== CoAP Client == * Contribution consists of CoAP client ** Supports PUT/GET/POST/DELETE *** Not yet FETCH/PATCH (RFC 8132) ** Supports Blockwise transfer ** Supports Notification (QCoapReply::notified signal, QCoapClient::cancelObserve()) ** Partially supports multicast *** Sending on multicast works and works for receiving one reply *** Currently does not work with receiving multiple replies * API is modelled after QNAM but does not use it ** QCoapClient, QCoapRequest, QCoapReply * No DTLS support yet (see network discussion) * API does support IETF-style resource discovery (multicast GET to /.well- known/core) ** QCoapClient::discover, QCoapDiscoveryReply ** API needs a little work: *** signal and parameters *** discover() should be able to send on both IPv4 and v6 multicast, without the user hardcoding anything *** building of query parameters (QUrlQuery?) * Add a method to QCoapClient and QNetworkAccessManager: setDeleteOnFinished / setAutoDeleteReplies ** Defaults to false on QNAM, defauts to true here * No CoAP+TCP plans yet
=== Testing === * Once we have CoAP server support, we can test client against server * Inadviseable to run a CoAP server on the Qt network test server ** Network too unstable already in TCP, probably a horrible idea to use it with UDP * We should run a local server on the testing VM ** Californium is Java ** We may need to write something with libcoap (C) == CoAP server == We will need it. For example, ''all'' OCF devices are both clients and servers. == DTLS == * DTLS support needs to be added to QtNetwork or it will be too difficult ** We just need to design it so that it will work for both the CoAP client and server == CBOR == We would like to have CBOR support in QtCore. * Would the API be part of QJsonDocument or separate (but looking like it)? ** Thiago's gut feeling is that making it part of QJsonDocument will make it too constrained for future uses (Example: COSE uses integer keys in maps, not strings) * Volunteers to work with Thiago on doing this ** Witekio people ** Frederik ** Shawn ** Alexandro -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list [email protected] http://lists.qt-project.org/mailman/listinfo/development
