Combine CIS input stream to BIS broadcasting with Audio support

[gt2ishan]

Im currently working on a project which should receive audio through CIS and retransmit it over BIS. Im using nrf5340_audio_dk for this.
Ive tried using https://docs.nordicsemi.com/bundle/ncs-3.0.2/page/nrf/samples/bluetooth/iso_combined_bis_and_cis/README.html but this doesnt support audio.

Is there a sample project already that has this behaviours? Please help me.

Thanks

Hi Ishan,

You do not have to use raw ISO; you can use the Basic Audio Profile (BAP) for both CIS and BIS. The Nordic Softdevice Controller and nRF Connect SDK support BAP, and the tested configurations for the SoftDevice Controller include both CIS and BIS in line with the BAP specification. Parellel use of one CIS and one BISis also tested. See here: https://docs.nordicsemi.com/bundle/ncs-latest/page/nrfxlib/softdevice_controller/doc/isochronous_channels.html#configurations_for_parallel_use_of_cis_and_bis

Hi,

Im able to run CIS and BIS parallel. Question is can we use BAP for both CIS and BIS to run at the same time?
