Thank you again for the reply!
We are setting up a multi-robot system, so we are using ROS_LOCALHOST_ONLY=0.
For example, we want to set the ROS_DOMAIN_ID of drone 1 to 1 and the ROS_DOMAIN_ID of drone 2 to 2.
However, for both drones, PX4-related messages still appear under domain ID 0.
Have you tried this with two or more drones?
