      2 Android BluetoothAdvertisements Sample
      3 ===================================
      4 
      5 Sample demonstrating how to advertise small amounts of data using the Bluetooth
      6 Low Energy API. Also demonstrates how to scan for those Advertisements. (requires
      7 2 devices to see full operation)
      8 
      9 Introduction
     10 ------------
     11 
     12 This sample demonstrates use of the Bluetooth Low Energy (BLE) [Advertisement][1] and [Scanning][2] APIs.
     13 The functionality is split into two fragments - one for Advertising, one for Scanning.
     14 
     15 ScannerFragment activates BLE Scanning for 5 seconds and displays a list of found devices which are advertising
     16 using this sample. It shows the device type, Bluetooth address, and when it was last seen. User can
     17 refresh to scan again and update the list.
     18 
     19 AdvertiserFragment allows the user to toggle BLE Advertising of that device. It broadcasts basic
     20 information about the device along with a UUID specific to this app so the ScannerFragment on other
     21 devices can filter by it.
     22 
     23 Note: A device cannot detect its own BLE advertisements. You will need two devices to see this
     24 sample in action.
