You're missing some #defines in your sdk_config.h

Because it is not enough for you to compile and link code from the SDK into your project.

You also have to recite magical incantations with regarding #define in your 'sdk_config.h'

For example: check to see if NRFX_TWIM_ENABLED is #defined somewhere. That likely will resolve your first issue.

Do you like the linux command line?

$ find $(SDK_ROOT) \( -name '*.h' -or -name '*.c' \) -exec grep <that symbol you are missing> {} \;

Where SDK_ROOT is the path to your installed SDK.

You are going to be using that. A lot.
