Is there any samples for Broadcast Assistant Sample using nRF5340 Audio DK

[Eric Dong]

Hello:

We have tried evalution on nRF5340 Audio DK with Audio sample BIS, CIS and WALKIE_TALKIE_DEMO based on NCS v2.2.0

Would you mind let me know is there any "Broadcast Assistant" sample using nRF5340 Audio DK?

My setup should be as below:

One nRF5340 Audio DK working as BIS Gateway (Broadcast Source)

One nRF5340 Audio DK working as BIS Headset (Broadcast Sink)

One nRF5340 Audio DK working as Broadcast Assistant to help Broadcast Sink sync with Broadcast Source

Hi, 

The team is still working on Broadcast Assistant implementation. Hope it could come out soon.

Thanks for your feedback. 

By the way, I found there is an Broadcast Assistant example on Zephyr project: https://docs.zephyrproject.org/latest/connectivity/bluetooth/api/shell/bap_broadcast_assistant.html.

I briefly tried with this:

For BIS Gateway (Broadcast Source), we used the nordic official audio sample with nRF5340 Audio DK 

For Broadcast Assistant, we use the example exists in Zephyr:

• For cpunet: west build -b nrf5340_audio_dk_nrf5340_cpunet samples/bluetooth/hci_rpmsg/
• For cpuapp: west build -b nrf5340_audio_dk_nrf5340_cpuapp tests/bluetooth/shell/ -- -DOVERLAY_CONFIG=audio.conf   

Fro BIS Headset (Broadcast Sink), we use our own board.

The test result as below:

1. Broadcast Assistant can connected and pairedwith BIS headset

2. Broadcast Assistant can do the assistant discover, but no Broadcast Source informarion report.

uart:~$ bap_broadcast_assistant discover

I assume there might be some missed configuration when built the Controller "For cpunet: west build -b nrf5340_audio_dk_nrf5340_cpunet samples/bluetooth/hci_rpmsg/"

Can you help me figure out if anything missed

Hi, 

There are some issues with the Broadcast Assistant, so the team is working on updating the feature.

Are there any updates on this? is the broadcast assistant feature available yet or not?

[Amanda Hsieh]

Hi, 

There's the broadcast assistant feature in Zephyr Host:

https://docs.zephyrproject.org/latest/connectivity/bluetooth/api/shell/bap_broadcast_assistant.html

But we haven't integrated that feature into our nRF5340 audio project.
