Newbie here, just getting started. My goal is to create an IoT gateway to AWS MQTT for Modbus over RS-485, using the ESP32. Has anyone gone down this road already and have tips?
It seems like Mongoose OS has support for RS-485 the half duplex and transmit enable control since 2.15.0, so at least that seems doable. But does it work well?
Modbus has timing peculiarities I would rather not re-invent. Has anyone used a Modbus library successfully with Mongoose?
