LED blinking

Connecting USB

While the controller is establishing a wired connection with the computer all LEDs will blink at once, if the blinking continues forever it means that the controller is not able to connect to the PC.

Potential solutions:

  • Unplug the controller and plug it back in.
  • Try using another USB cable, be sure that the cable is not just a charging cable, and that it supports USB 2+.
  • Check that the computer is not suspended.

Boot warnings

If any problems are detected during boot, the controller LEDs will blink in an alternating horizontal and vertical pattern.

The specific problem will be pointed out in the Firmware logs section on the Ctrl app. Some of these problems could be:

  • The controller is not calibrated yet.
  • One (or both) of the IMU / Gyro(s) could not start, possibly because a problem with soldering.

Double-pressing the Home button will make the LEDs to stop blinking, and ignore there issues until the next boot.
