Just switched from Zwift to Trainer Road because of previous connection issues (my cadence sensor/HR would randomly drop). TR has been much better with connections but for some reason my Garmin DUAL-HRM will connect but the HR just shows up as “–”. It is connected by bluetooth I have troubleshoote…

I have the same problem. Interweb shows people having this issue throughout the year. I started having it a month ago, not sure what changed. Works fine on my edge 530 but seems to have issue with my iPhone (either TR app or using it to connect sensor on zwift). It worked yesterday through Apple TV…

Same issue here as well. Battery shows at 85% so that isn’t the issue. I have it paired with my Garmin 945 and off my wrist and it shows the HR fine. Googling seems to indicate it might be some issues when its connecting across multiple devices but as far as I can tell there’s no way to check what …

Had the same Win10 desktop. Hit Forget Device and re-paired. Works Ok now

That’s interesting. My battery is also stuck at 85%. I’m emailing with TR support services - I’ll let you know if something comes of it.

I’ve had an issue since I switched to the Garmin Dual about a month ago. I run the app on my iPhone (or MacBook) and simultaneously run my Garmin 1030. I have found that I can only be connected to 1 Bluetooth device at a time, and it seems to remember the device it was last connected to. Since th…

[image] Pbase: I run the app on my iPhone (or MacBook) and simultaneously run my Garmin 1030. Maybe I’m missing something here, but why not connect the Garmin Dual to your iPhone/Mac via Bluetooth and to your Garmin 1030 via ANT+? I do that (tablet=Bluetooth, 1030+= ANT+) and it works great. …

Nice catch. I stand corrected. I am connecting to the dual with ANT+. I am then attempting to connect to the phone with Bluetooth and while it shows as connected, it is not displaying the HR on the phone.

Hey everyone, Just to update everyone. I went through Trainer Road’s support team who were very helpful. They ran me through a bunch of troubleshooting which didn’t help. They finally suggested that maybe the Garmin HRM was the problem so I ordered a new one - and it WORKS! Looks like the issue…

I had the same issues as here described, HRM worked fine on all devices and all apps, except on the iPad. On the iPad it connected to the HRM, but got no HR data. This happened after I had to change the batteries on the HRM as old ones were empty. After that, the TR app on the iPad just gave - - as…

Solved with complete phone reset. I experienced the same issues with the Garmin HRM and cadence sensor both reading null (–) on my iphone XR but this only happened after updating to the new TrainerRoad IOS app, released in March. Prior to that they had been working fine since I began TR 9 months p…
