We can control the blue LED with the trigger node in sysfs. But the red LED is hard-wired to the power input rail and we can't control it.
Turn off
su - echo none > /sys/class/leds/blue\:heartbeat/trigger
Turn on
su - echo deafult-on > /sys/class/leds/blue\:heartbeat/trigger
Hearbeat (original state)
su - echo heartbeat > /sys/class/leds/blue\:heartbeat/trigger
There are many other trigger modes. But some of them may not work.
cat /sys/class/leds/blue\:heartbeat/trigger
If you want to turn the LED off automatically in boot process,
edit /etc/rc.local file to add “echo none > /sys/class/leds/blue\:heartbeat/trigger”.
edit /etc/rc.local file to add “echo none > /sys/class/leds/blue\:heartbeat/trigger”.
