Concept

3

-  Connect devices and Sensors via LoRa/LRSC -  Connect to a Secure-WebSocket Data source -  Send the data into Watson IoT -  Create devices automatically based on the discovered sensors in WIoTP -  Use Node-RED for orchestration -  Monitor connections and messaging -  Turn the WebSocket/LRSC message into MQTT messages

Challenge

5

-  Connect to a Secure-WebSocket Data source using certificates/private keys

-  Be able to create IoT devices on the fly when discovered on the LRSC/LoRa network

-  Monitor the connections and messages

LRSC Bridge

-  Monitoring Connection

-  Transforms LRSC into MQTT messages -  Creates LRSC sensors as devices in WIoTP

-  Can receive commands from WIoTP Commands like: ping , info etc

Creates new Devices/Sensors base on LRSC network data/events

Sendind/receiing CMD via mqtt to the LRSC Bridge

Sending command/information to the bridge: like ping or info Note: the bridge will send a mqtt message back as confirmation.
