Hi. I want to communicate between two (or more) MCUs (one side is server and others are clinet) in UDP protocol with using TCPnet. First of all I write a code to transmit data to PC and it worked well. Then I write a code which in, MCU receives data from PC program. The above codes work correct. but when I connect two MCUs to each other, I cannot receive data in server side. I checked the IP and port in both sides. also MAC address in both sides are different. has anybody an solution for this problem. PHY IC is DP83848CVV.
