100 and is listed as "primary_static_gcs_ip" in /etc/modalai/voxl-mavlink-server.

My question though is how does the script on my laptop know that the drone is located at 192.168.1.44 in the second case and why does the first case where I specify the host within the connect() call not work?

Thanks!
