# rolling-stock-display-simulation-tool

A tool for connecting virtual devices to the Rolling Stock platform. 
Devices need to be registered and credentials prepared in a JSON file 
put in input.json (or specified in a variablle) 

Sample input.json file structure: 

```
[
{"username": "DEVICE197", "host": "rolling-stock-sandbox2-openfire.onsmartengineering.com", "port": 5222, "ping": 15, "password": "a32c695ccde9"},
{"username": "DEVICE198", "host": "rolling-stock-sandbox2-openfire.onsmartengineering.com", "port": 5222, "ping": 15, "password": "c93f60d35d51"},
{"username": "DEVICE199", "host": "rolling-stock-sandbox2-openfire.onsmartengineering.com", "port": 5222, "ping": 15, "password": "ddf4d41f846f"},
{"username": "DEVICE200", "host": "rolling-stock-sandbox2-openfire.onsmartengineering.com", "port": 5222, "ping": 15, "password": "07fd03b6fce0"}
]
```

The tool sends regular presence messages (with harcoded dummy versions content)
and properly responds with "unsupported command" to any command sent to it. 


## Usage: 

```./rolling-stock-display-simulation-tool```

## Building
