## What it is
FastBle is an Android Bluetooth Low Energy development framework that simplifies BLE operations like scanning, filtering, connecting, reading, writing, and notifications. It supports multi-device connections, auto-reconnection, RSSI reading, and MTU configuration through a fluent Java API.

## Use cases
- scan and filter BLE devices by name, MAC, or UUID on Android
- connect to multiple BLE peripherals simultaneously
- read and write BLE characteristics with notifications and indications
- implement auto-reconnection for BLE devices with retry logic
- read signal strength (RSSI) and set MTU for BLE connections
- build an Android app that talks to BLE sensors or wearables

## When to choose
- you are building an Android app in Java that communicates with BLE devices
- you need multi-device BLE connections with simple callback-based APIs
- you want built-in reconnection, timeouts, and scan filtering without writing raw BluetoothGatt code

## When to avoid
- you are developing for iOS, desktop, or non-Android platforms
- you need Kotlin-first or coroutine/Flow-based BLE APIs
- your project requires BLE features outside the Android BLE stack, such as Bluetooth Classic

## Facets
- artifact type: library
- maturity: active
- function: sdk, developer-tools
- domain: android-tools, developer-tools, iot
