ROS2 - what is required from me?

[peredwardsson]

Hello,
I am running ROS2 Foxy on my robot, who I can access on my network, and whose topic show up when running ros2 topic list. However, no topics (or indeed any data at all) show up inside foxglove studio, which makes me wonder if I am missing something here.
I am running in a docker container with Foxy, where I followed the install instructions from https://foxglove.dev/download. I start foxglove-studio from inside the docker, open a panel for raw messages, and input a message which I can view via ros2 topic echo, for instance /localization/odometry/filtered, which is the output of my EKF node, of type nav_msgs/msg/Odometry. Am I doing something wrong?

Error message from terminal:
[1179:1213/122405.929485:ERROR:bus.cc(393)] Failed to connect to the bus: Could not parse server address: Unknown address type (examples of valid types are "tcp" and on UNIX "unix")
Robot has an IPv6 address - is that a problem?

It is a problem for now, yes. Our RTPS implementation only supports IPv4 currently. I created an issue (foxglove/rtps#13) to track IPv6 support.
