Now, I need my already created (as per tutorial above) talker to send messages through some port that I could listen to, with the subscriber written in python, on Windows, without using ros. ![]() I can easily see sent and received messages. I created talker and listener as per tutorial:Īnd they work perfectly. ![]() I have the ros2_foxy set-up on Ubuntu 20.04 LTS via wsl.
