LAUNCHXL-CC3235SF: 数据发送失败后的处理

您好，

1.有没有考虑过内存溢出的情况

在sl_Close()函数逐步调试一下，查看有没有堆栈溢出的情况

您先判断一下，我们再定位其他原因

2.您的代码是否改动？如果未改动，请将例程路径说一下；如果改动，麻烦您把代码贴上来，感谢您的配合。这将更好的解决问题。

您好，整个工程的base是network_terminal这个demo。

其中做了几处修改：

1）在network_terminal.c的mainThread函数中，做了如下修改：

/* Display Network Terminal API commands */
showAvailableCmd();

//connect network.
RetVal = networkConnect();

Semaphore_Params sema_sampletimer_Params_daq;
Semaphore_Params_init(&sema_sampletimer_Params_daq);
Semaphore_construct(&sema_sampletimer_struct_daq, 1, &sema_sampletimer_Params_daq);
sema_sampletimer_Handle_daq = Semaphore_handle(&sema_sampletimer_struct_daq);

//Create DAQ task.
Task_Params task_daq_params;
Task_Params_init(&task_daq_params);
task_daq_params.stackSize = DAQTASKSTACKSIZE;
task_daq_params.stack = &task_daq_rx_Stack;
task_daq_params.priority = 1;
Task_construct(&task_daq_Struct, (Task_FuncPtr)task_daq_Send_Fxn, &task_daq_params, NULL);

Timer_Handle Sample_Timer_handle_DAQ;
Timer_Params Sample_Timer_params_DAQ;

// Initialize Timer parameters
Timer_Params_init(&Sample_Timer_params_DAQ);
Sample_Timer_params_DAQ.periodUnits = Timer_PERIOD_HZ;
Sample_Timer_params_DAQ.period = 2000;
Sample_Timer_params_DAQ.timerMode = Timer_CONTINUOUS_CALLBACK;
Sample_Timer_params_DAQ.timerCallback = Sample_Timer_Callback_DAQ;

Sample_Timer_handle_DAQ = Timer_open(CONFIG_TIMER_2, &Sample_Timer_params_DAQ);
if (Sample_Timer_handle_DAQ == NULL)
{
// Timer_open() failed
while (1);
}

int32_t begin_DAQ;
begin_DAQ = Timer_start(Sample_Timer_handle_DAQ);
if (begin_DAQ == Timer_STATUS_ERROR)
{
while (1);
}

/*
* Calling UART handling method which serves as the application main loop.
* Note that this function doesn't return.
*/
/*
RetVal = cmd_prompt(NULL);

if(RetVal)
{
while(1)
{
;
}
}
*/


return(0);

}

此外，在文件中追加了以下两个函数：

void Sample_Timer_Callback_DAQ(Timer_Handle myHandle, int_fast16_t send)
{
int ret = 0;

Semaphore_post(sema_sampletimer_Handle_daq);

if(errFlg == 0)
{
count1++;

if(count1==10)
{
count2=10;
count1 = 0;
}
}
else
{
ret = sl_WlanDisconnect();
gSocket = Connect_to_PC();

errFlg = 0;

}
}

void task_daq_Send_Fxn(UArg arg0, UArg arg1)
{
UInt32 time1, time2;
int ret = -1;

gSocket = Connect_to_PC();

for(;;)
{
if(errFlg == 0)
{
if(count2==10)
{
int32_t sock = 0 ,st;
app_CB.gDataBuffer.nwData[3]++;

time1 = Clock_getTicks();
st = Send_UDP_Data_to_PC(gSocket);
if(st < 0)
{
errFlg = 1;
UART_PRINT("\n\r errFlg : %d \n\r ", errFlg);

}


sendtimes++;
if(sendtimes > 10)
{
errFlg = 1;
UART_PRINT("\n\r sendtimes > 10 %d \n\r", sendtimes);
}


time2 = Clock_getTicks();
if(app_CB.gDataBuffer.nwData[3]==255)
{
app_CB.gDataBuffer.nwData[2]++;
}
count2=0;
}
}
}

}

其中，networkConnect()函数就是网络连接，

Connect_to_PC()函数是连接UDP，Send_UDP_Data_to_PC(gSocket)就是调用sl_SendTo()进行数据发送，

这三个函数是我自己提取出来的，主要功能与Demo本身没什么变化，就不提供了。

麻烦帮忙看一下，谢谢。
