Hi, My remote PC can't communicate with turtlebot3.

PC and Turtlebot3(R.Pi) can ping each others and ROS_DOMAIN_ID both PC and R.Pi is 33. But messages from turtlebot3 don't show on my remote PC using topic list. And I try to publish msg from PC but the msg don't show at R.Pi too.

And the firewall on both machines are disable.

What I'm I missing? Is there are any solution? please help me. thanks

do a printenv | grep ROS on both machine, to be sure that you have the same ROS_DOMAIN_ID on both. If you didn't put it inside the .bashrc, it is easy to forget it to type in any new terminal.
