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
