Simple Network connection

Are you sure your computer is actually connecting? I know I've had trouble before with connect exiting before it actually connects. Then it seems like it connects, but it really doesn't, leaving your wii without anything to connect to.
Make sure your connect function on your PC server looks something like this:

if(listen(mySocket,1)!=SOCKET_ERROR){	//Listen and wait for incoming connections, 1 backlog
	newConnection = accept(mySocket,NULL,NULL);
        
        // Your Code Here
}

You shouldn't be checking if net_connect returns -1 for failure, you should be checking if it returns <0. Libogc's networking functions return error status directly rather than setting errno and returning -1.

im still not having any luck with getting the wii to connect to my server app. ive used the same for a windows console app (with some exceptions WINSOCK shit) but all in all its the same code, and the windows code connects, but the wii version wont. it says it connects, no errors or anything, but the server app doesnt acknowledge that there was a connection.

ok, it somewhat works now. i run it in the dolphin emu and now it says 'error connecting' and says 'connected' on the real wii but the server pc app still doesnt seem to acknowledge that a connection was made. might be the server app though. will have to take a look at the code for that. thanks for the info for the wii stuff though.

if_config() returns those values for you.

Something like :

char            localip[16];
char            gateway[16];
char            netmask[16];

if (if_config ( localip, netmask, gateway, TRUE) < 0)
{
  // Error
  return;
}

printf("My local IP is %s, the netmask is %s and the gateway is %s\n",localip, netmask, gateway);

burningman — Sun, 14 Nov 2010 14:21:04 +0100

i took a look at that code. i added the if_config(), but i was curious, do i pass it the localip and such or does it return those values. i might have missed it but i didnt see anything that would return the localip and such.

Take a look at the client stub from WiiRadio. We wrote it to work on Linux, Windows and Wii so there are ifdef's. It seems to work pretty well.

[code.google.com]

Edit -

P.S.

On Wii before any network stuff you need to call if_config(). Unless it's been changed recently.

put the connect part in a while loop until it connects

can we see the code?

Re: Simple Network connection

burningman — Sat, 13 Nov 2010 03:37:53 +0100

would there need to be any changes to the code to compile it, say with the c++ compiler? i have some example code for bsd sockets, but for some reason it always says it connects to the ip address i give it even if i dont have a program on the other computer to accept a connection. the code i have is for c not c++, but it compiles fine, but doesnt seem to work.

Re: Simple Network connection

Also check this old thread out. [forum.wiibrew.org]

The Wii's network functions are listed in it. Weird I remembered that thread but the search could not find it.

Re: Simple Network connection

g_man — Fri, 12 Nov 2010 19:28:48 +0100

Read up on bsd sockets. It is the exact same thing as the wii sockets. By looking at your code, you don't know them. Once you can make a few socket examples on your pc then the only difference is all of the wii functions add net_ to the beginning of the function name.

Re: Simple Network connection

burningman — Fri, 12 Nov 2010 19:15:08 +0100

the only thing i changed in the http.c/h files was added the function declares as well as a typedef for boolean as it is used but wasnt declared in the code

i understand that, but the problem that i have with using that code right now, is that it givews me the following error:

linking ... template.elf
main.o: In function `main':
main.cpp:(.text.main+0x450): undefined reference to `tcp_connect(char*, unsigned short)'
collect2: ld returned 1 exit status
make[1]: *** [/d/template/template.elf] Error 1

the only function im using right now is the tcp_connect, just to test to see if it would work.

it works almost exactly the same as bsd sockets. Look up those and then try writing your code.

Re: Simple Network connection

I havent written any code myself. ive had some experience using similar class functions like send and recv in realbasic (OOP style coding similar to C/C++ with classes and such). but none of the wii netcode i have found (not very much) has not been in any form usable (at least by me). i had tried including the WiiNetwork code (link for it on WiiBrew Dev Tools List), but it doesnt want to compile, says things are undefined when they are in the include file and such. theres no sample with that so its hard to see what exactly i need to do to get it up and running. unless ive missed something, which i may have, im stumped. if you or anyone could even help with using that code, it would be MUCH appreciated.

Hi, i was wondering if someone could help me with this. only thing i really need, is a simple class to initilize a connect TO a server. i took a look at the sockettest example, and its very confusing to read as theres not many comments or explainations for whats bieng done. the example works, but the wii app waits for a connection FROM another device, but i want to connect TO another device. i more or less understand how to use the net_send/net_recv functions, but its the setting up of the connect im having trouble.
