nRF5340_Audio

[Min]

Hello LE-Audio team,

By any chance, do you have a working code base that supports a headset with 2 end points instead of just one as your sample nRF5340_Audio kit?

If yes, will you please let me know how I can get it?

If not, what do I have to do to change the current nRF5340_Audio project to support a real two channel headset?

Thank you.

Hi Min,

Could you try adding CONFIG_BT_BAP_UNICAST_CLIENT_ASE_SNK_COUNT=20 CONFIG_BT_BAP_UNICAST_CLIENT_ASE_SRC_COUNT=20.?

Our gateway already supports TWS stereo. Please also let us know which TWS you are working with.

Regards,

Swathy

Hi Swathy,

I moved past this, now the issue is as follows:

GW [00:00:15.574,920] <wrn> bt_hci_core: opcode 0x2062 status 0x07
GW [00:00:15.574,920] <wrn> bt_iso: Unexpected response to hci_le_set_cig_params
GW [00:00:15.574,951] <err> bt_bap_unicast_client: bt_iso_cig_create failed: -5
GW [00:00:15.574,981] <err> unicast_client: Failed to create unicast group: -5
GW [00:00:15.574,981] <err> unicast_client: Failed to start unicast sink audio: -22

The root cause is:

GW [00:00:15.574,920] <wrn> bt_hci_core: opcode 0x2062 status 0x07

status 0x07 is: #define BT_HCI_ERR_MEM_CAPACITY_EXCEEDED        0x07

Therefore, I am out of memory for HCI.

Please help me as how to increase the memory used by HCI. Which memory allocation do I need to increase and in which config file?

If I set to those numbers above, my memory problem is more severe.

Options I expect:

1. have do increase the HCI memory, but I don't know how exactly if this is the cause.

2. do you have a release pull just for this TWS 3rd party earbuds with all the correct settings for NCS3.0.2?

Thanks.
