Timing Problem when using Event Group and Timers

@SaktiPadhy

but you said that this is not correct in the previous posts (This was resolving my Issue).

I did not say that it was not correct. I said that your explanation was incorrect. More specifically, when you set xClearOnExit to pdTRUE, only the bits you are waiting for get cleared. And therefore, the following line in your previous explanation is incorrect -

@SaktiPadhy

I think the problem was when 50ms Task Event Group bit was read then It will clear the 20ms Task Event Group bit as well.

When you set xClearOnExit to pdTRUE, your clearBitCount variable is expected to increase. The reason that you see it increased only half the time is because your task is running slow and is not calling xEventGroupWaitBits enough number of times. It should be easy to verify by removing the delay loops from the task. If it is determined, it is a CPU performance issue as I suggested before.
