12.3.6 Defined tree structure
The tree structure of the IoT Core interface is divided into various substructures.
These include information about the device, functions for updating the device firmware and the IoT
core interface.
The
nodes
structure is offered as an additional substructure. It builds up a separate substructure for
each connected VWV00x sensor.
Structure:
[ip address]:8001
Substructure
Description
[ip address]:8001
../deviceinfo
Information about the device
../firmware
Information and update of the device firmware
../iotCore
Information and update of the IoT Core interface
