Multiple Bluetooth Smart sensors for bike? I just bought a Sports Tracker Smart heart rate monitor that communicates via Bluetooth. Then I saw the cadence sensor that also measures speed and distance plus it communicates with Bluetooth Smart. I did some research and found out that there's a communication standard called ANT+. Neither of these devices support it. 

Is it possible to use these simultaneously with my phone that has Bluetooth Smart? Currently the Sports Tracker cadence sensor is not supported with Android (or not with their software at least. Maybe with something like Runtastic Road Bike) but they plan to release a software update in summer that makes it work on Android. 

Also, what softwares on Android you know that can support this combo?
Android can just about handle multiple BTLE sensors simultaneously but there are still some low level Android bugs that make it rather unreliable.  The coding for is also a good bit more complex to get working than the single sensor case.  I have support in my app IpBike via a beta version of IpSensorMan

At this point in time if you were getting new then an ANT+ based setup is the preferred route.  But if your looking to work with your current phone which is not ANT capable then you would need an ANT USB stick and things get messy.
