## Health v2 (maintenance only)
Score: 95/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 100, release rhythm 85, longevity 100
- inputs: {"age_days": 2058, "days_push": 0, "days_rel": 23, "gap_med": 35, "n_releases_24m": 12}
- flags: no_license
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
SimpleBLE is a cross-platform Bluetooth Low Energy library offering a unified C++ API with bindings for C, Python, Java, Rust, Kotlin, and Unreal Engine. It wraps native OS stacks (WinRT, CoreBluetooth, BlueZ, Android Bluetooth) and is dual-licensed under BUSL-1.1 with commercial licensing options.

## Use cases
- scan for BLE devices from a cross-platform C++ app
- connect to a heart rate monitor from Python
- build a BLE peripheral on Windows and macOS with one codebase
- add Bluetooth LE support to an Android app from Java or Kotlin
- use Bluetooth in an Unreal Engine game or simulation
- prototype BLE automation scripts in Python
- read sensor data from an IoT device over BLE

## When to choose
- you need one BLE API across Windows, macOS, Linux, iOS, and Android
- you want vendor-supported, production-grade Bluetooth with commercial licensing
- you need bindings in C++, C, Python, Java, Rust, or Unreal Engine
- you need both central and peripheral BLE roles

## When to avoid
- you need a permissively licensed library for commercial use without paying or waiting for GPL conversion
- you only target Linux and prefer a lightweight BlueZ wrapper
- you need Bluetooth Classic (BR/EDR) rather than BLE
- you need a mature OSI-approved open-source license for redistribution

## Facets
