RTOS/CC2640R2F: How to trigger the sensor controller task second time when does not use fwScheduleTask()?

sdf chris

Part Number: CC2640R2F

Tool/software: TI-RTOS

I want to control the execution time of sensor controller task, my system does not need to execute the SC task at interval time, When my task over, it will send interrupt to main cpu to stop the rtc tick using scifStopRtcTicks to save power. So I comment the fwScheduleTask(1) in execution code of sensor controller studio. But when I want to trigger the task manually second time, it can not run. The retrigger code is as following:

scifStartRtcTicksNow(0x00010000 / 10);
scifExecuteTasksOnceNbl(BV(SCIF_LED_BLINKER_TASK_ID)); // call thi will return SCIF_ILLEGAL_OPERATION

Hi Chris,

That seems to be okay - not sure if a delay is required between starting up the RTC ticks and reenabling tasks.

I've contacted a sensor controller expert for more information -

I forget I should clear the interrupt source and feed an ack in the interrupt event. Now it works. Thanks.
