[SDK-2.3.0, BCM943362WCD4]
I have been trying to test the ability of Wiced to maintain a TCP connection across powersaves.
I have effectively merged tcp_client and ping_powersave to create an app that
creates a TCP connection and then sleeps. It wakes every N seconds to send and receive data
down the same connection (i.e. the connection is not destroyed). Its talking to a HTTP 1.1 server (i.e. with keep-alive).
It works, i.e. it wakes and successfully sends and receives data on the same connection.
The trouble is I cant seem to keep the service up for more than a few wakes.
From wireshark the AP does not seem to be deauthing and I can see no connection resets from the server side.
If I enable the connection to be setup and destroyed on every wake (see #define CONNECT_EVERY_TIME) then
the system will stay awake for at least 500 seconds (perhaps a separate issue here).
So it would seem that somehow the TCP state is not being maintained across a sleep, or it is but it loses its mind fairly quickly.
App is attached - just need to provide SSID.
