i walked through this tutorial.
After flashing the ROS code on my CORE2 i get this Error when i want to run the rosserial_python script:
“[ERROR] [1596637530.319359]: Error opening serial: [Errno 2] could not open port /dev/serial0: [Errno 2] No such file or directory: ‘/dev/serial0’”
i have an CORE2 with an Raspberrypi.
I also tried to change the ports but it didn´t work.
What can i do to see the topics and nodes which are running on the CORE2?
