CC3220SF-LAUNCHXL: Event 0xffff87fd

Here the complete structure I've just received:

SlDeviceEvent_t
  id = 7
  Data
    Error
      Source = SL_DEVICE_SOURCE_OTHER
      Code = -30727 (0xffff87f9)
    ResetRequest
      Status = 0
      Caller = 34809 

In which document are explained the meanings of these values?

It's slightly different from the previous, but both have to be defined and documented somewhere.

It's not "my" callback, it's "yours" :-) In the OTA Cloud example:

void SimpleLinkWlanEventHandler(SlWlanEvent_t *pWlanEvent)
{
    SlWlanEventData_u *pWlanEventData = NULL;

    if (NULL == pWlanEvent) return;

    pWlanEventData = &pWlanEvent->Data;

    switch(pWlanEvent->Id)
    {
        case SL_WLAN_EVENT_CONNECT:
        {
            UART_PRINT(2, "STA connected to AP %s, ", pWlanEvent->Data.Connect.SsidName);

            UART_PRINT(2, "BSSID is %02x:%02x:%02x:%02x:%02x:%02x\r\n",
                    pWlanEvent->Data.Connect.Bssid[0],
                    pWlanEvent->Data.Connect.Bssid[1],
                    pWlanEvent->Data.Connect.Bssid[2],
                    pWlanEvent->Data.Connect.Bssid[3],
                    pWlanEvent->Data.Connect.Bssid[4],
                    pWlanEvent->Data.Connect.Bssid[5]);

            SignalEvent(APP_EVENT_CONNECTED);
        }
        break;

        case SL_WLAN_EVENT_DISCONNECT:
        {
            SlWlanEventDisconnect_t *pDiscntEvtData = NULL;
            pDiscntEvtData = &pWlanEventData->Disconnect;

            /** If the user has initiated 'Disconnect' request, 'ReasonCode'
              * is SL_USER_INITIATED_DISCONNECTION
              */
            if(SL_WLAN_DISCONNECT_USER_INITIATED == pDiscntEvtData->ReasonCode)
            {
                UART_PRINT(2, "Device disconnected from the AP on request\r\n");
            }
            else
            {
                UART_PRINT(2, "Device disconnected from the AP on an ERROR %d\r\n", pDiscntEvtData->ReasonCode);
            }

            SignalEvent(APP_EVENT_DISCONNECT);
        }
        break;

        default:
        {
            UART_PRINT(2, "Unexpected WLAN event with Id [0x%x]\r\n", pWlanEvent->Id);
            SignalEvent(APP_EVENT_ERROR);
        }
        break;
    }
}

You're right, sorry. I mixed up the two things because I also received a non-documented wlan error (in the other thread).

But this doesn't change the question: where is defined and what does that mean?
