Stethoscope using nrf5340-audio

[Vivek]

We are developing digital stethoscope and would like to use nrf5340-audio DK as starting point. We need to first get the microphone out on the headphones jack in the DK and also to transfer the microphone voice data over bluetooth to our BLE headphones (5.3).

Is there any application reference or guidance on this so that we move on to our custom board as fast as possible?

Hi,

All our kits have all the schematics and hardware files available for reference if that is what you are looking for. 

We also have just the recommended ref design from the product specification\Datasheet

Oh, 

The hardware design is not an issue as we already have designed three produts using the nrf5340.

We are talkign about the VS code project where we get the microphone out on the headphones jack in the DK and also to transfer the microphone voice data over bluetooth to our BLE headphones (5.3).

right now the plroject given in the Application is using two EVK boards.

Thanks for the explanation that did help. 

Currently we don have a sample that matches this setup exactly. 

You can see all our samples here https://docs.nordicsemi.com/bundle/ncs-2.9.0/page/nrf/applications/nrf5340_audio/index.html 

I am asking internally to see if we have have any other samples or some showcase code here that we can share.

Jonathan
