Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE) info

Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE) makes it easy to add Bluetooth Low Energy connectivity to any micrcontroller with 4 or 5 GPIO pins. By using SPI, you don't have to worry about baud rates, flow control, or giving up a hardware UART port. Using the BLE module is quite easy. Just connect it to your Arduino or other microcontroller using the common four-pin SPI interface (MISO, MOSI, SCK and CS) plus a 5th GPIO pin for interrupts (to let the Arduino know when data or a response is ready).

This multi-function module of Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE) 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 Adafruit’s iOS or Android App or you can write your own to communicate with the UART service. The links to applications and the Adafruit tutorial can be found in Documents section.

Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE) is capable of 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 a lot more.

Using Adafruit’s Bluefruit iOS App or Android App, you can quickly get your project prototyped by using your iOS or Android phone/tablet as a controller. The apps have a color picker, quaternion/accelerometer/gyro/magnetometer or location (GPS), and an 8-button control game pad.

Adafruit Bluefruit LE SPI Friend - Bluetooth Low Energy (BLE) has lots of other cool features. You can find the links to the tutorials using these features in the Documents section.
