After wiring the Bluefruit LE module to Circuit Playground you'll need to do a small bit of software setup to run the examples.
First if you're new to Circuit Playground be sure to follow its guide to setup Arduino for programming the board. Make sure you can load some of the basic examples like blinking a LED on the board before continuing further. Also don't forget to install the Circuit Playground library in Arduino as the guide mentions.
Next follow the Bluefruit LE module guide to install the necessary Arduino libraries for using the module. In particular you need to install this library (use the library manager in Arduino to search for and easily install it):
That should be all the setup necessary to program Circuit Playground with sketches that use a Bluefruit LE module! The next pages explain example sketches to control Circuit Playground with the Bluefruit LE module.
