S9 (2.4.14) 'Calibrate FusedTrack' interface problem. Suunto Case #01853829

[kolyany4]

@Dimitrios-Kanellopoulos
It seems this is a (at least one of) reason of numerous complaints about messed track distance.

Today I did calibration before run at open space near starting line and all the same stuff I did earlier (awaited GPS and WHR lock, hit Start, explicitly locked buttons).

This time I payed closed attention to watch status during run.

And I was shocked seeing ‘Calibrate FusedTrack’ message in less than 2 minutes I’ve started to run.
Further, during run I saw that message very often in a places where no source of electrical influence could exists (in a park).
Sometimes that message changed to ‘Calibration successful’ following lap times screen and so on, but very soon ‘Calibrate FusedTrack’ message kept showing again.

As a result instead of 5.1 km

I got only 2.78 km

By the finish line watch showed that it has calibrated itself and I was able to finish Exercise in common way. However, according to SA tracking is stopped in the middle of the run.

Please, note, that running time is quite similar, showing that watch didn’t hang, but failed to track.

And here’re my questions:

1. Do I understand correctly, that if during run we get ‘Calibrate FusedTrack’ message, then corresponding distance (when such message been shown on a watch) could be excluded from track distance?

2. Is there some maximal distance/duration between tracking points (at which calibration should be ok), that is used as a limitation which FusedTrack can not exceed in order to restore proper track? Presence of such limitation could explain why FusedTrack fails to track entire distance. However, is such behavior considered to be ok by design or it is a bug?

[Dimitrios Kanellopoulos]

To be honest I never get a second time prompt to calibrate the FusedTrack.
This is very strange to be honest.

Did support reply? I am starting to suspect HW

Nope, no reply.
Neither to #01853829 nor #01850625.

It feels like those e-mails gone to /dev/null with previously assigned Case number and standard reply about being busy (Due to a high number of e-mails received from our customers, we need more time than usual to get back to you. Your case is in our queue and will be answered and taken care of as soon as possible) to calm down sender/customer …

I am starting to suspect HW

How one can make sure that HW is a problem? Is there any way one can retrieve data from HW sensors to identify its faultness?

[Dimitrios Kanellopoulos]

@kolyany4 Hmmm. What I would do is not to use the fused track and keep the navigation screen on. That screen also requires the compass to be calibrated. So it should expose the same behavior. Then we can wipe out a potential SW bug (if that also happens with normal navigation).

But hey I am no expert, but just a tester and doing my best to guess and help.

Will it suffice if I’ll do that using Walking Exercise?
What I should pay attention to during such test (with GPS==Best, NavScreen(e.g. Breadcrumb)==On)?

But hey I am no expert, but just a tester and doing my best to guess and help.

No worries!
I just wondered, whether you have secret kung-fu you can share with ordinary user to ease locate/eliminate the problem…

[Dimitrios Kanellopoulos]

Yeah walking is even better.

The navigation (breadcrumbs) screen uses the compass when you are static. Else it uses the bearing.

So I would:

Walk a bit, stop and check if it asks for compass calibration.

Repeat the above a couple of times. Compass calibration should be asked only once.

[kolyany4]

Ok.
Gone to make that test…

[kolyany4]

@Dimitrios-Kanellopoulos
Calibrated compass before walking.
Set Battery mode = Performance.
During walk it showed navigation breadcramp ok.
But, once I stopped longer than 10 seconds watch asked for compass calibration.

After about 30 minutes of such walking I’ve stopped exercise and went directly to General->Navigation->Compass.

While staying I’ve calibrated compass several times and tried to use compass (while not moving). Calibration tooks about 30-60 moves which is strange, though I was in a park (surrounded by trees).

Compass screen appeared a couple of times for a few seconds, and then screen with “Calibrate compass” appears permanently again.

My questions are:

1. Does internal compass require open sky view (by some reason) to calibrate?
2. How one can check what data has been stored as a result of calibration?
3. Should compass work inside appartment (even with errors caused by some electromagnetic emmiters)?

[Dimitrios Kanellopoulos]

In my experience I dont have to calibrate compass more than once when walking or using it.

I tend to feel its a hardware issue.

1. No compass can be calibrated indoors etc. It just might not work so great depending to metals etc.
2. I dont know if that is possible.
3. Yes

[kolyany4]

@Dimitrios-Kanellopoulos

How one can understand why watch keep asking to calibrate compass each time General->Navigation->Compass is entered?

Would there be any suggestions to solve this issue except reflashing of the watch?

What proof I can give to my local dealer that there’s HW problem in order to initiate guarantee change of the watch?

[Dimitrios Kanellopoulos]

Hmmm. There is no way yo figure that out except what other users experience.

I just tried it out, I had not calibrated the compass since 2 days and it did not ask me now.

Perhaps do a drag and drop on the fw to the suuntolink.

Find the fw file in the suunto link folder then drag and drop it to suuntolink. That should flash the fw without wipe of data. The fw file should be something like Ibiza
Zip

[Dimitrios Kanellopoulos]

You can ask for repair or replacement directly with suunto.

If you have tried all reset options that is the last way to go.

In this case open the request and I can help perhaps. But let’s first reach this point.

[kolyany4]

@Dimitrios-Kanellopoulos

Just reflashed according to your instruction (saw v.2.4.14 -> v 2.4.14.1170 during reflash).
Recalibrated compass.

Now when I enter General->Navigation->Compass watch does not requires me to do calibration.
Seems, problem with constant ‘Compass recalibration’ is solved.

Perhaps, problem with faulty tracks will go away as well - I will check that during next few days.

Thanks a lot!

PS. Perhaps, this trick regarding compass calibration and working steadily (without persistent recalibration request when entering General->Navigation->Compass) should be placed into the FAQ (as a prerequisitive for correct work of FusedTrack) …

[Dimitrios Kanellopoulos]

@kolyany4 yeah. I opened a bug about this. Let’s see.

Keep me posted please about the outcome of this.

@kolyany4 replying to your off topic. If you turn off sleep tracking and 24/7 HR monitoring and have 1h or 2h exercise per day on Performance mode the battery will last a long time between charges.

Thanks for hint, but I need 24/7 WHR & sleep tracking.
Otherwise (if I wouldn’t need WHR), I’d take entirely another product.

btw, actual off-topic was related to missing information about MIL-STD-810G compliance of S9 Baro.

[Brad_Olwin]

@kolyany4 The 24/7 HR and Sleep Tracking are the biggest hits on my battery. So if you need them I guess your are stuck. Personally, I would like to see the Sleep and HR used for recovery and health, I am not interested in just tracking. I can concur with @Dimitrios-Kanellopoulos as my FusedTrack does not reapeatedly ask for calibration. If I switch from Performance to either Endurance or Ultra during a run, i will be asked for a calibration but only once. Hope you get it resolved.

[kolyany4]

@Dimitrios-Kanellopoulos
Here’s intermediate follow-up.

Today during morning run I’ve encountered both the same initial problem as earlier (constant ‘FusedTrack calibration’ message) and ‘compass calibration’ message as soon as I enter General->Navigation->Compass.
Tried to calibrate both compass and FusedTrack several times during run, but it didn’t helped.

As soon as I’ve returned home I calibrated compass again, but strangely watch compass constantly pointed to the North wrong (in opposite direction).
I explicitly checked temperature that watch showed, at it was 14 degrees of Celsius at that time.

Lately, at the evening I’ve entered General->Navigation->Compass and watch both did not asked again for ‘compass calibration’ and pointed to the North correctly. At that moment watch showed temperature about 28 degrees of Celsius.

And here is my question:
Is there any problem expected with compass functionality in low temperature conditions (about 0 degrees of Celsius)?

[Dimitrios Kanellopoulos]

I dont know to be honest

[Brad_Olwin]

@kolyany4 I use my watch for SkiMo this time of year in low temps and no issues with compass. I will know more this weekend as well.
