Only thing I didn't get it to work with is some cheap ass FitBit (which it works with) clone. From the reviews I read later, it seemed hit and miss with other kit as well.
I've had more issue getting android stuff to talk than Win mobile.
It may be the case I don't give a damn about Internet of Shit stuff that I haven't found these issue, But then again, I'm able to press the white thing on the wall to get my lights to come on.
The only one I'd say you have a really good chance of getting everything talking well is the iPhone.
