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.
