Broadcasting HR from Forerunner 45 to Zwift

Hi all,

I have a Gamin forerunner 45. I haven’t get bought an ANT+ dongle as many don’t say they are compatible with the 45.
Does anyone use a FR 45 for their heart rate on zwift? Do I just need any old zwift compatible ANT+ dongle?

Cheers

Any ANT+ dongle should work.
