Hi All

     I'm running WiLink_Driver_6.1.0.0.144(murata wifi module and driver source code)  with 24M clock on my dm365 board.

      STRFRefClock =4 for I use 38.4M XTAL. But when I run wlan_cu, it is hard to find any access point even though I put it close to the AP.

    Hi,

    Murata has external clock source therfore since you used 38,4Mhz then please use STRFRefClock = 2

    setting it to 4 might cause the issue you see.

    Please try it and let me know.

    Thanks,

    Eyal

    Hi,

       Our board has been changed  which used another 38.4Mhz clock for Wifi Module. So STRFRefClock = 4 is the right one I think.

    Hi,

    did you try STRFRefClock = 2 ?

    I suggest trying that before continue the investigation.

    Regards,

    Eyal

    Hi Eyal

           I have tried STRFRefClock = 2, it is the same.

    Hi Iynn,

    Since there is an issue to connect to the supplicant (SW integration issue) from the following log:

    2\# ./wlan_cu
    ERROR - IpcWpa_Sockets_Open - can't connect the socket
    ******************************************************
    Connection to supplicant failed
    ******************************************************

     

    Can you try running without supplicant and connect to non secured AP?

    The way to start the driver with no security is by running ./wlan_cu –b (with –b option) and then try to scan and connect to non secured AP using the CLI.

    Regards,

    Eyal

    Hi Eyal

       I run./wlan_cu –b, and get the same result. It still can't get AP.

    Hi Eyal

         I have change my inductor's value,now it can find and connect to AP.But another question followed now that the connection will lost and reconnect frequently:

    Hi Lynn,

    there are 2 stages here, first to verify if the issue you see is releated to 802.11n mode or not.

    can you please set the AP to work in bg mode only and try to conenct and ping to it?

    if there is no issue with bg mode, then i would like to understand the 802.11n configuration. can you please send the AP configuration? in addition which AP model are you workin with.

    in case you have a wlan sniffer so please capture that and send me the log, from the sniffer i will get the info i need by inspecting the AP beacon.

    BTW what is the inductor's value that you modified? which then it started working.

    Regards,

    Eyal

    Hi Lynn,

    in addition, can you please send me the log of the calibration process? i would like to verify that it is successful

    Hi Eyal

        My wifi module works at BG module(dot11NetworkType = 3 ); unfortunatly the AP can't set work mode which print "b/g/n" in the box.

       Murata didn't tell me how to calibate it, so I did this follow this:http://processors.wiki.ti.com/index.php/Android_wireless_build_and_porting_guide#WLAN_Calibration;

    The log  as below:

    Hi Lynn,

    that is odd since the Station shows error messages ERROR:RxQueue_ReceivePacket: BA event - ADDBA frame for ... that is the station receives ADDBA Action frames from the AP which means that the AP is configured to work in n mode.

    can you try verifying that and set the AP to bg mode?

    Thanks,

    Hi Eyal

          Thanks for your help.

            I'm sorry there is no option to change the AP's mode on their manage web pages.

          Any way, I'm testing the AM1808 EVM now. It can connect to the same AP ,too. But  there are two questions about it:

    1) I ping the AP with AM1808's wlan mode, it just print:

    root@am180x-evm:~# ping 192.168.1.1
    PING 192.168.1.1 (192.168.1.1): 56 data bytes

    64 bytes from 192.168.1.1: seq=4 ttl=64 time=2.715 ms

    u see,there is no ":TIWLAN: 1108.520636: RxQueue                 , ERROR:RxQueue_ReceivePacket: BA event - ADDBA frame for TID already established, TID = 0." was printed.

    Is there any differences between LSR's wlan module and Murata's wLan module？

    2）The AM1808's log shows that it will lost and reconnect to the AP,too.  But my own wlan board is much more frequently. why?

    TI__Genius 9240 points

    Hi,

    LSR iuses internal clock source of 38.4Mhz TCXO and it need to be configured to STRFRefClock = 2

    were Murata uses external clock source of 19.2Mhz, 26Mhz, 38.4Mhz TCXO and it need to configured to:

    STRFRefClock = 0 for  19.2MHz;

    STRFRefClock = 1  for 26MHz;

    STRFRefClock = 2 for 38.4MHz

    Regards,

    Eyal

    Hi Eyal

         We use the external clock of 38.4Mhz for Murata module, and  set STRFRefClock = 4.
