## What it is
RxAndroidBle is an Android Bluetooth Low Energy library that wraps Android's BLE APIs into RxJava reactive observables. It handles asynchronous operations (read, write, notifications), threading management, and connection/operation error handling.

## Use cases
- scan for BLE devices on Android
- connect to a Bluetooth LE peripheral and read characteristics
- subscribe to BLE notifications from a sensor
- write data to a BLE device characteristic
- handle Android BLE permission requirements for scanning and connecting
- manage BLE connection state and errors reactively

## When to choose
- building an Android app that communicates with BLE devices like wearables, sensors, or beacons
- you want a reactive RxJava API over Android's callback-heavy BLE stack
- you need reliable threading and error handling for BLE operations

## When to avoid
- developing for platforms other than Android
- you prefer coroutines or callback-based APIs over RxJava
- you need Bluetooth Classic (not BLE) support

## Facets
- artifact type: library
- maturity: active
- function: sdk, developer-tools
- domain: mobile-development, developer-tools, cross-platform
- platform: jvm
- tags: bluetooth-low-energy, ble, rxjava, reactive, android-library, iot, android, mobile
