Can anyone point me towards a tried and tested development kit (board) for Bluetooth Low Energy?
I am especially interested in the proximity profile, and compatibility with smartphone (especially iPhones and Android devices - but also any other that would have BTLE).
Also, can you tell me which smartphones would support the proximity profile?
I note that tod list devices that have BT4.0 functionality. Of course that does not guarantee that APIs will be exposed in the SDK. If you stick with an already implemented profile then you may be ok but as I said, you certainly will not find that in the Android API16. SO, custom implementations. One of the nice things with BT LE is that profiles are relatively "light" and hence, you can pretty easily make your own...but if the phone side API does not give access to the lower level (only talking GAP and GATT here) then not much use..
