Hey guys,

I've had my n900 for a few days but I have an annoying problem with LED notifcation failures for SMS and charging.

It's a vanilla UK handset running the latest UK firmware (I updated OTA with app manager).

It's not been modified, and I've only enabled Maemo Extras repo.

Apps installed are a few games from Ovi store, Foreca weather widget, personal dataplan widget, Facebook & sharing widget (but it was not displayed on desktop) and Xchat.

Notification settings have LED set for calls/sms/charging.

Yesterday I noticed the LED failed to flash when I had an incoming SMS. Also when the unit is on charge, it didn't glow orange.

I rebooted, still same problem. I then enabled all notifications and the LED flashed for missed call, and Device On worked but still no SMS or charge light.

I took out the battery and I still had the same problem. I then did some searching on here and looked at the mce.ini file.

This was timestapped Dec so it's not been touched. I had a look in it anyway and it has the relevant LED pattern bits so SMS should work.

I then reflashed the firmware via NSU and charge/SMS LED light worked ok again. I added all the same apps back and today, it's failed again for sms/charge notifications.

Did the same reboot / take battery out step but still nothing.

There's a thread here with a script to test LEDs via dbus. I ran that to pulse the LED for SMS notifcations for 10secs, still nothing.

Tried restarting mce, nothing. Device On, missed call notifications worked OK.

I then uninstalled all the apps, rebooted, took battery out and it's all been fine for the past few hours. I have installed the games back from the Ovi store but nothing from Maemo Extras.

I'm running the dbus script to pulse the LED for SMS every half hour or so and it's been working OK. The orange charge light is also working fine.

I'm not sure what's going on, if I had a LED problem I'd expect it not to flash at all. I don't know for sure if the apps are causing a weird problem, does not sound likely they would only affect charge/sms notifications.

Anyone come across this?

Cheers.

hmmmmm wouldnt have expected any of those to cause an issue :|

Does sound like a really odd problem :| - best to keep an eye on what you do/change for a few days :P

Yeah it's really weird and a total pain in the butt. I'm goin to keep it in this state for another day or so and see how it behaves.

The test script I use is:

#!/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

Is there a command or a flag for dbus-send to make it much more verbose? When it works I can obviously see the LED pulse.

When I have this problem, the script runs as normal but I'd like to see some debug info. Might help to shed some light on the failure.

Cheers.

don't think you can debug the dbus calls.... tis a pity though

Couldn't see anything related to verbose output except for a "--print-reply"

Sticking that in the script and running it while my SMS notifications work results in:

method return sender=:1.7 -> dest=1.310 reply_serial=2

Will see what that does when notification is broken.

Cheers for your help.

Just to follow up, looks like the culprit was Personal Dataplan Monitor.

I've put back all the original apps (and new ones) except the Dataplan monitor and I've not had any LED problems since my original posts.

K.

Thanks for the update

I have the same problem but i don't have Dataplan installed on mine? I must be honest it doesn't bother me that much as it starts working again for no reason? I can see why it annoys ppl. When i put mine on charge the orange doesnt work, instead i get a really dim white flash?? Power on flash doesnt work but all other notification does. Really wierd? I just leave it n it starts to work again. Heres my installed apps...

3g/2g/duel mode selection app
anglemeter
angry birds
bounce
camkeyd
datetoday home widget
drnoksnes
extra decoders support
fapn
fmms
forca installer
forca widget
ioquake

petrovich
picodrive
qtirecco (which i'm having big problems with btw)
rootsh
sharing plugin for fmms
speedometer

vncviewer
toutube video uploader

If i can remember i had this led problem quite early on before i installed any apps so i'm sure its nothing to do with what i've done?
Anyhoo, it works fine 90% of the time and its such a small problem that i can live with it.
