Dear Sir:
I find a very strange question.
I use Luminary LM3S8962,and I use the Lwip1.2.0 ported by Luminary.
I define The max tcp connection is 4
the pbuf size is 256 and the pbuf number is 32
But I find a very strange question for each connection I can receive 9
package of less the 512 bytes more than 256 bytes and 18 package of l
less than 256 bytes ,then no receive at all . If the 4 connection is all
used , It can receive nothing from the Lwip Tcp.
Can someone give me answers ? and why ? and how to solve this question .
The source show like this
static err_t my_recv(void *arg, struct tcp_pcb *pcb, struct pbuf *p,
err_t err )
{
char *rq;
INT16U i;
if(p != NULL)
{
rq = p->payload;
....
pbuf_free(p);
com1_led_on();
}
return ERR_OK;
}
static err_t my_accept(void *arg, struct tcp_pcb *pcb, err_t err)
{
tcp_recv(pcb, my_recv);
return ERR_OK;
}
void monitor_init( void)
{
struct tcp_pcb *pcb;
monitor.ornt_state=0;
pcb = tcp_new();
tcp_bind(pcb, IP_ADDR_ANY, 23);
pcb = tcp_listen(pcb);
tcp_accept(pcb,my_accept);
}
