Adafruit Bluefruit LE - UART Breakout

The Bluefruit LE UART breakout makes it easy to add Bluetooth Low Energy connectivity to anything with a hardware or software serial port. Adafruit have a 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. You can use our iOS App or Android App, or write your own to communicate with the UART service.

The board is capable of much more than just sending strings over the air. Thanks to an easy to learn AT command set, you have full control over how the device behaves, including the ability to define and manipulate your own GATT Services and Characteristics, or change the way that the device advertises itself for other Bluetooth Low Energy devices to see. You can also use the AT commands to query the die temperature, check the battery voltage, and more, check the connection RSSI or MAC address, and tons more.

Using Adafruits' Bluefruit iOS App or Android App, you can quickly get your project prototyped by using your iOS or Android phone/tablet as a controller.
