ROS2 - Switch Between Different DDS Implementations (Fast DDS, cyclone DDS)

[@YuzheWu-e7i]

Do we need to recompile the ROS2 node with new DDS? Or the previous built ROS2 node can directly run with new DDS?

Good question. You should not recompile, just source the correct environment variable.

So if I remove the export command from the bashrc it will use the default DDS again?

[@RoboticsBackEnd]

Yes! Make sure you open a new terminal so that the change is effective.
