ESP32 LoRa 1-CH Gateway, LoRaWAN, and the Things Network

Arduino IDE Setup
To set up the gateway software you'll need to install the ESP32 Arduino core as well as the library dependencies of the ESP32 LoRa Gateway sketch.
Arduino Board Setup
The example code and libraries for this board are all written for the Arduino IDE. If you haven't already done so, you'll need to install the Arduino core for ESP32. The ESP32 Arduino core must be installed manually. You can find the core files on espressif's GitHub: https://github.com/espressif/arduino-esp32. Follow the Installation Instructions to add the core to your Arduino IDE.
Adding a Custom Board
Although it's possible to upload code to the board using the standard board definitions, we recommend customizing the core to add support for the SparkX ESP32 LoRa Gateway.
To add the custom board, begin by downloading the board's variant file here below.
Then unzip the contents into ...{Arduino Sketchbook}/hardware/espressif/esp32/variants.
Next, copy the text below and add it to the bottom of ...{Arduino Sketchbook}/hardware/espressif/esp32/boards.txt:

This custom board file specifies the SPI and built-in LED pins. Without it, you'll need to re-define them in your sketch.
Once the custom board has been added to the ESP32 core, open Arduino and select "SparkX ESP32 LoRa Gateway" under the Tools > Board > ESP32 Arduino menu.
