This a short demo of the LRSC bridge Node.js app which transforms LRSC messages to MQTT and sends them to WIoTP from a secure websocket connection form an LRSC App Server. The Bridge also creates discover devices directly in WIoTP

Concept

3. 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

5. 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

8. 8
Creates new Devices/Sensors base on LRSC network data/events

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