Hello, all.
I heard that Arduino(mega + Wi-Fi Shield) can't get data through multicast.
So I tried to communicate Arduino and Linux(C++ SDK) using unicast.
Below code is that.
Base code is <iotivity>/resource/examples/simpleclient.cpp and
<iotivity>/resource/csdk/stack/samples/arduino/SimpleClientServer/ocserver/ocserver.cpp
Version of Wi-Fi shield is 1.1.
I upgraded it.
1. using findResource function with IP + Port
requestURI << OC_RSRVD_WELL_KNOWN_URI << "?rt=core.light";
OCPlatform::findResource("112.108.39.218:55555", requestURI.str(),
CT_DEFAULT, &foundResource);
std::cout<< "Finding Resource... " <<std::endl;
2. using constructResourceObject function with IP
std::vector<std::string> resourceTypes;
resourceTypes.push_back("core.light");
std::vector<std::string> interfaces;
interfaces.push_back(DEFAULT_INTERFACE);
OCResource::Ptr resource =
OCPlatform::constructResourceObject("coap://112.108.39.218:4097", "/a/light",
CT_DEFAULT, true, resourceTypes, interfaces);
Both code are not working.
First code can find resource, but GET command is not working.
Second is also not working on same part(GET)
I want to know the reason why it is not working.
And How to solve it.
Or the other way to communicate between Arduino(mega + wi-fi) and Others(Linux,
Android)
