Programmatically turn on bluetooth in the iphone sdk?

Question

I have seen a lot of questions about this but no one actually gives a real answer (frameworks to import, actual code etc). They only say with a private api and that will get your app rejected from the app store.

I am aware that use of a private api will get my app rejected by I was wondering how to do it for personal use. (iPhone SDK 3.1.2, iPod touch 2g)

I've been looking into this as well. You need to include the bluetoothmanager framework and header file in your project. It should be in

/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.0.sdk/System/Library/PrivateFrameworks/BluetoothManager.framework/

If the header file is not there, you'll need to grab a .h file that was generated from the library and include it in your project. I googled to find it; Here is one here:

http://iphone-dev.googlecode.com/svn/branches/include-1.2-sdk/include/BluetoothManager/

Once that is added to your project, your import should look like this if the header file was already in the framework:

#import <BluetoothManager/BluetoothManager.h>

Or this if you added your own BluetoothManager.h file to your project:

#import "BluetoothManager.h

To toggle the bluetooth here is the code:

BluetoothManager *manager = [BluetoothManager sharedInstance];
[manager setEnabled:![manager enabled]];    

I have built a utility to do this myself and it does work. Note, if all you want to do is create a utility to toggle the bluetooth and exit, without any UI, create a new project in XCode and use the Window-based Application template. Add the code to the didFinishLaunchingWithOptions method and replace [window makeKeyAndVisible] with exit(0).
