By convention, all tasks created by a sample application or associated helper modules have a priority higher or equal to 50.

When using the Helper Modules, the following tasks are created:

As a results, the tasks created by the sample applications have a priority higher or equal to 53.

By convention, the name, priority and stack size associated with each task of a sample application are defined in a header file called app_task_cfg.h.

For example, the following contents indicates that the sample application defines 3 tasks. called "disco", "mgrconn" and "uart":

#ifndef APP_TASK_CFG_H
#define APP_TASK_CFG_H
 
#define TASK_APP_DISCO_NAME         "disco"
#define TASK_APP_DISCO_PRIORITY     55
#define TASK_APP_DISCO_STK_SIZE     256
 
#define TASK_APP_MGRCONN_NAME       "mgrconn"
#define TASK_APP_MGRCONN_PRIORITY   54
#define TASK_APP_MGRCONN_STK_SIZE   256
 
#define TASK_APP_UART_NAME          "uart"
#define TASK_APP_UART_PRIORITY      53
#define TASK_APP_UART_STK_SIZE      256
 
#endif

Here stack sizes are given in 4-byte words, so a stack size of 256 words = 1024 bytes of memory.  A total of 8 kB of memory is set aside for all user tasks.
