Every time on scanning bluetooth devices gives CBCentralManagerStateUnknown? -

The first time I am using Core Bluetooth. Here is my implementation, there is no wrong thing in it.

  @ synthesis chief minister, active refill; - (id) Init {if ((self = [Super Init])) {CM = [[CBC Central Manager alloc] initWithDelegate: Self-quote: dispatch_get_main_queue ()]; } Healthy return; } - (zero) viewDidoadload [[Super Viewedload]; // Setup an additional after loading the view, usually from a nibb. } - (int) scanForPeripherals {if (!

 This log returns every time  
  Core Bluetooth state is unknown (CBCentralManagerStateUnknown)   
  Updates   
 After the suggestion given by @Michael Dautermann to the question, I know that my centralManagerDidUpdateState representative method does not know why this is happening. I'm getting. If any reason Please do not let me know.  
 
 
 Core Bluetooth is just in the process of starting.  
 This representative method is required for you to hit first:  
  - (zero) CentralManagerDidupdate: (CBC Central Manager *) Central;   
 And once it happens,  then  you can start scanning for external devices.
