Hi,
Recently I want to get Backlight brightness (Or at least, light on or off) because I want to add an Indicator to identify whether the backlight has been turned on.
The purpose is, for Edge device, at the day time, we CANNOT easily see whether backlight on or off. So I want to show an Indicator on my DataField so we can easily read whether backlight on so can turn off that manually to save battery.
Is that any way to get the information? (Just get. I know we CANNOT set)
Thanks for your kindly help.
