Smart Ultra 6 has ANT+ capabilities.

I think I discovered something today that maybe Vodafone is unaware of - google found no useful links....

It seems the Smart Ultra 6 is ANT+ ready.

I played with an ANT+ HRM strap, and endomondo. I managed to record my heart beat.  I had to install ANT Radio Service,   ANT+ Plugins Service and ANT USB Service (the last one should be unnecessary, but endomondo was convinced I didn't have an ANT+ compatible device).  

Anyway, Endomondo then strava then ANT+ Heart Rate Grapher all recognised the device.  I went for a quick ride, and got sensible HRM measurements.

The strap is this one.  

So, if you want to use it with other ANT+ devices - definitely worth a try.  Happy to answer any questions I can.

 Doesn't seem to work since the Marshmallow update

@jefmcg

Have you tried uninstalling and reinstalling the app?

Let us know how you get on.

Thanks for the response.That wasn't the solution (I did a factory reset after upgrading) BUT 

... the problem was my HRM wasn't working!  I borrowed a friend's, and it's all good.

Ant+ is working fine with the Marshmallow upgrade.
