  The specified interval is only a suggested interval between sensor measurements. You will get at least one sensor measurement within the interval you specify, but the actual interval between sensor measurements can be affected by other applications and the system. To reduce the system overhead, it is recommended to set the longest interval that you can, because the system usually chooses the shortest interval among all intervals specified.

  The specified interval is only a suggested interval between sensor measurements. You will get at least one sensor measurement within the interval you specify, but the actual interval between sensor measurements can be affected by other applications and the system. To reduce the system overhead, it is recommended to set the longest interval that you can, because the system usually chooses the shortest interval among all intervals specified.
