How to scan for BLE devices with RxBluetoothKit?

Use the `scanForPeripherals` method from the manager, which returns an observable stream of peripherals. Specify service UUIDs to filter results, and refer to the wiki for detailed examples and error handling.

RxBluetoothKit vs CoreBluetooth: which should I use?

RxBluetoothKit simplifies code with reactive streams and reduces callback hell, but adds RxSwift overhead. CoreBluetooth is lower-level and more verbose, better for minimal dependencies or simple tasks.

Does RxBluetoothKit support background Bluetooth on iOS?

Yes, it integrates with CoreBluetooth's background modes, but you must configure your app's Info.plist with Bluetooth usage descriptions, as mentioned in the changelog for version 6.0.0 updates.

How to handle connection errors in RxBluetoothKit?

Leverage RxSwift's error handling operators like `catchError` or `retry` on the observables from library methods, ensuring robust fault tolerance for scenarios like device disconnections or timeouts.

Can I use RxBluetoothKit with Swift Combine instead of RxSwift?

No, it's built specifically on RxSwift and doesn't natively support Combine. For Combine, you'd need adapters or consider alternative libraries, as this isn't addressed in the documentation.

What are the minimum iOS and Swift version requirements?

Requires iOS 9.0+ and Swift versions aligned with library updates (e.g., Swift 5.0 for version 5.2), as detailed in the requirements section, with recent versions supporting Xcode 11.4+.

iOS & OSX Bluetooth library for RxSwift — Reactive Bluetooth for Apple

What is iOS & OSX Bluetooth library for RxSwift?

RxBluetoothKit is an open-source library for iOS and macOS that provides a reactive wrapper around Apple's CoreBluetooth framework using RxSwift. It simplifies Bluetooth Low Energy (BLE) interactions by exposing Bluetooth operations as observable streams, making it easier to handle asynchronous events like scanning, connecting, and data transfer in a declarative way.

Target Audience

iOS and macOS developers building applications that communicate with BLE devices, such as IoT gadgets, health sensors, or smart accessories, who prefer reactive programming patterns.

Value Proposition

Developers choose RxBluetoothKit because it replaces CoreBluetooth's complex delegate-based API with a clean, composable RxSwift interface, reducing boilerplate and improving code readability and maintainability for BLE workflows.

iOS & OSX Bluetooth library for RxSwift

Use Cases

Best For

Building iOS/macOS apps that connect to BLE peripherals like heart rate monitors
Developing reactive IoT applications that interact with smart devices
Simplifying complex BLE workflows with declarative RxSwift code
Creating cross-platform Bluetooth apps for Apple's ecosystem (iOS, macOS, watchOS, tvOS)
Handling multiple BLE operations concurrently with observable streams
Reducing callback hell and state management in Bluetooth-enabled apps

Not Ideal For

Projects not using RxSwift or unwilling to adopt reactive programming patterns
Cross-platform applications requiring Bluetooth support on Android, Windows, or Linux
Simple BLE tasks where the overhead of RxSwift outweighs the benefits of direct CoreBluetooth usage

Pros & Cons

Pros

Reactive Stream Integration

Transforms CoreBluetooth's callback-heavy API into RxSwift observables, enabling declarative and composable code as shown in the sneak peek snippet, reducing boilerplate and improving readability.

Comprehensive BLE Coverage

Supports both Central and Peripheral modes with features like scanning, connecting, reading/writing, and L2CAP channels, detailed in the wiki links for almost all functionalities.

Cross-Apple Platform Consistency

Provides a unified API across iOS, macOS, watchOS, and tvOS, as listed in Key Features, minimizing platform-specific code for Apple ecosystem developers.

Active Maintenance and Community

Regular updates like version 6.0.0 with migration guides, plus support via Gitter, StackOverflow, and a sample app, indicating robust ongoing development and user assistance.

Cons

Heavy RxSwift Dependency

Requires RxSwift, which adds significant library size and complexity, forcing developers to learn reactive programming if not already familiar, potentially overcomplicating simple projects.

Apple-Only Platform Support

Limited to Apple platforms (iOS, macOS, watchOS, tvOS), as specified in requirements, making it unsuitable for applications targeting Android, Windows, or other operating systems.

Steep Learning Curve

The reactive approach, while powerful, can be challenging for developers accustomed to imperative or delegate-based patterns, as implied by the philosophy of transforming CoreBluetooth.
