Does the iPhone simulator in Xcode support Bluetooth Low Energy?

I'm trying some iOS test applications on the new Mac mini, that supports Bluetooth Low Energy. The CoreBluetooth framework is used in those. However, I'm not able to get Bluetooth working in the iPhone simulator, that is part of Xcode.

When I allocate a new CBCentralManager, centralManagerDidUpdateState: receives CBCentralManagerStatePoweredOff which stands for Bluetooth is currently powered off.

The first time I ran the text application, a box was then opened up that looked pretty bugged (only language variables were used, not the actual texts) and with two buttons. The first led me to the settings panel where there was an option to enable Bluetooth. However, after I told it to enable Bluetooth, it just shows the spinning animation, and it won't either complete or cancel. Even after rebooting the Mac, there is still only the spinning animation. The box also does not open up anymore.

Essentially, I think that the iPhone simulator should support Bluetooth Low Energy. Otherwise, it does not really make sense that there is an option in the settings application on the simulator. Also, the central manager state is CBCentralManagerStatePoweredOff but not CBCentralManagerStateUnsupported which would stand for The platform doesn't support Bluetooth Low Energy. This gives also hope that support could exist.

• Does the iPhone simulator support Bluetooth Low Energy?
• If yes, how can I enable it?

The simulator does support Bluetooth Low Energy (4.0) according to this appnote from Apple. The only problem is that even if you have a computer with BLE inside, you will not be able to use the simulator together with it, because (I think) you occupy the availability on BLE for other devices to discover your computer, thereby restricting the functionality of the Mac.

So if you go get yourself a BLE USB dongle you will be able to use it in simulator.

EDIT: Adding information from @JoeShaw:

Unfortunately it appears as though Core Bluetooth support has been dropped from the simulator for iOS 7. Reference: doubleencore.com/2013/09/whats-new-in-bluetooth-le-ios-7. In addition, the linked technote seems to have been removed.

I have been using the simulator to test BLE apps - but you need to be on OSX 10.7. As Wilhelmsen mentioned, you also need a BLE USB dongle. In addition, you need to set an NVRAM setting:

$sudo nvram bluetoothHostControllerSwitchBehavior="never"

See this Technical Note from Apple for more details on using the simulator to test BLE apps: http://developer.apple.com/library/ios/#technotes/tn2295/_index.html

According to http://www.doubleencore.com/2013/09/whats-new-in-bluetooth-le-ios-7/, Core Bluetooth support has been dropped from the simulator as of iOS 7. I haven't figured out why yet, but it means you will need to test on real hardware in the future.

It also appears as though Apple has removed Tech Note 2295, as I get redirected when I hit the URL.

I've found that Apple writes in their own samples that the simulator cannot be used to test Core Bluetooth-based applications.

Important: This project requires a Bluetooth LE Capable Device (Currently only the iPhone 4S) and will not work on the simulator.
