Description

This parameter sets the destination UDP port for the Data Distribution Service (DDS) interface, which allows ArduPilot to communicate with ROS 2 (Robot Operating System).

• Function: The autopilot acts as a DDS client and sends telemetry to an external agent (like Micro-XRCE-DDS-Agent running on a companion computer).
• Default (2019): This is the standard port for Micro-XRCE-DDS.
• Config: Ensure your companion computer is listening on this same port.
