LED has no function

[NeoTheThird]

Ubuntu 15.04 r7
The RGB LED is off in every case. It would be great if it would indicate charging or notifications anyway but ideally in different colors.

I observe when on charger after battery drain during this permanent rebooting the LED is showing function....

Same here on Meizu Pro 5. No charging or notification led function at all.

FP2 on 15.04 r24

LED does nothing with notifications, but is functional. when running this script:
https://github.com/nfsprodriver/uttweaks/blob/master/disco

the LED indeed displays a disco effect, rotating through all colors.
note: after ending the script with CTRL+Z the led remains on, and on the last displayed color. to shut off the LED, reboot.

Its a permissions problem

@rubencarneiro can you fix it like you did for hammerhead?

[ghost]

change init.qcom.factory.sh
Lines to
chown -h 0666 system.system /sys/class/leds/red/brightness
chown -h 0666 system.system /sys/class/leds/green/brightness
chown -h 0666 system.system /sys/class/leds/blue/brightness
chown -h 0666 system.system /sys/class/leds/red/device/grpfreq
chown -h 0666 system.system /sys/class/leds/red/device/grppwm
chown -h 0666 system.system /sys/class/leds/red/device/blink
chown -h 0666 system.system /sys/class/leds/red/brightness
chown -h 0666 system.system /sys/class/leds/green/brightness
chown -h 0666 system.system /sys/class/leds/blue/brightness
chown -h 0666 system.system /sys/class/leds/red/device/grpfreq
chown -h 0666 system.system /sys/class/leds/red/device/grppwm
chown -h 0666 system.system /sys/class/leds/red/device/blink

that should fix the problem

I add hammerhead label until we have rolled out the fix. Thx Ruben as always for quick response!

https://github.com/nfsprodriver/uttweaks/blob/master/disco

Is there source code somewhere for that binary? TIA...

[nfsprodriver]

disco.zip
The cpp is the source code.

Where is this file: init.qcom.factory.sh ?

IN OTA 2 the FP2 has function :-)
It is blinking green when notifications arrive. Thank you for this :-)

But that’s it. No charging information or other infos signalled. Would be great if charging also will be indicated in the future. As mentioned, when phone is off,charging is indicated with RGB (red if empty, green if full)

[Flohack74]

We will close this for the time being, new features for the led will come up later, but all 3 devices have now notification blinks working. Thats what was the original function provided by Canonical.

[Flohack74]

Please make a more specific new feature request.

[bastos77]

(FP2) LED feature request: Charging notification like already working when phone is switched off. GRB: From red when empty, over yellow when half charged to green when fully loaded.
Interesting is, that this behaviour can already be observed if the phone is shut down. So I see a chance to bridge this feature from ?bios? to the OS
