      I’m seeing random heart rate spiking when using my Coros HR armband
      What can I do to resolve this? Or is this a bug with the Bluetooth connections for the Run Watch?

        This is not an issue with Coros, but an issue with the Suunto run (I have the same issue with a Polar hr sensor). They admitted it when I emailed support and said they’ll look into it (that was a couple of months ago),

          I have a Coros armband and a Coospo belt. I’m going to test whether I also have HR spikes.

            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.
