@l2m2k2 Hi, this is just demo software for you to see before exploring with your own sketches! You can view the source code for hints programming it yourself. I would not worry about it!

you could ignore the version notice. just select the core2 device on the setting page will be ok. 1.0.12 was for the Desktop IDE software version. 1.4.5 or 1.6.x was for the UIFlow firmware version. [image: core2_uiflow_selcet.jpg]
