Heart Rate Measurement stops
-
@Brad_Olwin
I hope it will be achieved soon, we all expect positive results from your great work. -
I am having the same problem. I’ve had to restart my watch to get the HR working. My problem - is that I do not have to option under Settings to revert back to the last update. Under Settings - General - I only have About, Software update, Time/Date, Language, Tones, Display, Power saving, Personal, Reset Settings, Power Off. I don’t have Data Privacy as an option. What can I do?

@michmccoy same here. Watch is 6 days old. This morning no record of sleep. Not through the day. I read a shutdown and restart of the watch fixes it. Can confirm it does. Assuming it will go for another 6 days and stop again.

SPP9: Has anyone already tested the update version 2.39.34.22544 with regard to the heart rate problems described above?
I would like to read your experiences first
-
since I bought the problem was persistent just one day per week. But know atfter the updated 2.39.20, is even worse, everyday I have to reset.
-
A fix now for this and working for me.

@claenn I just followed arkaitgavan’s instructions to change the software and I selected the 2.39.34. That was the only other option for software. The previous software was 2.39.20. I was having the same issues with the watch not measuring sleep and not measuring heartrate without a soft reset at least once per day. Fingers crossed. Stay tuned
-
Just to add, I am having the same issue of the optical HR sensor crashing with my Race S (2.39.20). 2.39.34 is not yet available for this watch. Thanks @arkaitzgalvan for the instructions on how to go back to the previous firmware as it didn’t happen before the update.

@Aynrnd , as said in the Suunto app the new version is a downgrade to a previous version of the software to fix a critical issue caused by the latest update. This software is practically the same version as 2.37.48.
If your 9PP was fine before, It should be fine now.
Good luck! -
@magbueno Great news! The 2.39.34 software update fixed my problem!

I had similar problem with with my 9PP running software version 2.48.16 and now after the upgrade to version 2.50.28 still: out of the blue the heart rate monitor LED lights stop working. Only after switching the watch off and on again, it reactivates. I want to track my sleep and HRV and the failure happens most often at night messing up the statistics.
Anyone knows a sustainable solution? Much appreciated.

I am running into the same issue on my suntoo 9pp with the 2.50.28 version :'-(
-
I also have the same issue. 9pp running 2.50.28 and many times over the last year or more wrist heart rate stops. Green leds not flashing. Turn off turn on to fix but you only realise it’s stopped when you synch in the morning.
Night sleep, recovery all inaccurate.
I have no good reason to buy Suunto again

Same problem as other recent users. Running 2.50.28 and HR monitor stops working. Can’t turn HR function off and back on, have to do a soft reset. The issue seems to have started (for me anyway) about a month ago, but has been increasing in frequency each week. I thought this was resolved way back in 2.39.20? It’s the same behavior at least.

Can’t turn HR function off and back on, have to do a soft reset.
By means of the control panel, you can try by switching on and then off the low power mode. I’ve tried this sometimes in the past and it worked.
-
@Matúš I tried it out as well, but unfortunately it doesn’t work for me…Soft reset is mandatory to have back the HR monitoring.
I’ve noticed that the HR lockout has been occurring more frequently recently.
Could it be the strap fastening? When it’s hot, I wear it looser, and that’s why I’m having doubts.
In light of this known issue, do you think the manufacturer will release a fix? It would be a real shame if it were abandoned…

When it’s hot, I wear it looser, and that’s why I’m having doubts.I’ve just tried and it seems that the optical sensor switches off at about 15-20mm from the skin, but I doubt that you are wearing the watch so loose, plus I think that the HR sampling is pretty unreliable in this condition.
-
@Matúš I just thought that perhaps the intermittent contact with the skin could cause the sensor to go haywire, causing the monitoring to block… but I’m not sure that’s a valid hypothesis…
-
@Matúš My hypothesis is that there are some extra features that do not really work well together.
Test 1: new battery installed because watch could not last for more than two days which is somewhat below specs. Before battery switch the sleep tracking was unstable, after the change it never came back.
Test 2: turned of heart-rate measurement completely since it is no use … Surprise it is still trying to ignite the measurement LEDs ???Restarted it several times, being more than a week since I received it back.
Multiple trainings done, they worked out OK and battery time seems to have improved since I can use the watch more than two days on a charge now.However it is entirely unlike the other Spartan Sport WHR I own which can be worn a week and still has 80% of battery power. Both have new battery but remarkably different performance, sleep recording broke something in the 9PP as far as I can deduce.
