S9B keeps forgetting Verity Sense/H10

wmichi

Hello, I have a S9 Baro, Polar Verity Sense and Polar H10. My watch always forgets the paired HR sensor after every training session. This is my “workflow”:

I pair the the Verity Sense
I start a training session using the paired Verity Sense and do my thing (all works fine, no issues)
Finish training and sync the watch
I start another training session -> Verity Sense can not be found, although it is the last used HR sensor
So I pair the Verity Sense again
I start a training session using the paired Verity Sense and do my thing (again everything works fine)
Finish ans sync the watch
Guess what comes now… the watch forgot the paired sensor

I think I have paired my Verity Sense hundreds of times because the watch always forgets this sensor. And it’s the same with the H10.

I have disabled all goodies on the Polar sensors (ANT+, multiple BLE connections) and they are definitely not connected to anything else (no other watch, no smartphone). The sensors have the latest firmware installed (also the S9)

I had the exact same issue with the Suunto 9 Peak (which I have sold). With Garmin and Polar watches everything works fine. So it seems to be a Suunto issue. Has anyone similar experience and maybe a solution?

@wmichi I feel your pain. VERY annoying.

@wmichi don’t have those sensors, but everything worked fine with a decathlon HR strap, so is the suunto one. Maybe it somehow depends on the sensor itself?

@wmichi
I’ve had the issue with my S9B, too, but only once.
I’m not sure if it is a watch or a sensor issue? I’ll check if syncing to polar (by laptop and phone) could worsen the situation.
If I notice it happening again with my watch, I’ll let you know.

wmichi

Thanks for your feedback everyone. I am sorry to hear that I am not the only one.

@freeheeler As far as I can tell, this does not make any difference. It also makes no difference, If I activate the multiple BLE connections of those sensors and use both my Polar and the Suunto watch.

Maybe Suunto should think about the sensor management and make it a little bit less ~~crappy~~ cumbersome.

@wmichi My Verity Sense works great with my S9 without any such issue

@wmichi
I’m not sure if it is a Suunto issue, as my previous Suunto chest belt connected without any issues

@wmichi
Did you try a soft reset ? Maybe there’s just something stuck.

pilleus

S9B and Verity Sense/H10 and no problems until now.

wmichi

I tried soft resets and factory resets on the Baro and the Peak without success. Maybe only newer devices are affected? I have the Suunto 9 Baro Granite Blue Titanium… Or the problem is not the watch but the sensor(s). I don’t know. I will contact support.

@wmichi
are you 100% sure these sensors are not paired with something else which stole the connection after each activity ?

Mitch9

For me the combination S9B and Polar H10 works without connection problems.

wmichi

@mff73 Yes, 100% sure.

I went into the basement out of reach of every other bluetooth device and tried to switch back and forth between the sport selection screen and the screen that follows (where you wait for gps signal and actually start the activity). Out of 10 tries, 8 times the watch could not connect to the paired Verity Sense. It worked 2 times

The same with H10: 7 out of 10 without success.

So it does work sometimes.

@wmichi This is very strange, I’m using my Polar OH1 wilth my S9B without any problem for nearly two years. It has never failed me, not once, and I use it at least 4 times per week. The same before with my Polar H10.

Could be an issue with the watch Bluetooth module? Yes, but if you had the same problem with the S9P I guess we are looking for an external issue here, would be very strange that both watches have the same issue.

What I would do is Check if I’m in the latest firmware with the sensors and softreset the watch, if the issue persists I would do a watch hard reset, and if it still continues failing I would contact support.

@wmichi I am terribly sorry for this stupid trivial question, but someone had to ask: What is your real workflow? Because, according to my experience, Verity Sense takes like 10-20 seconds to initialize. Aren’t you just too fast? I put my verity sense on, I turn it on, then I wait like 20 seconds and only after that I go to “Excercise” in my watch. If you select “Excercise” before the sensor is fully on, watch won’t find it… The same is valid for H10. First you put it on and make sure electrodes are wet, then you wait couple of seconds and then you enter the excercise menu. Perhaps other watches search for sensors continuously, but Suunto 9 seems to check for HR sensor only once (when you enter “Excercise”).

And for that workflow you described originally: does it also happen when you start second exercise immediately after you finish the first one? Or does it happen only when you do the second exercise another day or such?

wmichi

@inkognito That’s no stupid question And maybe this could be the reason, good point. I don’t think I am too fast with going into exercise mode, but I will try to slow down

From what I know it takes time to lock to a device that does not provide accurate readings or has a good signal.

I know you can reset the h10 via using the battery vice versa (check polar website ) , try that and try using a new battery. Make sure the battery is not expired.

If that is still happening , let’s check the logs.

I asked about the h10 because there I am sure there is no problem.

wmichi

@dimitrios-kanellopoulos I tried today what @inkognito suggested. I put the Verity Sense on my arm, turned it on, waited a minimum of 20s and then went to “Excercise” and selected my sport profile -> Verity Sense connected. I did this a couple of times, and it worked every single time.

It’s like @inkognito said: the S9 doesn’t seem to check for paired Sensors continuously, and if the Sensor is not ready, the S9 never finds it. I guess it’s the same with the H10 (haven’t tried it yet).

Thanks @inkognito

@Agustin-Gonzalez-Perez-Corral Maybe this works for you too?

freeheeler

@wmichi
I observed that it must be the other way around, that the sensors take some time before they are ready. S9B shows the HR belt signs right away when there’s a sensor available… but anyway, it’s a detail and I might be wrong
happy to see that you could finally sort it out

@wmichi it might depend on the sensor. I used to use the Suunto HR belt and now I use the Wahoo HR and cadence sensors, and I find that if I start the exercise, even with the sensors not ready, eventually (after 20-30 s), they show up. This might be because some sensors stay “visible” for BT connection only for a limited time (30 - 60 s), and if they are not connected they stop being visible.
