I am trying to switch the transport of ROS2 humble from UDP to TCP, so I set the environment variable
FASTDDS_BUILTIN_TRANSPORTS to LARGE_DATA, but now when I run the publisher node the topic to which the publisher publishes does not show in ros2 topic list
What I did was running a ROS2 publisher node in a ubuntu machine and tried to list the topics in the same machine in another terminal. the topics are not listed in another machine in the same network with the same ROS_DOMAIN_ID
