AM335x: WLAN Multirole problem

Other Parts Discussed in Thread: WL1271

Hello Respective,

I have wl1271 Wireless device on Sitara AM335x starter kit.

I have tried multirole feature by following below link.

http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_NLCP_Multi_Role_Configuration

but its not working in multirole.

I am able to set first mode successfully, that is I can connect wlan0 to my wifi internet router.

Now I have followed steps to start wlan1 as Access point using hostapd.

All steps are followed in the same sequence of reference url: http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_NLCP_Multi_Role_Configuration (section: Scenario 1)

In that sequence, when we reached to run hostapd to make access point and we are getting below messages from hostapd.

Hi Girish,

It appears that your driver is out of date. Downloading the latest SDK should solve the problem.

Hi Victor Lin,

Thanks for quick answer,

I tried with new sdk ti-sdk-am335x-evm-06.00.00.00.

Now the Station mode Asscociation is completed in single shot, but when we try for making AP then it throws error

Girish,

Can you post the hostapd.conf file? The default softAP interface used in the SDK is wlan0, which interferes with your wlan0, which is already set to STA mode.

Hi Victor Lin,

Please find attached 7167.hostapd.cfg hostapd.conf as you asked.

Today, we have tried to check multirole (Station + P2P). Here also same issue, not able to perform multi role.

Steps Performed on EVM1:

MAC EVM1: wlan0 00:18:32:ba:a4:90 and wlan1 00:18:32:ba:a4:91

MAC EVM2: 00:01:33:88:44:74

1. Connected to station using WPA UI default application.

2. Disabled power saver mode by -> iw wlan0 set power_save off

Started continues ping for this interface by Ubuntu host machine to know connectivity while processing below steps.

3. Started wlan1 in managed mode by -> iw wlan0 interface add wlan1 type managed

4. Set wlan1 IP by -> ifconfig wlan1 192.168.3.3 up

5. Started wpa supplcant for P2P -> wpa_supplicant -d -Dnl80211 -c/etc/p2p.conf -iwlan1 -B

Attached 2275.evm1_p2p.cfg

Up to here steps are repeated for EVM2 on wlan0 with different p2p.conf. Attached 5658.evm2_p2p.cfg.

6. Started wpa_cli (On EVM1, I got attached

Conclusion:

We strickly have followed the steps given on OMAP wiki but in that, we are not able to connect wifi with station every time, where else from UI application its get connected easily.

Secondly, we failed to test multirole (Station+AP) or (Station+P2P) by following wiki page steps, please refer above steps and its logs.

P2P in single role working perfectly, but in multirole its not working as expected.
