Heck yeah!\u003c\/p\u003e\n\u003cp\u003eWith BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE Shield for Arduino!\u003c\/p\u003e\n\u003cp\u003eThe Bluefruit LE Shield makes it easy to add Bluetooth Low Energy connectivity to your Arduino or compatible.  Solder in the included headers and plug right in. It connects to your Arduino or other microcontroller using the hardware SPI interface (MISO, MOSI, SCK) plus a chip select line (default D8), interrupt line (default D7) and reset (default D4). You can rearrange any and all the pins if you'd like, by cutting the jumpers underneath, and soldering jumper wires to your desired pins.\u003c\/p\u003e\n\u003cp\u003e\u003ca href=\"https:\/\/shop.pimoroni.com\/products\/adafruit-bluefruit-le-spi-friend-bluetooth-low-energy-ble\" target=\"_blank\"\u003eIf you want this in non-shield format, check out the SPI friend.\u003c\/a\u003e\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 profile. In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device.
