[lwip-users] UDP send ok but Can't find in Ethereal

[the_gadfly]

hi:
this is my code,modified form stand-alone lwip example web server. I am
trying to send messages through UDP. But all it is sending are ARP's.

Could anyone tell me what's wrong?

Best Regards

if(err==ERR_OK)
printf("send ok !  \n");





}
