End of GPS trace missing

[Peter Tönz]

@Cédric-Dodrimont Same adventure and issue here!!!

Finished the Eiger E250 and my recording stops at the ascent to the grimsel:

https://maps.suunto.com/move/petertnz/64b2ac79dba57647cb258b96

The cumulated values (distance incl sleeping/bad gps reception, altutude…) are correct but the map is not complete. Its the first time I recorde such a long ultra trail in one piece. Normally, I stopped and synched on every live base to prevnet such problems!

I have used a Sunnto 9 Baro for this activity

Btw: I didn’t know, suunto has also a web-view of the activities. Looks nice!

@Peter-Tönz
You can also (manually) change the url like this, it gives another kind od display
https://app.suunto.com/move/petertnz/64b2ac79dba57647cb258b96/

Btw, are you both able to export fit file for these activities and see what is inside?

If one of you has an Android phone, take a look at this advice here
You may see raw data of your activities and check if they are complete (track, etc…) (not just correct summaries)

It looks like you guys are more responsible and more qualified to test Suunto products, I hope you can be the future suunto testers.

Very appreciated that you pointed out the issues.

That’s a typical tester what we have so far:

[Cédric Dodrimont]

@zhang965 Here it seems we have the same issue on S9B and Vertical.

@Peter-Tönz My Eiger teammate had a S9B, and the recording stopped just before Grosse Scheideg.

But it stopped earlier on the Vertical than the S9B, next time I will use my S9B

[Łukasz Szmigiel]

@Cédric-Dodrimont I wonder if there’s some legacy code in Vertical related to this issue if it’s the same in 9B.

What’s the JSON and / or GPX size for those workouts?

Yep, guess what, the person in my screenshot tested S9 as well.

Did you try with your ambit2?

[Cédric Dodrimont]

@zhang965 I had exactly the same issue in 2016 with my ambit during UTMB TDS.

I can understand there’s a limit for recording activities, but I would like to have an estimation on the activity duration we can record, or at least a warning telling me it’s time to stop the activity, sync the watch and start a new one.

[Cédric Dodrimont]

@Łukasz-Szmigiel The exported fit file is 3,8MB

[stromdiddily]

@Cédric-Dodrimont if the watches (all three of them) are showing correct stats (distance, time, elevation, etc) seems more like an issue with the app doesn’t it?

[Cédric Dodrimont]

@stromdiddily Maybe yes.
Or the watches stopped recording GPS data at some point, but no info on the maximum time we can record data with the watch.

[isazi]

@Cédric-Dodrimont rule of thumb is at least the battery duration, so a S9B in performance mode could have problem recording an 80 hours activity, but the Vertical should be able to do that.

Sorry to hijack, but I don’t understand how can that be done, from this table the log capacity of the ambit 3 is always bigger than battery life
watchuseek:

Or it when it doesn’t have the capacity to delete old activities when the log of current one is getting bigger?

[Mff73]

@André-Faria
maybe with charging during activity

[Cédric Dodrimont]

@isazi Thanks for your feedback, anything I can do to analyze what happened ?
The Vertical was configured in performance mode with OHR turned on. Recording stopped after 50 hours.

[Mff73]

@Cédric-Dodrimont
Did you export the fit file for this activity and checked it (for example with https://www.fitfileviewer.com/ ) and see if, by any chance, exported activity contains full track points (meaning data are well stored somewhere at Suunto, but not fully displayed in app) ?

If you have an Android phone, and will little geek skills ( instructions here ) you can try to find the raw data file for this activity, and be able also to check if, data send by watch to app, at that time, was complete.

[Peter Tönz]

@Mff73 I checked the file samples.json from the suunto app. And in this file, the last sample has the timestamp of the ending track. Also the distance for this sample is valid.
There is also no problem with the app. It seems the watch has stoppt recording the track!
Except the summary values, showed on the display, are recorded until the end.
I would expect a warning from a (not cheap) watch, when the memory goes out!

[Mff73]

@Peter-Tönz
Not nice

[Peter Tönz]

@Mff73 I use always the best GPS Quality (no data are better than unusable data ) and therefore, every one second a trackpoint is stored.
Is it possible to use the best possible GPS quality but onls every 10 seconds or so?
Thats enough for such long adventures and extends the possible ‘track-time’ by the factor 10!
(I mean that option was available for the Ambit 3 Baro)

@Peter-Tönz
I recall GPS was the only system available of all GNSS systems with Ambit and battery life “best, good, ok” was controlled by sample rate 1sec, 5sec or 60sec.
I have recently tried ultra mode and was very surprised about precision. honestly never tried it before. maybe give this a try? … don’t wait until the next Eiger Ultra

by the way: congrats to all you Eiger Ultra runners! awesome effort! I admire your running capabilities!!

[Łukasz Szmigiel]

@freeheeler all GNSS modes in 9PP and Vertical have a 1s fix except for tour mode, which won’t be useful for a run.
