How do I do this?
"station mode"!

The theory is: the p2p group owner (go) peer behaves pretty much
like an Access Point. Hence, legacy devices  like the rtl81yySx
can connect to it the same way like they would connect to an
accesspoint or router.

No "magic" driver or anything is needed. If you can connect to a
run-of-the-mill protected AP, you can connect to a running wifi-direct
network.

I have downloaded the driver from:

http://www.realtek.com/downloads/downloadsView.aspx?Langid=1&PNid=48&PFid=48&Level=5&Conn=4&DownTypeID=3&GetDown=false&Downloads=true#RTL8188SU

this would also have worked with r8712u or r92su.

Installed and loaded the module 8712u.

"iw list" doesn't list p2p-client or p2p-go.

"station mode" "station mode" and again "station mode".

"station mode" != "p2p-go" or "p2p-client". Just fire up your peer
device and let the driver connect (either via WPA2-PSK or WPS). You
don't need to deal with the console at all, this all can be done
with the push of a GUI button (NetworkManager, wicd, ...).

Remember: Do it like you simply want to connect to your AP.
(no p2p magic!)


We need the "p2p magic" to develop a linux miracast sink.

I followed the thread.
It shows me that it makes no sense. I am a beginner and I only can
spent time for it if someone tells me for example: fill this module with code for this specific function. I have good literature and I think I
can try to help but not lead something.

Hey that's great, that's exactly what needs to be "done". ;-)


I don't know yet if I have the time to take part. But as I wrote I have a good book which describes in detail driver development for 2.6 kernel.

What do you think how many LOC have to been written?

Best regards
p2p
