Warnings [Pg004] macro parameter "__VA_ARGS__"

[annapalu]

Hi all,

i have a little problem with the #define NRF_LOG. I have this warnings, and i don't know why.

Warning[Pg004]: macro parameter "VA_ARGS" is used in both expanded and raw forms

Someone have an idea about the reason?

Thank you, Anna

The easiest way to fix this is just to add a second set of braces:

NRF_LOG((NRF_LOG_COLOR_RED "\n*** ASSERTION FAILED ***\n"));

This seems to force the preprocessor to perform the string concatenation before attempting to expand the NRF_LOG macro.
