Serial2MQTT interface

Hi,

Is there serial interface in OMG for ESP32? I found some links in codebase to serial interface but they are commented… I need to read values from my energy-meter by using Modbus protocol via RS-485. I buy RS4852Serial board and connect to my ESP32. And now I can read values… But I want to use MQTT-server to read Modbus-registers…

Regards,
Nikolay
