A Flutter library for reactive Bluetooth Low Energy (BLE) operations supporting multiple device connections.
Flutter Reactive BLE is a Flutter library that handles Bluetooth Low Energy (BLE) operations for mobile applications. It provides a reactive API to discover, connect to, and communicate with multiple BLE devices across Android and iOS platforms. The library solves the complexity of managing BLE interactions, such as device discovery, characteristic read/write, and connection state management, in a cross-platform manner.
Flutter developers building mobile applications that need to interact with BLE devices, such as IoT gadgets, sensors, wearables, or smart home equipment. It's suitable for projects requiring reliable multi-device BLE communication on both Android and iOS.
Developers choose this library for its reactive design, which simplifies asynchronous BLE event handling via streams. It offers robust multi-device connection management, platform-specific optimizations (e.g., Android GATT cache clearing), and a unified API that reduces the overhead of dealing with native BLE stack differences.

Uses streams for BLE events like device discovery and status updates, enabling clean asynchronous code as shown in the scanForDevices and statusStream examples.
Supports simultaneous connections to multiple BLE devices with APIs for establishing and maintaining connections, crucial for IoT applications handling several sensors.
Provides a unified API for Android and iOS, handling platform-specific permissions and optimizations like Android GATT cache clearing and iOS BLE status monitoring.
Includes operations like MTU negotiation, connection priority adjustment, and write without response for high-throughput scenarios, detailed in the usage section.
Requires workarounds for issues like the BLE undeliverable exception, necessitating additional Kotlin code and dependency on RxAndroidBle, as admitted in the FAQ.
iOS has fixed MTU size that cannot be negotiated, and some advanced operations like connection priority are Android-only, limiting feature parity across platforms.
Demands careful configuration of platform-specific permissions and ProGuard rules, with verbose steps for Android and iOS, increasing initial development time.
