If you can make a board that connects GR-KURUMI and WIZ550io shield, it will fit in the size of WIZ550io shield (GR-KURUMI is layered under WIZ550io shield).
I tried connecting the TCP server program created by Viaual Studio on a Windows PC, disconnecting the LAN cable, turning off the power of the hub, and reconnecting properly. I also tried connecting to a TCP server created with an Arduino + WIZ550io shield. It worked fine in this range. A stricter LAN disconnection test may be needed.
Since there is no data reception for a certain period of time, I connect, disconnect, and reconnect repeatedly.
