Pairing Garmin watch

Hi! I’m wondering how can I conect myy garmin watch Swim 2 to zwift. For now i don’t have a ant+dongle,and I tried with bluetooth with the companion app,but it won’t conect,any thoughts?

It appears the Swim 2 and not broadcasts HR via ANT+ and the help site mentions to paired Garmin devices so I’m not sure it would even work with Zwift. Might want to post in the Garmin forums to get an answer or maybe another Zwifter who has that watch can provide more info.

The broadcasting HR i think will gonna work with the Ant+ usb… i saw that you can conect via Bluetooth(on ZC), and i tought that it can work with out it.
Im hopping that may answer another user of it, indeed.
