Releasing the LEDs to system control
During a Python interactive session, or from within a Python script, you can release control of the LED
from Python to system control using the led.release() method.
If the Python script or session terminatesprior to releasing control to the system, the LEDs will
continue to have the state that Python set to them, until the device isrebooted. See Configure scripts
to run automatically for information about configuring the device so that the LEDstate iscontrolled
by the Python script even after reboot.
If any system processesattempt to take control of the LEDwhile Python is in control of it, the state
information from the system processisrecorded but the LED state is not updated until Python
releases control of the LED. When the LEDis returned to system control, the state of the LEDwill
reflect the correct, recorded state information.
