LED Meanings

You will see green, blue and red LEDs on the ARK GPS when it is being flashed, and a blinking green LED if it is running properly.

If you see a red LED there is an error and you should check the following:

  • Make sure the flight controller has an SD card installed.

  • Make sure the ARK GPS has ark_can-gps_canbootloader installed prior to flashing ark_can-gps_default.

  • Remove binaries from the root and ufw directories of the SD card and try to build and flash again.
