# Sparkfun Pro RF - Basic LongFi Example

This example demonstrates sending a simple data packet using a Sparkfun Pro RF development board. Visit our quickstart guide [here](https://developer.helium.com/devices/arduino-quickstart/sparkfun-pro-rf).

## Required Arduino Libraries

From the Arduino IDE, open the Library Manager (Sketch->Include Library->Manage Libraries). In the search box, type the library name below and install version `1.5.0+arduino-2`.

[IBM LMIC framework](https://github.com/matthijskooijman/arduino-lmic)  

### Required Configuration
This library requires that a config file be setup properly. After you have installed the `IBM LMIC framework` library, navigate to it's directory on your operating system found below. Next, replace the `config.h` file in this directory with this [config.h](https://github.com/helium/longfi-arduino/blob/master/Sparkfun-Pro-RF/longfi-us915/config.h) file.
