Description
Limitations
Maturity level
Broadcasting audio using Broadcast Isochronous Stream (BIS) and Broadcast Isochronous Group (BIG).
Play and pause emulated by disabling and enabling stream, respectively.
The following limitations apply:

Audio input: USB or I2S (Line in or using Pulse Density Modulation).
Configuration: 16 bit, several bit rates ranging from 32 kbps to 124 kbps.
Experimental
Receiving broadcast audio using BIS and BIG.
Synchronizes and unsynchronizes with the stream.
The following limitations apply:
One BIG, one of the two BIS streams (selectable).
Audio output: I2S/Analog headset output.
Configuration: 16 bit, several bit rates ranging from 32 kbps to 124 kbps.
Experimental
One Connected Isochronous Group (CIG) with two Connected Isochronous Streams (CIS).
Transmitting unidirectional or transceiving bidirectional audio using CIG and CIS.
The following limitations apply:
One CIG with two CIS.
Audio input: USB or I2S (Line in or using Pulse Density Modulation).
Audio output: USB or I2S/Analog headset output.
Configuration: 16 bit, several bit rates ranging from 32 kbps to 124 kbps.
Experimental
One CIG with one CIS stream.
Receiving unidirectional or transceiving bidirectional audio using CIG and CIS.
Coordinated Set Identification Service (CSIS) is implemented on the server side.
The following limitations apply:
