The ibeacon driver uses a BLE4 module hm17 which is capable of bluetooth central role
it is driven by AT cmds so there may be other compatible modules too. [(hm17)](https://www.ebay.de/itm/HM-17-BLE-4-1-Bluetooth-CC2541-UART-Modul-Wireless-neuer-als-HM10-HM11-HM17/223189729091?hash=item33f724ff43:g:yxoAAOSweTlbw8l7) (hm16 should also work)

the hm17 is connected to GND , 3.3 V, RX to TX of ESP and TX to RX of ESP.
the module when delivered is in the peripheral mode and must be switched to central mode only once by the cmds
sensor52 1 and sensor52 2. the settings are stored inside the module.
sensor52 us sets the scanning interval in seconds s (5....n)
sensor52 us sets the (update) scanning interval in seconds s (5....n)
sensor52 ts sets the timeout interval in seconds s (10....n)
the driver reports all beacons found during a scan with its ID and RSSI.
