Is it expected that even an example app crashes the watch with a Syntax Error ?

After having my own app crash - and almost brick the watch or at least having it perform a fault recovery for a couple of minutes - I thought I reduce the app to a bare minimum and work from there but even that crashes the watch. I then copied the Dynamic Icons example but still get the crash log below:

Hi @Unpaired8373 ,

Does the watches JS-runtime support WASM by any chance?

Wasm is not available!

Is it expected that even an example app crashes the watch with a Syntax Error ? … I then copied the Dynamic Icons example but still get the crash log below

That is not expected behaviour I just now checked the Dynamic Icons example on both a Race 1 and a 9 Peak Pro. Neither crashed during an exercise. Best advice that comes to mind is to first make sure the watch is running the latest firmware.

Running JS inside an HTML template can be a bit finicky and seems to have the highest potential for crashes at present.

guys I need help, anyone know how to use the crown/middle button to scroll to the next ui?

We do not presently have a way to capture scrolling events, but as you found…

i find out if ur ui is big enough it will able to scroll down,dont have to do anything.

… the watch will automatically attempt to scroll elements with the crown

SuuntoPartnerTeam

@Thibault-B.

I think the issue is that I override the onClick action, so I should keep it empty if in pause. But I do not know how to do it.

One possible way is to use the uiViewSet in combination with userInput. Simple example:

<uiView>

  <div>
    <!-- The set allows toggling the capture of 'down' -->
    <uiViewSet id="test">
      <!-- First set element -->
      <div>
        <userInput>
          <!-- systemEvent prints into OUTPUT when running in the simulator -->
          <pushButton name="down" onClick="systemEvent('Hello world')"/>
        </userInput>
      </div>
      <!-- Second set element -->
      <div>
        <!-- Here nothing gets printed -->
      </div>
    </uiViewSet>

    <!-- Press 'up' to enable/disable the capture of 'down' -->
    <userInput>
      <pushButton name="up" onClick="next('#test')"/>
    </userInput>

  </div>

</uiView>

Edit. Just to add, you would probably then want onExercisePause() to do the toggling of the set

Thibault B.

@SuuntoPartnerTeam Nice! Thank you.
I toggle the capture in the onExercisePause, onExerciseStart, etc as you recommended in your edit.

@SuuntoPartnerTeam Thanks for the reply on a Sunday.

I am testing with a Race S if that makes a difference. The firmware is the most recent one according to the watch menu (v2.50.28). Also I ran the mountaineering activity (or what it is called in english language setting) with no GPS fix (ignore and continue when prompted).

This might have been overseen.
Any chance to get the proper resources for the baro trend?

Thank you!

said in [Question] No stupid questions - ask anything here:

@SuuntoPartnerTeam I am trying to display the baro trend in my S+ like the litte arrow that shows how the barometer is changing:

I used to have the icons for the 9 diffeent symbols like this:
{ "name": "trend", "source": "Fusion/Altitude/PressureTrend", "type": "subscribe" },

<eval input="{zapp_bottom_input}" outputFormat="keyValue 1=&#xF280;|2=&#xF281;|3=&#xF282;|4=&#xF283;|5=&#xF284;|6=&#xF285;|7=&#xF286;|8=&#xF287;|9=&#xF288;" />
Now something must have changed in the background and the icons don’t work anymore. Can you tell me the current output for this?

Thx!

@SuuntoPartnerTeam Hello, one question regarding the UI.
I am using templates but would like to have small portions of the UI visible depending on logic.
Is this possible?
My current approach: Having different templates. But with this approach I have a lot duplicate html code.

Thanks

Hello, I’m a the new one

Are there any plans or ways to listen music on my Vertical 2 without the phone?
I saw, that there where some watches where you could put offline music directly on the watch.

Garmin supports Spotify, will come something like this in the future? I’m not a big fan to carry my phone all the time with me, so it would be nice if there is a feature like that.

Greetings and thanks!

Hello guys I having trouble when I trying to screenshot my app on the simulator,when I press the camera icon, it show up the error.

[23:29:31] [error] Error loading HTML template 't.html': _0x26deff is not defined

Before I pressed it the app is running fine without any error .I even trying to create a new app with the default code and take a screenshot too ,but it come out the same error.

Hello, can anyone help, I am trying to display Graph for HearthRate.

I am using this code for displaying graph, it is taken from one of examples just modified input path for current hearth rate:
<graph style="position:absolute;
              left:0px; top:0px; width:100%; height:100%;
              box-sizing: border-box;
              padding-right:90px; padding-top:60px; padding-bottom:60px;
              font-size:21px;"
       valueFormat="HeartRate_Fourdigits"
       type="line"
       grid="three lines"
       inputType="subscribe"
       input="/Activity/Move/-1/HeartRate/Current"
       min="0.6666666667"
       max="3"
       slack="0.1"
/>
and it works fine in simulator and I see this:

but when I upload app to watch (Suunto 5 or Race 2), than there is no graph line for Heart Rate:

@suuntopartnerteam do you have any hint what can be wrong ? It works in simulator but not in watch, when i see system events i see only this error and not sure if it is related:

#1998533 25.03.2026 06:10:01 : ERR WBMAIN : *0: app 1248 Event 3 80523203

Hi, I have the same problem.
Running on a MacBook Air with newest OS.

@Strulian Hello

i was hoping to implement this myself, but the public available api from spotify does not allow to download anything - for obvious reasons.

I don’t think suunto today allows to store large data on the watch itself (although a race s already has 32gb free storage).

For Garmin, spotify made the app themselves. Perhaps Suunto can persuade spotify to make the app themselves.

But, another thing is lacking: we cannot link wireless earbuds with the Race S/2.

Hello @harry08 .

would like to have small portions of the UI visible depending on logic.

The uiViewSet element is exactly what you are looking for. It allows you to programmatically switch portions of a template without duplicating everything

Is anyone else having trouble taking screenshots?

This is an unfortunate bug in the latest release (as mentioned in our simulator post). No ETA on the fix, but the dev team is aware of this issue

Is there any way to restrict installation to certain devices via the manifest or somewhere else?

For example, my app is designed only for watches that support entering user settings, and I want to prevent it from being installed via the SuuntoPlus Store on devices that don’t support them (like the Suunto 9 Baro or non-PRO Peak models).

SuuntoPartnerTeam

@Egika Honestly, this is the first time our forum team has seen icons used in that way and we don’t know what could have changed to make your formatting (with an added <div class="f-ico"></div> around) only work in the simulator. You might just have to implement additional setText() logic in your code. The Dynamic Icons example may be of use.
