OPT_CONNECT_TIMEOUT not work

HI all, I use K60 and MQX4.2.

In TCP/IP protocol, K60 as client and computer as server. K60 can receive data and send data every 1 second.

my question is when computer disconnect TCP connection and reconnect after 10 seconds , k60 can't receive data and computer also can't receive data

it means reconnect fail. .

I modify the OPT_CONNECT_TIMEOUT, OPT_SEND_TIMEOUT,OPT_TIMEWAIT_TIMEOUT, but still not work .

this is my code

uint32_t opt_value=TRUE;

uint32_t time_out=10000;

uint32_t send_time_out=10000;

uint32_t wait_time_out=10000;

uint32_t opt_length = sizeof(uint32_t);

sock_list[0]=socket(AF_INET,SOCK_STREAM,0);//创建TCPIPsocket

setsockopt(sock_list[0],SOL_TCP,OPT_SEND_TIMEOUT,&send_time_out,opt_length);

setsockopt(sock_list[0],SOL_TCP,OPT_CONNECT_TIMEOUT,&time_out,opt_length);

setsockopt(sock_list[0],SOL_TCP,OPT_TIMEWAIT_TIMEOUT,&wait_time_out,opt_length);

laddr.sin_family=AF_INET;

laddr.sin_port=8000;

laddr.sin_addr.s_addr=INADDR_ANY;

bind(sock_list[0],&laddr,sizeof(laddr));//绑定TCPsocket；

raddr.sin_family=AF_INET;

raddr.sin_port=8000;

raddr.sin_addr.s_addr=IPADDR(192,168,50,200);

setsockopt(sock_list[0],SOL_TCP,OPT_RECEIVE_NOWAIT,&opt_value, opt_length);

connect(sock_list[0],(struct sockaddr *)&raddr,rlen);

while(1)

{

RTCS_selectall(100);

recv(sock_list[0],buffer_tcp_recv,30,0);

send(sock_list[0],buffer_tcp_send,16,0);

if (buffer_tcp_send[9]==0x03)

_time_delay(1000);

}

为何bind()？

Hi,

Please check the below threads and let me know if this helps!!

RTCS Connect

OPT_CONNECT_TIMEOUT not working as expected?

RTCS TCP server socket doesn't accept the connection after disconnecting client 2 times

Have a great day,
Sol
