This sample demonstrates how to use the Bluetooth LE Generic Attribute Profile (GATT) to transmit arbitrary data between devices.
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.
This sample uses the Gradle build system. To build this project, use the “gradlew build” command or use “Import Project” in Android Studio.
