This card allows wireless data transmission via Bluetooth Low Energy. It communicates via SPI interface (MISO, MOSI, SCK and CS pins) plus a GPIO pin for interrupts. Thanks to a firmware developed and updated by Adafruit, it is possible to issue commands to the BLE module via AT Commands, an aspect that allows total control over the behavior of the device and to obtain information such as battery voltage, RSSI, MAC address, etc. . The heart of the BLE module is a Nordic nrf51822. We also have a version that communicates via UART.

Description

Would you like to add Bluetooth Low Energy to your robot, art or other electronics project? Heck yeah! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. Adafruit Bluefruit THE SPI Friend!

The Bluefruit 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 to UART port hardware. Connect to your Arduino or other microcontrollers using the common four-pin SPI interface (MISO, MOSI, SCK and CS) plus to 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 will be happy to use the Nordic standard UART RX / TX connection profile. In this profile, the Bluefruit acts as a data pipe, which 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.

If you like Serial communication more than SPI, we also have a version that can talk UART

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, GATT Services and Characteristics, or change the way the device advertises itself for other Bluetooth Low Energy devices to see. Check the battery voltage, and check the connection RSSI or MAC address, and tons more. Really, way too long to list here!

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

Using our Bluefruit IOS App or Android App, you can quickly get your project prototyped by using your iOS or Android phone / tablet as a controller. We 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!

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 Bluefruit Adafruit LE family is that we wrote all the firmware running on our devices from scratch. We control every line of code that runs on our modules ... and we are not at the mercy of any third party vendors who may or may not be interested in their code.

Because we control everything about the product, we add features that are important to our customers, you can solve any issues that come up without begging any XNUM Xrd parties, and we can even change Bluetooth SoCs entirely if the need ever arises!

Check out our tutorial for the details that you can dream of!
