Sdk and uuid on Android

I am working on nRF51822 ble_app_bps and I want to use Estimote SDK to monitor beacon on the background. I also changed UUID, Major, Minor value: UUID.fromString(“00001810-0000-1000-8000-00805F9B34FB”), 0, 0));

But the app doesn’t enter "onEnterRegion ", which is executed when the matching UUID is found.

What is the problem?

@Gary_Noh, unfortunately, Estimote SDK can be used only with Estimote Beacons and Estimote Stickers. That’s why you are not able to observe any packets broadcasted by other devices, even if the region is defined correctly.
