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).

Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
