I’ve been using the Core SDK for several months now and can’t get used to the lack of a way to turn the lights on/off. Especially because the system tray switch for the EyeX also fails. This leads to the absurd procedure of constantly plugging in and out the USB cable.
For me, this functionality is the biggest weakness of the otherwise very nice Core SDK. Hopefully the constant emergence of this topic here in the forum will move Tobii in the right direction.
