The Generic Access Profile (GAP) modes and procedures form the cornerstone for Bluetooth® Low Energy (BLE) 'control-plane' operations:
- Discover and connect with peers
- Broadcast data
- Establish secure connections
GAP defines these and other fundamental operations in a standard, universally understood manner. It's important to understand GAP, since most BLE implementations provide GAP APIs for applications wishing to use this functionality.
