I have followed the following steps:

Both the sbc setup on the turtlebot and the remote have ros2 properly installed and can run turtlebot bringup. The only issue is upon connectivity between the remote and the turtlebot. The remote and the sbc do not recognize each other, thus any commands made by the remote are not received by the turtlebot. I am on the same wifi network.

Let me know if you have any ideas/solutions!

Have you tried the troubleshooting suggestion to check if multicast if working for you:

Hi Felipe,

I am the new Developer Advocate over at Open Robotics who just started last week. I am actually aware of this problem and we're looking into it (but we don't have a solution just yet). We're going to try changing out the ROS middleware layer and also looking at using an alternative Wifi chipset to see if that helps.

I'm really curious about how you felt about the documentation. Could you shoot me an email at the address listed in my profile?
