Change px4 sitl gazebo ports for gcs and API

MAVLink
1

I want to run two commands like these back to back

make px4_sitl gazebo_plane 
make px4_sitl gazebo_standard_vtol

The idea is to eventially have them work on following

Plane: 14550 (GCS), 14540 (API)
VTOL : 14552 (GCS), 14541(API)

so that at the same time, I can connect them to GCS, and be able to programatically connect them via mavsdk-python code and control them via code. They both need to work together, which is why I want them to be simulated together, and have to be on same GCS.

How do I accomplish this? I’m using ubuntu btw.

You need to start it with different instances.

For old/classic Gazebo there is a script:

With new Gazebo (Gz) it’s easier and you can just start individual instances using the instance argument:
