Hot to read and write data to a bluetooth low energy device.

This section describes how central (iOS app) can scan available BLE peripherals and connect with one we are interested in.

This documentation is meant as an enhancement over the original documentation and it will focus on the latest Bluetooth LE API introduced in Android 5.0 (API 21). Both Central and Peripheral roles will be covered as well as how to start scanning and advertising operations.

In Xamarin.Android the BluetoothSocket.InputStream and BluetoothSocket.OutputStream properties are by design automatically converted to System.IO.Stream. In case of so called interactive communication protocol, when server responds only when client talks to it, System.IO.Stream is not good because it has no method or property to get the number of available response bytes before reading the response.
