Constantin: monitor effort drift against your session average

[Speed Man]

I’ve been using it every day lately, and I really like it. It helps me control my effort, pace, and HR variability extremely well.

[Łukasz Szmigiel]

@Speed-Man it’s great that it works for you! What watch are you using? Are you using it alongside other S+ apps or guides?

[Speed Man]

@Łukasz-Szmigiel I’m using the Race 2, and right now I only use the SuuntoPlus Constantin app. Earlier this month, I had an experience where the watch shut down while running three applications at the same time.

As for ZoneSense, I use it directly from the watch without opening the app. Using it this way, I feel the watch performs much better and runs more smoothly.

[Łukasz Szmigiel]

@Speed-Man thanks for the details! I’m getting reports that Constantin is either shutting down itself or other s+ apps if used alongside, like zonesense + constantin + aerobic decoupling.

I’ve made some redesign efforts to make the app lighter and I no longer see anything related to watch being overloaded, but I only have access to S9PP and Race S.

It’s kind of hard to debug the issues if one doesn’t have access to hardware

[Lazyjones]

@Łukasz-Szmigiel Today my Race S crushed. Only Constantin and Fat &Carbs counter were running.

[Łukasz Szmigiel]

@Lazyjones I’m working on a new version with split templates. Three templates instead of one. Let’s see if hardware will like it more.

[Łukasz Szmigiel]

The new version is in - 1.42 which should be easier on the UI processing. Happy testing!

[Speed Man]

@Łukasz-Szmigiel Your application is truly useful. I hope Suunto will support you on the hardware side as well — your work deserves to be integrated into the ecosystem.

Today my V2 crashed. Only running Constanin and a workout. When I tried to go through the pages the watch was fun until I hit the button again to go to Constanin. Rather than go to the page it froze for about 20 seconds followed by a restart.

Sorry I would love to use this, but crashing makes me sad. Nothing worse than crashing watches mid-workout.

[Łukasz Szmigiel]

@Stavrogin I’m sorry to hear that. The real issue is that I’m unable to debug this app on V2 as the only way to do so would be to have access to real hardware and logs and I only have S9PP and Race S. I suspect there’s something wrong in current V2 firmware as it doesn’t crash on older watches - or I haven’t experienced it yet.

What activity did you try it on? Did you have other features turned on like guides or routes.

[Stavrogin]

@Łukasz-Szmigiel Thanks for reaching out.
I was doing a Trail Run with a workout Guide on. Nothing else. No Routes. I had a Polar HRM attached.

To your point the HexHunter much the same thing. It was a crasher for me.

[Łukasz Szmigiel]

@Stavrogin thanks for extra info. A guide is de facto an S+ app. So you had Constantin + Guide (2 apps). But it shouldn’t crash the watch nevertheless. Suunto watches are pretty clever and if they see that there are no resources left, they will kill non essential apps, it’s hard to crash the watch and the latest version is simplified.

I’ll do some more digging into optimising the issue but the problem is that on S9PP when I’m using navigation and 2 S+ apps, current version doesn’t hit the limit. I’m surprised that the issues happen on V2 which is newer hardware.

Perhaps @suuntopartnerteam can shed some light on it?

But just to clarify - it didn’t crash at the beginning of the run but later, when you were cycling the screens, right?

[Stavrogin]

@Łukasz-Szmigiel That is correct. The freeze and reboot was triggered by cycling through screens. I feel like that was what happened with the HexHunter app as well.

[Łukasz Szmigiel]

@Stavrogin it seems to me that the UI is still too heavy and, perhaps, tries to do all the painting at once after the screen cycle. I’ll let you know after I release a new version with delayed rendering and we’ll see if it helps.

[Łukasz Szmigiel]

@Stavrogin new version should be available now in SA, you may want to give it a try. The code is ~25% smaller in general and there are some additional optimizations added to how the UI drawing is being handled. If that still crashes - I’m afraid I can’t do much without the support from Suunto or logs from V2 running the app

[Stavrogin]

@Łukasz-Szmigiel thanks and I will give it a try

[Bigb0zz]

@Stavrogin Did you enable or disable Always-On Display during activities?

[Elmiuel]

Hi everyone, I’ve also been testing Constantin because I’m interested in its setup. I have a V2 and initially started with 3 Suunto Guides (too many, several were faulty), then I switched to 2 Constantin guides and a 3rd grade training guide… also… the watch would freeze or the Constantin screen option would remain BLACK.
If you also use it in conjunction with ZoneSense, it also fails. I don’t think there’s compatibility yet with multiple systems (3 guides + activity and data watch) working outdoors… Suunto could refine these guide options, which are, in my opinion, quite interesting. Thanks, Luckas️

[Łukasz Szmigiel]

@Elmiuel thanks for your report. If you haven’t - check the current version (updated yesterday in the evening) - I’m getting reports that it’s more stable on V2.

When the particular SuuntoPlus app goes dark it means the watch unloaded it. You can confirm it by going to workout settings during the workout and checking active apps - the uploaded apps should be off.

[Stavrogin]

@Łukasz-Szmigiel I loaded it up and was able to start an activity. However when I hit the lap button Constantin disappeared the first time I tried. On the second attempt I was able to keep it on the screen. Looks like it might be fixed.
