After learning about bluetooth smart, I have been wanting to write some phonegap/cordova apps for my self. There are few plugins (1,2,3) available on github but in my opinion the most promising one is from EvoThings called cordova-ble. I decided to write my self a sample app for scanning on a weekend and ended up modifying one of the examples from EvoThings and mixing in topcoat and zepto as per phonegap expert recommendations. Code is here.
The code is dead simple, so I won't bother to explain it, but essentially it is just HTML5/CSS3/JS stitched together with the evothings plugin.
