Hello, I am using PX4 to control my drone with ROS2, and it is working. I am planning to build two drones, and I anticipate facing an issue in this part because having two PX4s means having the same topic names. When I researched this problem, I came across works done in simulation environments, and I tried them in simulation, and they worked. However, I am wondering how to achieve this in a real system. Can you help me with this?
I have reviewed the PX4-Autopilot software and attempted to modify the ‘dds_topics.yaml’ file located at ‘PX4-Autopilot/src/modules/uxrce_dds_client/’. However, the changes I made to the ‘topic’ sections in the file did not take effect when I attempted to upload it.
I downloaded the PX4-Autopilot software and solved the problem by adding different names to the uxrce_dds_client section in the “PX4-Autopilot/src/modules/uxrce_dds_client/module.yaml” file while installing.
resources: uxrce-dds-client
The parameter specified in uxrce-dds-client must be added and the namespace we want to add must be added.
