The purpose of NRF_MODULE_ENABLED

[SergeyP]

While creating my own service I used ble_app_blinky as an example, once I opened ble_lbs.c file I saw it contains the service's declaration inside the macro:

#if NRF_MODULE_ENABLED(BLE_LBS)
...

#endif

Would I benefit if I follow the same pattern by leveraging that macro while defining my own services? If so - what is the purpose of the macro and what I should pass as the parameter? The brief documentation provides very little of the information, so I would like to understand what "module" in this context mean and where/how it could/should be enabled/disabled.

Hi,

This macro is used for checking if the module is enabled in the SDK configuration header. The parameter should be the module name. The definition of the macro is shown below. If appends the _ENABLED postfix to the parameter and checks if it is defined. In this case it will simply check that BLE_LBS_ENABLED is defined.

#define NRF_MODULE_ENABLED(module) \
    ((defined(module ## _ENABLED) && (module ## _ENABLED)) ? 1 : 0)

Best regards,

Jørgen
