Forerunner 245 Music + HRM-Run heart rate dropouts - This is the reason

Hi,

I have the same problem as many others. The HRM Run has not been measuring heart rate correctly for months. For this reason, I looked for many different solutions: I tightened the belt, changed the battery, even changed the belt. Nothing helped.

For this reason, it had to be the watch and not the belt. As a last attempt, I have now turned off the vibration and warning alert for each automatic lap. After the next training session, I found that the watch was measuring correctly. There were no dropouts anymore. After that I had to find out which of both functions is making troubles. So I did the following analysis:

Setup: Forerunner 245 Music + HRM-Run, Running without vibration and warning alert for each auto lap.

Setup: Forerunner 245 Music + HRM-Run, Running with vibration and warning alert for each auto lap.

Setup: Forerunner 245 Music + HRM-Run, Running without vibration and with warning alert for each auto lap.

Setup: Forerunner 245 Music + HRM-Run, Running with vibration and without warning alert for each auto lap.

As a result of the analysis I have to say that the warning alert for each auto lap or next round is the reason for the drop outs while measureing the hearth rate with the HRM RUN.

So @Garmin, please give us a patch. It is not really a solution to run without warning alert. It is an essential feature.

Firmware 4.40, ANT/BLE/BT 5.04, Sensor HUB 3.20

Okay, it is not only the vibration. Today, I had the vibration off and turned the warning alert during activity back on for any auto lap. The drop outs came back. For this reason I think both has to be turned off.

Setup: Forerunner 245 Music + HRM-Run, Running without vibration and with warning alert for each auto lap.

Tomorrow I will test the last combination: with vibration and without warning alert.

Try switching off wrist heart rate monitor for the run leaving alerts and vibration on.

Same issue here with firmware 6.20. Things are clearly not fixed.

I have the same issue with Music version.

Is it only the Music version or the non-music as well?

My wife has the non-music version, she says no such issues, stable HRM connection and signal with lap alerts on.

Today I made a test, switched off alerts (sound, vibration), it was stable.

Yesterday I had both functions on, that's when I found this forum :( (see screenshot)

I am new to Garmin, what is expected, will it be solved, or we have to use this watch as such?

Anybody having any news on this topic?

I've had a couple of times contact with Garmin support. They keep telling me it's caused by static electricity, which obviously is not. (And even if it is static electricity, they should fix it. Polar is capable to do it.)

Conclusion: Garmin is tired of people complaining about the same issues over and over again, and in stead of fixing the problem they're ignoring it.

Conclusion 2: I've paid 350€ for something that for a bunch of features that don't work.
