With latest Compat wireless package (2012-04-034 and firmware Rev 6.3.7.0.105 ) I am able to successfully calibrate and nvs file sucessfully.

However, I am not able to connect to any device. there is crash in the modules. However I am able to do the scan operation successfully.

There is crash after running the following commands

>ifconfig wlan0 192.168.1.6 up

>iw dev wlan0 scan

>iw wlan0 connect Digisol

 

Please find the attached log

    Girish,

    Is Digisol an open or secured AP?

    Girish,

    In the attached log, I don't see you running scan command / iw utility. wlan0 is being configured for ad-hoc mode instead.

    Please run "ifconfig wlan0 up" and "iw wlan0 scan | grep SSID" to see if you can see the networks around. Thanks,

    Saurabh

    I am trying to associate with "Digisol" which is an open AP. When I try to connect, the system crashes

    Thanks

    Girish,

    Try using wpa_cli to connect the the AP and check if you get the same result:

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

    Please upload the complete log - including all the iw / ifconfig / wpa_cli commands. What platform are you working on? Thanks,

    Hi Girish,

    I think we don’t use iwconfig commands for ibbs mode, I think that the 2 commands that we use are as follows:

     iw wlan0 ibss join <SSID>  <freq in MHz> [fixed-freq] [ <fixed bssid>] [key d:0:abcde]

     iw wlan0 ibss leave

    However I will verify that and update that forum

    Regards,

    Eyal

    Hi Girish,

    For more information on the replacement of iwconfig commands, please refer to http://linuxwireless.org/en/users/Documentation/iw/replace-iwconfig (there you can also find the right commands for ibss mode)

    Regards,

    Eyal

    Hi Girish,

    fo IBSS mode please try the Following

    Configure an IBSS mode:

    ifconfig wlan0 downiw dev wlan0 set type ibssifconfig wlan0 up

     

    Create or Join an IBSS network: 

    iw wlan0 ibss join <ssid> <freq># example:iw wlan0 ibss join test 2437

    Create or Join an IBSS network with WEP:

    iw wlan0 ibss join <ssid> <freq> key d:0:<WEP key># example:iw wlan0 ibss join test 2437 key d:0:0123456789

    Leave IBSS network:

    iw wlan0 ibss leave
