UDP echo server

Cool project! 👍

I got the sample 20 to run without any issues on RPi4. Thanks for the samples, BTW!
Before I dive into the sources and try to figure it out on my own, did anyone make a UDP version of that echo server by chance?
Even if someone has a hacky mod of sample 20 for UDP would be enough to get me started.

Thanks!

I managed to hack tcpsimple sample by looking a the tftp client code to get the UDP version of echo server.
