Hi,

I can really say. It was just a gut feeling, and when I tested it seemed to be correct.

You are absolutely right!

But I am wondering, just for my own knowledge, how you managed to catch that just from the error code I provided?

Hi,

Based on the error it seems like you put the call to APP_SCHED_INIT() outside a function. The tutorial states you should write the line with the call to APP_SCHED_INIT() "above your main loop", which is not to be confused with above your main function. To be clear, your main function should look like the following after that step:

int main(void)
{
    lfclk_request();
    log_init();
    gpio_init();
    timer_init();

    NRF_LOG_INFO("Scheduler tutorial example started.");

    APP_SCHED_INIT(SCHED_MAX_EVENT_DATA_SIZE, SCHED_QUEUE_SIZE);

    // Enter main loop.
    while (true)
    {
        __WFI();
    }
}
