[solved] Reboot during activities

[chargerunner]

@jjpaz I don’t have a lot of guides or apps, and only use Burner since the hard reset. They are the basic guides and apps that come with the watch, I haven’t added any new ones. I also have running / cycling activities every day, maybe it’s too much, but I don’t expect that the watch can’t handle such amount of data…

I have had this issue 4 times in 4 months (last one two days ago) but have anyone noticed that after such a reset watch has problem with fixing to the GPS? I noticed that every time after such a unexpected reset.

@bart80
the watch loses the AGPS file when crashing. this file is necessary for a quick satellite fix. if you sync your watch to SA it will load the file again and locking satellites will be as fast as usual

[bart80]

@freeheeler Good catch. On Saturday that happened just before the Race I was participating so had no time to go back for phone Next time I will check this. Nevertheless, logs send to Suunto.

@freeheeler @bart80 Mind that it might take several (up to 15) minutes for the old S9 to unwrap/process that newly synced AGPS data. So syncing and trying to start an exercise immediately after won’t probably help (tried that multiple times).

@chargerunner

After downgrading to software version 2.20.30 the issue is gone.
The current version was driving me crazy, 2 crashes on one training is´nt usable anymore.

[chargerunner]

@Reiner Glad to hear it @Reiner . How long has it been since you downgraded? I would wait at least one week before being a bit more sure about the issue not coming back After the hard reset (still not downgraded), my watch went on for one week without error before the crash came back…

[SimonHumm]

@chargerunner Same behaviour for me. Now every time I go for a run there’s the added excitement of “will it or won’t it work?” I think Suunto need to release a statement or an acknowledgment of the problem and give us some comfort that it will be fixed.

@SimonHumm That’s what I’m waiting on.

@inkognito - do you know if a soft reset will also flush the AGPS?

I had an issue with a Sports App properly starting ( blank screen or no data fields in the Sport App screen ) this morning. After two or three false training starts, I soft-reset the watch ( no phone sync ) and the next training started the Sports App correctly.

The only downside of the soft-reset is that GPS lock took more than 5 minutes, possibly 10 minutes. After all of that delay, I had no issues in the 3+ hour training ride.

@Bradleyd said in Reboot during activities:

yes it does

[isazi]

@SimonHumm I provided all logs to Suunto, and I would assume that the bug has been identified as more logs are not necessary. I have no idea what the bug is, as my watch never crashed.

[chargerunner]

@SimonHumm I also walk on thin ice every time I start a training too Have to constantly watch the watch during the first few minutes, if the watch survives this period, then I can continue the exercise with a calmer mind

I hope the issue is identified by Suunto now and a fix is released soon (if it’s a software issue). At my place it’s cold in the morning this period, it’s not funny to wait in the cold for the watch to catch GPS signals again after a crash

@chargerunner and others experiencing this frustration, it appears like there is an issue with GPS state and SuuntoPlus apps on my watch that is leading to the reboot on training start.

I spent a little bit of time playing around with different configurations on an S9 and landed on the following experiences with my Polar H10 HRM and a bluetooth CORE body temp sensor for the SuuntoPlus Sports App.

1. multiple successful exercises, including run and unspecified indoor, whenever I disabled GPS and used the Sports App.

2. two back-to-back crash followed by watch restart, when I tried a run training with good GPS. In both cases, no Summary data for the Sports App was written ( suggesting the app initialization didn’t complete ) and no HR data was shown on screen before crashing.

3. immediately after the 2nd crash, I turned off GPS and completed a 20 minute run successfully. After the run, I did a quick check to confirm that a GPS enabled training without a Sports App would start.

4. immediately after the successful run, I tried two back-to-back runs with GPS. The training started, but the Sports App screen data was empty ( – on the screen field ) and no summary data was written at the training end ( again, suggesting the app initialization failed ).

5. immediately after, I soft-reset the watch, waited 12 minutes for GPS to lock, and successfully completed a 20 minute run with good GPS and a Sports App.

In my case, the watch doesn’t have an AGPS file, so I have manually seeded location using the Navigation “Your Location” before starting a training. If the reboot during activities cause is state based, then either soft-restarting your watch before training -or- turning off GPS -or- not using Sports Apps may help with stability.

@Bradleyd
what GNSS combination do you and all you guys experiencing this issue use?
GPS only or a combo of GPS and others?
I’m using external HR always with S9B, and most of the time S+ climb, burner or zones. I’ve never had a crash with the latest firmware. I’m always using GPS and Galileo.
If it was GNSS related, maybe it’s worth a try to switch system combo or go for GPS only, over avoiding using S+ or soft-resetting and waiting 15min in the cold on a daily basis.

[inkognito]

@freeheeler I had crashes with GPS+Galileo and GPS+BeiDou. Didn’t try the other…
I had perfectly fine exercises with various SuuntoPlus apps without any crash, only to find it crashing next time with the same setup…
I also had crashes when I didn’t use SuuntoPlus at all…
I had crashes with external HR monitor and with watch OHR…

Instead of trying crazy things like rebooting the watch on daily basis or hoping that hard reset will save us (it does not), the best would be if someone from Suunto would tell us what their analysis showed Well and provide some fix asap…

[freeheeler]

@inkognito
Suunto does not communicate much, but as I understand @isazi 's statement they seem to be on it

[isazi]

Suunto sent us a message, we need some information from people having crashes, please contact me with a DM for more info. Thanks.

I had another reboot today… In fact, I went like “let’s combine many functions together and see if it crashes”

So I used:

• Sport mode: Walking - custom with ETE/ETA fields
• SuuntoPlus: Burner
• Navigation: Route
• I set target HR zone to Zone 1

Watch crashed and rebooted around 26 minutes after start… I was stationary at that moment (taking a photo with my phone), I looked at my watch and saw a black screen and then, several seconds later, the watchface…

But this made me realise one thing! This was not the first case my reboots happened like this. In fact, I had multiple crashes just after I stopped for a while! Usually due to photos, road crossings etc… I did not use pause or autopause…

I tried to replicate this immediately after with no luck… I went on for another 40 minutes with the same setup without any problem…

Anyone with similar experience (crash happened when you stopped for a while)?

[freeheeler]

@inkognito
I did groceries today and didn’t stop the activity when I was inside the building. navigation, hill climb, external HR etc… no crash at all. but I never had a crash with the latest firmware.
I recommend @isazi 's suggestion
