W5100 sendto 타임 아웃 문의

Question

아래 코드로 구현하여 udp 소켓(2번)생성 후 데이타 전송하는데 타임아웃(BROS_sendto 함수 참조)이 걸리네요 무었때문인지 영문을 모르겠네요… 참고로 ip등 네트웍 설정은 정상으로 r/w됩니다. //mcu-w5100 통신방식: spi 통신 //////////////////////////소켓 생성 루틴///////////////////////////////////// BROS_Ethernet_udp(BROS_UDP_SOCK_NUM, BROS_MY_CONNECT_PORT, BROS_data_buf,0); //udp 소켓 생성 void BROS_Ethernet_udp(BROS_SOCKET s, u16 port, u8* buf, u16 mode) { switch(BROS_getSn_SR(s)){ case BROS_SOCK_UDP: if((BROS_len=BROS_getSn_RX_RSR(s)) > 0){ // check the size of received data //len = BROS_recvfrom(s,buf,len,destip,&destport); //RUI_RecvMessage에서 데이터 취한다 BROS_RecvMessage(s); //if(len !=sendto(s,buf,len,destip,destport)){ // send the data to the destination // printf(“%d : Sendto Fail.len=%d,”,s,len); // printf(“%d.%d.%d.%d(%d)

네트웍 설정에서 서브넷과 게이트웨이 ip가 바뀌었었네요 …
