  <p>This is what i have been set for background modes to use bluetooth and apple rejected app with given reason below :</p>
  
  <p>2.16 Details</p>
  
  <p>Your app declares support for bluetooth-central, and bluetooth-peripheral, in the UIBackgroundModes key in your Info.plist, but does not provide Bluetooth Low Energy functionality. The Bluetooth Background modes are for applications that communicate to other devices using Bluetooth Low Energy and the Core Bluetooth framework.</p>
  
  <p>Next Steps</p>
  
  <p>Please revise your app to add support for Bluetooth Low Energy communication through Core Bluetooth in your application or remove the bluetooth- values from the UIBackgroundModes key.</p>
  
  <p>Please help me out .... 
  Thanks in Advance !!!</p>
