Introducing the Adafruit Bluefruit LE SPI Friend — a powerful and easy-to-use Bluetooth Low Energy (BLE) module designed to bring wireless connectivity to your robot, art, or electronics project! With BLE support now standard on most smartphones and tablets, it’s never been easier to add wireless features to your creations.
This compact module connects to your Arduino or microcontroller using a simple four-pin SPI interface (MISO, MOSI, SCK, and CS), plus a fifth GPIO pin for interrupts, allowing you to send and receive data efficiently without the hassle of baud rates or flow control. Whether you're building a Bluetooth-enabled robot or adding wireless functionality to your project, the Bluefruit LE SPI Friend makes it a breeze.
Key Features:
-
SPI Communication: Uses a 4-pin SPI interface for easy and fast communication with your microcontroller, freeing up UART ports for other uses.
-
Nordic UART RX/TX: This connection profile makes the Bluefruit act as a data pipe, enabling seamless communication between your iOS or Android device and your project.
-
Customizable AT Command Set: Gain full control over the device’s behavior with AT commands, allowing you to define your own GATT services and characteristics, adjust advertisement settings, and more.
-
Monitor Status: Use AT commands to check the device's temperature, battery voltage, connection RSSI, MAC address, and much more.
More than Just Data Transfer:
-
HID Keyboard: The module can act as a Bluetooth Low Energy keyboard for devices that support BLE HID.
-
Heart Rate Monitor: Transform the Bluefruit into a BLE heart rate monitor (requires additional pulse-detection circuitry).
-
UriBeacon: Turn it into a Bluetooth LE beacon that transmits a URL to nearby devices with the UriBeacon app installed.
-
Over-the-Air Updates: Built-in bootloading feature allows you to update the firmware using an Android or iOS device to keep your module up-to-date.
Easy Prototyping with Apps:
-
Bluefruit iOS & Android Apps: Our free apps make prototyping quick and simple. Use your smartphone or tablet as a controller for your project, with features like a color picker, accelerometer/gyro/magnetometer/quat, location (GPS), and an 8-button gamepad control.
Why Choose Adafruit's Bluefruit LE SPI Friend?
