NRF5340 audio DK: CIS Mode using the Zephyr LE Controller

[Reskyllr]

When i update ncs 2.4.0. I found a "nrf5340_cpunet_cis-bt_ll_sw_split.conf" in zephyr/sample/bluetooth/hci_rpmsg.
That means zephyr le controller supports le audio and 5340 audio demo?

But I will use this conf and compile hci_rpmsg, and then use the following command to burn to net_core

nrfjprog -f NRF53 --coprocessor CP_NETWORK --program build/zephyr/zephyr.hex --chiperase

The LED on the development board turns red (indicating a problem),but in rtt console i don't see any output (log level2).

If we swap back in the Packetcraft LE controller everything works as expected.  

How can I use it to work in the 5340audio demo, I saw it is possible in this thread(devzone.nordicsemi.com/.../nrf5340-audio-development-kit---cis-mode-using-the-zephyr-le-controller---gatt-discovery-fails-due-to-0x05-bt_att_err_authentication), can you help me to test the feasibility?

The reason is that I want to include classic bluetooth in it, which is important for our work.

Hello Reskyllr, 

That means zephyr le controller supports le audio and 5340 audio demo?

The Zephyr controller is being worked on to support LE Audio, but I believe everything isn't there yet. So there are some zephyr samples that do support different parts of LE Audio, though not necessarily all. Our LE Audio application however is not supported by the zephyr controller yet.

The answer by my colleague in the case you linked to answers this very well; you might be able to run parts of the application, but the audio application is currently not designed for the zephyr controller in mind. For more details on support for different controllers though, I would recommend that you contact your local RSM (let me know if you do not know who this is).

The reason is that I want to include classic bluetooth in it, which is important for our work

I see. The Packetcraft controller does allow for normal BLE alongside LE Audio, but it would be a bit more difficult to use Bluetooth Classic. Have you considered using a separate chip for that?

OK, I got it, but I have some questions about the Packetcraft controller, I will open a new ticket.

Thanks,
