nRF3530 Audio DK [GATEWAY][UNICAST_CLIENT] -- Unable to stream audio to earbud from the DK .

[Jeevan Kumar]

Hi Team, 

I have 1 nRF5340 Audio DK. With the steps mentioned in below links, I configured Json file to Gateway and I'm able to achieve it. (https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.4.2/nrf/applications/nrf5340_audio/README.html#building-and-programming-using-script)

Setup Details :
Gateway - nRF5340 Audio DK
Headset - Sony WF-1000XM5.
SDK Version : nRF Connect SDK v2.6.0
Application: nrf5340_audio.

Procedure: 
Step 1: Building is done with nrf5340_audio with below configurations. 
Step 2: Flashed board with application and then performed reset.
Step 3: Connected to earbuds.
Step 4: Streaming is stared from the laptop.
<NO AUDIO IS OBSERVED FROM THE EARBUDS>

Also, I observed below warning messages :
1.  <wrn> unicast_client: No more space. Increase CODEC_CAPAB_COUNT_MAX is observed after connecting with Earbuds. (nrf5340_audio/src/bluetooth/unicast/unicast_client.c - line 671)
2.  <wrn> unicast_client: More than one sink endpoint found, idx 0 is used by default is observed after successful connection. (nrf5340_audio/src/bluetooth/unicast/unicast_client.c - line 689)

In prj.conf, added following configurations. (These configuration are referred from previously answered questions)

CONFIG_AUDIO_DEV=2
CONFIG_TRANSPORT_CIS=y
CONFIG_BT_OBSERVER=y
CONFIG_BT_DEVICE_NAME="WF-1000XM5"
CONFIG_BT_VCP_VOL_REND=y
CONFIG_BT_CSIP_SET_MEMBER=y
CONFIG_BT_MCC=y
CONFIG_TRANSPORT_BIS=n
CONFIG_AUDIO_SOURCE_USB=n
CONFIG_AUDIO_SOURCE_I2S=y
CONFIG_BT_LOG_SNIFFER_INFO=y
CONFIG_STREAM_BIDIRECTIONAL=y

How to stream the Audio from DK to earbuds ? Please help here.

I am new to this, please correct me if I made any mistakes while configuring the application.

Thanks a lot  !!!

Hello Jeevan,

Glad to hear WF-1000XM5 is supporting LE Audio now, I didn't know.

I have 1 nRF5340 Audio DK. With the steps mentioned in below links, I configured Json file to Gateway and I'm able to achieve it.

It would be easier to make sure that things are generally functioning the way they are supposed to if you had 2 AudioDKs to start out with. You are doing the building and flashing using just the script, right?

Regards,

Elfving

Hello Elfving,

Yes, WF-1000XM5 is supporting LE audio, Sony has enabled in recent update.
For building and Flashing, I am using Visual Studio Code. 

Thanks a lot !!!

I am little bit uncertain here, as I haven't tried this myself.

Though I think this is the documentation that should be relevant here. And keep in mind what it says in the note there under testing: it can be difficult to get seamless interoperability between other third party devices.

In prj.conf, added following configurations. (These configuration are referred from previously answered questions)

Could you link me to the case in which you've found these? I am not so sure about these configs here, but it might be that they are right. Could you try increasing CONFIG_CODEC_CAP_COUNT_MAX and CONFIG_BT_MAX_CONN, and see if that helps?

If it doesn't could you try enabling CONFIG_BT_BAP_UNICAST_CLIENT?

If that doesn't work could you get me a sniffer trace of this?

I can contact the relevant R&D team about this, but for that I will have to get back to you next week.

Sorry Elfving, I couldn't able to find those link(s). Once I find, will link here.

Elfving said:

And I am happy to tell you this, after increasing CONFIG_CODEC_CAP_COUNT_MAX and adding CONFIG_BT_BAP_UNICAST_CLIENT to the prj.conf file, Now I can hear the audio from both the earbuds.

Thanks a lot Elfving for the help  !!!

No problem
