control sensor controller task

Hello Chongchun Moon,

What do you mean, when the CM3 goes to idle or when the entire chip goes into standby? Why do you want to do this?

The sensor controller task can run in parallel independently from the main application processor. In section "3.3.3 Use Power_registerNotify() to register for appropriate power event notifications" in Power Management for CC26xx SimpleLink Wireless MCUs it is explained how to register callback functions for power transition events. In theory it could be possible to start the task in such a callback. But notification callback functions should be minimal functions, in which the driver performs just the necessary steps for a particular power transition, and then returns as quickly as possible. It might be risky to call other functions such as scifStartTasksNbl within this callback in time critical applications. If you explain what you are trying to achieve maybe we can help you reach your goal somehow.

You can stop and start the sensor controller tasks:

scifStopTasksNbl //Stop task

scifWaitOnNbl // Wait for the task to stop. (in certain cases you need to add additional delay)

scifResetTaskStructs // Reset all the task structures

scifStartTasksNbl // Start task
