Garmin Bluetooth HR monitor won't connect

I’m using a dual Bluetooth and Ant+ Garmin HR monitor and I can’t get it connect to Zwift. Either through my phone using the companion app, or with Zwift directly through my Win10 computer.

I understand there may be an issue with other apps using the Bluetooth connection, but I can’t find a way to stop this. I have forced shut Garmin Connect and Health apps on my phone, but I still can’t get a connection.

Any help on disconnecting all phone apps (except zwift companion) from the HR bluetooth connection?


Did you check your phone’s Bluetooth devices? It’s possible the HRM paired to the phone itself and Bluetooth is a 1 to 1 connection so once it’s linked it’s not discoverable anymore. Whereas ANT+ can connect to an infinite number of devices simultaneously

Hi @Ben_de_Groot and welcome to the forums! I haven’t been able to connect with my Garmin dual HRM since the update at the end of October. Here is a link to the thread on this topic and the ideas that several people have had. It seems that some people are able to find a workaround and some aren’t :
Good luck, and if you find a solution, please post it!

Thanks for the reply. Just saw this. Ya the HR monitor isn’t connected yet. Also the problem is if it does connect to the phone I can’t disconnect it. Not an option for the HR device on my phone.

Hi @Beth_Klawun thanks for the reply. Sorry I should check this more often after posting a question.

Don’t think is WiFi related. I can’t change my frequency on my mesh network anyway. I’ve deleted almost all other apps on my phone that could be reading my HR (RGT, Garmin, Tacx) the only one left is Health. Hopefully that does the trick (or helps).

Thanks for your help.

I have noted that most of this happened with Garmin HRM strap, zwift on iOS (iphone/ipad). I’m using chinese made HR strap, windows 10 laptop and android phone. all connected to 5ghz network. Been running perfectly ever since. Recently also bought Garmin fenix 5, now I connect the watch to my cadence sensor, the HRM is shared on bluetooth to Tacx flux and on ant+ to the garmin, simultaneously.

Actually with smart trainer that comes with power meter, HRM strap only serve one purpose, for us to monitor our heart rate so that we wont over exert our cardiac capability

Hi @Ben_de_Groot,

Have you found a solution yet? I finally ordered the 4iiii Viiiiva heart rate monitor to use as a bridge so I can connect HR and cadence together as one signal to my Apple TV. The trainer is then the other signal. In my test just now, it worked. I have a workout that I need to do this afternoon, so we’ll see whether everything connects again and whether the signals all hold. Or maybe the latest update that was supposed to contain a bluetooth fix helped you?

Just wanted to check back,

Hi Beth,

Thanks for checking in. I’ve given up on Bluetooth and bought an ANT+ dongle. HR monitor connection is great, but my trainer lost connection the other day.

Nothing seems to be easy. Although most of the time it’s good.

If my trainer drops again, I may go HR on ANT+ and trainer on bluetooth.
