app_sched_event_put

[max]

Hi,

When calling app_sched_event_put inside the same hanler i am exit to main for(;;)

The main loop

for (;;)
  {
    nrf_drv_wdt_channel_feed(m_channel_id);
    app_sched_execute();//going to otaWifi_scheduler_event_handler
    //never get here
    power_manage();
  }

Scheduler event handler

void otaWifi_scheduler_event_handler(void *p_event_data, uint16_t event_size)
{
    uint32_t err_code = app_sched_event_put(NULL, 1, otaWifi_scheduler_event_handler);
    APP_ERROR_CHECK(err_code);
    //never exit to main loop from here!!!!
}

Why?

UPDATE 1

changed to:

uint32_t err_code = app_sched_event_put(NULL, 0, otaWifi_scheduler_event_handler);
APP_ERROR_CHECK(err_code);

but still not exit, go to the while loop inside "app_sched_execute":

void app_sched_execute(void)
{
    while (!is_app_sched_paused() && !APP_SCHED_QUEUE_EMPTY())
    {
        // Since this function is only called from the main loop, there is no
        // need for a critical region here, however a special care must be taken
        // regarding update of the queue start index (see the end of the loop).
        uint16_t event_index = m_queue_start_index;

        void * p_event_data;
        uint16_t event_data_size;
        app_sched_event_handler_t event_handler;

        p_event_data = &m_queue_event_data[event_index * m_queue_event_size];
        event_data_size = m_queue_event_headers[event_index].event_data_size;
        event_handler   = m_queue_event_headers[event_index].handler;

        event_handler(p_event_data, event_data_size);

        // Event processed, now it is safe to move the queue start index,
        // so the queue entry occupied by this event can be used to store
        // a next one.
        m_queue_start_index = next_index(m_queue_start_index);
    }

UPDATE 2

void otaWifi_scheduler_event_handler(void *p_event_data, uint16_t event_size)
    {
        bool finish = otaPro();
        if(finish) 
           return;
        else{
        uint32_t err_code = app_sched_event_put(NULL, 0, otaWifi_scheduler_event_handler);
        APP_ERROR_CHECK(err_code);
        //never exit to main loop from here!!!!
       }
    }

This is still problem because i need to feed a WDG in main loop!

Hi,

It’s probably not exiting because app_sched_event_put() is not returning NRF_SUCCESS. You are not using any event data, so the event size should be 0, not 1. Try this:

uint32_t err_code = app_sched_event_put(NULL, 0, otaWifi_scheduler_event_handler);

Note: If it's still not working, you need to debug and find the return value(err_code).

Hi i change, please see an update. It is still a unwanted behavior.

How are you initializing the scheduler? How does the APP_SCHED_INIT() look like?

[max]

APP_SCHED_INIT(SCHED_MAX_EVENT_DATA_SIZE, SCHED_QUEUE_SIZE); SCHED_MAX_EVENT_DATA_SIZE = 255 SCHED_QUEUE_SIZE = 150

For me, staying in while loop here is the expected behavior, isnt it? queue is never emptied that way. Something is just not designed correctly here. what do you want to achieve?
