LE Audio supports the following topologies

  • Multiple pairs of left and right (multiple earbuds)

Broadcast

  • Connectionless broadcast with no acknowledgements
  • Multiple channels
    • Stereo left and right
    • different language channels

Unicast allows for native stereo earbud type applications, built directly into BT5.2.
Broadcast allows for many new use cases such as public announcements in airports/railway stations. A cinema showing a film but with multiple language channels.
