Scheduler library examples

[Ars Morozov]

Hi,

I'm discovering documetation of the Scheduler library. So, as I understand the idea is to call function app_sched_event_put(...,some_func) from the interrupt/event handler and then passed some_func will be executed from the main. app_sched_execute()  should be added to main loop. Everything is clear. There are also some examples: HID Mouse Application and HID Keyboard Application. But in this examples I don't see in main.c any calling of the app_sched_event_put() function. It seems that main application doesn't use the Scheduler, only internal SDK components such as app_timer use it. 
Is it mistake or I don't understand something?

Hi,

There is a scheduler tutorial available here on DevZone.

Best regards,

Also, one more question regarding Scheduler. If I set NRF_SDH_DISPATCH_MODEL  1, so is it correct that all BLE events will be passed to main context? If yes, what will be with data the pointer to which passed to the sheduled handlers? For example if I have BLE_GATTS_EVT_WRITE event I want to handle written data, thus I need a pointer to this data. In case if I receive normal interrupts, then I receive the pointer to the data, which are valid only while interrupt is handling. But if I receive this interrupt in the main context, what will be with this data? Where they will be stored and how long?

The difference between APPSH and INTERRUPT method is only that the SDH library will schedule a call to the SDH function that polls the events from the softdevice, when the softdevice interrupt happens, in the APPSH method, instead of calling it directly like it is done in the INTERRUPT method. The event/data pointers will be valid/received in the same way for both methods.

Thank you for the answer.
