We received the vortex today, thank you for that.

we sadly don't have any device working on IOS, so we can't install and use WhenDo to program the robot.
I installed Scratch 2 on my portable PC, witch has his own bluetooth. I thought I don't need a Bluno wireless adapter, do I ? Vortex appaers connected to the PC in bluetooth, but I didn't manage to program it : I followed all the steps to connect it, but when I open the folder "Vortex example" with scratch2, the small colored circle beside Vortex is red. :(
How can I solve this problem ?
