Replacing/Bypassing Audio codec on the nrf5340 Audio DK

[sudha_mqa]

Hello!

As part of a development initiative we are trying to use the nRF5340 Audio DK and run a different codec on it, bypassing the LC3 altogether. This new codec will be built using the existing toolchain on the chip and linked in to the build. 

Can you please suggest how we can go about this? Most forums have recommended this as the best place to go

Thank you!

Hi Sudha,

We currently only have support for the LC3 codec which is the mandatory codec for LE Audio. If you want to use another codec, you will have to make this modification work yourselves, and you will need to check and update applications/nrf5340_audio/src/audio/sw_codec_select.h  and applications/nrf5340_audio/src/audio/sw_codec_select.c depending on which codec you intend to use.

Regards,

Swathy

Hi Swathy, yes I have made the required changes to these files. I am looking for some help at the bluetooth layer, as to where changes need to be done to send different packet sizes over the channel ,etc
