The Bluetooth Feeder is an OSGi bundle designed to log BLE beacon messages. Specifically, the Bluetoot Feeder detects:

• iBeacon
• EddyStone
• EddyStone TLM

The bundle requires to interact with a BLE USB dongle (detected via RXTX serial lib) through which the Bluetooth Feeder can listen for BLE messages. The Bluetooth Feeder interacts with the USB dongle by means of the bglib protocolhttps://github.com/SINTEF-9012/bglib/tree/master/bglib-protocol-1.0.3-43 (provided by SINTEF). As soon as new message is received, the Bluetooth Feeder parses publishes it through the middleware API. The topic used for publishing the messages is:

dataFeed/context/beaconX

Where X is the ID of the receiving device (see below). Message sent to the middleware has

The data feed describing the messages is:

sender
rssi
packet_type

You need an BLE USB dongle plugged on the instance you are provisioning with the Bluetooth Feeder.

• On windows OS: the USB dongle is usually recognized as COM port (ex: COM3)
• On Unix OS: the USB dongle is added to the /dev dir (ex /dev/ttyACM0)
