Hi,

I have created a task with xEventGroupWaitBits, to set the eventbit i using rtos timer callback function for every 10 sec. But I'm receiving task wdt trigger for every 5 sec.

xTaskCreate(Task, "Data Collector Task", 2048, NULL, configMAX_PRIORITIES, NULL) == pdTRUE;

dataTimer = xTimerCreate("Timer", 10*1000, pdTRUE, (void *)0,(TimerCallbackFunction_t)TimerCallBack);
xTimerStart(dataTimer, 0);
static void Task(void *pvParameters)
{
EventBits_t eventRecieved = 0;

while(1)
{
eventRecieved = xEventGroupWaitBits(dataEvent, Flag, pdTRUE, pdFALSE, portMAX_DELAY);

if((eventRecieved & Flag) == Flag)
{
...........
}
}
}
static void TimerCallBack(TimerHandle_t xTimer)
{
xEventGroupSetBits(dataEvent, Flag);
}

1.How should I avoid this task wdt ?
2. Any other way to handle wdt without deleting it?

Doesn't look like your issue is in the snippet that you posted.

using rtos timer callback function for every 10 sec

You sure about that? That's 10000 OS ticks, i.e. 10000/100=100 seconds with the default tick rate of 100Hz.
