Hi, I'm using lwip 1.3.2 in an audio stream client application. I close my application like this:
static void httpclient_connection_close(struct tcp_pcb *tpcb, struct httpclient * hc ) { if (hc->pcb) { tcp_arg(hc->pcb, NULL); tcp_sent(hc->pcb, NULL); tcp_recv(hc->pcb, NULL); tcp_poll(hc->pcb, NULL,0); tcp_err(hc->pcb, NULL); if( tcp_close(hc->pcb) != ERR_OK ) { tcp_abort(hc->pcb); } } if(hc) { mem_free(hc); } } Everytime I want to close the connection and open a new one the old connection is not close and and the old pcb state is in fin_wait_2 and stays there. I waited for more that 5 mins but it didnt close. I can see on wireshark that both connections are still open, as if the first connection is still streaming. When I call tcp_close() lwip sends fin and the servers ack it. But the server never sends fin and continues sending data. Are there any precautions that I need to do before closing a tcp stream connection? trex -- View this message in context: http://old.nabble.com/problem-closing-a-stream-tp33517666p33517666.html Sent from the lwip-users mailing list archive at Nabble.com. _______________________________________________ lwip-users mailing list lwip-users@nongnu.org https://lists.nongnu.org/mailman/listinfo/lwip-users
