nRF5340 audio DK, CONFIG_BT_SHELL, Gateway issue

[MStreet]

I've successfully built and run the latest nrfF5340_audio (2.3.0-rc1) application for both headset and gateway and am now trying to add the BT shell. Headset builds and runs, but gateway gives many errors. I eliminated the duplicate definition of "unicast_client_cbs" as described in another post. Shell related configs in prj.conf are:

# Shell related defines

CONFIG_SHELL=y

CONFIG_KERNEL_SHELL=y

CONFIG_USE_SEGGER_RTT=n

## Disable logs on RTT

CONFIG_SHELL_RTT_INIT_LOG_LEVEL_NONE=y

CONFIG_SHELL_BACKEND_RTT=n

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=y

CONFIG_SHELL_HISTORY=y

# BT Shell

CONFIG_BT=y

CONFIG_BT_CENTRAL=y

CONFIG_BT_SHELL=y

CONFIG_BT_FILTER_ACCEPT_LIST=y

# Turn off default shell commands

CONFIG_I2C_SHELL=n

CONFIG_HWINFO_SHELL=n

CONFIG_CLOCK_CONTROL_NRF_SHELL=n

CONFIG_FLASH_SHELL=n

CONFIG_DEVICE_SHELL=n

Here are the warnings and first of many errors that are shown before it exits:

Hello,

Just letting you know that I have been assigned your case and will look into it after the weekend.

Best Regards,
Maria

Hello,

I have reproduced this issue, but not resolved it. Thank you for your significant patience with this.

Best Regards,
Maria

Hello again,

Thank you for your patience.

We don't recommend using BT_SHELL with the nRF5340 Audio application. The reason for this is that the source files needed for media control conflicts with the source files for Bluetooth shell.

Another thing to consider is that BT_SHELL is can interfere with the gateway setting up streams and make the setup fail.

Best Regards,
Maria

OK. There are a few BT commands, such as "connections" that are useful for my application that I have been able to copy to my own shell that shouldn't be an issue. Thanks.
