Hi all, I set up the LwIP Stack on two microcontroller and use the raw mode. Now I'm trying to build up a connection and send some data over TCP with static IP. But it doesn't work. I can see the ARP request with wireshark but there is no response. Also the request is send only one time. The strange thing is that I can connect and send some data with putty over a PC. Is there anything special I have to consider when connecting from LwIP to LwIP?
I have enabled TCP, ARP, ICMP and call every 250ms tcp_tmr(), every 5000ms etharp_tmr() also every 1ms a tick is generated for sys_now(). The initialization of the listening pcb is: struct tcp_pcb *receive_pcb; receive_pcb = tcp_new(); tcp_bind(receive_pcb, IP_ADDR_ANY, 4098); receive_pcb = tcp_listen(receive_pcb); tcp_accept(receive_pcb, tcp_accept_connection); The initialization of the active pcb is: struct tcp_pcb *transmit_pcb; struct ip_addr ipAddr_dest; IP4_ADDR(&ipAddr_dest,192,168,0,2); transmit_pcb = tcp_new(); tcp_connect(transmit_pcb, &ipAddr_dest, 4098, tcp_send_data); -- View this message in context: http://lwip.100.n7.nabble.com/LwIP-host-connecting-to-LwIP-client-tp20552.html Sent from the lwip-users mailing list archive at Nabble.com. _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
