Generic Access Profile (GAP) Overview

The Generic Access Profile (GAP) modes and procedures form the cornerstone of the 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 as most the BLE implementations provide GAP APIs for applications wishing to use this functionality.
