Sample demonstrating how to advertise small amounts of data using the Bluetooth Low Energy API. Also demonstrates how to scan for those Advertisements. (requires 2 devices to see full operation)
This sample demonstrates use of the Bluetooth Low Energy (BLE) Advertisement and Scanning APIs. The functionality is split into two fragments - one for Advertising, one for Scanning.
ScannerFragment activates BLE Scanning for 5 seconds and displays a list of found devices which are advertising using this sample. It shows the device type, Bluetooth address, and when it was last seen. User can refresh to scan again and update the list.
AdvertiserFragment allows the user to toggle BLE Advertising of that device. It broadcasts basic information about the device along with a UUID specific to this app so the ScannerFragment on other devices can filter by it.
Note: A device cannot detect its own BLE advertisements. You will need two devices to see this sample in action.
This sample uses the Gradle build system. To build this project, use the “gradlew build” command or use “Import Project” in Android Studio.
