Bluetooth 4.0 to serial module - Angel health monitor

I need a bit of Bluetooth help there seems to be a mix of brand names:
Bluetooth, Smart, Smart Ready; not all will work with one another

I’m looking for a module that will work with this fella http://www.angelsensor.com/developers.html
It just states BT v4.0 at the moment

Also any quantified self-ers wanting to collaborate to integrated this with e.imp?
