3200不运行系统,怎么样自动检测到断网事件

Other Parts Discussed in Thread: CC3200

TI工程师:

          你们好,想请问下3200不运行系统,怎么样自动检测到断网事件,联网事件可以检测的到,但是断网事件无法检测到;没有采用smartconfig联网配置,用的是flash读取密码联网;

那么:(1)是否类似联网事件要清除一个标志位;

(2)是否需要调用某一个专用函数

 

  • CC3200断网的时候会返回一个DISCONNECT的时间,请问你有收到这个世界吗?

  • 检测不到这个事件,这个事件是需要通过调用哪个函数来注册吗?

  • 会产生 SL_WLAN_DISCONNECT_EVENT事件:

    void SimpleLinkWlanEventHandler(SlWlanEvent_t *pWlanEvent)
    {
    if(pWlanEvent == NULL)
    {
    UART_PRINT("Null pointer\n\r");
    LOOP_FOREVER();
    }
    switch(pWlanEvent->Event)
    {

    case SL_WLAN_DISCONNECT_EVENT:
    {
    slWlanConnectAsyncResponse_t* pEventData = NULL;

    CLR_STATUS_BIT(g_ulStatus, STATUS_BIT_CONNECTION);
    CLR_STATUS_BIT(g_ulStatus, STATUS_BIT_IP_AQUIRED);

    pEventData = &pWlanEvent->EventData.STAandP2PModeDisconnected;

    // If the user has initiated 'Disconnect' request,
    //'reason_code' is SL_USER_INITIATED_DISCONNECTION
    if(SL_USER_INITIATED_DISCONNECTION == pEventData->reason_code)
    {
    UART_PRINT("[WLAN EVENT]Device disconnected from the AP: %s, "
    "BSSID: %x:%x:%x:%x:%x:%x on application's "
    "request \n\r",
    g_ucConnectionSSID,g_ucConnectionBSSID[0],
    g_ucConnectionBSSID[1],g_ucConnectionBSSID[2],
    g_ucConnectionBSSID[3],g_ucConnectionBSSID[4],
    g_ucConnectionBSSID[5]);
    }
    else
    {
    UART_PRINT("[WLAN ERROR]Device disconnected from the AP AP: %s, "
    "BSSID: %x:%x:%x:%x:%x:%x on an ERROR..!! \n\r",
    g_ucConnectionSSID,g_ucConnectionBSSID[0],
    g_ucConnectionBSSID[1],g_ucConnectionBSSID[2],
    g_ucConnectionBSSID[3],g_ucConnectionBSSID[4],
    g_ucConnectionBSSID[5]);
    }
    memset(g_ucConnectionSSID,0,sizeof(g_ucConnectionSSID));
    memset(g_ucConnectionBSSID,0,sizeof(g_ucConnectionBSSID));
    }
    break;

  • 你好,

    跑TI的例程。

    打开你的串口,波特率设置为115200..

    连上一个AP,跑起来,然后你再把AP关掉,你看看UART都打印些啥了~
