This takes the code up to the latest released version of libcoap. As there have been API changes, coap_client and coap_server in examples/protocols have been updated to use the new APIs. Further information on the new libcoap APIs can be found at https://libcoap.net/doc/reference/4.2.0/ coap_client has been updated to handle BLOCK2 responses from "coap://californium.eclipse.org" coap_client has been modified to only send out one request (and wait for the response) coap_server has been updated to support Observe subscriptions, and well as adding in PUT and DELETE handlers to work on the Espressif resource coap_server and coap_client have had their stack sizes increased. port/coap_io.c has been added, a copy of libcoap/src/coap_io.c with support added for systems that do not have RFC 3542 section 20 support. port/coap_io_socket.c has been removed as a lot of the code is now replicated in different libcoap files. Once this PR is place, then adding in DTLS will be a lot simpler (as a separate PR) Signed-off-by: Jitin George <jitin@espressif.com> Merges https://github.com/espressif/esp-idf/pull/3148 |
