2.2 Auracast
Auracast is the broadcast feature of Bluetooth LE Audio: one transmitter sends a single audio stream that any number of Auracast receivers nearby can join.
EV155 supports Auracast receive: it can join a broadcast from a nearby Auracast transmitter and play it through the 3.5 mm line output. Auracast broadcast audio uses the LC3 codec.
Note
Classic Bluetooth and Auracast broadcast are separate operating modes. Follow the prompts on the device screen to choose between them.
