Trouble with setTimeout: does not work while the screen is off

[Meztov]

Hi all 😁.

I wonder if somebody could help me, please 😅

I am working on a code based on the open source "Kearsage time for fitbit": (https://github.com/cmspooner/Kearsarge-Time-for-Fitbit-Ionic/blob/master/app/index.js) and, I can not get the alarm to vibrate when the screen is off. I have tried the function setTimeout and It do not seems be working.

I have not done changes in the function wich the alarm vibrates (remaining is the amount of minutes resting for complete a period of time):

function updatePeriodData() {

...

...
if (remaining <= 2)

{
timeRemainingLabel.style.fill = 'fb-red';
if (!didVib){
    vibration.start("ring");
   didVib = true;
 }
 else if (remaining > 2 && didVib){
     didVib = false;
     timeRemainingLabel.style.fill = 'silver';
} else {
     timeRemainingLabel.style.fill = 'silver';
}

...

...
}

But I have changed the way of call the functions, I insert "the main" in a function, for example:

function eventHandle() {
   background.onclick = function(evt) {
   console.log("Click");
   console.log("JS memory: " + memory.js.used + "/" + memory.js.total);
...

...

if (inSched){
    weatherView.style.display = "none";
    updatePeriodData();
    periodView.style.display = "inline";
}

...

clock.ontick = () => updateClock();

updateClock();

...

...

} //end function

And the "main" is:

setTimeout(eventHandle, 5000); that is my only line of code on the body.

If you need more detailed information, I would be glade of helping.

Bye!!!

Thanks!!!!!

I didn't study closely, but did you want setInterval rather than setTimeout?

The only thing that won't happen when display is off is onclick.

Thanks for your response, let me check, I just hae tried with setTimeout. Thanks!

I have only tried**

Hi, sorry.

I have tried both functions now, and setInterval do not fire the alarm.

Is there any other function I can use for activate an alarm at a certain time? I do not find much information, maybe I do not know were to looking for. I still stuck with making the alarm vibrate while the screen is of.

Thanks!!!!!
