So I just got my own cortex and a joystick, but I am having troubles pairing them. I followed all of the instructions on the pamphlet they give you, but instead of 2 pairs of solid green Robot and Vexnet lights, it never moves past solid vexnet and blipping robot on joystick, and blipping robot and fast blinking game on the cortex. I have let it go for up to 4 minutes. When I try interrupting it and just trying the vexnet keys, it doesn’t work. Please help.
