Bluefruit LE UART Friend - Bluetooth Low Energy, BLE (Adafruit 2479)

Would you like to add powerful and easy-to-use Bluetooth Low Energy to your robot, art, or other electronics project? Heck yeah! With BLE now included in modern smartphones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE UART Friend!
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! Most people will 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. You can use Adafruit's iOS App or Android App, or write your own to communicate with the UART service.

Why use Adafruit's Module?:

There are plenty of BLE modules out there, with varying quality on the HW design as well as the firmware. So why should you go with this one?
One of the biggest advantages of the Adafruit Bluefruit LE family is that they wrote all of the firmware running on the devices themselves from scratch. They control every line of code that runs on their modules ... and so they aren't at the mercy of any third-party vendors who may or may not be interested in keeping their code up to date or catering to our customer's needs.
Because Adafruit controls everything about the product, they are able to add features that are important to our customers, can solve any issues that do come up without begging any 3rd parties, and can even change Bluetooth SoCs entirely if the need ever arises!
Check out their tutorial for all of the details that you can dream of!
