BLE Basics is a very basic iOS application to discover and explore Bluetooth Low Energy (BLE) Peripherals, Services, and Characteristics. Particularly, it detects and displays some of the newer DESCRIPTOR variants that provide a Units Code, Exponent, User Description, and Value Numeric Type per Bluetooth 4.0 and 4.1
Requires Xcode 7.1.
Here’s a lengthy but really in-depth tutorial walkthrough for the application and its features:

Adafruit Bluefruit LE SPI Friend – Bluetooth Low Energy (BLE): 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).
