This tutorial will guide you Communication between multiple ESP32 To communicate multiple ESP32 devices using the RS485 protocol, you need to choose an RS485 transceiver. Learn how to send/receive data via RS485 using ESP32, how to program ESP32 step by step. Contribute to espressif/arduino-esp32 development by creating an account on GitHub. Below is the wiring diagram for my setup: In this tutorial, we will discuss how we can interface ESP32 (as master) to any RS485 (Modbus RTU) based sensor (as slave) using Arduino IDE. In addition, the output of your sending ESP32 should go to the DI pin of the MAX485 - NOT the RO pin. Similar connection for ESP32, but we are going to use Serial1 The ModbusRTU_ESP32 Library enables any ESP32 to function as a Modbus RTU slave device using the RS-485 protocol. - WillyBilly06/ESP32-A2DP-SINK-WITH-CODECS-UPDATED An example on how to send dmx over a max485 with an ESP8622 and ESP32.
