CC2640R2F: Sensor controller studio example project: Task Control

Hello,

I was running the task control example project from the SCS. The LED fader task is not exactly performing what it has to do. It is making the LED blink at regular intervals instead of variable intervals based on the onDuration and offDuration parameters for the evhSetupTimer1Trigger(0, onDuration, 2); and evhSetupTimer1Trigger(0, offDuration, 2); procedure calls in Event Handler code. 

I executed the example as it is and did not modify. Am I missing something here? 

Regards,

Swarna
