Would you please tell us how to set up the W5500’s socket to receive two independent UDP packets from two different IP addresses?
Currently, I have opened one socket for a UDP protocol, and it works very well between W5500 and PC1. However, when I tried to connect PC2 to the existing W5500 via a switch, packets from PC1 dropped and sometimes W5500 did not even answer requests from PC1. Providing PC1 and PC2 have different IP addresses and are connected to the same switch/hub.
If I disconnect PC2, the communication between W5500 and PC1 will be re-established.
Thanks for your help.
