WiFi Direct in a WL12xx

Is WiFi Direct supported in the WL12xx firmware today and can be used together with the open source "Linux wireless" system?

So WiFi Direct is not possible today with a WL12xx?

What changes in SDK5.03 will implement WiFi Direct?
Is it only a changed WLAN firmware binary file?

Hi,

I am supporting Anders, and would like to add some precision to the last question.

WiFi Direct seems to be a cluster of features - Discovery (Bonjour or UPnP) , Setup (WPS based on WPA2), Soft AP (Group Owner) and Power Save (via WMM, and new stuff).

The Linux Wireless developers seem to be working on the Application layer for WiFi Direct, but I cannot see much defined yet (http://wireless.kernel.org/en/developers) so the question is basically what functional WIFI Direct features (APIs or application examples) comes with EZSDK v5.03 that can be built on today, and what parts are missing if we have the goal of e.g setting up a direct link to copy a file from one handheld unit to another via a WiFi Direct connection?

Thanks for more details.

Hi ,

The modification for WiFi direct are done in the WPA supplicant (use 0.8x releases) driver and firmware. i just started to write some information on that in our WiKi page, please visit http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_NLCP_WiFi_Direct_Configuration_Scripts

Hello.

I have a confusion with service discovery and p2p invitation feature of wifi direct. Actually when i should apply service discovery command; either finishing device discovery or after forming group ownership. Same thing about p2p invitation. Could anyone please guide me the procedures to follow.

Hi Sujay,

P2p discovery is action to enable the other p2p client to know that you are present, similar to scan operation. Were Invitation action is something different, for example in case a client want to join a p2p network then the Group owner has to invite him in order to allow the client to join p2p group
