HR sync with zwift on iPhone

Former Member
Former Member over 5 years ago

I’m using zwift on iPhone.

My 245 has connected to iPhone through BT. The Garmin Connect app can show my HR.

When I use zwift on iPhone, zwift cannot find 245 for HR.

Is there any possibility to work it out?

(I know I can use 4iiii HR band to transfer the ant+ to BT, just not willing to do this for now, feel stupid as connected but cannot find it)

    Maybe you need to Enable Broadcast HR in Wrist Heart Rate on your 245?

    The 245 is only able to broadcast HR over ANT+. Unless you have an dongle for your iPhone to receive ANT+, you will not be able to use your 245 for Zwift on iOS. 

    Broadcasting HR does not function the same as Garmin Connect Mobile displaying your HR.

    I don’t understand why this is not possible.

    My 245 is connected to the iPhone, and zwift is running on iPhone, why they cannot share the hr?

    i have Topeak hr band, which uses bt and can use topeak app to read my hr. And I can use topeak hr band on zwift.

    I mean 245 and zwift are on the same iPhone, please just get them work! I know I can buy 4iiii hr band to transform ant+ to bt, just don’t want to do it now until I figure out why this cannot be done...
