AirVantage System Simulator

This application is a Node.js tool that sends system data into AirVantage using MQTT. The data appears in AirVantage as if the selected system had sent them (provided you have the right credentials).

Features

The application is composed of a single screen. It displays a form to configure your MQTT message and send it to the server. The form is structured as follows:

Identification panel

  • Server: Which AirVantage server you want to connect to: eu.airvantage.net (Europe) or na.airvantage.net (North America).
  • Identifier (IMEI, S/N): Identifier of the system you want to simulate. Depending on your system, it can be its Serial Number or IMEI.
  • Password: MQTT password of your system. It must be the same as the one entered in AirVantage, by clicking on the padlock icon in the system's edit screen.

Message panel

  • Data path: Path of a data or setting from one of the applications installed on your system. Check your Application Model in AirVantage for available paths.
  • Value: Value to send for this specific data.
  • Type: Type of the data. Must be consistent with the data type defined in your AirVantage Application Model.

Add data button

The Add data button dynamically adds a new data to the Message panel.

Send data button

The Send data button sends all the above data in a single MQTT communication.
