I have implemented a application to check whether bluetooth is ON/OFF using CoreBluetooth.framework but when i run that application on my iphone 3GS device it shows that the device does not support bluetooth low energy. please anybody help me with this or just a hint about any other bluetooth APIs that supports for iphone 3GS also appreciable.
Thanks
CoreBluetooth framework is only available in iOS 5.0+ and the hardware for Bluetooth 4.0 is only currently included in the iPhone 4S, iPhone 5 and the new iPad. Your 3GS does not have the necessary hardware to support the CoreBluetooth framework calls which is why you get the message you get.
