Hi All, I have a wifi/BT combo module with Marvell's SD8787 dual frequency (2.4GHz and 5GHz) chipset on it. When I try to build a p2p connection with other 5Ghz capable wireless device (Nexus 4), the connection will never be built at 5GHz. Same module I install on a linux-pc platform with kernel version 3.17.1 has no problem to build a 5G p2p connection. The firmware I am using is from the Marvell git repo at git://git.marvell.com/mwifiex-firmware.git Using this latest commit: commit 3f45b8c4cc1eb1d102bc3486b19677332dd215ab Author: Avinash Patil <patila@xxxxxxxxxxx> Date: Fri Sep 12 21:05:15 2014 +0530 linux-firmware: update Marvell SD8787 firmware version p52 Version 14.66.35.p52 Note that this version doesn't support BT-AMP. The image can be downloaded through either WLAN or Bluetooth. Signed-off-by: Avinash Patil <patila@xxxxxxxxxxx> Signed-off-by: Frank Huang <frankh@xxxxxxxxxxx> With iw phy phy0 info, I can see that 5GHz frequency is listed. And I can also use this module to connect a 5G wireless router without problem. The mwifiex driver is from kernel version 3.10.44, which is not allowed to be upgraded to the latest kernel version. I cannot use backports either, due to the 3.10 version. Besides, there is an sdio error occurs very often when a p2p connection is being built: [20525.984188] mwifiex_sdio mmc0:0001:1: 2022598 : Tx timeout(#1), bss_type-num = 2-0 then the p2p connection will be failed to be built with the error: <3>P2P-GROUP-FORMATION-FAILURE <3>P2P-GROUP-REMOVED wlan0 GO reason=FORMATION_FAILED I don't know if this is related to the no-5GHz issue. Any ideas? Thanks!
