Trying to Build Channel sounding example for nRF54L15, but wasnt able to build it for the board

[Adhil Xavier]

For a project i need to use the channel sounding feature of bluetooth. On checking samples on nRF Connect SDK couldn't find any examples. But the Zephyr project is providing an example code for both reflector and initiator roles. I was trying to build the project for nRF54L15, because in the zephyr documentations it was mentioning this chip is supporting channel sounding. After setting up zephyr build environment i tried to build the initiator sample with the command "west build -b nrf54l15dk/nrf54l15/cpuapp samples/bluetooth/channel_sounding/cs_test/initiator"
But wasn't able to build the sample as it was disabling the configuration specifically CONFIG_BT_CHANNEL_SOUNDING. I had set the configuration enabled but on compilation it is overriding and setting to disabled. Since the config is disabled i'm getting linker error(undefined reference to function) since the sources are not added to project while building

Build logs SS is attaching here for reference.

Hi Adhil

As of NCS 2.8.0, we added experimental support for Bluetooth channel sounding, and also a sample available here for a CS reflector and ranging responder. In your sample here I guess there is some dependencies not being satisfied.

Best regards,

Hi Simon,
Thanks for the reply. The version i'm using now is 2.8.0 but it doesn't have a sample for channel sounding. On further checking the git of nrf connect SDK i was able to find that the changes are their in main still need to merge with v2.8.0 branch. Could you please confirm that the sample is there or guide me an alternative to build the sample. Im trying now agin with zephyr build environment i have added the dependency configurations in prj.conf. But after adding dependencies it shows those configurations are not user configurable, attaching SS for your reference.
