How to config beacons with Indoor Estimate SDK in iPhone

Hi,
We are using Estimote iBeacons, and using sample Estimote Indoor SDK. We have also setup the App ID and App Token on Estimote web portal. And all purchased beacons are showing on that account.
But when we are trying to Configure my beacons, its continuous showing “Looking for beacons” rather then beacons found. And at last it said "No beacons were detected".

Are you signed in on the app?

Have you used app id and app token in your app. That is

[ESTConfig setupAppID:@"yourAppID" andAppToken:@"yourAppToken"];
