Hi @dserbu
Now it resolved the conflicting ESP32 coap library and this library on new version.

[dserbu]

Thanks for the quick update, it works now. One more question, is there possible to add also an observer for a resource with this library?

[hirotakaster]

Now this library don't have an Observe, but it will be possible.

[dserbu]

Ok, the initial issue is solved.

[dserbu]

Now this library don't have an Observe, but it will be possible.

Can you give me some suggestions on that. I would like to try it.
