External HR Straps don't work with 10.43 on Enduro2

I just checked mine with my HRM-Pro+ and am not having any issues.  It connected right up.  I had it on BLE.  Switching to Ant+ also just works.

What other sensors do you have paired/connected?

Have you tried power cycling your Enduro2?

Yes, as per above I have tried power cycling the Enduro2 multiple times. The only other sensors I currently have setup on this watch is a Stryd because I hadn't needed things like inReach since I got the Enduro2 so hadn't set it up yet.

My stryd needs re-charging so not sure if that has been affected by the software update or whether it will still connect as stryd battery was dead today when I noticed this issue with HR strap.

Have just removed the stryd from my Enduro2 so I now have no sensors setup (I previously removed my HR strap and couldn't add it back).

Watch still doesn't find anything when I search for my HR strap.

From DCRainmaker said he and his wife were not seeing any issues at all (like you) but he knew of multiple people who were so there must be some specific setup/usage that is not working.

All I want now is to be able to downgrade to the old version... I didnt actively care about upgrading but just let it go ahead as have never really had issues like this with production releases on any of my Garmin watches over the past 10+ years.

Major bummer.  Of course it has to happen just at the start of a long holiday weekend

Good call on checking if removing Stryd might help since they've done lots of stuff with running power recently.  Were you able to add that back without issue?

Unfortunately I can't help you with the downgrade option.

 Not seeing any problems connecting to external sensors on my Enduro 2 either. If you want to revert to earlier software you’ll need to get hold of one of the alpha releases of software via the Garmin Beta program. 

Wow….so I emailed garmin to tell them about this issue and basically got an “f you” answer because it was a polar HR strap. We don’t guarantee 3rd party HR straps will work so speak to the manufacturer….cannot give you any support…

erm it worked until you updated the software…and by the way I also have an HRM4 garmin strap that has the same behaviour so maybe will you support me now!?…as someone who has spent over 5 thousand dollars on your watches over past 5-10 years. What an utterly crap response.

I am sorry you have an issue with your external HRM. Your watch should work fine with a HRM whether our own or other manufacturers. Your v10.43 software update may have gone sideways on your watch causing your issue. My sincere apologies.

Regarding when you reached out to Product Support in your region, please reach out again. If possible, call into Product Support. If you continue to be told you cannot be helped, please ask to speak to a Team Leader.

I believe this person was able to resolve the issue by using an old alpha download package to downgrade his watch — at which point the Bluetooth connection to the phone and all of the BT and ANT+ accessories started working. He then redid the OTA upgrade and everything stayed working. So it was somehow an error in the firmware update process that lead to this failure mode.

There was a thread on DCRainmaker. 

Hello, did you solve this hr strap issue?

Im facing the same issue with HR straps, tried everything and behaviour is still the same - cant connect or disconnection of the strap after 10min and unable to reconnect.

I’ve possibly being lucky but I’ve had no issues with my HR strap (Garmin HRM run) with the 10.43 software, connects fine and disconnects with no issue. Also the data provided seems very accurate as you’d expect from a HRM strap. I have turned off ‘Auto discover’ and always disconnect my HRM once I’ve finished my activity to save it constantly searching and trying to connect. 

I had no issues a week or two ago.

Yes, this is also my setup - turn off discovery and turn off ext sensor for connection.

im on 13.22.
