Subject: | [lwip-users] Example for connection-oriented use |
Date: | Mon, 10 Dec 2007 16:41:27 +0100 |
I’d like to use lwIP in a connection-oriented
style but somehow I can’t figure out how to get it working. At the moment my application is based on the lwIP
example of FreeRTOS.org. This is how the connection is handled: listen ->
accept -> process -> close -> listen. I tried to prevent the close of the connection by commenting
out the netconn_close() at the end of the package processing and
netconn_delete() before it goes back to netconn_accept(). Unfortunately I
somehow can only process the first received packet and following packages don’t
seem to reach the application. Although the close of the connection worked OK so far
I need to speed up the communication because the tcp handshake takes up nearly
half of the time for sending and receiving a message to/from the controller. Regards Matthias |
