DustProxyExt is the proxy extension used by any Dust proxy point. Each Dust proxy point represents a specific channel in a Mote. Typically, a channel represents some value in a sensor or actuator.
The DustProxyExt has common ProxyExt properties, such as status and enabled. See “ProxyExt properties” in the Drivers Guide for more details.
In addition, the following DustProxyExt properties are unique or have special importance:
-
Mote Id
The ID of the mote in which the channel originates.
-
Channel Id
Channel within the mote (identified by Mote Id) of the point.
-
Sample Time
Server time of the current value.
-
Async Notification
Whether or not the point is currently subscribed to receive values from the notification channel.
This does not mean a subscription with the backend system—it is internal to the client driver only.
