BLN support which kernel + ROM? confirm working BLN - Galaxy S 4 General

may i know what kernel and roms combination for i9505 for bln control app to work?

none that i know off
I don't think any .. not really needed when you have a multi colored led light (or even the flash) that you can configure for various notifications.. look at light manager or light flow.. Why would you need bln?

[Q] Difference between CMLed and BLN?

I just flashed Oxygen 2.3.2 (with Oxygen stock kernel) and it has a handy device sub menu where you have some control over back light notification (back light timeout and blinking)
BLN mod is not installed according to the BLN control app, and NStools shows the same. I'd assume this means the mod is not implemented into the kernel.
NSTools does however have a sub menu entitled 'CMLed' which I can acsess (with back light timeout and blinking options, same as in the Oxygen devices menu). And this is what I'm wondering...
Whats the difference between CMLed and BLN? Are they separate implementations of the same idea?
Sorry for the long winded post, hopefully someone can clear this up for me.

I have been wondering the same thing.
BLN is the original backlight notification, made by Neldar.
CMLed was made by Cyanogenmod team not too long ago.
They're pretty much the same in terms of usage though.
So we can customize the blinking and everything with cmled? I'll have to give it a try..

app suggestion .. using back and menu buttons as noticication LED

coming from htc legend and xperia mini, the led notification lights was an important feature, now i really miss it in the note, and using noled app is not the same as having actual led lights.
so i was thinking if there is a possibility to use the menu and back buttons lights as notification light ? i found that they are separate from the screen light .. so can this be done by an app or a custom rom or it can't be done ?
This idea has already been implemented for many Samsung devices. Just find a custom kernel with "BLN" Support (BackLightNotification) and then download the app (info HERE) and away you go.
Hope that helps mate

check bLED
after i posted this i found out about bLED and bln kernel (i didn't know what bln means) thanks for your help
There is also noLED. Not one i use but you might aswell know all the options
I've read that they all hurt battery life
i tried noLED but i didn't like it
i know that bln might drain the battery faster but it's important for me, and maybe with further development some of the current problems might be fixed
NoLed is good, doesn't require root and only uses about 3% battery when enabled (and nothing if you switch it off). You can also customize the settings for additional power saving and I managed to get it down to 1% by setting the notification to flash on and off.
My only issue with NoLed is that from time to time it gives me the sleep of death. Disable it And my issues go away - haven't had time to test whether or not SoD is down to the power saving settings.

How to control keyboard LED on xt720

Hi,
I want to create a script that make keyboard LED blink when there is an sms or a missed call. The problem is I don't know how to control this LED and how to watch for event like sms or missed call.
If someone could help it will be fine.
Thank you
Edit: I found that we can control LED in sys/device/platform/button-backlight ( or something like that ) but when I change brightness to 0 it go back to 125.

I think what you are seeing might be the light sensor resetting the value when automatic brightness mode is enabled. There's a lookup table that sets lcd and button backlight to specific values based on the ambient light reading. So... If you have automatic brightness enabled in settings, try disabling that and see if the behavior changes.

I was thinking about automatic brightness but the goal is to control LED with automatic brightness. Have you an idea to set a value in a script to watch for sms ?

Which ROM are you running? To get that working on CM7 you probably have to modify either the framework or fjfalcon's liblights (but it shouldn't be too bad if you're patient and can search/read code somewhat). IIRC the ledmeknow app will blink the button leds if automatic brightness isn't interfering but I haven't tried that in a long time. One downside is that an app/script that does blinking will keep your kernel awake. (My understanding is that the low-level firmware runs the blinks on the three-leds which allows the kernel to sleep, but driving from an app/script will keep the kernel awake i.e. look for the "blink" file in the same directory as the "brightness" file)

I searched for lights.c in the ROM but couldn't find. More there isn't blink file but that I know is that ledmeknow change brightness value from 0 to 125 to make led blink.
You spoke about framwork can you tell me wich file it is ? I found that : http://forum.xda-developers.com/showthread.php?t=928608 but I don't know if it is the correct file.
Thank you
EDIT : So after few more search I found that I have to edit service.jar (source : http://forum.xda-developers.com/showthread.php?t=1546302)

Can someone tell me which file into service.jar I have to mod ? because now I am abble to open and mod it and I have services.jar from other phones where it work so I want to know which file to compare.

[Q] LED control

I have Droid mini, it has a LED. I want to control it by LightFlow or something, it works. But it seems that the OS is controlling it too, for example when battery is low. Is somewhere a setting, where I can modify OS-level LED behavior? I want to turn it off and only allow LightFlow to do it.
P.S.: any experience with lightflow of other apps of this kind? Are they reliable on Droids?
Thanks
