I want a bit further and gained root and ssh access to my device (https://www.mobileread.com/forums/sh...d.php?t=325185)

find provided me with the following result:

Code:

~ # find -iname "bright*"
./sys/devices/platform/tps61161_bl/brightness
./sys/devices/platform/leds-sunxi/leds/power_led/brightness

cat gave

Code:

~ # cat ./sys/devices/platform/leds-sunxi/leds/power_led/brightness
1
~ # cat ./sys/devices/platform/tps61161_bl/brightness
33

sending

Code:

echo 0 > ./sys/devices/platform/leds-sunxi/leds/power_led/brightness
echo 1 > ./sys/devices/platform/leds-sunxi/leds/power_led/brightness

switches the power led off and on, as expected

Code:

~ # echo 28 > ./sys/devices/platform/tps61161_bl/brightness

dims the light. When it is dark I have to find the best value. So far it seems as if the reading light turns of at "27", but maybe I just don't see it.
