nRF5340 audio log errors

[gfgf2400a]

Hi,

I programmed network core ble5-ctr-rpmsg_3303.hex with nrfConnect programmer. I then used VS code to run/debug nrf5340_audio_dk_nrf5340_cpuap.

Please let me know why I am seeing:

. <wrn> ble: Failed to create ID

. <wrn> bt_hci_core: Controller to host flow control not supported

Thanks,

Hello,

. <wrn> ble: Failed to create ID

This is generated when the call to bt_id_create fails. The patch for this can be seen in this PR.

. <wrn> bt_hci_core: Controller to host flow control not supported

The LE Audio controller does not support HCI flow control, which is why this warning is generated when BT is enabled.

Best regards,
Karl

Hi,

What do I need to fix this? Modify ble_core.c?

This is the sample code provided with nrf5340 audio dk. Should the sample code works without any code change? May be I am missing something here.

Thanks

Which nRF Connect SDK version are you on?
If you are on a version prior to the PR I linked you can indeed incorporate it into your project to resolve the warning.

The nRF5340 Audio reference application should function without any modification of the code, yes. Are you experiencing any issues with the functionality when programming your nRF5340 Audio DKs with the default nRF5340 Audio reference application?
If so, please elaborate on what kind of issues you are experiencing.

Best regards,
Karl

I think the log shows "NCS Version: 2.1.1" which indicated nRF Connect SDK version 2.1.1.

Again, the asked problems as in my original ticket:

Please let me know why I am seeing:

. <wrn> ble: Failed to create ID

. <wrn> bt_hci_core: Controller to host flow control not supported

Please read this ticket. Thanks
