If the app found your Pluto Trigger in the last step, move on to the next step. Otherwise, try turning on your Pluto Trigger's Bluetooth. Press and hold the button on Pluto Trigger for at least 5 seconds. If the status LED blinks three times, then Bluetooth has been turned on. If the status LED blinks only once, then Bluetooth has been turned off. Press and hold again to turn Bluetooth on.
