How can I recover from a network outage? I leave the cable from my system to the network switch connected, but pull the cable from the network switch to the cloud. Detecting that the server I was talking to is no longer talking is easy
enough, but how do I recover? I’m using a plain old socket to make the connection, and lwIP_send/lwIP_recv) for data transfer of an HTTPS GET request.
I start up a timer that expires if there is no server response after a minute; much more than enough, I’m told. But what then? Can the timer callback do anything to make lwIP_send or lwIP_recv return to the calling task, preferably with
an error?
