问题
I am using iBeacon for calculating distance between one iPhone to another iPhone indoor. I am using UUID and paste in code. But i did not get the distance from one iPhone to another iPhone indoor. i am writing the code like this.Can any body help me please. I got the error like this: CBManagerStateUnsupported. and one more issue is: [CoreBluetooth] XPC connection invalid
