About BLE GAP

GAP controls how BLE devices become visible and connect. Header-level decode helps classify discovery and advertising payload intent before higher-layer interpretation.

GAP (Generic Access Profile) defines device discovery, advertising roles, scanning, and connection initiation behavior.

BLE GAP Header Structure

  • AD Length (when present): size of advertising structure.
  • AD Type: GAP data type identifier.
  • AD Value: type-specific data bytes.

Why Decode BLE GAP Packets

Decode basic BLE GAP payload hints such as AD type and role/discovery metadata.
