|
* by Broadcast Audio Scan Service (BASS) residing on a Scan Delegator.
|

|
*

* <p>For example, the Scan Delegator on an LE Audio Broadcast Sink can use the information

* <p>BroadcastAssistant has a BASS client which facilitates scanning and discovery of Broadcast

|
* sources, this information needs to be communicated to the BASS Server residing within the Scan

* Transfer (PAST) procedure. This procedure uses information contained within an instance of this
