I recently gave an online webinar to explain all the details of the new Zenoh bridge for ROS 2. Here is the recording: https://www.youtube.com/watch?v=-WZAA35jLxc
Starting from 25:25 I explain how to easily setup the Turtlebot4 with this bridge and get RViz and teleop over WiFi (or over the internet thanks to Zenoh!)
If you have any question, I can answer here or on our Zenoh Discord server.
