Learn nrf9160 asset_tracker_v2

[john.liu]

Hi:

 I use ncs v2.2.0 and asset_tracker_v2 example.

 \asset_tracker_v2\src\modules\led_module.c

learning:

static bool app_event_handler(const struct app_event_header *aeh)
{
	if (is_led_state_event(aeh)) {
		return handle_led_state_event(cast_led_state_event(aeh));
	}

	/* If event is unhandled, unsubscribe. */
	__ASSERT_NO_MSG(false);

	return false;
}

I can't find the source files of is_led_state_event  and cast_led_state_event.

Hi

The is_led_state_event and cast_led_state_event is marcos created during compile of the project by the application event manager. The nearest source I think you will find is the  inside the led_state_event.h 

struct led_state_event {
	struct app_event_header header; /**< Event header. */

	enum led_state state;
};
