Reading RSSI of specific BLE Beacon


I am working on a project requiring the monitoring of a specific BLE Beacon which is advertising continuously. I am specifically interested in this specific BLE Beacon's RSSI while ignoring all of the other active BLE devices. Since it is a BLE Beacon it is non-connectable. I have used some of the previous BLE programs but have not been able to isolate a single device, either by name, address or anything else. Any suggestions??

Not by UUID?

I was hoping to use a custom beacon config that did not require a UUID but that may not be possible. I guess I'll have to resort to an iBeacon or Eddystone config. Thanks.
