LE Audio Code Migration Need tools

Current experimental platform and environment
Test platform: BT631D (NRF5340)
SDK version: NCS2.3.0


nRF5340 Bluetooth 5.3 Module Matter & LE Audio FSC-BT631D


Product Overview

Need to implement LE audio content

LC3 encoding and decoding

LE transmission encoding data

Support for multiple streaming functions

Support CIS unicast audio function

Support BIS broadcast audio function


Embed protocol stack contents

The execution sequence and flowchart are shown below

The gateway receives audio data from the audio source.

The gateway processes audio data in its application core and transmits data through the application layer:

The host sends the encoded audio data to the network kernel subsystem (controller).

The subsystem forwards audio data LE to the hardware radio and sends it to the headphone device.

The headphone receives encoded audio data on the network core.

The network kernel subsystem (controller) sends encoded audio data to the LE host on the headphone application core.

Headphones process audio data in their application cores, which transmit data through the application layer:

The decoded audio data is sent to the hardware audio output through I2S.



Attention points

Le audio is currently a new technology with few mature product solutions on the market, complex engineering, and many problems that need to be solved!


Summary

The LE audio code migration process is very complex, but the BT631D module testing results are relatively good after migration.
