nRF5340 Audio: Unicast Client Discovery Fails with -12 When Connecting to Headset

RE: nRF5340 Audio: Unicast Client Discovery Fails with -12 When Connecting to Headset

Hi,

Could you add CONFIG_LOG_BUFFER_SIZE=8192 and share the log? And could you please also try this with NCS 3.0.1 to see if you get the same situation occuring there?

Regards,

Elfving

Hi Elfving,

Thanks for getting back to me.

Yes — the earlier logs I shared were partial. I’ve now captured the full logs with both
CONFIG_BT_AUDIO_EP_PRINT=y and CONFIG_BT_BAP_UNICAST_CLIENT_LOG_LEVEL_DBG=y enabled, as requested.

RE: nRF5340 Audio: Unicast Client Discovery Fails with -12 When Connecting to Headset

Elfving — Tue, 29 Apr 2025 12:41:56 GMT

Are the logs attached below there what you get with CONFIG_BT_AUDIO_EP_PRINT enabled? Could you also provide the full logs, there some parts cut out from what you've provided. Could you get me the logs with CONFIG_BT_BAP_UNICAST_CLIENT_LOG_LEVEL_DBG enabled as well?

And could you also share what changes you've made to the source code, and what device you are currently testing with?

I'll ask the relevant R&D team about the rest, I'll let you know once I hear from them.

Regards,

Elfving

RE: nRF5340 Audio: Unicast Client Discovery Fails with -12 When Connecting to Headset

Yash48 — Fri, 25 Apr 2025 05:46:54 GMT

Hi Elfving,

Thanks for following up, and hope you had a great Easter break.

I enabled CONFIG_BT_AUDIO_EP_PRINT=y as you suggested — it printed out the Audio Endpoint Stream information as expected.

While investigating, I noticed that in unicast_client.c, the following arrays were originally sized based on ARRAY_SIZE(unicast_servers[cig_index][0]):

struct bt_bap_unicast_group_stream_pair_param pair_params[ARRAY_SIZE(unicast_servers[cig_index][0])];
struct bt_bap_unicast_group_stream_param group_stream_params[(ARRAY_SIZE(unicast_servers[cig_index][0]) * 2)];

 struct bt_bap_unicast_group_param group_param;
		 for (int i = 0; i < ARRAY_SIZE(group_stream_params); i++)
		 {
			 /* Every other stream should be sink or source */
			 if ((i % 2) == 0)
			 {
				 group_stream_params[i].qos = &lc3_preset_sink.qos;
				 group_stream_params[i].stream =
					 &unicast_servers[cig_index][0][device_iterator]
						  .cap_sink_stream.bap_stream;
			 }
			 else
			 {
				 group_stream_params[i].qos = &lc3_preset_source.qos;
				 group_stream_params[i].stream =
					 &unicast_servers[cig_index][0][device_iterator]
						  .cap_source_stream.bap_stream;
				 device_iterator++;
			 }
		 }
 
		 for (int i = 0; i < ARRAY_SIZE(pair_params); i++)
		 {
			 if (unicast_server->sink_ep)
			 {
				 pair_params[i].tx_param = &group_stream_params[stream_iterator];
			 }
			 else
			 {
				 pair_params[i].tx_param = NULL;
			 }
			 stream_iterator++;
 
			 if (unicast_server->source_ep)
			 {
				 pair_params[i].rx_param = &group_stream_params[stream_iterator];
			 }
			 else
			 {
				 pair_params[i].rx_param = NULL;
			 }
 
			 stream_iterator++;
		 }

When I increased the sink and source ASE counts, the CIG group creation started failing with an invalid argument error.

As a workaround for testing, I hardcoded this value.

With this hardcoded setup, the connection and audio streaming worked fine — it seemed to pick one sink and one source, ignoring the extra discovered ASEs.

Question :
How can I properly generalize this so it dynamically handles any number of sink and source ASEs discovered on the headset side, instead of hardcoding array sizes?
Is there a recommended or clean way to allocate or size these buffers based on the actual number of ASEs discovered, while ensuring bt_bap_unicast_group_create works reliably?

Additionally, I set the following to enable dual stream support:

static struct bt_bap_lc3_preset lc3_preset_sink = BT_BAP_LC3_UNICAST_PRESET_NRF5340_AUDIO_SINK_DUAL;

And defined:

#define BT_BAP_LC3_UNICAST_PRESET_NRF5340_AUDIO_SINK_DUAL                     \
    BT_BAP_LC3_PRESET_CONFIGURABLE((BT_AUDIO_LOCATION_FRONT_LEFT | BT_AUDIO_LOCATION_FRONT_RIGHT), \
                                   BT_AUDIO_CONTEXT_TYPE_UNSPECIFIED,           \
                                   CONFIG_BT_AUDIO_BITRATE_UNICAST_SINK)

This seems to enable two streams — one for left and one for right.

Question:
Is this the intended behavior — that setting both BT_AUDIO_LOCATION_FRONT_LEFT | BT_AUDIO_LOCATION_FRONT_RIGHT triggers two streams (one for each channel)?
Or is this behavior dependent on the connected headset's ASE configuration and capabilities?

RE: nRF5340 Audio: Unicast Client Discovery Fails with -12 When Connecting to Headset

Elfving — Thu, 24 Apr 2025 13:10:39 GMT

Hi again Yash, and thanks for waiting during the Easter holidays.

Has there been any development on this case in the meantime?

For this testcase, do you happen to be using earbuds from Samsung, and also enabled bidirectional feature? Could you try enabling CONFIG_BT_AUDIO_EP_PRINT=y, and sharing the log again?

Regards,

Elfving

Hi Elfving,

Thanks for the suggestion!
I tried adding the following configs as you suggested:

[quote userid="103347" url="~/f/nordic-q-a/120583/nrf5340-audio-unicast-client-discovery-fails-with--12-when-connecting-to-headset/531548"]

CONFIG_BT_BAP_UNICAST_CLIENT_ASE_SNK_COUNT=20

CONFIG_BT_BAP_UNICAST_CLIENT_ASE_SRC_COUNT=20

[/quote]

However, after doing that, I now get the following error during runtime:

In my case, the headset exposes 4 sink endpoints and 2 source endpoints, which I assume might be contributing to this issue. It seems like the increased count is causing CIG creation to fail.

Yes, I am using the nRF5340 for this setup.

Let me know if there's a recommended way to handle multiple endpoints, or if I should try tuning the count values further.

Appreciate your help !

Best regards,
Yash

Can you try adding these configurations and see if it helps?

CONFIG_BT_BAP_UNICAST_CLIENT_ASE_SNK_COUNT=20

CONFIG_BT_BAP_UNICAST_CLIENT_ASE_SRC_COUNT=20

And are you using an nrf5340 for this?

Regards and have a good week-end,

Elfving

Hi Elfving,

Yes, I am absolutely sure that I’m using the nrf5340_audio sample from the Nordic SDK, not any of the samples from the Zephyr folder.

Best regards
Yash

Are you sure you chose the audio sample from nordic, the one called nrf5340_audio? Not any of the ones from the zephyr folder?

Elfving

Yes, I am using the nRF5340 Audio DK and running the default nrf5340_audio sample application compiled in gateway mode. The NCS version I’m using is v2.9.0.

As for the headset, I’m using an actual LE Audio headset (not a DK or custom board).as I need to test with different LE Audio headsets.
