we are using micro coap as server(to receive the message from client arduino and then to glow a LED) on one of the arduinos with ethernet shield.could someone help us to know what coap can be used as client( to detect the output of LDR and then check if there is any obstacle using IR sensor and send the message to server arduino) so that the two arduinos with ethernet shields can communicate with each other.
What is a "micro coap"?
it is a type of CoAP(protocol that is implemented in C) which can be used only on server side. What should we use on client side?
