Complete Instructions to Get and Change ESP MAC Address: Īfter uploading the code, press the RST/EN button, and the MAC address should be displayed on the Serial Monitor. Upload the following code to your ESP32 receiver board to get is MAC address.

Each board has a unique MAC address (learn how to Get and Change the ESP32 MAC Address). To send messages via ESP-NOW, you need to know the receiver board’s MAC address. You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price! ESP32 (read Best ESP32 development boards).We’ve experimented with different models of ESP32 boards and all worked well ( ESP32 DOIT board, TTGO T-Journal, ESP32 with OLED board and ESP32-CAM). To follow this tutorial, you need multiple ESP32 boards.

Installing ESP32 Board in Arduino IDE (Windows, Mac OS X, and Linux).

We’ll program the ESP32 boards using Arduino IDE, so before proceeding with this tutorial, make sure you have these boards installed in your Arduino IDE. However, to keep things clear we’ll use the terms “sender” and “receiver” or “master” and “slave”. Note: in the ESP-NOW documentation there isn’t such thing as “sender/master” and “receiver/slave”. You should modify this example to send commands or sensor readings ( exchange sensor readings using ESP-NOW).

As an example, we’ll exchange random values between the boards.

The ESP32 receiver board receives the messages from all senders and identifies which board sent the message.

The sender board receives an acknowledge message indicating if the message was successfully delivered or not.

You should be able to add more boards to your setup We’ve tested this example with 5 ESP32 sender boards and it worked fine.

Multiple ESP32 boards act as senders/masters.

One ESP32 board acts as a receiver/slave.
