IPhone EAAccessoryManager returns an empty NSArray

I am new here and I suspect I am missing something obvious but web searches and reading the apple docs are not helping. I'm stuck so here goes.

I have an iphone 4 running IOS 4.2.10 with a Samsung HM1100 bluetooth headset connected. I am sure it is connected because the iphone general setting say so and the iphone responds when I push the call button on the HM1100. I can't upgrade to IOS 5 and CBCentralManager yet. The HM1100 is supposed to be iphone4 compatible (bluetooth version 2.1+EDR).

My iphone app is importing ExternalAccessory/ExternalAccessory.h

and the code has the following lines

NSArray *accessories = [[EAAccessoryManager sharedAccessoryManager]connectedAccessories];

NSLog( @"acessories %@", accessories);

The code compiles and runs successfully on the iphone attached to the Xcode 4 debugger on a macbook pro and prints out an empty array as follows.

2011-12-27 15:03:25.106 View Switcher[102:307] acessories (
)

I expected it to return at least one EAAccessory object in the array. I must be doing something wrong.

thanks, ab

As Brad Larson pointed out maybe your accessory uses standard bluetooth profiles (like handsfree profile) so it doesn't shows in the list.

EAAccessory is only for the Made-For-iPod licensed accessories. If it isn't licensed and everything it won't show up in the list. You can't just connect an arbitrary Bluetooth headset or other device.
