Task Priorities

Task	Prio	Changeable	Description
LED Control	2	yes	Controls LED blink sequence
NVM_APP_WriteAsyncTask	3	yes	Asyncronous write to non-volatile memory
SMI UART Task	7	yes	UART Tool communication interface
Application	9	yes	User Application
IOLM Stack	25	yes*	Stack State machines (cyclic communication and handling app reqs)

Note: The IOLM Stack task is handling cyclic exchange and processing of appliation requests. Stack callbacks are called from this thread and should not block. The thread is doing often short processing and should be at high prio.
