I am playing with the basic-emac-uip-webserver-project example based on uIP. It seems to be a perfect demonstration, but what I can not do is initiate a communication from the board. If I need to send a message not in response to a request from the client, but, for example as a timer-triggered event, where should i place uip_send() request? All my attempts gave me no results- the uip_send() call is always ignored. Thanks!
