When Bluetooth® LE Audio was released, it introduced broadcast audio to Bluetooth technology. This a new feature enables an audio transmitter to broadcast to an unlimited number of nearby Bluetooth audio receivers. Broadcast audio opens significant new opportunities for innovation, including a powerful new capability, Auracast broadcast audio.

Auracast broadcast audio is a set of defined configurations of Bluetooth® broadcast audio which are specified within the Public Broadcast Profile (PBP) specification that enables new, globally interoperable audio experiences for consumers.

If you are developing or thinking about developing an Auracast™ device, you will want to take a look at this series of Auracast developer best practices. Below is the complete suite of Auracast developer best practice guides, now available for download.
