But there can be a delay between reporting and reprogramming, and if during that time a new event could be reported? I guess it doesn't matter much if we assume that upon reprogramming the driver will always report a new event if the current value falls outside the new range (either high or low)... it just seemed a little bit more consistent to unconditionally report a new event at the beginning, even if that new event is "yup - falling into the middle of your range now". johannes
