Found out via discord that you have to explicitly define `CONFIG_BT_LL_SW_SPLIT=y` in the file `zephyr/tests/bsim/bluetooth/mesh/prj.conf` to get this to work. Appears nrf-sdk defaults to the nordic softdevice and you to have to override it or something...

Hi,

I'm not so familiar with the unit test. But even for simulation, you still need to include the library for it to compile. So you would need to choose one of the folders.

These are unit-tests running on babblesim (posix environment). There is no physical target.

Is the nrf52_bsim board not supported in the nrf-sdk then?

Hi pquevedo,

It seems that the compiler couldn't find the binary libraries: libsoftdevice_controller_multirole.a , libmpsl.a.
You can find libsoftdevice_controller_multirole.a in \nrfxlib\softdevice_controller\lib\cortex-m4
And libmpsl.a in \nrfxlib\mpsl\lib\cortex-m4.
YOu would need to select the library folder that match with your chip floating point configuration. Then you include in the project configuration the CONFIG_SOFTDEVICE_CONTROLLER_LIB_DIR and CONFIG_MPSL_LIB_DIR that point to the right folder.

The reason you don't have an issue with Zephyr controller is that Zephyr controller doesn't use MPSL or Softdevice controller library.
