ROS2 connecting nodes
UPDATE! I accidentally had one extra network cable connected to Raspberry PI from previous task. This did not work work through WIFI as planned. For some reason, the multicast group 239.255.0.1 did not work. This is how it's supposed to work, but did not always work in my default environment. The functionality over WiFI in my network does not seem fully consistent. What and why? In this blog entry, I document my attempt to run two nodes for ROS2 foxy2. I have Intel NUC computer and Raspberry PI4 connected, both are connected via wifi AP. Both are running Ubuntu 20.04 Before doing testing this, I learned the fastRTS profiles use multicast group 239.255.0.1. Goal was to see two nodes talking.
