Problem with Multi_Role_Configuration!

Dear TI Expert!

I want to config Multi_Role for WL183x : wlan0 as station connected to internet and wlan1 as AP and permit the device connected to wlan1 AP can internet access but I facing the problem below:

Scenario1: I followed this link: http://processors.wiki.ti.com/index.php/OMAP_Wireless_Connectivity_NLCP_Multi_Role_Configuration, scenario "Surf the Web", 

I can access to internet from device connected to wlan1 but in the short time the system warning error and auto reset, please see the log below:

root@am335x-evm:/home# wlan1: STA d0:57:85:6a:2b:db IEEE 802.11: authenticated

wlan1: STA d0:57:85:6a:2b:db IEEE 802.11: associated (aid 1)

Scenario2: I followed this link:http://processors.wiki.ti.com/index.php/WiLink8_WLAN_Demo:_Linux#AP_.28create_AP_with_no_security.29,  but I cannot 

access to internet from device which connected to wlan1.

Scenario3: I splitted 2 difference scripts for enable Station and AP: when I run wifi Station script first then I cannot enable wlan1 by script. Please see 

the log below:

    Hi Tri,

    Please follow the instructions from: processors.wiki.ti.com/.../WiLink8_WLAN_Demo:_Linux to check multirole scenario

    Dear Gigi!

    I had tried your link before but I cannot access to internet from device which associated to wlan1 while wlan0 already connected to internet AP.
    This link below is ok:
    processors.wiki.ti.com/.../OMAP_Wireless_Connectivity_NLCP_Multi_Role_Configuration
    But the problem is after active wlan0 as Station and wlan1 as AP, the system often auto restart in several minutes without reason.

    Another problem I observed is: if the wlan1 AP already active and I running enable wlan1 AP script again then the wlan1 warning error as log below:
    /etc/udhcpc.d/50default: Adding DNS 208.91.112.53
    Configuration file: /etc/hostapd.conf
    [ 151.732843] wlcore: down
    nl80211: Failed to set interface wlan1 into AP mode
    nl80211 driver initialization failed.

    if I shutdown wlan1 by "ifconfig wlan1 down" and then running enable wlan1 AP script again then the result the same above.
    Please advise!
    If in our application we want to have the On/Off wifi button so how we can On and Off the wifi repeatedly without error?

    Thanks and Best Regards,
    Tri.

    Hi,

    Can you please explain the "auto restart" ? What is it? Can you share the logs?
    Also, you can ignore the - "wlcore: WARNING no fw rx ba on tid 3". This is just a warning.

    Regarding: "if the wlan1 AP already active and I running enable wlan1 AP script again then the wlan1 warning error as log below" - this is expected as the interface is already up.

    "if I shutdown wlan1 by "ifconfig wlan1 down" and then running enable wlan1 AP script again then the result the same above." - this is NOT expected.

    My recommendation is to use a few seconds delay between the wpa_cli commands and see if it helps.

    Regards,
    Gigi Joseph.

    Below are wifi_AP.sh script to avtive wlan1 as AP:

    echo Enabling wifi AP
    iw phy0 interface add wlan1 type managed
    ifconfig wlan1 10.4.30.34 netmask 255.255.255.0 up

    echo 1 > /proc/sys/net/ipv4/ip_forward
    udhcpd /etc/udhcpd.conf
    iptables -t nat -A POSTROUTING -o wlan1 -j MASQUERADE

    Please explain this error!
    If I want to turn On and Off wlan1 AP many time without need reset system so what should i do?

    Thanks and Regards,
    Tri.

    Hi Tri,

    You cannot do: "iw phy0 interface add wlan1 type managed" every time.
    It is only required the first time.

    "ifconfig wlan1 down" will not remove the interface.

    So second time when you run the "wifi_AP.sh" script, what is failing is the "interface add" command because wlan1 is already present.

    Regards,
    Gigi Joseph.

    Dear Gigi!

    I tried bring up wlan1 again ignored step "iw phy0 interface add wlan1 type managed" followed your advice but the have the error at step run hostapd "hostapd -B /etc/hostapd.conf -P /var/run/hostapd.pid" and the wlan1 was not created AP again, please see the log below:

    Hi Tri,

    Why is there an "ifconfig up" command before running the script? The hostapd will bring up the interface (mentioned in hostapd.conf file)
    Please ensure that you make the script in accordance with the AP Demo page at: processors.wiki.ti.com/.../WiLink8_WLAN_Demo:_Linux

    Regards,
    Gigi Joseph.

    Dear Gigi!

    What should I do to enalbe wifi AP again, I did followed AP Demo page but after shutdown wlan1 I cannot create wifi AP again.

    I realized that the command "hostapd -B /etc/hostapd.conf -P /var/run/hostapd.pid" cannot run many time, if it already run one time, module will have error if I run this command again.

    Please advise!

    Thanks and Best Regards,

    Tri.

    Hi Tri,

    Yes, you cannot run multiple instances of hostapd. You need to kill and restart it.

    Gigi Joseph.
