Question

osPriorityNone used in STM32WB example projects

Hello,

Looking at the HRS FreeRTOS example applications code for STM32WB55, I see several task configured with osPriorityNone as priority.

This priority level is defined as meaning 'no priority, not initialized' in cmsis header.

Why is it used here ? How are the tasks supposed to run if they don't have priority ? Does that in effect act as a very high or very low priority ?

Regards.
