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,

I just want to clarify that the software still work and I can ignore this log warning:

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

Thanks

Hello Dennis,

Yes, the program will work with this warning still present, you can indeed ignore it :) 
It is present to alert you to the fact that controller to host flow control is not supported, in case you intended to use this with the LE Audio controller.

Please do not hesitate to ask if you should have any additional questions about this, or feel free to open another ticket if you should have any questions that diverge from the original questions in this ticket.

Best regards,
Karl
