Android BluetoothLeGatt Sample

This sample demonstrates how to use the Bluetooth LE Generic Attribute Profile (GATT)
to transmit arbitrary data between devices.

Introduction

This sample shows a list of available Bluetooth LE devices and provides
an interface to connect, display data and display GATT services and
characteristics supported by the devices.

It creates a Service for managing connection and data communication with a GATT server
hosted on a given Bluetooth LE device.

The Activities communicate with the Service, which in turn interacts with the Bluetooth LE API.

Pre-requisites
