title: Making ios7 BLE peripheral to work in background
body: <p>I have read every related information about it, but still can't make my iOS7 device work like peripheral advertiser in background. It works fine in foreground, but in background I can even discover it. I added <strong>App shares data using CoreBluetooth</strong> in plist file. I read that after going in background it puts my custom UUID in overflow data. I tried this one too(but no luck).  </p>
  
  <pre><code>NSDictionary *advertisingData = @{
   CBAdvertisementDataServiceUUIDsKey : @[CBUUID UUIDWithString:TRANSFER_SERVICE_UUID],
   CBAdvertisementDataOverflowServiceUUIDsKey : @[CBUUID UUIDWithString:TRANSFER_SERVICE_UUID]
  };  
  [manager startAdvertising:advertisingData];
  </code></pre>
  
  <p>In the central from other side (MAC OS app), I am scanning only for my: <strong>TRANSFER_SERVICE_UUID</strong> service. Is there something that I have missed that I should implement additionally in the central side?</p>
