Re: (N900) Possible to change the colour of the notification light???

I'm not sure. It's probably being constrained by the fremantle hildon-toolbar in the name of finger-friendliness.

Re: (N900) Possible to change the colour of the notification light???

Ahh..gotcha. Is there any way to override that for just one particular app?

Re: (N900) Possible to change the colour of the notification light???

first question. what if you have missed a call, and got an im for example..

could it blink green and red through each other for example? red, off, green, off, red, off etc

furthermore, could someone post a '1-post guide' for an entire n00b with all the steps to change the led notification for calls/ims/sms/emails ? i know i actually should try to figure it all out by myself instead of asking someone this.. but.. asking wont hurt anyone i hope :)

Re: (N900) Possible to change the colour of the notification light???

cant find an editor for mce.ini.

cant open as root.

i think more people than just me want this?

I won't say no, but I haven't seen a way just yet.

Currently there are only a limited number of led patterns:

Code:

PatternError=0;5;0;r;9d8040007f007f0040ff7f007f000000;9d800000

PatternDeviceOn=254;0;0;rgb;9d804000422043207f100000;9d800000

PatternDeviceSoftOff=253;0;0;rg;9d804000423f433f7f100000;9d800000

PatternPowerOn=9;3;0;rgb;9d80400042ff02ffc000;9d800000

PatternPowerOff=10;3;0;rgb;9d80400001ff43ff7f007f00c000;9d800000

PatternCommunicationCall=30;1;0;b;9d80400002ff03ff02ff03ff71080000;9d800000

PatternCommunicationIM=30;1;0;b;9d80400002ff03ff02ff03ff71080000;9d800000

PatternCommunicationSMS=30;1;0;b;9d80400002ff03ff02ff03ff71080000;9d800000

PatternCommunicationEmail=30;1;0;b;9d80400002ff03ff02ff03ff71080000;9d800000

PatternCommonNotification=30;1;0;b;9d80400002ff03ff02ff03ff71080000;9d800000

PatternWebcamActive=20;1;0;r;9d80400004ffc0000000;9d800000

PatternBatteryCharging=50;4;0;rg;9d804000427f0d7f7f007f0042000000;9d800000

PatternBatteryFull=40;4;0;g;9d80407f0000;9d800000

Adding new patterns to the list would be easy enough - but getting other applications to use them would be more tough.

I'll see if I can help out shortly - can't guarantee anything today, though.
First off, you'll need to ignore practically everything we've said to Munky - he's using an n810.

Re: (N900) Possible to change the colour of the notification light???

proposing an app for this would be done in brainstorm wouldnt it?

Re: (N900) Possible to change the colour of the notification light???

Some handyman could really make app for this one.

Or could someone help me how to access that mce.ini file and change those values? What apps do I need?

Re: (N900) Possible to change the colour of the notification light???

To do this you need some stuff that needs disclaimers and warnings all over the place, as stated before, it's should be very easy to brick your device using and changing any of these apps/repositories/files,...

First you need root access on xterminal
You can get this by installing rootsh from extras/devel IIRC. (help on this topic in other treads on this forum!)

Then you need a program to edit the file
I like to use leafpad as I'm used to notepad on windows.
Leafpad is also in one of the extras repositories.

Now for the real work:
Open Xterm
type:

Code:

root

from now on you have root access (notice the # at the end of the current line instead of the $) so don't do stupid things!

For safety measures copy the mce.ini file.
how I go about this is by making a directory in the same one the file is in and then copy the file to that directory. To do that:

Code:

cd /etc/mce/

mkdir MceIniOld

cp mce.ini MceIniOld/mce.ini.old

Now open the file with leafpad

Code:

leafpad /etc/mce/mce.ini

and make the changes you'd like to make. Double check your input before choosing save from the statusbar menu! Close Leafpad.

To get the changes you made they have to be reloaded. Force this with this command in xterm as root:

Code:

killall mce

This way you don't have to restart after every change.

Offtopic:
Have to say I learned all this from trailing this forum and great community, makes my N900 experience one of the best yet in phones as well as computer.

Hint:
Googling "linux commands" can teach allot about how to do things the linux way from xterm. move, rename, list content, the use of flags (eg.: -a) and mutch more.
Some general rules: spaces Capitals and symbols matter!!!
One last disclaimer: All in this post I found out by trial and, thankfully very little, error. I don't have a clue about Linux so don't thake this as the right way to do things!!

If you kill/stop the mce process more than (rough estimate) 4 times in approx 2 minutes the service doesn't restart.
You're best off using something like

Code:

initctl stop mce; sleep 2; initctl start mce

because it gives feedback - so will tell you if it hasn't been able to start or stop it.

I've also put a guide to the n900 led patterns here in case anyone wants to play around further with colours etc.

Re: (N900) Possible to change the colour of the notification light???

And a useful script for testing led patterns without having to receive sms/email:

Code:

#!/bin/sh

pattern=PatternCommunicationSMS

dbus-send --system --type=method_call --dest=com.nokia.mce /com/nokia/mce/request com.nokia.mce.request.req_led_pattern_activate string:$pattern

sleep 10

dbus-send --system --type=method_call --dest=com.nokia.mce /com/nokia/mce/request com.nokia.mce.request.req_led_pattern_deactivate string:$pattern

which will activate the sms pattern, let it run for 10 seconds and then deactivate it.

i seriously need help.. i did the kill mce before a read your post but i did your instructions to start the mce again. i rebooted and now my phone doesnt have any light notifications.. any suggestions?

Re: (N900) Possible to change the colour of the notification light???

On reboot mce should start again.
You can check to see if it's running by typing:

Code:

ps | grep mce

Iget the following output

Code:

  741 root      5312 S <  /sbin/mce --force-syslog 

 1750 user      2092 R    grep mce

which shows mce is running.

If mce is running then it might be that some changes you've made have done wrong.
If it isn't then you should be able to restart mce by typing

Code:

rootsh initctl start mce

Let us know what happens.

feel free to help.

It looks like there's quite a bit of cross-over with this.

Re: (N900) Possible to change the colour of the notification light???

Working off of codeMonkey's comments, I've added new patterns to my N900 and used them in new scripts. A few things to keep in mind in adding a new pattern to the N900:

Be sure to add the pattern to the LEDPatterns in mce.ini. Also, be sure to add the LED pattern to the [LEDPatternLystiRX51] section. Initially, it wasn't clear to me which section to use.

Finally, using the dbus commands that codeMonkey provided you can add your new patterns to any application you are creating or modifying.

For more details, check out my recent blog post about controlling the status LED on the N900

Code:

[LEDPatternNJoyRX44]

# Please prefix pattern names with Pattern to avoid name space clashes

#

# Priority (0 - highest, 255 - lowest)

# ScreenOn - 0 only show pattern when the display is off

#      yy determines the increment/decrement steps

#         00-7f -- increment steps 00 = 0 steps, 7f = 127 steps

#         80-ff -- decrement steps 80 = 0 steps, ff = 127 steps

The explaination in the upper part corresponds to the lines below. The bold part seems to be for the color:

Code:

# R-channel pattern in NJoy format (16 commands at most)

# G-channel pattern in NJoy format (16 commands at most)

# B-channel pattern in NJoy format (16 commands at most)

This means the underlined part:

Code:

PatternCommunicationCall=30;1;0;0000;0000;40007f00017f017f050001ff01ff0000

Call is also blue on the N810, right? This is because we have 0000 for Red, 0000 for Green and 'something' for Blue.

You could search for patterns with red ('PatternError') or green ('PatternBatteryFull') and copy the underlined part I mentioned above responsible for the color from the pattern with the color you want to the pattern you wish to change. Do not copy the other parts of the line as they determine rythm and priority and you only want to change the color! This way you should be able to change the colors.

This should do what you want, although I am giving no warranties whatsoever. It is the whole 'Pattern' block, changed call to red, chat to green. Not sure, though, why green is so short:

Be REALLY careful! I am really, really not being nasty here, but maybe you should not edit the file.

Here is the most NOOB question ever here? Plz where do i copy and paste those stuff (Not joking RELLy dnt know!)??

Re: (N900) Possible to change the colour of the notification light???

plzz where do i copy & paste those codes??! Really DONT know at all :D?

Re: (N900) Possible to change the colour of the notification light???

you dont copy it just open mce with leafpad and change them manually its rather simple reread the thread and youll get it

Just a comment; the specific post you quote is for the N810 and not for the N900.

If you want to experiment in your N900 and you don't mind possibly reflashing your device if something goes wrong, you can try the Led pattern editor application.

Re: (N900) Possible to change the colour of the notification light???

can i just tweak in it(changing colours graphically mainly) & just restart the phone and ignore the warnings and copying and pasting % those stuff cuz i aint understand any of them!...so nothing will happen if so?!?!
