Overview

The Bluefruit LE UART Friend makes it easy to add Bluetooth Low Energy connectivity to anything with a hardware or software serial port. We even have nice hardware flow control so you won't have to think about losing data. Connect to your Arduino or other microcontroller or even just a standard FTDI cable for debugging and testing.

This multi-function module can do quite a lot! For most people, they'll be very happy to use the standard Nordic UART RX/TX connection profile. In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device.
