If you change line 40 in WirelessBandManager.m to have a UUID of your peripheral, are you still able to get all the way through the didConnectPeripheral delegate? It doesn't work for me, I never get connected.

If I use the scanning method, I can find my peripheral and connect, including getting the didConnectPeripheral delegate called. However once I get my characteristics and start receiving data, I get corrupted/duplicated data (If my peripheral sends two segments of data on two connection intervals, I get the second data segment duplicated on both calls to didUpdateValueForCharacteristic).

Thanks for your help - I'm sure it is something stupid I'm doing, I just wish I knew what!

I'm not sure either but it works for me pretty well. Though, I haven't tried to read or write characteristics. Do you have any clues why you would need the CFRunLoop? The reference says:

The main queue is automatically created by the system and associated with your application’s main thread. Your application uses one (and only one) of the following three approaches to invoke blocks submitted to the main queue:

Calling dispatch_main

Calling UIApplicationMain (iOS) or NSApplicationMain (OS X)

Using a CFRunLoopRef on the main thread

If the main thread is used, then any of these should suffice and the same should be enough when a different queue is used as those are mapped to a thread pool and fully managed by the system.

Not sure, but dispatch_main() might not be enough. You might have to actually run the runloop with CFRunLoopRun or something similar. I know that works because I've written a CoreBluetooth command line tool and it works fine.
