Problems with Ant+ connectivity

Hello, I also observed the HR dropouts from F5 + HRM-TRI.
Fenix 5 is working fine with Polar H7 because it uses the Bluetooth connectivity instead ANT+ which is used by F5 and HRM-TRI. And I conclude that this is a hardware problem (maybe ANT+ antena ) :(.

Here is what my fenix 5 + HRM RUN looks like with 30 minutes of running, also notice the way off low reading at the start, and then towards the end when i just got fed up becuase the HR just started dropping rapidly despite increasing pace and effort.

Finally able to post pictures :).

As you all can see in the attached pictures, there are some significant dropouts from Fenix 5 + HRM-TRI throughout the whole training, and no dropouts from Fenix 5X + the very same HRM-TRI. The exercises take place the same day just a couple of hour in between.ciq.forums.garmin.com/.../1228131.png

Not quite sure whats going on here, pace is still the same (it was only a gentle walk) and towards the end the HR suddenly increases for no reason. Using a HRM-tri

N O - M O R E - D R O P O U T S - a simple remedy

Hi, everybody who experiences HRM dropouts. I do not think that the dropouts have something to do with the ANT+ connectivity. The problem is much simpler as I found from the evaluation of the HRM records. The problem is due to fact that Garmin apparently did not consider the perspiration when designing the HRM belt. I had constantly dropouts after some time from the start. Then it came to my mind that it might be due to perspiration.

I recommend you to use a very simple remedy - put two paper tissues under the belt where the HRM sensor is clipped on.
You will never see the dropouts any more.ciq.forums.garmin.com/.../1228376.jpg

haha can?t tell if you?re serious. So should I wrap my power meter and stryd in tissues?

anyway. I returned my 5 and bought a 5x. No drop outs for me anymore.

Good luck everyone

But if your point is true why isn't the problem visible on Fenix 5X, only on 5?

as seen in my post, same HRM-TRI was used with both watches, and ONLY dropouts on Fenix 5.

A pity, my my case is closed since I have a brand new Fenix 5X and HRM-TRI :).

Also, the fact that Stryd only officially support 5X and not 5 or 5S must mean soemthing.

Hi, I recently installed a shimano group DuraAce Di2 on my bike. I have also installed the Shimano dfly. I have managed to link it with my Fenix ​​5, recognize the Di2 and give me the data in the cycling fields. But I can't do that works is the buttons on the Shimano handles to change the screens on the clock. I have seen on the internet that in the menu accessories of the Edge you can configure the buttons, but that is not possible in the Fenix ​​5. Is there any firmware problem? I also do not see the option in Garmin Connect or Garmin Express. Thanks.

I was disappointed with Fenix 5, so I ordered FR935. I was able to test them both side by side for 1 week. FR935 has 2-3 times better range of ANT+ and Bluetooth. No HRM dropouts even if I went to another room (i.e. good reception through a wall or floor).
There must be something wrong with the Fenix 5 design. I doubt that Garmin will fix this issue by a firmware fix. I suppose they will only hide dropouts by software.

The problem IS in bad Fenix 5 ANT+ receiption.
I tried 3 different watches (Fenix 5, FR935 and FR910XT) with 3 different Garmin HRM belts at the same time. Only Fenix 5 had dropouts with all 3 HRM belts. FR935 and FR910XT didn't have dropouts with any belt.
Furthermore, when I tried Fenix 5 with HRM-TRI, it showed dropout, but later when I downloaded stored HR data from the HRM-TRI to watch it didn't show dropouts anymore - it means that HRM-TRI recorded HR data correctly (and stored them in its memory), but Fenix 5 was not able to receive all transmitted data.

The ANT+ receiving issue is easily reproducible:
1. Put HRM belt on your chest
2. Pair it with Fenix 5 and start workout
3. Put your hand with the watch above your head or behind back and signal will lose after several seconds
