I am working on unit 1 of the Mastering with ROS: SUMMIT XL course. The last exercise asks to publish the waypoints so that the shape of a circle/8 will appear. I am publishing them with a for-loop in Python one after another with a time.sleep(1) in between and some of the waypoints are not published due to Inbound TCP/IP connection failed.
Here is the warning that I get:
[WARN] [1605710219.235047, 8432.001000]: Inbound TCP/IP connection failed: connection from sender terminated before handshake header received. 0 bytes were received. Please check sender for additional details.
I already searched in the web but I could not find the solution. I changed the buffer size of the publisher from 1-25 and it did not change anything and increasing the time.sleep() time also did not work.
Any ideas how I could solve this issue?
