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?
