## What it is
Noble is a Node.js library for acting as a Bluetooth Low Energy (BLE) central device, enabling scanning, connecting to, and interacting with BLE peripherals. It supports macOS, Linux, FreeBSD, and Windows.

## Use cases
- scan for nearby BLE devices from Node.js
- read and write BLE peripheral characteristics
- connect to heart rate monitors or sensors over Bluetooth LE
- build a BLE gateway or bridge application
- discover BLE services and notifications in JavaScript

## When to choose
- you need BLE central-role functionality in a Node.js app on a supported OS
- you want a mature, MIT-licensed library with broad OS support

## When to avoid
- you need to implement a BLE peripheral (use bleno instead)
- you need active development or support for newer Node versions, as the latest release is from 2022
- you are on an unsupported operating system

## Facets
- artifact type: library
- maturity: maintenance
- function: sdk, developer-tools
- domain: developer-tools, iot, hardware, cross-platform
- platform: windows, bsd, cross-platform
- tags: bluetooth-low-energy, ble-central, iot-connectivity, hardware-access, nodejs, macos, linux
