## What it is
Bluejay is a Swift framework that simplifies building reliable Bluetooth LE apps on iOS. It wraps CoreBluetooth with a callback-based API, FIFO operation queue, background restoration support, and simple serialization protocols.

## Use cases
- connect to a single Bluetooth LE peripheral from an iOS app
- read and write BLE characteristics reliably
- listen for characteristic notifications
- handle automatic reconnection to a BLE device
- perform background BLE tasks and state restoration
- serialize and deserialize BLE data in Swift

## When to choose
- you are building an iOS app that talks to one Bluetooth LE peripheral
- you want a simpler, more predictable API than raw CoreBluetooth
- you need reliable background BLE operations and state restoration

## When to avoid
- you need to manage multiple peripherals simultaneously
- your app targets Android or non-Apple platforms
- you need macOS or Bluetooth Classic support
