To install the ESP32 board in your Arduino IDE, follow these next instructions:ġ) Open the preferences window from the Arduino IDE. Never power on the board without connecting the antenna first as you may damage the radio chip on board.Go to the end of this part to learn how to remove the espressif folder by following Part 1 Note#1. If you’ve already installed the ESP32 add-on using the old method, you should remove the espressif folder first.If this is your first time installing the ESP32 on the Arduino IDE, simply follow the installation procedure described below.This add-on for the Arduino IDE allows you to program the ESP32 using the Arduino IDE and its programming language. The ESP32 is currently being integrated with the Arduino IDE just like it was done for the ESP8266. If you don’t, uninstall it and install it again.

Important: before starting this installation procedure, make sure you have the latest version of the Arduino IDE installed in your computer. PART 1 Setting up the Arduino IDE for ESP32

This project will also work using other ESP32 development board’s with WiFi, LoRa and OLED but pin_mapping will be different and will require good knowledge of how to follow schematics and pin_out diagrams of the selected board. A working LoRa Gateway connected to The Things Network will also be needed. Some soldering skills are also required to attached the header pins to the ESP32 board. This project assumes some knowledge of the Arduino IDE, LoRaWAN and of ESP32 in general. An TTN account is also needed to register the Mote and application. You will also need to purchase an antenna and pig tail connector (U.FL to SMA). The code and libraries used in the project can be found on GitHub. In this project we will be using the ESP32 Heltec WiFi LoRa OLED board from Banggood to build a LoRaWAN Mote (end node) to send data from an DHT22 sensor to The Things Network(TTN) and display the sensor values.
