Observable resource

Hi all! I would try to add an observable resource to my microCoap_server but, there is already a way to do that in RIOT? Thanks all,

Hi, Microcoap does not offer OBSERVE resource type. Use libcoap instead or add it to the current microcoap implementation. You may use Soletta Project, they have OBSERVE capability but it's heavy package, might need to port only required stuff from the package.
