Worked on the Auterion/px4-ros2-interface-lib repository to enhance stability and interoperability for PX4 ROS 2 deployments. Focused on resolving a namespace handling issue in the waitForFMU function, the developer improved message compatibility checks by ensuring topicNamespacePrefix() and _topic_namespace_prefix were correctly passed in mode.cpp and mode_executor.cpp. This targeted bug fix reduced runtime errors and improved end-to-end integration reliability without introducing new features. The work maintained API compatibility and reduced integration friction for users. The project leveraged C++, embedded systems expertise, and ROS, emphasizing robustness and maintainability in the PX4 ROS 2 interface library during the development period.
