The Bluefruit LE SPI Friend makes it easy to add Bluetooth Low Energy connectivity to anything with 4 or 5 GPIO pins. With SPI, you don't have to worry about baud rates, flow control, or giving up a hardware UART port. Connect 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 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 Adafruits 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. Really, way too long to list here!

Download Adafruits free Android/iOS app and you're ready to rock!

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. The apps have a color picker, quaternion/accelerometer/gyro/magnetometer or location (GPS), and an 8-button control game pad.

You can do a lot more too, see the Tutorial below in the Documents section!

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 Adafruit 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 we 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.

Specification:

  • ARM Cortex M0 core running at 16MHz
  • 256KB flash memory
  • 32KB SRAM
  • Transport: SPI at up to 4MHz clock speed
  • 5V-safe inputs (Arduino Uno friendly, etc.)
  • On-board 3.3V voltage regulation
  • Bootloader with support for safe OTA firmware updates
  • Easy AT command set tunneled over SPI protocol to get up and running quickly
  • Dimensionen: 23mm x 26mm x 5mm / 0.9" x 1" x 0.2"
  • Weight: 3g
