Is there a known issue with the 945 and HRM Run? I can’t get either of mine to connect anymore.

i can no longer connect my HRM run to the 945. I changed the battery, tried to refind even broke out my back up and tried to connect to no avail.

Is there a known issue here? Or am I the lucky one to figure it out? Or . . .

This is a bug, I can only use my HRMRun ONE time, then need to reboot the watch to connect it again. Firmware 2.50.
So on every run I need to:

- Reboot the watch
- Sync with GC as to have heat acclimatation…

Works fine for me, I always run with the HRM strap and had been getting the "external HR connected" message with the old (old!) HRM strap I was using. I just bought the HRM-Run (the latest, the one with…

No issue with my HRM run here, fw 2.50... did a run with it today (I don't always notice the 'external HR connected' msg though, sure it's not connected? Perhaps it is but you're not notified?)

Mine connects fine with FW 2.50, but it rarely shows ‘external HR connected’ message. You should look at Settings>Sensors&Accessories>HR-xxxxxx to see whether it is connected.

try to reboot the watch. I often find 945 wont find any external sensors. A watch reboot brings them back.

Works fine for me, I always run with the HRM strap and had been getting the "external HR connected" message with the old (old!) HRM strap I was using. I just bought the HRM-Run (the latest, the one with the red sensor) and I don't get that message any longer. The only way I know it was connected is because I can see the additional metrics.

Be nice if there was some sort of indicator next to the heart icon indicating an external source, or a status message that would come up when you cycled through that screen (easier to implement than the former idea)

Do you happen to have any other sensors you can try? A footpod, power meter, tempe, etc? I have had no problems connecting mine.

That did it. Should have thought of that myself - reboot is always everything when it comes to electronics. Thanks for the help!

super - nice to know a Watch Reboot worked and that it happens with ONLY HRM Run as well. I thought it might have been related to my Stryd sensor - but maybe it is the HRM Run that makes the issue.

When I select the Activity (so fx. run or walk)

1. With Wrist HR - there is no "Heart" symbol showing (When you are IN the activity before pressing start - the screen where top line say "Options" on the top line.)

2. With external old HRM-Run - it DOES show the heart symbol on the same screen.

You can also cheat - and "Enable Broadcast on Activity" - then it makes it even easier to make certain - as broadcast of HR ONLY works with Optical Wrist HR - and the Symbol is a Heart with some "wireless" jiggies on the top right. So if that Heart symbol shows with "jiggies" - you are using Wrist HR. If it shows just the Heart - you are using external HR.

I had the same issue earlier this week and the "big red switch" (reboot) solution also solved my issue.

I should have mentioned I was trying to connect to a HRM-Tri that had been previously connected and that was the only device I was trying to connect to. My 920XT was connecting to it without issue.
