WIFI signal problem

Other Parts Discussed in Thread: CC3200, UNIFLASH

Dear all,

  I configure the cc3200 as AP mode, and run the example getting_started_with_wlan_ap.  I can see the log echo in the PC, but when use phone to Search for signal of the cc3200,  i can 't find the Wireless hotspot.

   In the same way, I configure 3200 as STATION mode(run the example getting_started_with_wlan_station), it can't connect to my home router,(PS: configure the right SSID and password , encryption)

Thanks & Regards

  • Hi,

        Have you tested the out of box demo with your smart phone?

  • Hi Jking,

    Can you please share the console log in both cases to help us understand the issue?

    If you are running the examples in debug mode using CCS and IAR can you check whether the application gets stuck at any point?

  • Hi Jking,

    Were you able to resolve the issue on your setup?

  • Hi Ankur,

       I'm sorry so long to reply you.

       I have resolved the issue, but i don't know the reason.  I just reinstalled the system and then it is OK. There has a new question , cc3200 is OK before,  but now the system can't run.  it stops at the  function sl_start(), (the same program before). Is the cc3200 broken?

    Reqrds,

    Jking

  • Hi JKing,

    • Can you please share the exact function at which its gets stuck? Can you also share the call stack when its stuck?
    • Are you able to format and update the service pack using the uniflash?

  • Hi Anku,

    lMode = sl_Start(0, 0, 0);  //it gets stuck here all the time
    ASSERT_ON_ERROR(__LINE__, lMode);

    // Get the device's version-information
    ucConfigOpt = SL_DEVICE_GENERAL_VERSION;
    ucConfigLen = sizeof(ver);UART_PRINT("configure simlelink to defaultstate --\r\n");
    lRetVal = sl_DevGet(SL_DEVICE_GENERAL_CONFIGURATION, &ucConfigOpt,
    &ucConfigLen, (unsigned char *)(&ver));
    ASSERT_ON_ERROR(__LINE__, lRetVal);

    UART_PRINT("Host Driver Version: %s\n\r",SL_DRIVER_VERSION);
    UART_PRINT("Build Version %d.%d.%d.%d.31.%d.%d.%d.%d.%d.%d.%d.%d\n\r",
    ver.NwpVersion[0],ver.NwpVersion[1],ver.NwpVersion[2],ver.NwpVersion[3],
    ver.ChipFwAndPhyVersion.FwVersion[0],ver.ChipFwAndPhyVersion.FwVersion[1],
    ver.ChipFwAndPhyVersion.FwVersion[2],ver.ChipFwAndPhyVersion.FwVersion[3],
    ver.ChipFwAndPhyVersion.PhyVersion[0],ver.ChipFwAndPhyVersion.PhyVersion[1],
    ver.ChipFwAndPhyVersion.PhyVersion[2],ver.ChipFwAndPhyVersion.PhyVersion[3]);

    I am sorry ,i don't know how to share the call stack when it stuck.

    I have updated the service pack(servicepack_0.5.2.0.1.bin) using the uniflash!

    Regqrds,

  • Hi Ankur,

        I bought the new board of cc3200.  I found that when i used the new cc3200 and download the same program, it runs well.   Does it mean that my old cc3200 is broken?

    Thank u & Regards,

    JKing

  • If you are able to format and update the service pack on you board then the board should be fine.

    Few points:

    • You should manually reset the board between debug sessions.
    • You need to make sure 'Secure' and 'Alert' options are unchecked while formatting the CC3200.
    • Can you try the 'blinky' example from CC3200 SDK?

    Are you using the CCS or IAR?
