CONFIG_BT_LL_NRFXLIB_DEFAULT causes prj.conf:9: warning: attempt to assign the value 'y' to the undefined symbol BT_LL_NRFXLIB_DEFAULT

Blue King

trying to build a long range coded phy broadcast/scanning application. as I know zephyr doesn't support that so we have to include nordic link layer based on this post

https://devzone.nordicsemi.com/f/nordic-q-a/62619/coded-phy-advertising-on-nrf-connect-sdk/255352#255352

the problem is, Zehpyr can't see the NRFxlib

I followed this tutorial to install NRFx with zephyr with no luck

https://jimmywongiot.com/2019/12/18/step-by-step-on-nordic-connect-sdk-for-development/

tried also to copy the nrfxlib and import the kconfig file into my zephyr enviroment.

https://github.com/nrfconnect/sdk-nrfxlib

actually, I find nowhere in any file on nrfx library this text "LL_NRFXLIB"

tried also to include CONFIG_SOFTDEVICE_CONTROLLER_S140 with no luck.

so, What do i miss?

I always get

prj.conf:9: warning: attempt to assign the value 'y' to the undefined symbol BT_LL_NRFXLIB_DEFAULT

this is my prj.conf

CONFIG_BT=y
CONFIG_BT_BROADCASTER=y
CONFIG_BT_OBSERVER=y

    Hi,

     

    Have you checked out zephyr upstream instead of the NCS forked sdk-zephyr?

    You can check this by entering the path/to/ncs/zephyr and writing "git remote -v". It should show:

    13:59 $ git remote -v
ncs	https://github.com/nrfconnect/sdk-zephyr (fetch)
ncs	https://github.com/nrfconnect/sdk-zephyr (push)

     

    Kind regards,

    Håkon

    this is what it shows. I believe it's ok

    ~/sources/zephyrNrf/ncs/zephyr$ git remote -v
    ncs     github.com/.../sdk-zephyr (fetch)
    ncs     github.com/.../sdk-zephyr (push)

    Hi,

     

    Does this happen if you try to enable LL_NRFXLIB on any other example as well?

    Is there a specific sample that fails?

     

    Could you paste the full build log?

     

    Kind regards,

    Håkon

    do I have conflicting configurations? from where to understand/read more about that?

    Hi,

     

    The former path for sdk-zephyr looks to differ from the one that west if finding now.

    ~/sources/zephyrNrf/ncs/zephyr$ git remote -v

    ncs github.com/.../sdk-zephyr (fetch)

    ncs github.com/.../sdk-zephyr (push)

     While your current build if fetching:

    Blue King said:
    /home/blueking/sources/zephyrproject/zephyr

    source the zephyr: ~/sources/zephyrNrf/ncs/zephyr/zephyr-env.sh

    And try to re-configure outside the upstream zephyr (ie: sources/zephyrproject/zephyr catalog).

     

    Kind regards,

    Håkon
