My fenix 5+ disconnects from my polar heart rate monitor after 7-8km into my run and requires me to stop recording the run and resume again for the HRM to reconnect... Very annoying

solved

polar model is #3 (ID 45577) using ant+ connection. Bought it 1+ years ago brand new. Don't know what ble is.

I know it disconnects bc hear rate suddenly drops from 150-160 to below 60 and then disappears with two "--" appearing on the screen.

wrist hrm doesn't kick in. When I look at heart rate recording of the run, it is steady at 150-160, then drops with a gap of no recording for a few mins before it reconnects and then suddenly shows 150-160 again.

When I just use wrist hrm, it consistently shows 160-170 (is higher than with polar hrm) throughout the entire run and doesn't drop. But it doesn't kick-in when teh polar hrm drops for whatever reason.

Can't be wrong iwth polar or watch since it perfectly connects at the beginning and records the heart rate between 150-160 for 30-40mins of my run but then suddenly drops and when reconnected records remainder of the run at 150-160. It somehow looses the connection in-between for whatever reason.

Model is H9 SS20-BK-M

solved

1) Have checked that before and it is only the polar that is present

2) ok will do that before my next run

3) how can I extract a fit file? Do i do this from the Garmin Connect app on my phone or from the watch directly?

4) No, bc the polar connects. It is the Fenix 5+ that looses the connection to Polar and doesn't switch to the wrist hrm. It is a defect on the watch, not the polar. I also use an Edge 530 for cycling and connect my polar there and it never looses connection. My watch seems to be faulty!

5) absolutely, I take the pod off and clean it extensively and rinse the strap in warm water. it is well maintained.

Thanks

Took me a long time to figure this out but hope you can open that zip file.....H9 battery is ok, I regularly check and have also swapped it with a new one even though old one was still good.....
