I am attempting to communicate between multiple Arduino Uno. I have W1500 ethernet shields and an ethernet switch. I first want to simply transmit from one arduino and have it received by the other.
I have had a couple of cracks at using existing examples, such as UDP Send Receive String, but I have never managed to be able to receive any messages, only transmit.
Has anyone had this going before? Or is it even possible?
I just want some tips on what direction to take to get some form of communication between the two. With this start, I feel I may be able to scale it up.
