I've been trying to make some sense out of this gamut of devices and applications. As I understand it ANT+ is a Garmin protocol which is being challenged/supplanted by Bluetooth. When I got my Trek FX 7.6 I bought the Bontrager Cadence/speed sensor. It works with the Node 1.1 device mounted on my handlebars.

I also have a Samsung Galaxy S3. I noticed a handful of APPS for the S3. As far as I can tell IPBike works with ANT+ but you have to have two applications installed on your S3. From SelfLoops website:

The mini ANT USB stick consists of a cable adapter (micro USB to USB (F)) and the device for $53.00. So...when you have that you also need an ANT+ HRM..right? I bought an Axiom HRM for $39.95 at Performance Bikes a few weeks ago. It works fine but I wondered if it may be ANT+ compliant? (I think not). The reason is I have a Life Fitness Elliptic which has a heart monitor but you have to hold both handles and contact the silver metal plates on each bar for it to work. It's kludgy, but it works. Well, yesterday I put the Axiom HRM on and lo and behold the heart rate started showing on the Elliptic console even though I wasn't holding the handles. It had to be the HRM because it mirrored the values showing on the HRM wrist band. It also changed in sync with the wrist band.

Does anyone know what the heck is going on here? What type signal is the Axiom outputting?

So.. I have an ANT+ compatible cadence and speed sensor, the matching Node 1.1 display computer, an Axiom HRM and display band and a Samsung Galaxy S3 which works with a USB adapter. It would be nice to have the various parameters captured during the ride along with the route. Do I need to get a special HRM which works with the USB sensor? Is the Bontrager sensor compatible with USB?

Anyone knowledgable with this lashup?

Thanks, Rich
