Heck yeah!\u003c\/p\u003e\n\u003cp\u003eWith BLE now included in modern smart phones and tablets, its fun to add wireless connectivity.\u003c\/p\u003e\n\u003cp\u003eThe 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).\u003c\/p\u003e\n\u003cp\u003eThis 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.
