No HR data from a HRM strap

My iPhone stopped receiving HR data from my Garmin Dual HRM strap. This happened after I acceped a pairing request for the device. I mainly use Trainerroad but also tested Strava. Both can connect to the device but show no value for HR.

I tested battery swap, forget device, sensor reset, phone restart and also updated to iOS 15. No avail.

The sensor seems to work as I can connect to my Garmin watch with BLE connection and also to my Mac book pro. Both receive data.

So this leads me to blame iOS for the issue. Neither Garmin support nor Trainerroad support could help with this. Based on other forums I’m not alone with this issue.

iPhone 8 Plus, iOS 15

Hello markku113,

Thank you for that information. This does appear that it could be connected to the app.

We did some additional research and found a thread that may have an answer for you at TrainerRoad:

Garmin HRM strap will pair with TR but no hr data shows?

Towards the bottom, there is a solution posted by a user which may offer some resolution.

Cheers!

I have tested all this. It NOT an app issue. I’m sure it’s an iOS issue that some update has triggered. The key seems to be the pairing screen iOS displays. If you accept it stops working.

Hi. It’s not Garmin Connect data I’m interested in. It’s the live heart rate monitor data. I’m trying to use a training app but don’t get the data from a bluetooth HRM wich IS connected.
