How to connect to a Rogue Echo Bike V 3.0

I've started doing intervals at the gym on a Rogue Echo V 3.0. 

The website states:

This includes an improved LCD console that not only tracks intervals, distance, calories burned, heart rate, and more, but also now features Bluetooth / ANT+ compatibility, allowing users to connect to various cycling apps for even more performance feedback. 

I have a Forerunning 735xt watch and garmin HR monitor strap. 

What I would like to do is have the workouts track my HR, Distance etc and be able to see that in the app post workout. 

Could anyone point me in the right direction?

Thanks
