Issues while flashing nrf5340 audio application

[akhil]

Hey,

So I was trying to flash the audio application on my nRF5340 audio dk. I built the program successfully using the buildprog tool provided.

The problem here is, I only have 1 development board. Is it possible to get the program working on just 1 DK?

If yes, How do I configure it to fetch audio from either BLE (connected to my phone) or LINE IN (connected to the audio jack) and then route it to the speakers connected to the Headphone OUT jack.

PS: These are the things happening after flashing the audio application

If I flash the gateway build, the RGB led in the center starts flashing green and so does LED3.

If I flash the headset build, the RGB led in the center starts flashing blue and so does LED3.

Hello,

You can program the Audio Application from the SDK, but for testing the applications within the SDK, you need more than one Audio DKs. Take a look at this page about Audio Applications. There, you can find a section on the minimum number of DKs required for testing each application.

Kind regards,

Hello,

Yes I'm aware that you need multiple Audio DKs to test the audio applications. But that simply isn't viable in our project case. I need to configure the audio application in such a way that it can connect my Audio DK to my mobile via BLE and I can stream audio from my mobile to the speakers connected to the headphone out jack. I have gone through the audio application myself and considering its complexity, I couldn't achieve the above myself. It would be great if you could help me achieve the above mentioned contraption.

Hi,

Have you built nrf5340_audio application for headset on your nrf5340_audio-dk?

Which mobile phone do you plan to use in your setup? Have you checked if your mobile phone supports LE Audio?

Yes, I have already mentioned above that after flashing the application as headset on my audio dk, the RGB in the middle keeps flashing blue. I'm assuming the board is being reset as LED3 also keeps flashing (correct me if I'm wrong).

I'm using Samsung S20FE and yes it does support LE Audio.

Hi,

I would recommend that you double-check if S20FE phone supports LE Audio. 

Have you enabled LE audio feature on your phone?
If LE Audio is enabled on the phone, it should work fine with our CIS headset.

Hey,

I have tried using my iPhone 13 as well. My original question is still unanswered tho. Is it possible to get the program working on just 1 DK? specifically in unicast server mode (CIS) so it can fetch audio data from my mobile device and play it via the speakers?

Yes, this should be possible. You can read more in this discussion.
