The PX4ros package that comes with MRS conflicts with the native PX4 software package simulation

[yuan99993]

Hello author, I have recently been attempting to integrate MRS into a multi-vehicle environment. I found that MRS is not suitable for fixed-wing aircraft, so I used the native PX4 package to import the fixed-wing. However, I discovered that without removing the MRS-provided PX4ros package, my fixed-wing cannot automatically switch to OFFBOARD mode. Once I remove the MRS PX4ros package, the fixed-wing can switch automatically. Could you explain why this happens? Additionally, I have noticed that the MRS PX4 package conflicts with the native PX4 package. I would like to know how to avoid this situation.

Hey, the PX4 does not provide official ROS installation. So I suppose you are compiling your own?

We compile our custom fork of PX4 and installing it as a deb package. If you want to use your compiled version over ours, you have to make sure your workspaces are setup properly, such that the compiled version is preferred. That means, in ROS2 for example, to set allow-overriding in your coldon_defaults.yaml.
