I’m having some issues trying to use W5500 as modbus TCP client. It seams to be that I can write wiz_NetInfo via SPI to the chip by using wizchip_setnetinfo(&netInfo) because I can read back the written things by using wizchip_getnetinfo(&netInfo).
But I am unable to connect to slave device. Function “connect(s,slave_ip,502)” did not respond with 1 as it should be?!
I also tried to capture the response message, I hope that helps and you can give me a hint to fix this problem
