Hello i am a new user of lwIP. I am using lwIP-1.2 and porting to AVR ATMega64. Everything is works well when i compiled the example (http server). But when I am starting to make a clien application using lwIP a problem occured. I can not connect the server but when I checked the response everything is fine (tcp_new,tcp_bind,tcp_connect) . I also have checked using Ethereal but there is no data to be sent and tes function is never been called. here is my source code. is there I miss somethong or something wrong in my code ?
