(Basic Audio Profile)
A key, low-level Bluetooth profile that enables LE Audio, the newer standard for all kinds of audio over Bluetooth wireless connections.
See: LE Audio
A phone must support both Bluetooth 5.2 (or newer) and BAP to use LE Audio, including new features such as broadcast (one-to-many) audio services.
Several other core, low-level profiles are generally also required for LE Audio, such as CAP (Common Audio Profile), MCP (Media Control Profile), CCP (Call Control Profile), and VCP (Volume Control Profile).
In addition, one or more "Use Case" profiles are required to actually use LE Audio. These higher-level profiles include TMAP (Telephony and Media Audio Profile), PBP (Public Broadcast Profile), and HAP (Hearing Access Profile, for Hearing Aid ecosystem).
