2Android BluetoothAdvertisements Sample
3===================================
4
5Sample demonstrating how to advertise small amounts of data using the Bluetooth
6Low Energy API. Also demonstrates how to scan for those Advertisements. (requires
72 devices to see full operation)

9Introduction
10------------
11
12This sample demonstrates use of the Bluetooth Low Energy (BLE) [Advertisement][1] and [Scanning][2] APIs.
13The functionality is split into two fragments - one for Advertising, one for Scanning.
14
15ScannerFragment activates BLE Scanning for 5 seconds and displays a list of found devices which are advertising
16using this sample. It shows the device type, Bluetooth address, and when it was last seen. User can
17refresh to scan again and update the list.
18
19AdvertiserFragment allows the user to toggle BLE Advertising of that device. It broadcasts basic
20information about the device along with a UUID specific to this app so the ScannerFragment on other
21devices can filter by it.
22
23Note: A device cannot detect its own BLE advertisements. You will need two devices to see this
24sample in action.
