I believe on the Mac Mini's traditional Bluetooth is used when performing a scan.  If you want to use the BLE portion of it, I believe you have to use the SDK and right a seperate App for it

mai i use it with iTouch 4 or iPhone 4, or iPad 2?

no, the only devices that have bluetooth 4.0 from apple is the IPhone 4S, the New mac mini, the new mac book air, and the IPad 3

Thanks, this was my first problem.

Is there any reason why a HEX file isn't provided with the CC2540 Dev Kit software?  It's kind of annoying to have to set up an IAR environment just to get example's running.  Perhaps I just missed the hex file.

Thanks,

why this happen?

Hi Bob,

Any update regarding this interesting question ? I'm very interested to find a way to avoid asking characteristics after each re-connection.

hi fred,

according to apple, "caching" of characteristics is something they are investigating for the future....  as it turns *connect time* in general has been problem for a variety a reason besides having to re-discover characteristics....

you might consider posting a question on the apple bluetooth email list and/or a new forum apple has recently established....  perhaps you can find out a timeframe for such a change....

HI,

I checked with CB , that i don't  see any API, to create secured connected to the device ?.. Or before we create a connection to the device, do we have to use any iOS infrastructure to do the BLE pairing/authentication?.. Pretty confusion. Kindly advice. 

is it possible to detect nearest BLE ios devices using the keyfob code?
