## What it is
A React Native library for Bluetooth Low Energy (BLE) communication on iOS and Android. It supports scanning, connecting, service/characteristic discovery, reading/writing, notifications, RSSI, MTU negotiation, and iOS background mode.

## Use cases
- scan for BLE devices in a React Native app
- connect to a BLE peripheral and read/write characteristics
- subscribe to characteristic notifications from a heart-rate sensor
- negotiate MTU with a BLE device on Android
- run BLE scanning in the background on iOS
- read RSSI from nearby Bluetooth devices

## When to choose
- you need central-mode BLE in a React Native or Expo app
- you want a mature, widely used BLE library with active maintenance
- you need iOS background BLE support

## When to avoid
- you need Bluetooth Classic or beacon support
- you need peripheral mode to communicate between phones
- you need bonding support
- you are not building a React Native app

## Facets
- artifact type: library
- maturity: active
- function: sdk, iot
- domain: mobile-development, iot, cross-platform
- platform: -
- tags: react-native, bluetooth-low-energy, ble, expo, peripherals, android, ios, mobile, javascript
