This is an ESP32 that is going to be working as a TCP Slave device so someone else can connect to it and get the data from the registers with an HMI. While configuring and checking IP Addresses, I noticed tha...

Hello, I have been trying to get Modbus TCP to work through SPI Ethernet interface. I am able to start processes successfully but I have some questions about the different IP addresses. It is obvious that both the w5500 module and the ESP32 have different IP addresses, the problem is that I'm only a...
