EAAccessoryManager connectedAccessories returns empty array

I am using EAAccessoryManager to connect my application to a MFI accessory. During the initial connection, in bluetooth setting screen, it showing as device connected. When i try to get the list of connected device using "[accessoryManager connectedAccessories]", it returns a empty array. But when i use "showBluetoothAccessoryPickerWithNameFilter", it shows me the accessory in the list. The problem is i don't want user to choose the accessory. I want to make this a automated process. I have included the accessory protocol string in info.plist too. Please guide me with this issue. What mistake i am doing here ?
