feature request: increase refresh rate to 1min

[zibra]

We are using Freestyle Libre 3 sensor which gives BG reading to nightscout every minute. Is it possible to increase refresh rate on Nightguard as well to 1min?

[zibra]

I've found backgroundTaskScheduleRate setting, but it seems like the only way to configure it to make custom app build? It will be best to expose this as configurable setting

[dhermanns]

Yes - this is currently not supported, since no sensor was able to send every minute data.
Problem is I don't have a freestyle libre to continuously test such a feature.

[zibra]

@dhermanns could you build IPA with such settings so I will test it on my end?
I've tried to build project on my end but getting this error:

[dhermanns]

I had to make a small Addon to the Eureka SliderRow:

public final class SliderRow: Row<SliderCell>, RowType {

    public var steps: UInt = 20
    public var shouldHideValue = false
    public var lastSelectedValue : Float?

    required public init(tag: String?) {
        super.init(tag: tag)
    }
}

That should fix it. Would be great if you can provide a Configuration-Option for that.

Hello, Just curious....is there an update on this question, as it is open since dec2022? Many libre 3 are being used now.

I was going to ask the same thing. My son at school uses the libre3 now and it would be great to be able to have a toggle to decrease the refresh time

[dhermanns]

For me it's still the same: I don't have a libre3 and therefore cannot implement and test this. So we need someone who can test and support this.

I have libre3 and can test this. But I would need some input, I am not a skilled programmer. I have a working build environment here.

It seems that
backgroundTaskScheduleRate
was removed in the meantime? Can the 5 minute intervall be changed somewhere now?

I also noticed, that, when the app on the watch is open, it is updated rather often, but it seems to get stuck also often, then I have to use the reload arrow on the second page. Is that normal behaviour? While the app is in forground should it not continue to update?

[dhermanns]

A lot of refactorings in the meantime. But the updates frequency should still be changed very easily, since its done using a timer.

Never noticed that updates on the watch should get stuck. Yes, I would expect them to be updated every 5 minutes if the app stays in foreground.

[poml88]

Ok, I see. I am still not so familiar with the code. I did not find that timer yet. If you have a hint... ;-)

[dhermanns]

In the iOS App the timer is in the MainViewController. It already activates every 30 seconds. It uses the NightscoutCacheService.singleton.loadCurrentNightscoutData to get the latest data.

The method checkIfRefreshIsNeeded in this Service restricts the updates to 5min only.

[poml88]

Thanks, ok, found it. The currentNightscoutData.isOlderThan5Minutes() is quite hard coded... And the app quite complex. I will see if I can come up with something. A func isOlderThanXMinutes(_ minutes : Int) is already there and could be used. Have to add the switch in the preferences...

[poml88]

So, I made a testflight build with an option to select 1 minute updates. Seems to work. Where do we go from here? You want to try it out?
I would have some other questions as well, Is there a way to get in touch?

[dhermanns]

Hi Phil! Simply provide a Pull Request. I will have a look. But keep in mind that you will have to provide support for this feature, since I'm not able to test this.
