Hi Clarke, Thank you for pointing me out. This new example is really great. I've also tried almost all old examples before, as well as examples provided with IoTivity sources. But still there is some unclear part for me. All examples shows how to create and handle a device which has server resources (like binary switch). It is pretty clear how to discover, perform on boarding and operate with such device. Of cause there is the client part in the examples as well. But it is rather some abstract client not real one. In the real case, like a smart home, for example, the home network consists not only of server devices but of client device as well. Very basic example: I have a lamp device with has binary switch resource. This lamp is the OCF server device. It can be discovered, provisioned and operated. Then I have a simple switch device (just button) which should control this particular lamp. In order to control the lamp, this switch device should be the OCF client. It doesn't have any resource. This is pure binary switch client in term of OCF. Shall this client populate any OCF resources (like oic.wk.p, oic.wk.d etc.)? It looks like, yes, because it should be discovered and provisioned in order to communicate with other devices in my network. Another question, how to make logical link between the client device and the server device? I mean, how to tell the client (switch) that it should communicate with this particular service (the lamp)?
Unfortunately, I didn't find any explanation of above scenario neither in IoTivity examples nor in OCF spec. Do I miss something in OCF architecture? Or do I have wrong OCF concept understanding? Thanks.
