Modbus RTU and TCP

Postby rtborg » Sat Apr 30, 2022 6:46 am

I'm looking for recommendation for Modbus TCP master library for ESP32. I can't use the embedded API, as I am already using Modbus RTU.

Thanks

Thanks for the link, haven't tried that. I am using espidf, not Arduino, it would probably not be a solution.
