Bummer to hear that you are having problems using the scripting languages.
Have you looked into the example contained in that repository? https://github.com/exosite-labs/libexositecoap/blob/master/examples/subscribe.c.
You could configure your generic client to use some the aliases is it expects:
command. It should compile and try to reach out to the platform straight away.
With your free account you won't have access to the Provisioning system to setup your own test, so I would recommend doing what the library README says:
If you're planning on testing the included example (make posixsubscribe && ./posixsubscribe) and you're not using the provisioning system you'll need to paste your CIK into a file named
cik to fool the library into thinking that it already activated itself.
You should make this file in the same directory that holds your executable.
Happy to help,
