OICMiddle was written to
* be part of a demonstration of OIC Yocto capability,
* act as an example of resource callbacks using class methods,
* provide a simple promiscuous resource editor for examining OIC systems, and
* act as a starting code base for further exploration of OIC capabilities.
As a demonstration, it runs on an Minnowboard running a Yocto-built OS, acting
as a gateway between an Android device (acting as an OIC client) and an
Edison board (acting as an OIC server) with sensors and actuators.
As an example of resource callbacks, it shows a method of using class methods
as callbacks, a critical capability not shown in any of the examples in
iotivity/resource/examples.
As a promiscuous resource editor, it can find, get, put and observe any
resource using a simple command-line interface using the system console.
As a code base, the command-line editor can be the basis for adding additional
editing capabilities, like the additions of various filters.
Running OICMiddle with no arguments on a console shows the various capabilities
it offers. The most important are:
-client. Act as an OIC client.
-console. Accept command lines from console input to drive the OIC client.
-server. Advertise resources found by the OIC client as OIC resources.
The -server capabilites might be the basis for a gateway.
Typing 'help' (or invalid commands) to the console gives a console usage
message. The important ones are:
find Find all resources. Also performed automatically at startup.
show Show the found resources and an assigned index.
get Get the value(s) of the resource with the given index.
put Put one or more resource values for the given index.
