Suunto HR Belt unreliable with 9 Peak Pro since firmware update - anyone can confirm?
-
@Ecki-D Just out of interest, is it a must for you to use a Suunto chest strap? I only use H10 and no issues so far.
-
@Highlands nope, that’s another option to try if I can’t fix it.

I checked runs from Spring in this year.
In April, with apparently the same setup, the R-R data recorded by the 9 Peak Pro looked normal. The recent recording contains repeated missing or corrupted R-R intervals and implausible HRV values.So it doesn’t look like a Firmware thing cause the major BT updates happend in Sept 25 and in January 26

@Ecki-D.
I do happen to have the same issue. Used HR Belt today during a run. Started run and belt showed up as connected. Within the first 30sec no HR was shown on watch. Then after a couple of sec it automatically reconnects and watch shows HR. But, as in your case, numbers seem to be not correct and tend to get stuck.
Tried to disconnect and reconnect belt, new batteries but no change.Don’t know if I should do a factory reset on my watch just to see if that may solve the issue.

@Pyranya I used mine yesterday and it was fine. I will try again today and report back.

You’re using a 9 Peak Pro as well? What firmware you’re on? My watch is on firmware 2.50.28greez

Same firmware, it is the last available. I was doing some testing and I will repeat today and get back here on my results.

Also using a 9PP with the latest firmware and the original Suunto Smart HR Belt. I do not have (all?) those issues, sometimes it looses connection but the graphs look fine as far as I can tell. But I also will watch this and see if anything weird occurs.

@Pyranya Here is the example from my run, a 20 min walk today was fine as well. V2 and S9PP paired to SHRM2
Walk with Run 2 OHR and S9PP with SmartSensor, these don’t match as well as I would have expected.

@Ecki-D
I’m not sure, but you can see from the graph that there’s a regular drop in heart rate at that point. It seems to me that this happens every time the connection is lost.
During this run, I made sure to maintain a consistent pace throughout. The first 5 minutes and the last 5 minutes were slower than the 20 minutes in between.

@Pyranya have you checked the R-R plot of your heart rate data? The strap may be not working anymore, and that is not fixed by changing a battery.

@Pyranya it is not in Suunto App. Export your file to an external service, such as Runalyze or quantified-self.io and check it there. If it is very noisy, then there is some issue with your strap.
