We've configured the pin as an input after the device boots. Even with with just a jumper wire between the two pins, an output and an input, the behavior on the black and white is different. Here's how we set it up: sudo sh -c 'echo "60" > /sys/class/gpio/export' sudo sh -c 'echo "117" > /sys/class/gpio/export' sudo sh -c 'echo "in" > /sys/class/gpio/gpio60/direction' sudo sh -c 'echo "in" > /sys/class/gpio/gpio117/direction' sudo sh -c 'echo "falling" > /sys/class/gpio/gpio60/edge' sudo sh -c 'echo "falling" > /sys/class/gpio/gpio117/edge'
