k_timer_status_sync never triggers

NCS 2.0.0

I start a timer using k_timer_start with a duration of multiple seconds (ive tried 10, 30, and 60) but the immediate next line of code (k_timer_status_sync) never completes and moves on the next line, a simple print statement to tell me it's done. I'm not using any power management of any kind.

Hello

Could you please share how you define and start your timer?

Best regards,

Einar

struct k_timer ble_adv_timer;

k_timer_init(&ble_adv_timer, NULL, NULL);

k_timer_start(&ble_adv_timer, K_SECONDS(10), K_NO_WAIT);

k_timer_status_sync(&ble_adv_timer);

      printk("Synched\n");

[Einarh]

Yes I am aware that K_NO_WAIT is defined, but I don't see how it makes sense as a timer period.

have you tried setting your period to 10 seconds?

[JGusler]

Having that as a period makes it a one time timer, according to the provided guides. Which is all I want because all I'm doing there is advertising for 10 seconds and then shutting the chip down

[Einarh]

ok I see

I tested exactly what you posted in your first comment now, and it worked, printing synched after 10 seconds. (on an nRF52840 DK)

Are you doing anything else in your program that could effect timing?

[JGusler]

Using threading, maybe it's switching to the idle thread and dropping that work thread?

[Einarh]

hm sounds strange, k_timer_status_synch is supposed to be blocking.

I would suggest you try to make a more minimal program to verify that you get the timer to work on your setup, then add the parts of your program piece by piece to find out what makes it stop working.
