- GPS – Which (if any) have Bluetooth HRM capability?
Not that I could find,
There is a bluetooth screen thing coming from wahoo but it still relies on iPhone. See if you bluetooth heart monitor vendor lists anything compatible, if it’s the Wahoo one like mine there is nothing shown.
You’ll probably get enough by ebaying it to pay for an ant+ replacement.

Coming at it from a technical point of view, for a standalone device, bluetooth has no advantages – it is higher power, so batteries run down quicker, it is often fiddlier to connect, there are more likely to be many other bluetooth devices around you, ant deals with dropped connections in a nicer way, and it offers no better connection or accuracy. Oh, and it is more expensive to license and build.
At some point newer low power bluetooth standards will probably make ant obsolete, and it will become cheaper to implement Bluetooth, but right now the only reason for a bluetooth belt is to talk to a general purpose device like a phone.
Either that or at some point all radios in devices will be software defined meaning it’ll be trivial to support different wireless protocols, at which point phones may support ant or similar.Posted 5 years agoGrahamSSubscriber

Joe, I think you’re a bit out of date.
These HRM devices (Polar H7, Wahoo Smart, adidas miCoach etc) already use the new Bluetooth Low Energy protocol (aka “Bluetooth Smart” or BTLE) which is designed for very low-power consumption.
In my opinion Bluetooth Smart is already winning the battle over Ant+. It has much better industry support and more importantly pretty much any modern smartphone already has Bluetooth 4.0 built-in so supports Bluetooth Smart by default, whereas ANT+ requires a different license and tuned radio.
This guy sums it up nicely:
