RVIZ drops 100% of messages
rviz has been dropping 100% of broadcasted messages despite finding the published nodes and subscribing to them. It has something to do with my ROS_IP and ROS_MASTER_URI because it works fine when ROS_MASTER_URI is not set.
Here is an example situation to reproduce my error:
In three terminals do:
export ROS_IP=<my ip="">
export ROS_MASTER_URI=http://${ROS_IP}:11311 // this works, it looks like: http://10.0.26.191:11311
then in one terminal run roscore, in another launch a camera node, and in the last run rviz.
Despite the fact that I can use image_view to see the images from the camera node, rviz can't receive any of the messages.
I am trying to broadcast messages across a network and visualize them with rviz, which is why I have this setup.
This sounds like a networking issue. I'd recommend just using
rostopic echo
(rather thanrviz
) to simplify things. I'd also recommend trying to usenetcat
to test your network settings: http://wiki.ros.org/ROS/NetworkSetup#...The thing is, image_view can receive the images while rviz cannot.
