When compiling nef5340 audio device, LC3 encoding and decoding mode is selected, and the header device is not available

JiaLiu

1，We put LC3 folder in NCS_ 1.9.99_ dev\ncs\nrf\applications\nrf5340_ Under audio\src, modify the makefile and compile it.

2，Migrate the LC3 library to NRF audio and set config config_ SW_ CODEC_ Lc3=y, use the following compilation command:

     python buildprog. py -c both -b debug -d both -p

The gateway device is normal and the green light is on.

The red light of the headset device is on, and an exception occurs.

Through log analysis, when the header device is initialized, although SW is set_ codec_ cfg. sw_ codec = SW_ CODEC_ LC3;

But when calling SW_ codec_ Init,

m_ config. sw_ codec != SW_ CODEC_ LC3，

Cause SW_ codec_ lc3_ Init failed.

    Hello!

    I would advise you to upgrade to NCS v2.0.0, as it contains major updates relevant to BLE Audio support, unless you have very good reasons to stay in 1.9.

    Let me know if you still have issues with this.

    Best regards,

    Einar
