Blinking LED managed under interrupt

Hi Dialog,

I took a look at the Smart Tag reference design to understand how you manage the LED. I saw that you use "ke_timer_set" which sends a message to the task provided as argument. I suppose that, doing that way, you cannot manage exactly the blinking timings given that you cannot predict when the message will be served, am I right?

在我众多的ion, I want to manage the blinking duty cycle to have something steady. Is it possible to raise an interrupt coming from a timer which can wake up asynchronously the system even in sleep mode (extended or sleep)?

Thanks.
Matt
