HRM Dual connecting to app but not displaying BPM

Hi, I just got a Tacx NEO 2T. When connecting my Garmin HRM-Dual to my Iphone, I can see the sensor from inside the app but it doesn't show the BPM on the screen. Does anyone know what the issue could be?

This picture shows both devices connected (HRM dual and Tacx Neo2T trainer), you can see all the data coming from the trainer (Watt, Km/H and RPM) but the BPM is null.

Thank you to any help you can provide.

I fix the problem. Update an HRM dual by connecting the HRM to another compatible Garmin device (a Tacx does not work) that can be connected to Garmin Connect. You then need to connect that second device…

In the meantime I got a feedback from Garmin. "They are aware that some users are experiencing this problem and they are working on a solution". Let's see how long it takes.

There are multiple threads about this issue. One or more people said it started with an iOS update in Nov 2020 on newer iOS devices. Older iOS devices can receive the data flow from your HRM Dual.

I have the same with my new Tacx and the training app. HR displays on the bike but not in the software, despite relinking. I might try my old bluetooth-only HR belt.

I have the same issue as everyone else so wondered if you tried the Bluetooth only Atari and if it worked ok?

Mine now works fine with a Bluetooth only HRM.

I was having the same trouble in Sufferfest as of May 2021. Someone suggestued using an older iOS device. I found everything worked fine on an older (2016) iPad, but no HR number on newer iPad/iPhone.

If you are wearing a HRM chest strap it can only bluetooth to one device at a time. If you want to see HRM in the TACX app u need to disconnect it from your watch

I have the same issue with my Garmin Dual HR Sensor but if I swap to my Coospo HR strap (also Bluetooth and Ant+) it connects and displays HR straight away.

any news from Garmin ? basically my Garmin HRM device is useless for me since November 2020 . That's unfortunate ,when you by a garmin device you expect it to be compatible with other Garmin devices .

Garmin replaced the strap for me and the new one worked fine.
