Android BluetoothKit
Android-BluetoothKit is a communication library for Android designed to manage Bluetooth Low Energy connections, GATT services, and characteristic data exchange. It provides a GATT client for reading and writing data, a device scanner for discovering hardware, and a connection manager to track device states.
The library features a pointer-based beacon parser that extracts custom data from device broadcasts without requiring a full connection. It also implements a serialized request queue to process Bluetooth operations sequentially, preventing race conditions and managing transmission timeouts.
The project covers broad capability areas including device connectivity, data exchange, and hardware management. This includes the ability to control Bluetooth radio states, manage native interface handles to prevent memory leaks, and execute high-speed data writes to remote peripherals.
