What's done when the PPC turns off ?

---

Hi,

If you click on the on/off button, does the ppc really turn off ?
In fact I'd like to know how works the alarms ? Because you turn off the PPC and something (a system process ..?) must check the hour to wake up the ppc, launch the alarm ...
So is it possible to let an application running when the ppc is off ?

I answer myself

The solution for me is to use CeRunAppAtTime which wakes up the PPC with an application at the time set. Don't know if the standard alarm use this function but for my purpose it is perfect.

Love this site

Hmm, except that if you keep the GPRS connection up when in suspend mode, the CeRunAppAtTime runs the app, but does not turn on the display!

I have also tried raising a notification, and the display commands that media player uses to toggle the screen, but these don't work either.

Does anyone know how to get the display to come back on programatically when the device is suspended but the GPRS session is still connected?

Many thanks

Matt

doesn't seem to work anymore with 2003 though. Except when the device is connected to AC power.

Personnally I used CappRunAtTime to make my own alarm app to wake me up with mp3. And it works well. If the PPC is on it just launches the app, if the PPC is off it starts the PPC (screen on ...) then launch my app ...

You mean that if you have your GPRS always on, you turn off the ppc et the CeappRunatTime does not come back on ?
Wow I'm waiting my SD card adaptater to install the new rom, mainly for the 'always GPRS on'.

A question for both of you: does the standard alarm work ? I mean does it turn your screen on..? Because I supposed that the standard alarms work with CEappRunatTime ?

Hi

Yes the alarms turn the screen back on when gprs is set to always on. And that was how I thought the system did it by triggering the calnot.exe and clocknot.exe apps using cerunappattime. Although I was triggering the app to run a second in advance, and since then we have changed that to 10 seconds that that seems to work ok, it now turns the screen back on even when the device is 'pretending' to be suspended when gprs is always on.

Just curious, why do you need an SD card adaptor for upgrading the rom? You can just use the usb cradle, of course you have to have a pc and all the software i suppose...

I did the same thing (sleep(2000)) in my application to be sure that all the system processes are well woke up before I start the mp3 functions. I'll keep in mind that woke up the ppc, when GPRS is always on, may take a little more time.

I just wait the SD card adaptator to save my actual rom, which is a French Rom, before doing the upgrade. Just in case because I don't think Bouygues (from which I bought my XDA) will provide updated rom in french.

It seems that the cerunappattime doesn't like waiting for the time if you set it less that about 10 secs in the future, seems to just run the app straight away, and that didn't trigger the ce to wake up...

wierd, put it to 10 secs and it woke up fine. Don't think it has anything to do with powering up the system as it is mostly powered up anyway when gprs is always on.

well I always test it by launching an application one minute in the future so I never saw that case :wink:
