2 NRF5340 AUdio DK's both as central?

[Jorritv3]

I want to connect 2 nrf5340 Audio DK's together and have them share audio data over a bluetooth connection, however I also want every device to have a connection to its own peripheral at the same time. 

This means that both DK's function as a dual-role but also need to connect together.

How would I be able to achieve this?

Any help is welcome, thank you in advance!

Thank you very much, indeed both devices would need to encode and decode 2 streams, so good to keep the budget in mind. 

Thank you for your help!

The team confirms that this process would result in 90%, as you are doing this in both directions.

The CPU is slightly lower when doing 16kHz, so it might still work. I guess also that the two devices in the middle here doesn't use USB, so that is not using much CPU. You should also make sure you are not resampling from 16kHz to 48kHz in every device, so make sure to disable the sample rate converter by setting CONFIG_SAMPLE_RATE_CONVERTER=n

EDIT: If you are able to describe a bit further what you are trying to achieve, we might be able to guide you to a simpler way to achieve it though.
