The RR has 3 leds, green(172), blue(174), red(175). All can be programmable.

Below is a small script to flash the green led on RR.

#!/bin/sh

# enable the gpio 172 -> green led
echo 172 > /sys/class/gpio/export

# set the direction to output
echo "out" > /sys/class/gpio/gpio172/direction
while true;
do
echo 0 > /sys/class/gpio/gpio172/value #led on
sleep 1
echo 1 > /sys/class/gpio/gpio172/value #led off
sleep 1
done
