Use native_posix and nrf5340 audio DK controller

[Reskyllr]

This question is being tested at the same time as my previous question.

I want to use linux as host and nrf5340 audio DK as controller.

for linux:

I build zephyr/sameples/bluetooth/broadcast_audio_source with native_posix

for nrf5340 audio DK:

flash to app-core:hci_usb

flash to net-core:ble5-ctr-rpmsg_3330.hex.

nrf5340 audio DK as a ble controller.

Not working properly.

For ohter le audio demo(for example:unicast_audio_client),it also not work properly.

But something is different, the error occurs when connecting, bt_smp timeout.

Can you help me test it, it is very important for our next plan?

I did quite a bit of experimentation.

I think it will ok, but there seems to be a problem with the iso:

Hi Reskyllr,

I will take over this case from Maria.

Unfortunately, you are using the host which we do not support. Additionally, please have a look at controller's limitations.

Best regards,
Dejan

Hi,Dejan.

I have solved this problem, just need to add some config in hci_usb.

i will off it.

This is great to hear! 

If you want, you could provide relevant config here for the benefit of others.

Best regards,
Dejan

I asked the developer of zephyr on discord, the problem is that hci_uart or hci_usb also needs to add iso support.
