Hi all,

- from error number I can assume that it is related to http server. but how to solve this ?

    Hi Bhargav,

    Error -2170 is SL_ERROR_WLAN_PROVISIONING_ABORT_HTTP_SERVER_DISABLED (from errors.h). You can either add a sl_NetAppStart() command before you start provisioning to be sure the internal HTTP server is enabled, or you can use UniFlash ImageCreator to flash the device with an image that has HTTP server enabled.

    Best regards,

    Hello Sarah,

    Thanks for your responce.

    As per your response, I have added  sl_NetAppStart() API before starting the provisioning, the code I modified is as below :

    In function 'ProvisioningExample()'  in file cloud_ota.c

        retVal = sl_NetAppStart(SL_NETAPP_HTTP_SERVER_ID | SL_NETAPP_DHCP_SERVER_ID);
        if(retVal < 0)
        {
            UART_PRINT(" Netapp start error, num:%d\r\n",retVal);
        }
        /* start provisioning */
        retVal =
            sl_WlanProvisioning(provisioningCmd, ROLE_STA,
            PROVISIONING_INACTIVITY_TIMEOUT,NULL,0);

        if(retVal < 0)
        {
            UART_PRINT(" Provisioning Command Error, num:%d\r\n",retVal);
        }

    Then starting the debug session, I am getting the following error :

    Hi Bhargav,

    Can you try setting only the HTTP server? DHCP is available in AP mode.

    Best regards,
