- * @{
- * @ingroup app_common
- *
- * @brief The scheduler is used for transferring execution from the interrupt context to the main
- *        context.
- *
- * @details See @ref seq_diagrams_sched for sequence diagrams illustrating the flow of events
- *          when using the Scheduler.
- *
- * @section app_scheduler_req Requirements:
- *
- * @subsection main_context_logic Logic in main context:
- *
- *   - Define an event handler for each type of event expected.
- *   - Initialize the scheduler by calling the APP_SCHED_INIT() macro before entering the
- *     application main loop.
- *   - Call app_sched_execute() from the main loop each time the application wakes up because of an
- *     event (typically when sd_app_evt_wait() returns).
- *
- * @subsection int_context_logic Logic in interrupt context:
- *
- *   - In the interrupt handler, call app_sched_event_put()
- *     with the appropriate data and event handler. This will insert an event into the
- *     scheduler's queue. The app_sched_execute() function will pull this event and call its
- *     handler in the main context.
- *
- * @if (SD_S110 && !SD_S310)
- * For an example usage of the scheduler, see the implementations of
- * @ref ble_sdk_app_hids_mouse and @ref ble_sdk_app_hids_keyboard.
