To connect to BLE devices I am using the code you can find here:

I am running the code on my macpro with bluetooth activated. I can connect to my cell phone in the settings-> blue tooth menu but unfortunately when I run the code I only get the "CoreBluetooth BLE hardware is unsupported on this platform" output on the console. I do not have a developer account yet, can this be the problem?
CoreBluetooth isn't supported in the iOS Simulator. You'll need to run the app on an iOS device that supports Bluetooth LE. You will need a paid developer account in order to run apps on the iOS device.
