Software Update 2.39.44 (2024 Q4 Hotfix + new pool swim algo)

Александр Даниленко

@Artus-Diver that is really surprising that your other suunto watch could perfectly recognize styles.

For me and for some other people suunto are really bad in this and always had been.

I mentioned this here:
https://forum.suunto.com/post/129066

In my case it is true for both 9PP and Race S.

Saying about new firmware. I have tried it only once by the moment in the swimming pool. Style detection still bad, but it seems there are changes. For example, previously if I kept high pace in breaststroke, the watch recognized it as freestyle. Now it seems recognized it correctly. But on the other hand all other styles - butter back, free - all of them the watch recognized as freestyle with a new firmware.

So at least for me style detection was bad and it is still bad, but differently.

Also I noticed that it takes now much longer time for the watch to calculate the time of the interval. Before it was usually within 5 sec. Now sometimes it felt like 20s.

But I still need to do more tests.

@pavel-samokha while I generally appreciate new firmware that fixes bugs and introduces new features, I kindly ask Suunto to respect my DND settings and not wake me up in the middle of the night at 2:15 to inform me about a new firmware that is available.

Would it be possible to do that? Thanks!

Another hint for future releases:
Please remember my exercise.options like “Auto stop” and “feeling” and all other settings that are always lost after a firmware update.
I really hate this. Thanks!

A nice way to say this PLEASE do not start the same topic in multiple threads!

I can confirm this long lag in showing interval times. It was strange because the data area on the data page had a shorter time when reaching the wall (perhaps from the previous push-off), and then 5 to 10 seconds later it updated to the final time.

Regarding style detection. This seems to be a hard nut to crack to encompass us all… I learnt them in the early 1970s and know that they were quite different from e.g. Johnny Weissmuller’s in the 1920s (yeah, that Tarzan!). Looking at the club swimmers today there are also a few differences, and then comes the ordinary swimstyles handed down from parents, schools or public courses. Possibly we even have National differences - though competition tends to quickly streamline the styles down to what, for the times, are regarded as most efficient.

For me and my style though, this FW was a real success (on a Race S, making sure the Compass is calibrated before the activity since I suspect it is involved - and auto calibration did not work even when e.g. running for an hour). Last night I did freestyle, breaststroke and backstroke. All styles with and without hand paddles, with and without a Pull Buoy. I even did breaststroke with hand paddles and the legs tied down by a rubber band; imagine the quick, tight stroke needed for me to stay afloat and moving forward. And it still was detected as breaststroke! Perhaps the most surprising was a sloppy backstroke trial with both hand paddles and the Pull Buoy. I flailed all over the place (it felt like). No problems. Identified. As was normal unencumbered backstroke lengths.

Tonight I will try a bit of butterfly, even though I’m old and afraid of injury. Perhaps 100 metres medley, to keep it safe…

Edit: Today the Compass got auto-calibrated after the one hour running activity. I am positive that it didn’t work with the previous firmware (I switch the watch off after every workout - unless I have more than one during the day - so have to update basics every time; Time of Day, Altitude and Compass).

@Artus-Diver sorry for your experience, could you share this workout me to DM?

Artus Diver

@pavel-samokha

Yes, of course.
Is DM Diving Manager?
I have my last exercises (4 exercises) saved only in SuuntoApp and they are swimming in a pool (25m).

I am sending 4 files (*.fit) from swimming on the new software attached.

The files are marked as described earlier.

I would like to mention that my friends who are swimmers also have the same problems.
They say that it is impossible to train with this new software and I agree with that.

Best regards.

@Artus-Diver DM stands for Direct Message here, but doesn’t matter - thanks for sharing, the issue is under investigation

Of course “direct message”, sorry.

@Artus-Diver I am also having serious accuracy issues with the new update.

Previously the distance was spot on. Now I’m seeing serious underestimates.

For example yesterday I swam 1040m breast-stroke in 20m pool and the watch estimated only 700m. Today I swam 1240m breast-stroke in the same pool and the estimated distance was even lower. Before the update, in the same pool, swimming breast-stroke over the same distances, the watch was perfectly tracking the lengths.

I set the pool distance correctly and I’ve restarted the watch, but no difference.

And does the watch also have a problem with recognizing swimming style?
Because I didn’t have that problem before…

pavel.samokha

@Artus-Diver Could you also send logs?

Hmm, I alway swim breast-stroke, so never checked before…

Before update: it seems to have recognised my style as “Free”
Since update: it is now recognising “Breast”

It would be nice if it could do both, but I’d take distance accuracy over stroke style accuracy every time if it has to be one or the other…

No, the watch couldn’t handle 100 metres medley. It got so confused that all four lengths were seen as freestyle and it chopped up the interval in one 25 metres part and the other 75 metres. Furthermore, the interval time never got started, showed dashes “–” until I began the next interval. Medley begins with butterfly, so there lies the confused starting point. I also ended the whole session with 2x25 metres butterfly, which were called freestyle. Granted, my butterly style is not among the best, and is further degraded by an old man’s muscle loss.

Devis

Hello,
I have a Race S and just updated it to the latest firmware 2.39.44.
It now seriously underestimates the swimming distance (or the pool laps) and it fails to recognize all swimming styles.

Yesterday I swam 1000m (freestyle, backstroke and breaststroke) in a 25m pool, but the watch estimated a distance of only 800m.
With the previous firmware, the watch was tracking the distance (or the pool laps) almost correctly, in my case it usually overestimated by about +7%.

Yesterday it failed to recognize the backstroke (but this is less important to me).

Thanks, kind regards.

@Brad_Olwin sure, Brad! The problem is that if somebody wakes me up in the middle of the night for the second time, I tend to lose my temper easily. Would you be nice and gentle if somebody rings at your door in the middle of the night for no reason?

You asked this in the other thread that you locked:
No, I did not defer anything, or have any strange setting or whatsoever.
The last two updates (December and now February) did the same thing: during my sleep and DND enabled just like every night, the screen turned up, bright and shiny and woke me up.

It stated “There is a firmware update available. Install now?”

I can assure you, if this is a known bug, no it’s not fixed.

Btw: I reported this in December as well…

nhojb

@Devis exactly the same for me. Distance accuracy was previously very good. Now it is underestimating my swim distance by 20% or so, making it pretty much useless

Jussi Vaihia

Sleep tracking broke on Race after update. On the night of the auto-update no sleep recorded, then on following nights it records me falling asleep at 04ish losing half of my sleep.

GiPFELKiND

@Jussi-Vaihia oh nooooooo again? Sorry to hear this bad thing. Make a downgrade to previous Firmware and NEVER update it again
