Bluefruit LE UART Friend or Flora BLE

If you have a stand-alone UART module you have some

flexibility with wiring. However we suggest hardware

UART if possible. You will likely need to use the flow

control CTS pin if you are not using hardware UART.

There's also a MODE pin

You can use this with just about any microcontroller with

at least 3 pins, but best used with a Hardware

Serial/UART capable chip!

Configure the Pins Used

You'll want to check the Bluefruit Config to set up the pins you'll be using for UART or SPI

Each example sketch has a secondary tab with configuration details. You'll want to edit and save the sketch to your

own documents folder once set up.
