dds_topics.yaml — PX4 Topics Exposed to ROS 2 ​

INFO

This document is auto-generated from the source code.

The dds_topics.yaml file specifies which uORB message definitions are compiled into the uxrce_dds_client module when PX4 is built, and hence which topics are available for ROS 2 applications to subscribe or publish (by default).

This document shows a markdown-rendered version of dds_topics.yaml, listing the publications, subscriptions, and so on.
