How to use led? (Fremantle/Qt 4.6)
 

Hi,

I would like to make led blink in my app, couldn't find any examples or documentation about it. So how is it done?

If you don't know but you do know some (preferably quite small) app which uses led, please tell which app so I can check the source code.

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

The various patterns can be found in /etc/mce/mce.ini
You can also add your own there (caution if you edit this file!!!)

Maybe it would be better to use the low-level /sys interface? There's a little documentation in the wiki: http://wiki.maemo.org/LED_patterns#Low_Level

That way you could just use custom patterns without messing with a configuration file.

Yeah that's what I guessed but didn't dare to test. Thanks.

I didn't quite understand how that works. Care to give a little example?

Uhm, I was just pointing in the direction. That doesn't mean I've used it or know how it works. :o

Ok :)

Is it possible to do the dbus-send thingie and put somehow a custom pattern instead of those in the configuration file?

Re: How to use led? (Fremantle/Qt 4.6)
 

dbus-send is preferred to the sysfs approach because you don't have to be root to have the LED activated, AFAIK.

To add new patterns, you have to edit /etc/mce/mce.ini.
