TX power reduction with bap_broadcast_source

Axelle

Hello, 

I'm trying to reduce the range of transmission of the nRF5340 SoC for an Auracast Broadcast. I would like it to be detectable only from a distance of 1 or 2 meters.

I've tried to force the TX_PWR to -20 dB in the configuration menu (west build -t menuconfig), but every time I try to build the project, there are configuring errors :

CMake Error at C:/ncs/v2.8.0/zephyr/cmake/modules/kconfig.cmake:396 (message):
command failed with return code: 1
Call Stack (most recent call first):
C:/ncs/v2.8.0/nrf/cmake/modules/kconfig.cmake:29 (include)

C:/ncs/v2.8.0/zephyr/share/zephyr-package/cmake/ZephyrConfig.cmake:97 (include_boilerplate)
CMakeLists.txt:4 (find_package)

Has anyone encountered this issue and resolved it?

    Hi Axelle,

    Thank you for additional information.

    I've tried to force the TX_PWR to -20 dB in the configuration menu (west build -t menuconfig)

    Can you show how you did this? Is your change reflected in the final merged build configuration .conf located in build\zephyr folder? Can you show your .conf file?

    every time I try to build the project, there are configuring errors

    Can you show complete log?

    I would like it to be detectable only from a distance of 1 or 2 meters.

    Can you clarify this? From which-to-which distance you want it to be detectable?

    Best regards,
    Dejan

    I use this command : west build -t menuconfig to get in the configuration menu, then I travel to  Subsystems and OS Services/Bluetooth/Bluetooth Controller/Tx Power : 

    Yet even saving the file, I cannot see any difference in the .config file

    .

    After configuring, even without seing anything in the .config file, I'll have this error log :

    I would like for the broadcast to be detectable from 0 to 2 meters
