Hi guys,
I am using lwIP code for transfer data via Ethernet with MCU-LPC4357 (use kit MCB4300 of Keil).
My project use LPC4357 is Client and must send data to Server PC.
My problem, i can not send one package with length > 4KByte.
My send data function same:
tcp_sent(pcb_client, client_sent);
ret_val = tcp_write(pcb_client, data, 4096, 0);
if (ret_val != ERR_OK)
{
while(1);
}
It can success send about 4package to Server and then go to while (1).
I know that can change the parameters in opt.h file but really, i don't know how to change?
when i use send package with length 2KByte then always success
tcp_sent(pcb_client, client_sent);
ret_val = tcp_write(pcb_client, data, 2048, 0);
Please help me?
Thank you!
