Hi, all :
I am going to use RawAPI to send the data between PC to my platform based on ARM. my platform can recieved data form PC now . However , when i try to send data form my platform to PC , it dosen't work ! my code is below :
if(tcp_sndbuf(pcb) < hs->left) {
len = tcp_sndbuf(pcb);
} else {
len = hs->left;
}
do {
err = tcp_write(pcb, hs->file, len, 0);
if(err == ERR_MEM) {
len /= 2;
}
} while(err == ERR_MEM && len > 1);
if(err == ERR_OK) {
hs->file += len;
hs->left -= len;
}
Is it somthing wrong in this code ? Can someone tell me how to send data by RawAPI . Thanks
!
