Hi, I'm trying to communicate between my Jetson TX2 and my laptop but can't see the topics on my laptop any idea how to debug it? Both devices are connected on the same wifi(I'm connecting and running the commands on jetson through SSH)

Jetson: export ROS_DOMAIN_ID=42 source /opt/ros/eloquent/setup.bash ros2 run demo_nodes_cpp talker

Laptop: export ROS_DOMAIN_ID=42 source /opt/ros/eloquent/setup.bash ros2 run demo_nodes_cpp listener

(No data received)

On other wifi network this one was working, so the problem is with the wifi, but what can I check?

Did you solve your problem. I have been installing ros2 recently and have the same problem with my PC and a raspberry pi IV. According to the tutorial it is basic stuff. I am wandering if it is not related to the router that is provided by my service provider. ( But i could be wrong.)
