nRF5340 audio DK, CONFIG_BT_SHELL Question

[gfgf2400a]

Hi,

I am using nRF Connect SDK v2.1.1 with nRF5340 audio DK PCA10121. I am able to have LC3 audio CIS example code working for gateway and headset. I turned on CONFIG_BT_SHELL to be enable BT shell for cmd_fal_add() but I got into compiler error. Here are my prj.conf configuration:

# Shell related defines

CONFIG_SHELL=y

CONFIG_KERNEL_SHELL=y

CONFIG_USE_SEGGER_RTT=y

## Disable logs on RTT

CONFIG_SHELL_RTT_INIT_LOG_LEVEL_NONE=y

CONFIG_SHELL_BACKEND_RTT=y

CONFIG_SHELL_BACKEND_SERIAL=y

CONFIG_SHELL_VT100_COLORS=y

CONFIG_SHELL_STACK_SIZE=4096

CONFIG_SHELL_CMD_BUFF_SIZE=128

## Reduce shell memory usage

CONFIG_SHELL_WILDCARD=n

CONFIG_SHELL_HELP_ON_WRONG_ARGUMENT_COUNT=n

CONFIG_SHELL_STATS=n

CONFIG_SHELL_CMDS=n

CONFIG_SHELL_HISTORY=y

CONFIG_BT=y

CONFIG_BT_CENTRAL=y

CONFIG_BT_SHELL=y

CONFIG_BT_FILTER_ACCEPT_LIST=y

The compiler error is:

c:/ncs/toolchains/v2.1.1/opt/zephyr-sdk/arm-zephyr-eabi/bin/../lib/gcc/arm-zephyr-eabi/10.3.0/../../../../arm-zephyr-eabi/bin/ld.exe: zephyr/subsys/bluetooth/shell/libsubsys__bluetooth__shell.a(audio.c.obj):C:\Projects\le-audio\gateway\zephyr\subsys\bluetooth\shell\audio.c:607: multiple definition of `unicast_client_cbs'; app/libapp.a(le_audio_cis_gateway.c.obj):C:\Projects\le-audio\gateway\gateway\src\bluetooth\le_audio_cis_gateway.c:195: first defined here
collect2.exe: error: ld returned 1 exit status
ninja: build stopped: subcommand failed.
FATAL ERROR: command exited with status 1: 'c:\ncs\toolchains\v2.1.1\opt\bin\cmake.EXE' --build 'c:\Projects\le-audio\gateway\gateway\build'

When I comment out unicast_client_cbs in either audio.c:607 or le_audio_cis_gateway.c:195, I got different compiler errors. Do I need another CONFIG_BT option, that I don't see, for nRF Connect SDK v2.1.1 with nRF5340 audio DK PCA10121?

Thanks,

Dennis

Additionally, you should consider upgrading to NCS v2.2.0. Please let me know if these changes work for you in both NCS v2.1.1 and v2.2.0.

I updated the CONFIGs for v2.1.1 and I did get v2.2.0. Same problems in both SDK. I read and looked at the compiler error. It is duplicated unicast_client_cbs in \gateway\zephyr\subsys\bluetooth\shell\audio.c:607 and \gateway\gateway\src\bluetooth\le_audio_cis_gateway.c:195. This is why the audio example works when CONFIG_BT_SHELL=n

[gfgf2400a]

I really need more information to get CONFIG_BT_SHELL=y working

[gfgf2400a]

To fix this, in \gateway\zephyr\subsys\bluetooth\shell\audio.c, I renamed unicast_client_cbs to audio_unicast_client_cbs to remove the duplicates

Finally, I got this:
