Heart Rate “spikes” when pairing Coros HR armband with Run
-
Tested today with Coospo belt – seems fine to me : (just when starting up, but it might be because of the belt)
-
@zagazoo Is the firmware on your armband up to date?
-
Also having issues with the Coros Heart Rate Monitor armband with the Suunto Run.
Abnormally high spikes appear out of nowhere and certainly not in keeping with the effort/pace etc of the run. These spikes frequently jump up 20 beats in a second before falling just as quickly.
Sometimes almost the entirety of the run in terms of the heart rate graph will look fine apart from the end of the run when these spikes will just appear.
Given the fact others have reported the same with both the Coros and Polar heart rate armbands there is clearly an issue here.
Coros Heart Rate Monitor is on the latest most up-to-date firmware as is the Suunto Run.

@zagazoo I use Coros HR armband a lot with Race and Race S. I have never seen spikes like this. This may be a Run specific issue.
-
Tested today with the Coros HR armband, everything seems fine - firmware du Coros : V1.22.0
-
Today I ran with the Suunto Run and Coros HRM together and with my Garmin paired with a Coospo chest strap.
The graphs look very similar with some very slight differences as to be expected comparing optical with a chest strap but again the Suunto Run with the Coros HRM produced a spike not present on the other combination.
It showed a brief spike elevating my heart rate by around 20 BPM.
Tomorrow I’m going to replicate the run but with the heart rate monitors switched to see what is going on. I’ll provide some pictures after to show the issues I’ve had.
I have also noticed that even when using a chest strap with the Suunto Run that the heart rate graph on the app and the summary values provided for Max Heart Rate are not always the same. The graph might show a max heart rate around 174 for example but the information provided in the Heart rate section along with the Physiology and Power may provide a max HR of 190.

@ruNSuunto I cannot find the peaks with the same type of equipment as you.
Can you check the firmware numbers of your equipment: Suunto Run and Coros Heart Rate Monitor? -
@zagazoo for spikes problem with external HR sensor ( chest or optical band ), solved twice by re installing the app.
I got that problem one year ago, suunto race, and once again a month ago, vertical 2
Suunto support explained to me there are different heart rate algorithm which took place, once before start activity ( when external device is detected and read before the start), one during activity, showed on the screen, one to create the summary graph on the watch when activity ends, and also one when sync with the suunto app )
In my case the final on watch report was good, but spikes were noticable during activity ( data on screen ) and also on the app report.
Re installing the app solved the problem each time.
Strange isn’t it ?
Hope it will help

The smartphone app?

@Mff73 yes
strange isn’t it ? at first it seems a watch / bluetooth whatever problem with the external device, but in fact the app algo or watch / app link / algo are both implied in this bug
