Changes in sdk_config.h are not getting reflected in code(mesh light_switch server example)

[Prasad]

I am trying to add Timer2 to light_switch server example. But it fails to compile with a undeclared error for NRFX_TIMER2_INST_IDX. I have set the following macros in sdk_config.h.

#define NRFX_TIMER_ENABLED 1
#define NRFX_TIMER2_ENABLED 1

But it seems that this doesnt affect the code generation. I also tried to declare these macros in app_config.h but the error persists. Similar case happens with NRFX_PPI_ENABLED as well.

I am using Segger Embedded studio. I have no clue whats wrong? Is this a complier/IDE issue?

hi,

I had this issue before because it was defined else where. Search your project repository for other sdk_config.h, also if you have included directory path from the sdk it has also sdk_config.h

the apply_old_config.h contains some defines too.

Best regards

Hi,

Some additional information. The defines in sdk_config.h are only added if the same define is not already set elsewhere, which means they are overridden if you set the defines prior to including sdk_config.h. This includes preprocessor defines in project settings. You  can also use the USE_APP_CONFIG flag in order to override defines through app_config.h. See the SDK configuration header file documentation.

USE_APP_CONFIG macro is already declared in light_switch server example, but it still doest work after adding these defines in app_config.h
