<div><div><div>Hello Dan,Arend and Jouni,</div><div><br></div><div>Thank you very much for taking time for looking into the issue.</div><div><br></div><div>It seems getting P2P work on my Think-pad little difficult. </div>
<div>We were facing the same issue on Raspberry PI board. Hence I started P2P debugging on the ubuntu X86 machine ( think-pad). However when we check "iw list" result on raspberry pi the P2P clinent and P2P Go Rx/Tx frame are supported but in the interface supported list it was not mentioned.</div>
<div><br></div><div>I am attaching user story and necessary logs for Raspberry PI to get help in resolving this issue. </div><div>Request all you to check the below details and suggest me, what could be the root cause.Your help is greatly appreciated in resolving this issue.</div>
<div>----------------------------------------------------------------------------------------------------------------------------</div><div><br></div><div>User Story :</div><div>----------------</div><div><br></div><div>We want to try out WI-FI Display functionality. Just to try out things we have a Raspberry PI as a sink with a USB wifi dongle !</div>
<div><br></div><div>We have Nexus S which has wifi-direct available and Nexus 7 ( no inbuilt wifi-direct, but using third party app called "wifi-direct" from the playstore) as source /server.</div><div><br></div>
<div>We have to try this out with and without device being connected to an AP. </div><div><br></div><div>In the first instance we just want to connect and transfer some data between these two devices. Once that is achieved we want to move further to wifi-display. We have compiled the WPA_SUPPLICANT with P2P support on raspberry PI ( ARM - Broadcom). </div>
<div><br></div><div><br></div><div>Logs and other details:</div><div>------------------------------</div><div><br></div><div>When we run p2p_find from wpa_cli it returns instantaneous FAIL message. </div><div><br></div><div>

</div></div>iwlagn did get support for p2p (landed 2011-07-23, commit c6baf7fb,<br>
kernel v3.2), but it requires a firmware update to ucode API level 6 for<br>
the 1000 devices. Without dmesg output of the driver loading to see<br>
what ucode revision he's got, it's hard to know whether the firmware<br>
supports it or not. Plus, given he mentioned kernel 3.0, it's unlikely<br>
that his kernel has the right support unless it was backported by<br>
Canonical.<br>
