Hi,

Does anyone know anything about this?

Hi @adam_esp,

The previous answer from @fahad_ali_sarwar is correct. The Modbus TCP master/slave functionality implemented from ESP-IDF v4.2.

Welcome,
thanks for the answer, i used version 4.1.
In version 4.2 there are no examples yet, but they are already on the master branch.
I am going to migrate from 4.1 to 4.2. I hope it will be painless

Greetings
