CC3200 Getting Started with WLAN Station project is not connecting PC to LaunchPad

Other Parts Discussed in Thread: CC3200

I have the same issue as Vinu Gopalakrishnan he posted in January 2015 regarding CC3200 Getting Started with WLAN Station project.

I also followed all steps described in CC3200-Getting_Started_Guide, made changes in common.h and still connection between LaunchPad board and PC will not be established.

I traced the CC3200 code in IAR IDE. The firmware enters WlanConnect() function, executes sl_WlanConnect() and then is looping forever where it is toggling red LED. It looks like it is waiting for IP from the PC but is not getting it?

Thanks,

    Hi Steven,

    Can you please give more details? Do you know if the CC3200 connects to the Access Point (SSID mentioned in common.h)? Is the PC also connected to the same AP? Have you given the correct AP security in common.h?

    Regards,
    Gigi Joseph.

    Hi Gigi,

    1. My first try was with unchanged common.h and it did not work.
    2. My PC is on home WiFi network
    3. These are my original defines in common.h which did not work:

    #define SSID_NAME "cc3200demo" /* AP SSID */
    #define SECURITY_TYPE SL_SEC_TYPE_OPEN /* Security type (OPEN or WEP or WPA*/
    #define SECURITY_KEY "" /* Password of the secured AP */

    What is the right way to modify those defines. It is not clear from the User's Guide swru376b?

    Thanks,
    Steven.

    Hi Steven,

    You have to provide the details of the home WiFi network in common.h. For example, if I want to connect to an AP with name "SSID", having "WPA2" security type with password as "1234567890", I would use the below:

    ***
    #define SSID_NAME "SSID" /* AP SSID */
    #define SECURITY_TYPE SL_SEC_TYPE_WPA_WPA2/* Security type (OPEN or WEP or WPA*/
    #define SECURITY_KEY "1234567890" /* Password of the secured AP */
    ***

    Regards,
    Gigi Joseph.

    Thanks again,
