So we’ve programmed the CORE2-ROS to our likings, we have also some ROS stuff on a PC to control it via a router. We were able to control the CORE2-ROS from the PC when a connection to the internet was made with a router.
Now we removed the internet connectivity to the router, I am still able to connect to the CORE2-ROS via the router and start the ROS code over there which connects to the ROS master on the PC. But a message from the PC is not delivered to the CORE2-ROS. How can we fix this?
Extra info: the CORE2-ROS runs a node, to which the CORE2 subscribers (emergency_stop topic). But because the master runs on the PC, it won’t receive those messages.
I was able to narrow down the problem: the CORE2-ROS does not read the messages published over topic to which the PC publishes. The problem happened when I removed internet connectivity from the system.
