Setting up a new ESP32 Node

This page describes how to set up a new ESP32 node for the peer-to-peer sensor network lab setup.

First, ensure that you have the Micropython firmware installed on the ESP32.

Adding the required files

1. Connect the ESP32 to your computer via USB.
2. Copy the required files to the ESP32. You can use the mpremote command or for example the Arduino Labs for Micropython Software.
3. The required files are:
   • main.py: The main script that runs on the ESP32. Choose one from the udp or espnow directory.
   • boot.py: Script to read data from the dust sensor.
   • lib/: Library required for the dust sensor.
   • util/: Additional utility functions.
4. Edit the config.py file to set a unique hostname and credentials for the network connection. Copy this file to the root directory of the ESP32.
