ROS Noetic networking, host is not set to this machine, tried everything
Really hoping someone can help me with this. I have a Raspberry Pi running ROS Noetic as a Master and an Ubuntu VM as the Slave and am trying to get them to connect. I tried the ROS Networking troubleshooting guide.
I can ping both ways by hostname and IP, ssh bidrectionally, and netcat bidirectionally. I tried ROS_HOSTNAME and ROS_IP and ROS_MASTER_URI by IP and hostname. Everytime I get WARNING ROS_MASTER_URI host is not set to this machine.
Here's a Youtube screen capture of me trying all of this with the same result each time. https://www.youtube.com/watch?v=y_0Jg...
Trying to get this working for a final project for my final Masters CS course. Would love to graduate! Thanks for any help.
did you source the bashrc after adding the export ROS_MASTER_URI = http://192.168..**:11311 ?
I realise videos can be convenient, but if (or when) your video disappears (and they tend to do that), there will be no information left in your question which future readers can use to determine what it was that you tried, and what happened.
It would be very much appreciated if you could at least summarise what settings you tried and what you observed when testing them.
