BLE-X

BLE-X is a Bluetooth Low Energy (BLE) communication library for Android, designed to provide a structured and reliable way to interact with BLE devices.

Features

• Centralized BluetoothGatt management

• Optimized MTU and PHY handling

• Improved characteristic read/write operations

• Enhanced callback management

• Coroutines support with Kotlin Flow

• Lifecycle-aware connections

• Thread-safe operations

• Exponential backoff reconnection

Quick Start

Initialize the BLE Manager:

val bleManager = BleManager.getInstance(context)

Scan for Devices:

bleManager.scanDevices().collect { device ->
    println("Found: ${device.name}")
}

Connect to a Device:

val connection = bleManager.connect(device)
    .bindToLifecycle(this)

Read/Write Characteristics:

val data = connection.readCharacteristic(serviceUuid, charUuid)
connection.writeCharacteristic(serviceUuid, charUuid, byteArrayOf(0x01))

Requirements

• Android SDK 26+ (Android 8.0 Oreo)

• Kotlin 1.9+
