Suunto HR Chest Strap stopped work.

@edit

Right now I just started exercise, my chest strap is laying in drawer and I got something like this! Strap connected icon, and it shows and sits on 45 HR all the time!
Strap is not on my body and even its not wet.
Oh and one more thing I’ve noticed. When I successfully connected new strap with brand new battery It showed 100% battery. Right now it shows 40% (after few hours)

Right now I gonna unpair Chest Strap to be able use wrist OHR.

Bonjour,
j’ai ma Suunto race S depuis environ 1 an.
Depuis a peu près 2 mois, mes 2 ceintures cardiaque ne fonctionne plus (polar H9 et la Suunto neuve).
Je suis déçu parce qu’avant tout fonctionnait très bien.
Maintenant je m’entraîne avec le cardio de la montre. Donc les relevés cardiaque ne sont quasiment pas exploitables.
J’attend la nouvelle mise à jour en espérant que ça remette tout bien.

Avez-vous constaté des symptômes similaires ? Le problème vient donc du logiciel et non de la montre elle-même ?

Avec ma polar H9, la montre se connecte puis se déconnecte de façon continue dans l’écran d’accueil de l’activité. Et ça ne marche pas une fois l’activité lancée.
Avec la ceinture Suunto, la ceinture se connecte quelques secondes puis se déconnecte pendant l’activité de façon régulière. Les phase de déconnexion sont assez longues.

Edit : je pense qu’il s’agit d’un problème logiciel

Hello Tami999,

had the same problem some days ago. Solved it in the following description (Sorry for the german screens). After choosing the chest-strab in the menu of the watch, it worked.

I got Chest Strap selected here already.

@Tami999 I have the same issue since the update when this new Bluetooth device management has been introduced. I had two straps connected and the watch had issues to connect to the right one. Only solution was to remove one and use just one at a time and whenever I start an exercise and the watch doesn’t show that the strap is connected (even though it is) I discard the exercise (go out of the Start page to “home page”) and start the exercise again - then the watch finally displays that the strap is connected. Sometimes I have to repeat the process multiple times to connect to the HR strap. It is frustrating and obviously a bug for a longer time now.

@OutdoorMan Thank You. I got only one strap, and it worked since I bought Race2 when it’s aired. Never had a problem until this week. Also havent seen any update last time so I wasn’t sure I somehow triggered bug myself or sensor is broken. Good to know.

I’ve also several strange things happening with that on my Race1. E.g. the HRM doesn’t connect in “Trail Running” but does immediately in “Running”. (yes I selected it the way it was presented in the pictures, it just didn’t connect).
This was repeatable several time in a row: Trail Running - no connection to HRM possible. Back to activity-selection, select “Running” and immediate connection. Back to Trail Running: no connection. You get the idea…

Next day, next adventure:
This time I managed that the HRM and my Stryd connected in Trail Running but guess what: GPS was missing
Retried 3 times, always the same result. Again it worked in Running-mode and so I went with that mode because it was -7C and I was quite annoyed to debug my watch standing in the cold.

I now really hope for a fixed firmware asap. This are only the issues before the start of the activity, the “fun” continues during the runs. Not every time but often enough that I consider the watch to be unreliable in its current state.

TL;DR before your spend any additional $ for new batteries etc. I’d wait until the new firmware is out and they hopefully found the root-cause.

@Tami999 I have similar issues from time to time. Sometimes it gets stuck trying to connect to the built-in OHR sensor even though it tells me that it has connected to the external sensor - the way I can tell is that the sensor icon is different between the OHR and the external sensor. And sometimes it completely fails to connect to the external sensor no matter what, and I have to unpair the sensor and pair it again, and that sometimes takes a few attempts like you described. The whole experience is sub-par! And if I try to use two external sensors - that works even worse!

Quick update. I somehow connected Brand new strap (with 1 YO sensor) with my Race 2. I used brand new batteries i bought with brand new Suunto Chest Strap (without sensor) from amazon. With brand new battery, my strap connected to watch. I run 1h. Next day my race2 shows that my Suunto Chest Strap shows 30% batttery! I did run, everything was fine. Next day, I couldnt pair my Race2 with Suunto Chest Strap. I took another one battery from pack (5 batteries) (brand new). Connected 100% battery status. Next day it was 40% battery left after another +/- 1h run. I took off sensor from strap, I thought maybe it takes energy when not used or something (but anyway battery should last 500h) and next day when wanted to start run battery level of strap was 30%.

A: I bought fault batteries? But I used different brand before and problem was same. I THINK ITS NOT A PROBLEM + some other people got problem with Bluetooth on Suunto watches.
B: Sensor is fault or something, or draining battery so fast ???
C : I got problem with strap since like 2 last updates. Maybe its not sensor/battery fault but software?

I think there are still severe software issues… have similar problems with Suunto belt and SV1 und SV2

Same here. Haven’t had any single problem since I bought my ambit 3 peak + belt and sensor in 2014. Since the Q3 update I have had constant problems with my V1 and Suunto belt. I even bought a brand new belt + sensor because I thought the sensor was the problem but still getting random connection problems during activity.
65€ poorer and still having issues

Thank You so much for info! Iam getting sure, its not my Suunto Chest Strap problem but software. “At least” Watch HRV itself getting better.

After days of using Race 2 HRV i decided to give a try to Suunto Chest Strap again.

Yesterday on shopping i bought new CR2025 batteries different brand (Energizer)

I put new battery to strap.
Wet electrodes of strap.
Connected strap with Race 2 succesfully + get strap on my chest.
100% Chest strap battery.
I DIDNT start exercise. I just took off chest strap + I took off sensor from belt, everything was laying separate.
Next day I started exercise with strap - it was magically 20% batttery left before I started to run. Lost 80% during 24h without using it and having sensor taken off from belt with dry strap so its impossible it could work anyway + battery should last 500h.
Next day I started running exercise with 20% battery in sensor, ended up and magically Race2 shows it got 30% battery left
Did 40 minutes gym session - still 30% battery.

Now i know its not batteries fault. Its sensor from strap/Race2 software that reads wrong battery status or problems with connecting BT. or watch itself.

Its my probably last try and post, just wanted to give a info
