How to let nRF5340 Audio DK device work as Host?

[John81]

Dear nRF team,

My requirement is that this device works as Host, and it can communicate with controller device through UART, so I have several questions:

1. How to build an Host image for this device?

2. Which pins are used for UART? If default set doesn't work, how can I configure the pins for it?

3. Can this Host used for music or call business just by UART?

Best regards,

John

BTW, UART mentioned in Q2 and Q3 is HCI UART.

Dear Team,

I have generated a hci uart hex file successfully following steps in

One of nRF5340 audio DK not working at 1M hci uart - Nordic Q&A - Nordic DevZone - Nordic DevZone (nordicsemi.com)

and uart1 works as HCI UART, which pins are p1.08, p1.09, p1.10 and p1.11.

But I am not sure how to test these functions below with a LE Audio Controller device connected by HCI UART:

1. Music through CIS with Mobile Phone that supports LE Audio.

2. Call through CIS with Mobile Phone that supports LE Audio.

3. Music through BIS with Mobile Phone that supports LE Audio? If the phone doesn't support, with bluez or others ?

Would you please give me some advices? Thanks!

Best regards, 

John
