Implement BLE central and peripheral roles by orchestrating scanning, connecting, advertising, and hosting GATT services through the Core Bluetooth framework to achieve stable peer-to-peer device connectivity.

Core Bluetooth background execution fails without proper state restoration and background mode configuration. You must handle manager states and implement state restoration patterns to ensure robust background connectivity.

Discover GATT services and interact with characteristics by implementing Core Bluetooth central role scanning for specific service UUIDs and handling characteristic read, write, and notify operations.

Handle Core Bluetooth state restoration by implementing state-dependent lifecycle patterns that preserve manager states, ensuring your BLE app recovers reliably from background termination and power-aware interruptions.

Manage L2CAP channels using Core Bluetooth to handle complex data transfer scenarios, ensuring efficient peer-to-peer messaging links while adhering to Apple's strict power-aware guidelines and security-focused pairing protocols.

Handle the poweredOn state correctly before scanning for BLE devices. Checking Core Bluetooth manager states is a critical lifecycle requirement to avoid improper state management and memory leaks.
