ESP32-WROOM-32E Modbus TCP Client/Server

[sunasrariyaz]

Hi,

I have an ESP32 dev module which has ESP32-wroom-32e and LAN8720A-CP as PHY connected to the J0011D01BNL Ethernet Port. This is the hardware.

The connections from ESP32-wroom-32e to the LAN8720A-CP PHY are as per default connections.

I want to use the ESP32 as Modbus Client & Server.

Has anybody done similar application or is there any library that I can refer to build my code.

I am new to Arduino and have limited knowledge in microcontrollers.

Would be great if anybody helps to kick start. Attached is the pin diagram between the ESP32-wroom-32e and LAN8720A-CP PHY.
