Need HFP and A2DP example to use on nRF5340 IC

[WSnyder]

I have nRF5340 Audio DK, Visual Code, nRF Connect; Simple samples like "blinky" work well.

Need an example 'Application" that provides HFP and A2Dp bluetooth that demonstrates nRF5340 IC connectivity

to android cell phone.

The nrf/applications/nrf5340_audio do not build NOR does it seem

capable of this simple task.

Hello,

Need an example 'Application" that provides HFP and A2Dp bluetooth that demonstrates nRF5340 IC connectivity

to android cell phone.

There seem to perhaps be a misunderstanding here - both the HFP and A2DP profiles are profiles in the Bluetooth Classic audio framework, whilst the nRF5340 Audio DK and nRF5340 LE Audio reference application is made for development of devices using the new LE Audio standard.
The new LE Audio standard is an improvement in every aspect compared to the Bluetooth Classic protocol, and so you will find any desired functionality from the Bluetooth Classic protocol also present in the LE Audio standard, with additional features available, increased performance and configurability, alongside the overall significant reduction in power consumption. 

For the record, none of our nRF devices have support for the Bluetooth Classic protocol.

The nrf/applications/nrf5340_audio do not build NOR does it seem

capable of this simple task.

Could you elaborate on what issues you are seeing when you attempt to build the nRF5340 LE Audio reference application?
Do you have a second nRF5340 Audio DK, or an LE Audio compatible smartphone (such as the Google Pixel 7), that can act as the peer in the connection?

Please do not hesitate to ask if you should have any questions regarding the new LE Audio specification, or if you would like to discuss the advantages the new specification would bring to your design.

Best regards,
Karl

The problem is very simple!

Our product must communicate audio to the vast cell phone user base, using HFP and A2DP.

We have tried countless Chinese ICs and modules and they all have quirks that make them

problematic for our users. We were led to believe your BlueTooth ICs could be made

to do this function (Yes or No ?)

If yes, is there a Dev Kit / IC plus example code for these functions ?

The short answer is that if you specifically need the HFP and A2DP profiles this is not something you will be able to do with a Nordic IC since these two are Bluetooth Classic profiles.The slightly longer answer is what I wrote in my previous comment; since you specifically mention and need the HFP and A2DP profiles you will need to use Bluetooth Classic (since these specific profiles are not part of the new and improved LE Audio specification, even though their functionality is present in similar, other profiles).

In essence, if you are designing a new product then I would recommend looking into the possibilities that the new standard enables (which is all that Bluetooth Classic can do, and much much more), but if you are making something that needs connectivity to an existing, older Bluetooth Classic product then you will have to use another vendors ICs that are able to do Bluetooth Classic.

Who or what lead you to believe that Nordic IC's were able to use HFP and A2DP (Bluetooth Classic) specifically?
