It is noteworthy that Bluetooth support can be added to a Windows CE system running on Toradex modules, although this is not included in the standard image.
It is a known fact that the backlight is controlled independently from the display driver. But there is one exception to take note of, if the registry settings for backlight GPIO and display GPIO are identical, a change of the backlight will also change the state of the display driver accordingly. Please refer to Display driver registry settings for details. It is important to note that this is applicable only for Colibri PXA Modules. Another noteworthy feature is that on our carrier boards, PWM<A> is used for adjusting LCD brightness.
