1 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. 25 26 [1]:https://developer.android.com/reference/android/bluetooth/le/BluetoothLeAdvertiser.html 27 [2]:https://developer.android.com/reference/android/bluetooth/le/BluetoothLeScanner.html 28 29 Pre-requisites 30 -------------- 31 32 - Android SDK 25 33 - Android Build Tools v25.0.3 34 - Android Support Repository 35 36 Screenshots 37 ------------- 38 39 <img src="screenshots/1-main.png" height="400" alt="Screenshot"/> 40 41 Getting Started 42 --------------- 43 44 This sample uses the Gradle build system.
