# Core Bluetooth Scan for, connect to, and exchange data with Bluetooth Low Energy (BLE) devices. Covers the central role (scanning and connecting to peripherals), the peripheral role (advertising services), background modes, and state restoration. Use `accessorysetupkit` for privacy-preserving accessory discovery and setup; use this skill for direct Core Bluetooth GATT communication. ## Contents - [Setup](#setup) - [Central Role: Scanning](#central-role-scanning) - [Central Role: Connecting](#central-role-connecting) - [Discovering Services and Characteristics](#discovering-services-and-characteristics) - [Reading, Writing, and Notifications](#reading-writing-and-notifications) - [Peripheral Role: Advertising](#peripheral-role-advertising) - [Background BLE](#background-ble) - [State Restoration](#state-restoration) - [Common Mistakes](#common-mistakes) - [Review Checklist](#review-checklist) - [References](#references) ## Setup ### Info.plist Keys | Key | Purpose | |---|---| | `NSBluetoothAlwaysUsageDescription` | Required.
