Wifi MultiTest .02

http://aibohack.com/psp/wifitest.htm#DEV
I've updated my WiFi test program. The WiFi multi-test program serves several purposes - basic WiFi access, how to connect to other Sony devices; a generally useful PSP program and sample source code.
I've split this into two topics, for people who only want to run the program, and for developers who want to write code based on the sceNetINet sockets-like layer.
This thread is for developers using the source code.
For discussion of the binary program (as a user) including WiFi connect woes, please post on this thread: http://forums.ps2dev.org/viewtopic.php?t=2542

Yes, the DHCP limitation is still there (hard coded IP addresses still required - no DHCP)
The picker will only list non-DHCP connections (so the user can't pick an unsupported configuration). If you have none it will complain. If you have only one, it will automatically pick it. If you have two or more (up to 5) it will let you pick the one you want to use.
Now uses the PSPSDK (version 522 or later required). The initial release of the PSPSDK will not work.
FWIW: Historical topics (some related to WiFi, others related to library loading and patching) can be found on the sceNet/sceHttp thread:

Wifi MultiTest .02 - updated WiFi sample code
need some help
this app is nice, but iam having a small problem, how do i config my IP from the "upsend" app you gave us, do we have to config this in the "slideshow", if so how do i change the info on there cause it wont let you type in the cmd, ----> help please, thanx Rest05
> My question is, why is the DHCP limitation there?
The system already supports DHCP.
This is a limitation in the current sample (reverse engineered from games that do similar but different things). It will take some research and experimentation to figure out what is missing (probably a callback or some other flag bits).

> how do i config my IP from the UDPSEND app you gave us, do we have to config this in the "slideshow"
These are command line tools (start a Windows command prompt first)
The udpsend program takes the IP address of the PSP as the first argument on the command line.
The "slideshow.bat" is a simple batch file for illustration purposes. Change the IP address in the batch file (10.0.1.101) to the address of your PSP. Add more interesting JPG files too.

Is it just me, or does the photo frame not work properly? I've found that it only works with images < 1400 bytes or so, and even then it distorts the image. It isn't the udpsend program, as I tried writing my own and it still fails to display images properly, if at all. I'm using the pre-built 1.50 version; any ideas?
I'm having problems making this work using the latest PSPSDK. The precompiled app works fine, but the one I compile gets stuck on the Pick Connection screen.
I have a similar problem with the previous wifi example, except that it works fine if I don't use PSPSDK. I adapted it to use the sdk and everything works up to the sceNetApctlGetState loop, where it never gets the state 4.
Have you tried it with the latest sdk?
Thanks.

BSD sockets don't belong in libc. Besides, can't you essentially doholger wrote:Is anybody working on incorporating the sceNet* stubs into the SDK and wrapping them with newlib/psplibc sockets?

Re: Wifi MultiTest .02 - updated WiFi sample code
I believe this should properly done by the <machine/socketcall.h> file, included by newlib-1.13.0/newlib/libc/sys/linux/socket.c, don't you think?mrbrown wrote:BSD sockets don't belong in libc. Besides, can't you essentially do?Code: Select all

Do you mean making them all aliases? If the arguments match up exactly, then yeah, that should work. Beware that SCE could've renamed them because they take the same arguments but have different semantics. Or it could've just been overkill :).
I dunno, shoving them into libc just seems messy to me, but it is relatively painless. I'd say, go for it :).

Old question:
> Is it just me, or does the photo frame not work properly? I've found that it only works with images < 1400 bytes or so, and even then it distorts the image
Try the sample images (one sample is 28KB) - http://www.aibohack.com/psp/wifi_photo_samples.zip
There is a minor bug in the JPEG->RGB->Screen code. It doesn't handle 32 bit alignment properly. If the original image X dimension is a multiple of 4 it should work (no distortion). Full screen width is recommended for other reasons.
=======
> I'm having problems making this work using the latest PSPSDK.
I haven't built it recently, but it was working up until now.
If you have a reproducable case (where the binary works and the rebuilt binary does not) please send me an email.
=======
> Is anybody working on incorporating the sceNet* stubs into the SDK
A few people have mentioned it. I haven't bothered since it requires a lot of non-trivial code, not simply stubs (thunk trickery and semi-sample code - most wrapped in the 'nlh.cpp' file)
Also to provide a more complete example including connection picking and timeouts etc -- requires making a fat example with helper libraries (generally against the rules of PSPSDK samples)
BUT there is no reason to wait for PSPSDK support (you can do it now):
If you have an existing program that uses sockets, you can adapt it using this sample and helpers like "#define recv sceNetInetRecv".
It is a close approximation, but not perfect. When it works, it can save a lot of time.
HOWEVER, it is unlikely that the PSP socket implementation (sceNetInet) is perfectly compatible with your existing Berkeley sockets code.
[some things like "setsockopt" for timeouts simply do not work]

hello,
would anyone be so kind an translate udpsend code to something understandable
for unix/bsd (or point how to do it)
the orignal is win only, (pasted below)
thanks,
wojciech

udpsend translated to java
Here is a very simple version of PspPet's udpsend code writen in java.
Instructions
1)Install Java Platform from http://java.sun.com/javase/downloads/index.htm.
2)Copy code to text file named udpsend.java and insert the IP address and jpg location in the code.
3)Use an IDE (Integrated Development Environment) like Dr Java to compile and run the code. Or you can do it through the command line.
Note: I have noticed that the first the program is run nothing happens. You may have to run program more then once to get the image to display on the PSP.
