Estimote Beacon not able to detect in android device

I am new in Hybrid App development using cordova, I am using nodejs for developing and building cordova base android app.The purpose of the app is to scan any proximity device in the range. The plugin “cordova-plugin-estimote” is used for scanning.
The javascript and html file as in below link
Estimate Beacon not able to detect

The problem I have faced is when the device ready the event “onBeaconsRanged” is calling successfully but beaconInfo.beacons array length is always zero.

please check the attached file for your reference

Please help…

Can you detect your beacons in the Estimote Android app, available on Google Play Store?

Yes, We have checked through Beacon Scanner app.

Sorry for the delay… Thanks for your reply
