How do I set up Blue-Falcon on Windows with JNI?

Blue-Falcon on Windows requires installing Visual Studio 2019+, Windows 10 SDK, and building the native library from the cpp directory. Ensure the bluefalcon-windows.dll is in your Java library path or working directory, as detailed in the Windows requirements section.

Blue-Falcon vs Flutter BLE plugins: which should I use?

Blue-Falcon is best for Kotlin Multiplatform projects seeking a unified API with native performance, while Flutter plugins are better for Flutter-based apps. Choose based on your framework; Blue-Falcon excels in KMP ecosystems for shared BLE logic.

Does Blue-Falcon support BLE 5.0 features like extended advertising?

The README doesn't explicitly mention BLE 5.0 support; it focuses on common BLE operations. For advanced features, check the GitHub issues or source code, as the library may lag behind platform-specific updates.

How to handle Android location permissions with Blue-Falcon?

On Android, you must request ACCESS_COARSE_LOCATION permission before scanning, as shown in the basic usage example where a PermissionException is caught. This aligns with Android's BLE requirements.

Can I use Blue-Falcon with Jetpack Compose on Android?

Yes, the Compose Multiplatform example demonstrates integrating Blue-Falcon with a shared UI for Android and iOS, including device scanning, connection management, and characteristic operations in a reactive way.

What are the limitations of the JavaScript target in Blue-Falcon?

The JavaScript target requires manual copying of the blue-falcon.js file and may have browser compatibility issues; detailed usage is in the JS-Example folder, but it lacks the native integration of other platforms.

BlueFalcon — Kotlin Multiplatform BLE Library

What is BlueFalcon?

Blue-Falcon is a Kotlin Multiplatform library that provides a unified API for Bluetooth Low Energy (BLE) operations across iOS, Android, macOS, Windows, JavaScript, and Raspberry Pi. It solves the problem of platform fragmentation by abstracting the different native BLE APIs into a single, shared codebase, allowing developers to write BLE logic once and deploy it everywhere.

Target Audience

Mobile and embedded developers building applications that need to communicate with BLE devices across multiple platforms, particularly those using Kotlin Multiplatform for shared business logic.

Value Proposition

Developers choose Blue-Falcon to eliminate the duplication of BLE code across platforms, reducing development time and maintenance overhead. Its native compilation ensures performance while its comprehensive API covers the full spectrum of BLE functionality.

Kotlin Multiplatform BLE library for iOS, Android, macos, windows and javascript

Use Cases

Best For

Building cross-platform mobile apps that interact with BLE sensors or peripherals
Creating Kotlin Multiplatform projects with shared BLE device communication logic
Developing applications for Raspberry Pi that require BLE connectivity
Adding BLE capabilities to web applications via its JavaScript target
Prototyping BLE interactions that need to work on both iOS and Android quickly
Unifying BLE codebases across Windows, macOS, and mobile platforms

Not Ideal For

Projects targeting only a single platform like iOS or Android exclusively
Teams unwilling to manage native build tools and dependencies for Windows
Applications requiring cutting-edge, platform-specific BLE features not yet abstracted
Developers not using Kotlin or Kotlin Multiplatform in their stack

Pros & Cons

Pros

True Native Multiplatform

Compiles to native code for each platform (e.g., Objective-C for iOS), acting as 'glue' to unify disparate BLE APIs, ensuring performance while providing a single common interface.

Comprehensive BLE Coverage

Supports full BLE operations including scanning, connecting, read/write, notifications, bonding, MTU changes, and L2CAP channels, as detailed in the extensive API reference.

Reactive Observability

Provides StateFlow streams for discovered peripherals and Bluetooth manager state, enabling easy integration with reactive programming patterns for real-time updates.

Flexible Delegate Pattern

The BlueFalconDelegate interface offers detailed callbacks for all BLE events with default empty implementations, allowing customization without boilerplate code.

Cons

Complex Windows Setup

Requires building a native DLL with Visual Studio and Windows SDK, involving JNI and specific version requirements, which adds significant setup overhead compared to other platforms.

Limited JavaScript Integration

JavaScript usage involves manual copying of compiled files and lacks seamless dependency management, as noted in the install instructions, potentially hindering web development workflows.

Volunteer-Maintained Risks

Acknowledged as maintained by volunteers, which can lead to slower issue resolution and updates, as mentioned in the support section, posing risks for time-sensitive projects.
