ESP IDF: Task never leaves vTaskDelay() - c

Question

I am building a system that creates a WLAN AP over which the end user can Connect/disconnect the ESP to another AP ( For example a router) by posting a JSON String to a URL. In APSTA mode. When this is done a bool "_STA_START" is set to true. And the login parameters are saved in _STA_WIFI_SSID and _STA_WIFI_PASS.
I encounter a problem when writing the Task that manages the esp as Station. When the vTaskDelay() is called the code in the vTask_Manage_STA_Connection() just stops running. If I delete the statement. The code runs very fast until it casues a stack overflow and resets the esp.
start_Manage_STA_Connection() is called in main.c after I initialise the esp as Access Point.
Right now I see on the monitor that the loop in the vTask_Manage_STA_Connection runs a single time.
Below you can find my Tasks.c and Task.h
Task.h

#define INCLUDE
#include "config.h"
#endif
#ifndef INCLUDE_WLAN_STA
#define INCLUDE_WLAN_STA
#include "WLAN_STA.h"
#endif
// Dimensions the buffer that the task being created will use as its stack.
// NOTE: This is the number of words the stack will hold, not the number of
// bytes. For example, if each stack item is 32-bits, and this is set to 100,
// then 400 bytes (100 * 32-bits) will be allocated.
#define STACK_SIZE 2048
/// #brief Starts a Task to Manage the STA Connection
/// #param pvParameters
void vTask_Manage_STA_Connection( void * pvParameters );
/// #brief Calls vTask_Manage_STA_Connection in main.c
/// #param
void start_Manage_STA_Connection( void );
Tasks.c
#include "Tasks.h"
static const char *TAG_Manage_STA = "Manage STA Connection";
// Task to be created.
void vTask_Manage_STA_Connection(void *pvParameters)
{
for (;;)
{
// Task code goes here.
if (_STA_START == true)
{
ESP_LOGI(TAG_Manage_STA, "Connecting to Station...");
wifi_init_sta(
_STA_WIFI_SSID,
_STA_WIFI_PASS);
_STA_START = false;
}
ESP_LOGI(TAG_Manage_STA, "Managing STA Connection...");
vTaskDelay(100/portTICK_PERIOD_MS);
}
}
// Function that creates a task.
void start_Manage_STA_Connection(void)
{
static uint8_t ucParameterToPass;
TaskHandle_t xHandle = NULL;
// Create the task pinned to core 0, storing the handle. Note that the passed parameter ucParameterToPass
// must exist for the lifetime of the task, so in this case is declared static. If it was just an
// an automatic stack variable it might no longer exist, or at least have been corrupted, by the time
// the new task attempts to access it.
xTaskCreatePinnedToCore(vTask_Manage_STA_Connection,
"Manage_STA_Connection",
STACK_SIZE,
&ucParameterToPass,
(configMAX_PRIORITIES-1),
&xHandle, 0);
configASSERT(xHandle);
// Use the handle to delete the task.
if (xHandle != NULL)
{
vTaskDelete(xHandle);
}
}
