JavaScript SystemInfo Service API (WRT 1.1)

This SystemInfo Service API is supported since WRT 1.1.

The SystemInfo Service API allows widgets to access and modify system information on a device. The API is integrated into WRT through the device object.

For an overview of the service and the API, see section Accessing and modifying system information.

Using the SystemInfo Service API

To use the SystemInfo Service API, your widget must first create a service object for it using the device.getServiceObject() method. Use Service.SysInfo to identify the service provider and ISysInfo to identify the supported interface:

var so = device.getServiceObject("Service.SysInfo", "ISysInfo");

This service object can then be used to access the services provided by the API:
