HR Broadcast problem

i have the same problem with an Edge 1030. It looses the HR after 15-20 minutes even though Vivomove is still broadcasting

I did several test, and obtain the same result:
- I try to disable the bluetooth on the watch but again after some minutes it disconnect
- I connect the watch to the phone with USB Ant+ receiver and Ant+ Demo app,
after some minutes the watch disconnect from the app.
From the app I did a search for hr sensor but at this point nothing is found

Finally I think the broadcast hr functionality on the watch is broken and/or bugged

I repeat the tests with the new firmware (3.50) but unfortunately the problem is still there

Same problem here. My Edge 1030 sees the watch almost immediately after switching on broadcast, but after around 20 minutes the heart rate on the Edge display remains static, with a pull down of the menu I can see the heart symbol is no longer highlighted. The Vivomove indicates it is still broadcasting so I stop and restart it and immediately it is found again by the Edge only to last another 20 or so minutes. Repeat til end.
Firmwear glitch. Please fix.

New Firmware 3.60, new tests... the functionality is still broken:
1) after some minutes stop (5, 20, 45, 60 minutes in a random way)
2) sometimes when the broadcast stop the watch show "--" (look the attachment)
3) after re-enable of the hr broadcast the data are totally wrong (to compare the data I use a garmin chest strap)

Same problem is on my vivo move hr and garmin edge 820. My vivo move hr is the latest firmware 3.50.( 3.50 is the latest version in my country )
I asked support center about this problem and told this thread.
I had a reply from support center 27th feb.
They said that Garmin Japan was recoganized this problem and fixing program (now debugging) but they didn't tell me release date of fixed firmware.

last weekend I did a 3h ride, with the new firmware 3.70 the vivomove stop to send the HR four times
and when working the HR is totally wrong, less than 100bpm

I have had this problem in just the past few days, with the latest OS (3.7). I have observed two different failures; sometimes after periods of time (sometimes 20 min., sometimes 40 min.) the watch leaves broadcast mode entirely (almost like a "crash") and I have to re-enter the broadcast mode from the home screen. Other times it will appear to be broadcasting, but the receiving device registers nothing.

Hi all,

I also have the same issue with my new Vivomove HR. I am running firmware 3.7 but have the intermittent issue with my Edge 520 when cycling as well as with Strava on my phone when running. (Samsung Galaxy A3 (2017)).

I have logged the issue with Garmin technical "gurus" and am awaiting a response.

It is very annoying and must be able to be addressed in a firmware update.

It is comforting to see its not just me with the issue.

I am posting this to increase the number of posts on the topic.

Tez.

Same issue with my EDGE 510. VivomoveHR disconnects regularly, thought it was to do with Bluetooth connections with my phone but turning them off everywhere made no difference. Device is week old and I have everything up to date.

Have to turn off HR broadcast and then restart. Okay on relaxed smooth ride but impossible on MTB or if riding hard. Screen shot of HR data from MTB ride included. Bought device only so I could track training progress as I hate putting on chest strap.
