Title: CoAP client Description: A simple CoAP server showing how to retrieve information from a resource. This demo assumes that the platform of choice has networking support, some adjustments to the configuration may be needed. This sample will make a GET request with path 'test' to the IPv6 multicast address reserved for CoAP nodes, so the URI can be represented as: coap://[ff02::fd]:5683/test -------------------------------------------------------------------------------- Building and Running Project: This project will print all the octets of the response received, more context can be obtained by using a tool like tcpdump or wireshark. See the net-tools[1] project for more details. It can be built and executed on QEMU as follows: make qemu [1] net-tools: https://gerrit.zephyrproject.org/r/gitweb?p=net-tools.git;a=tree -------------------------------------------------------------------------------- Troubleshooting: Problems caused by out-dated project information can be addressed by issuing one of the following commands then rebuilding the project: make clean # discard results of previous builds # but keep existing configuration info or make pristine # discard results of previous builds # and restore pre-defined configuration info ------------------------------------------------------------------------------- Sample output: reply: 60 00 00 00 00 24 11 40 fe 80 00 00 00 00 00 00 5c 25 e2 ff fe 15 01 01 fe 80 00 00 00 00 00 00 5c 25 e2 ff fe 15 01 01 16 33 16 33 00 24 3d 86 60 40 00 01 ff 54 79 70 65 3a 20 30 0a 43 6f 64 65 3a 20 31 0a 4d 49 44 3a 20 31 0a (76 bytes)
