could i connect iPhone and collect data from other bluetooth device (it may be iphone , ipod, nokia or other blue tooth device, like PC and so on.) from my own application. ?
if it is possible which way is the easiest . like GameKit framework ?
pls help me
You are not allowed to low-level access to Bluetooth devices, also knowing apple and their policy on connecting external devices to their iPods, it would take some kind of chip and licensing deal for a vendor to be able to connect their device to an iPhone. So I am guessing that not all bluetooth devices will be abble to connect to your iPhone
Using the official SDK (GameKit) its not possible. To do something like that you would need to jailbreak your phone and try to use the BTStack framework. If you really want to do that, then Google it.
