Handling Blink timers and using LED one-shot

[CT_Engr]

Hi,

I have a app that using a constantly blinking LED started at power-up, however I am having some trouble stopping the timer.. (Yes, I know it's simple.. but i still cant figure out where)

This is my timer

err_code = bsp_init(BSP_INIT_LED, APP_TIMER_TICKS(8, APP_TIMER_PRESCALER), NULL);

How do I turn it off? (stopping the timer)..I need to destroy this timer in bsp_init I think) app_timer_create(&m_leds_timer_id, APP_TIMER_MODE_SINGLE_SHOT, leds_timer_handler);

I have another question .. in another post someone asked for a 1 second Timer (one shot) and this code below was suggested to turn off an LED using a temp timer.. and also referred to rtc1.h. Is this usable in use PCA20006 for SMART BEACON??? I can't find the header or any reference to rtc1_timeout_set_ms in samples.

This was the code suggested in the other post.

static void ledice (void)
{    
        
        rtc1_timeout_set_ms(500);

        LEDS_ON(BSP_LED_0_MASK);

        while (!rtc1_timeout()) { }   

        LEDS_OFF(BSP_LED_0_MASK);
}

Sorry for these questions... to be honest, I am just bad at timer irqs... sorry

Thanks JJ

The bsp module is indeed not easy to use and we are working on improving it.

The bsp module uses one shot timer and starts a new timer in the event handler based on the state. If the state is IDLE it will not start a new timer, hence this is the way you stop the constant blinking. You can set the state with:

uint32_t err_code = bsp_indication_set(BSP_INDICATE_IDLE);
APP_ERROR_CHECK(err_code);

You should use app_timer and not rtc1.h. App_timer uses the RTC1 peripheral so if you try to use both app_timer and rtc1.h you will run into trouble. See this tutorial on how to use the app_timer module.
