public class BLEServiceDiscovery
extends java.lang.Object
implements datahop.BleDiscoveryDriver
```
BLEServiceDiscovery class is used for service discovery using Bluetooth Low Energy (BLE) beacons. BLEServiceDiscovery is responsible of scanning for BLE Beacons and starts a connection to the GATT server when found BLE Beacons with the same service id. Characteristics are compared in the GATT Server when accepting connections to compare status for each "topic". When detected different values of the "topics" it receives network information from the server.
