This is jagadeesh. Recently i started working with W5500 chip. i downloaded drivers from site. TCP protocol is working fine but in case of UDP protocol data is not sending(sending without headers so other side unable to receve) but it is receiving. i checked with Wireshark then i found that data is sending from W5500 chip but it is sending without headers.so other side it is not capturing data. what are the causes for that. please provide solution for that. Thanking you.
