RD is a feature that's designed for servers that know they want to be represented by one. Basically, the design goal is for low-power devices to not need to stay on and listen for (or respond to) discovery multicasts; rather they register themselves with RD which will answer those on its behalf, and can go to sleep waiting for something that will directly ping them. So you could twist them into a presence-like behavior but it wasn't meant for that. _______________________________________________ iotivity-dev mailing list iotivity-dev@lists.iotivity.org https://lists.iotivity.org/mailman/listinfo/iotivity-dev
