Once you have properly setup your sensor broadcaster and XPLR-IOT-1 Gateway, you should be getting MQTT messages containing a JSON representation of the measurements in your Thingstream account, at the IP Thing assigned to your Gateway.
These measurements are published in the topic defined by the following definition in Gateway main.c file
// Topic name where the received measurements are going to be published
// Should be defined to Thingstream as well
#define MQTT_TOPIC "timeofflight"
In order to be able to send those data to a Node-RED dashboard for visualization a flow should be created in Thingstream to publish those measurement data to the dashboard.
The steps to follow are given below
Create a topic in Thingstream with the same name as the MQTT_TOPIC definition in Gateway code (default: timeofflight)
Create a flow: Go to Thingstream -> Flows -> Create Flow -> New Flow
Give a name to your Flow and then add nodes as shown in the picture below:
Double click the last node (Publish to XPLR-IOT-1 TOF Dashboard in the picture) and assign a dashboard topic to it
Deploy your flow to the MQTT_TOPIC from step 1.
In order to do that:
-
Press the deploy button in the upper right corner in your flow view
-
Press the edit subscription button
-
Choose the
MQTT_TOPICcreated in step 1.
- Hit the deploy button
- Check that your flow is subscribed to the correct topic.
