Beacons connect disconnect very frequestly

I have generated sample iOS app from “”.
But for me Beacons are connecting and disconnecting very frequently,
within second I am getting like “You are in beacons range” ,
next second getting you are out of beacons range.
And there is no pattern, suddenly you get in / out range message.

I am using iPhone6 (iOS 10.2.1) and Proximity Beacon

Have you changed any settings on your beacon? Does increasing the Tx Power (e.g., up to the max +4 dBm), or lowering the Advertising Interval (e.g., down to 100 ms) of the iBeacon packet help?
