Unstable connection with HRM Run

It seems like the connection interrupts and the 245M gets the data from my wirst until it reconnects again (during a run).

The HR drops from 150 bpm to 125 and then back to 150 for example. Anyone facing these issues as well?

During most of watch alerts (laps, training steps, etc.) my HRM-RUN is being disconnected for a while and drops to 75-76 bpm can be seen. Well known issue with the latest FW 4.40, yet with no response…

Correct, it should be an issue with the FR245. The Garmin Support replaced my HRM but problem was still persistent so they replaced the FR245 as well. Unfortunately with no success. Currently they passed…

Hi,
Garmin pushes update as soon as you use Garmin Express or if you connect thru Wifi.

You can avoid update :

* Removing the GUPDATE.GCD file, in /GARMIN, as soon as the device asks for an update.

I switched off vibrations but it didn't help. Changing to other FW versions didn't fix it either (I tried 4.20, 4.29, 4.41). Garmin should be aware of this problem but there was no feedback until now. I suppose and hope they are working on it.

My solution that seems to be working for two runs. I’m switching wrist heart rate off while in a run (with heart rate strap).

Try to turn off vibration and warning alert.

Garmin Support asked for more data. I assume the development department is currently (or at least from now on) working on it.

Great, I am also in contact with the support. So hopefully they will fix it soon and faster when more people have this specific issue.

French support just ask me to do a full reset of the 245, in order to try to fix the issue...

Did anyone do a run with a cotton or none synthetic shirt?
After weeks of waiting this is the answer I got..

As I‘m currently injured I can’t test it to give them an answer. Would be astonished, if you can only get proper data when using a cotton shirt lol. Don’t know if I should laugh or cry

You can just switch of wrist heart rate monitor.

But I’m about to throw the thing away. I’ve got my 2nd replacement watch, I’ve got two heart rate monitors. Former Member, please pass info to your colleagues to fix the software on the watch.

I‘m wondering that switching wrist heart rate monitor off is working for you.
Then at least 3 working 245M and 3 heart rate monitors already got scrapped for no reason.

I will probably try to get my cash back if the support won’t offer another solution. It would be such a good watch but that’s really a pain in the ass.

Will try to get my money back now and get a FR645M. Hoping that this issue doesn't appear on that device.
