How to Find Nordic Beacon Using BLE onLeScan() for Android

[RaQ]

I'm an Android developer and I bought the NRF51822-Beacon kit. All I want to do is be able to "see" the beacon using Android's onLeScan() bluetooth call. However, the beacon doesn't register at all. I can see other BLE devices, but not the Nordic beacon. I have the battery installed and the purple light is flashing which should mean it's beaconing. I don't want to use the Nordic app to "see" the beacon---the whole point is to be able to do it in a generic Android app. Do you know why I can't see the beacon? Is it even possible?

Yes, I can see the beacon using the Nordic app. I can see other BLE devices using onLeScan(), but not this one. I'm using Android KitKat 4.3. Do I need to install certain firmware or software on the beacon first in order to see it? I would not have thought so, but I haven't really worked with hardware itself before, so I'm not sure.
