Wi-Fi in User Mode

[alekz]

Hello everyone,

I'm trying to make a networking application and I think it would be better if it will run in User Mode.

But here is the problem, pspSdkLoadInetModules can be called only from the Kernel Mode. If I don't call it, and call only pspSdkInetInit - it says error 8002013A (LIBRARY_NOT_YET_LINKED).

So, is it possible to use Internet in User Space mode and how? Maybe I have to link the libs via Makefile somehow (static?).

BTW: do I have to call pspSdkInetInit from a new thread or it can be called from the main() function?

Thanks,
Alekz

P.S. I've run through various example codes, forum posts, but haven't found an answer yet - most of the code runs in the Kernel Mode there.

There's a way to do it with a function from sceUtility (sceUtilityLoadNetModule, if I recall correctly). But it only works on firmware 2.0 and higher.

The only sane way I'm aware of to do wifi that works on all firmwares is to use the traditional kernel-mode initialisation technique that you'll find in the samples, and let eLoader automatically translate it into the user-mode version for you when you run it on FW 2.00+.

I just tried it and it works. Instead of the pspSdkLoadInetModules() use the following:

Code: Select all

if &#40;sceUtilityLoadNetModule&#40;PSP_NET_MODULE_COMMON&#41; < 0&#41;
&#123;
  printf&#40;"Error, could not load PSP_NET_MODULE_COMMON\n"&#41;;
  sceKernelSleepThread&#40;&#41;;
&#125;
if &#40;sceUtilityLoadNetModule&#40;PSP_NET_MODULE_INET&#41; < 0&#41;
&#123;
  printf&#40;"Error, could not load PSP_NET_MODULE_INET\n"&#41;;
  sceKernelSleepThread&#40;&#41;;
&#125;

Thanks for the info guys!

I've tried using the sceUtilityLoadNetModule functions - and they didn't return error, so it looks like they work. But, when I call pspSdkInetInit, it again says error 8002013A. I thought maybe sceUtilityLoadNetModule already inits the modules, so I tried to connect to an access point, without the pspSdkInetInit. But it resulted in 8002013A too.

@powARman - did you try it on 2.XX or 1.5 firmware?

[powARman]

I tried it on 271SE-B'', startet from GAME271 directory, so it runs in 2.x mode. I can successfully connect to my access point using WPA, so its definitely 2.x, cause 1.5 does not support WPA.

This is the litte program I used, I build it with "make all" using standard pspsdk Makefile:

Code: Select all

#include <pspkernel.h>
#include <pspdebug.h>
#include <pspsdk.h>
#include <stdlib.h>

hi!

i tryied to make a app with WPA wi-fi user mode support. (on 3.0X OE)
but im fail... this returns false.

look this simple example: http://www.megaupload.com/?d=1ULAWXFC

thanks!
