Applicable PACEdge Versions: 2.3
Prerequisites: Internet Connection
Summary:
Example shows how to handle with data transmission over unreliable networks. There are many solutions to this problem, but in this particular case we will show how to take built-in advantages in Node-RED MQTT Client, as well as how to use Queue Node.
Steps:
1.While having PACEdge connected to the Internet, install additional nodes:
–node-red-node-ping
–node-red-contrib-queue-gate
2.Setup two PACEdge systems, one to experiment with Node-RED flow, the other to use as an external MQTT Broker, where user can easily unplug the cable
3.Experiment with native MQTT Client message buffering capability
4.Expand experiment to add Queue Node to gain message buffering over the longer period of time
