You definitely need to clarify what you mean, what you do (with W5500), how you do it and what you want to achieve.

Hello, @023-Mohammad_Syawal normally, udp did not check destination status. If you want to send udp data to multiple destination, you also need to make send command multiple times. (if you are not set udp multicast or broadcast) And there is no timeout concept in udp… could you also check why destination make timeout?
