Hi - I am using the W5500 as a Web Server and noticed that Chrome doesn’t always reply with FIN, ACK when the Web Server sends a “disconnect”. Instead, Chrome sends Keep Alive requests until Chrome is closed. Meanwhile, the W5500 sends an ACK for the Keep Alive packets even though the Sn_KPALVTR is set to 0. According to the data sheet, the automatic Keep Alive process should be disabled. I’m wondering if anyone has found a way to force the W5500 from ACKing Keep Alive packets?
EDIT: Never mind, my bad - I see the KPALVTR is for sending a Keep Alive packet, not responding to KA packets.
