getting undefined reference error

Hello,

Please make sure that the module's are enabled in the sdk_config.h file as well, and that you have added the source code files to your project through the project navigator in SES.

Best regards,
Karl

I enabled the modules in sdk_config.h still getting the errors

Please also confirm that you have added the source files to your project, and that you have added the path to the files into the User Included Directories in the Preprocessor project options for the Common configuration.

Best regards,
Karl

Thanks, karl but I did that earlier and check again path is set in preprocessor option still getting the same errors

Please show me the sdk_config configurations you added along with a screenshot of the preprocessor user included directories and a screenshot of the added source files so that I may take a look to see if I can spot the issue.

Best regards,
Karl

You should use either relative or absolute paths in your project, and since the SDK is based on relative paths I would recommend that you add new directories using relative paths as well. Please also make sure to have no trailing whitespaces in the included directory paths - please confirm that this is not the case.

Furthermore, I can not see that you have enabled the BSP BLE button configuration since you do not have the following in your sdk_config.h

#ifndef BSP_BTN_BLE_ENABLED
#define BSP_BTN_BLE_ENABLED 1
#endif
