8Introduction
9------------
10
11This sample shows a list of available Bluetooth LE devices and provides
12an interface to connect, display data and display GATT services and
13characteristics supported by the devices.
14
15It creates a [Service][1] for managing connection and data communication with a GATT server
16hosted on a given Bluetooth LE device.
17
18The Activities communicate with the Service, which in turn interacts with the [Bluetooth LE API][2].
