A Field Guide to CoAP, Part 1
The last goal of CoAP is that it is easy to implement. There are protocol implementations in just about every device-side and cloud-side programming language, with libcoap & californium being defacto reference implementations for devices and servers. But there are specific design features in the protocol that make it easy to implement in constrained environments, like how it uses UDP and a compact message format to save on payload size, but we’ll cover those details shortly.

embedded newb, need help including libcoap
If someone could explain how I'm supposed to include the libcoap library, I would be very appreciative. So far I have been able to build the libcoap executables and run them on my linux desktop. I can run the server and the client, and it works fine. However, I can't just run those x86 executables on the arm-based system. I have tried compiling the .so version of the libraries(with gcc for arm), so that I could include that in my .c programs (definitely couldn't get it to work despite using arm-none-eabi-gcc... is this only allowed in c++ programs?). I'm also really confused as to why half of the source files are .c files. For example, there's a coap_openssl.c file that has no main function, and defines a lot of the functions I would like to include. However, I don't seem to be able to connect the dots on how to make this all work cohesively.
