Auto Disconnect GPRS while device is asleep

Hi, I know this topic has been covered many times, but I here's my issue.
I have phoneAlarm running on my Trinity and set phoneAlarm to cut my data connection after 1min of data inactivity and it all works fine. I can browse the web, check emails using the WM5 inbuilt email application. After 1 min of data inactivity, my connection is cut, brilliant, works like a treat.
However, once the device is asleep, and my email application polls, the data connection remains connected (if there are no emails, it won't wake up) and I have to switch on again and either let it disconnect when awake, or manually disconnect it.
The funny thing is, its just the email application thats causing this. If I was browsing using PIE and just press the power button whilst it was still connected, it times out and it gets disconnected, and the next time I wake up the device I can see there is no data connection.
it seems like the WM5 email application whilst asleep is either holding on to the connection or some data is being transferred, as I said it doesn't happen if the device is awake.
This really is bugging me, as the whole point of setting up "Auto disconnect" is so I can leave it and trust it to only connect when need be. Currently, if I don't use the phone and don't receive any emails, my GPRS connection is on all the time whilst the phone is asleep.
I have tried other programs, but generally, all of these applications perform the same registry tweak.
Sorry for long post.

I did a program (ConnectionManager) that wakes up the pda to Idle state (screen off, no sound and cpu to minimum level) each 3 minutes and check the states of connections. If there isnt traffic in 2 minutes the connection is closed.

Hi,
Interesting. Do you have a link to that program? Tried to find it in the forum by searching for "ConnectionManager" and found nothing.
So when the device is in idle state, min CPU, screen off etc, there's no problem in accepting calls etc?
I was reading a thread regarding the other program you wrote that switches bands, was interested in that too.
Thanks for your help.

Don't worry, I've found it, and it WORKS. You're a star!!!
exactly what I was looking for. It did come across it before, but for some reason I thought you didn't check for data flows and close the connection full stop. Obviously i mis read
I've downloaded WM5 SDK, but didn't really know where to start, I am a developer, but don't know anything about the WM5 APIs. Cheeky question, but is it possible to let me have the source code?
I would love to enhance something like this, would love it to be a today plug in and let you enable it without opening a new form. Settings about how long before checking. Not sure how easy it would be.
Just a comment really, not sure if its just my device (Trinity) but the Close Program button seems to be out of shape, i.e. larger than the other 3 and goes right to the edge of the screen.
Oh, one more question, do you think having the device on idle will have much impact on battery life. Once the device is in idle, does it suspend again, or does it keep it in idle until you switch it on again?
Thanks again!

Hi, another thing. Having tried this program out for a little while now, it seems to not let the device time out into suspend state. For me, it seems to just lower the brightness of the screen. The program still works, but it won't let the device suspend automatically, i thought it would switch it to idle, and turn of the screen.
Once the machine is suspended manually by pressing the power button, then its fine. Do you have this issue?
Still works like a treat though, and better than anything I had before!
Thanks again!
Sorry, my mistake. It all works fine!

Hi. I was going to do other release (the user can modify connections check, etc) but i will post the source code, sure (but the source code is in my laptop). tomorrow i will post it.....
Greetings

Idle is a state with minimum impact...but is bigger than suspended. When the device wakes up to idle state it is suspended again after a few seconds if the cpu isnt used too much. When the device is woke up by a app notification (Its our case) the system suspends very quickly. In my tests (using log method) the program does its stuff (1 seconds) and 10 seconds later the system is suspended again...
I ve used Visual Studio 2005 and the program was wrote using C (not MFC)...

Hi Daniel
Where can I download this app ?
Thanks and regards

I am curious if you gprs comes on for your push mail, can you still make outgoing call and also send text messages?. I have this issue for my atom exec and it's annoying me. Thanks

Data Auto Disconnect

I'm sure this is a noob question, but I can't find the answer on the forum.
I've seen a couple people reference automatically ending the data connections when they're idle. Can someone explain how this is done?

Is the desire to disconnect the data to save on battery life? Just curious. Thanks.

That's the main reason I want to do it...not sure about others...

I figured out two ways to do this for anyone else that's interested.
1) Using Advanced Config Tool (V3.3): Menu > More Settings > Connections. Check "Disconnect After" and set the timeout you want. This seems to work well for activesync connections (my mail is set to recieve every 5 min), but doesn't always work for on demand connections (Internet).
2) Comm Manager Pro. No instructions for this since I'm not using it (yet). But everything I've read looks like it does it.
Like I mentioned, I've got my email configured to sync every 5 minutes and I have a connection timeout of 30 seconds set in Advanced Config. This setup has drastically improved my battery life. Before this change, I got maybe 12 hours on a good day. With this timeout set, I could probably get 2 solid days. The only thing I haven't figured out is if the timeout is and idle timeout or an overall timeout. What I mean, is will the connection end after 30 seconds even if it's in use?

I'm interested in this as well, it would be even better if outlook or msn live would make a connection and disconnect after synchronizing.

I've been looking for the same solution. So far using advanced config settings will force disconnect no matter if it was idle or not. I'm looking for a solution to disconnect only when idle.
As of proof, set auto disconnect to 1 minute and using latest skype v3.0 start transferring a large file. After 1 minute data connection will be forcibly disconnected.
Any solutions for this?
Thank you.

Can someone help me find the timing setting in Advanced Config? I've looked through everything - using Energy 3.0 Rom (WM6.5) and don't see anything related to data disconnect other than under "Data Connections:" "GPRS disconnect:" and my settings are "Enable button and timer"
I don't see where the timer comes into play; don't really care if the connection gets cut off - I'd rather see a battery life improvement.....
I'm an absolute idiot. I just skimmed through the thread and didn't read the post above... *smacks forehead*

Its been posted in this very topic, and its only 5 replies long

In advanced config the settings you are looking are not located in the list on first screen, the are in separate menu as described above.
And now I'll quote myself so my question will not get burred:

Thanks for the link, unfortunately it still disconnects even if data connection is in use.

WMLongLife can do this for you.
About the registry tweak that does this, I must warn you: it disables the ability to do voice and data simultaneously.

Yes it does require a certain way of using your phone (current test version has specific settings - you can change this in next version). Just saying.

Yes it can, but it depends on several factors. Under ideal (and never actually occuring) conditions it can be done with 2G GSM (GPRS/EDGE). Normally, however, either GPRS/EDGE connection suspends ('pauses') during voice call, or with 2G CDMA voice call may not work at all while data connection active (depends on exact 2G CDMA network type).
With 3G GSM (UMTS/HSPA) it is quite possible (and normal) to do data and voice simultaneously, however for some reason the auto data disconnect registry tweak breaks it. I'm not quite sure why, but it does.
3G CDMA (EV-DO) behaves the same as 2G GSM with regards to simultaneous voice and data (data drops), however, EV-DO Rev. A behaves the same as 3G GSM (possible but broken by registry tweak)
Aside from this, it is also needed that your provider/network has the correct hardware to handle this. I'm not sure how common it is for this properly operating on EV-DO Rev. A, but for UMTS/HSPA early tower equipment was bugged and did not allow this. In Europe, most UMTS/HSPA towers have since been upgraded to allow simultaneous voice and data (and HTC handsets support this perfectly), but how this is in the USA I cannot say.
Hope that explains it (it is a bit messy explenation I know)

if this dowsn't work then i have no ideea what will )

!!!!!
I had it set to disconnect (via Diamond Tweak software) after 1 minute of activity. I did this to preserve battery life, BUT BUT BUT
With 3g on, and even with 3g disabled all day and edge on, the battery still died in 8, 12 hours (3g, edge) with the connection disabling. i use the phone for a good number of calls, text, and some data every day.
AFTER i reenabled it to NOT disconnect after every 1 minute, i pulled over 24 hours on a SINGLE charge.
am i the only one that's experienced this??

TURBO GPS fix on Touch Pro

TURBO GPS fix on Touch Pro
(contrary to many of the GPS fixes offered on the net)
I read a lot of fixes on how to make the Touch Pro lock on to GPS faster. Being an ex-owner of toshiba G810, which is the fastest GPS PPC i tried ever before, and noting that it uses the same GPS chip as in the Touch Pro. I tried to emulate the settings in the registry, and i got an excellent result, so would like to share that with you.
1) Many of the fixes on the net talk about turning off the A-GPS , i think this is "wrong" thing, cos when A-GPS is turned off, it would not be able to use the valuable satellite data downloaded from QuickGPS. Therefore, i use Advanced Configuration Tool to turn it back on (ENABLED).
2) I changed the HKLM\SYSTEM\CurrentControlSet\GPS Intermediate Driver\Drivers\GpsOneDevice\PollInterval -> 500 (default is 1000),
which is the same figure as in my Toshiba G810 before.
3) keep the log files untouched, i.e., DO NOT delete:
\windows\GPSLogFile.txt and \windows\GPSLogFileBack.txt
(if you have deleted those 2 files before, just create 2 blank .txt files with those filenames and put them back in \windows. When new GPS data comes in, it will append to the blank files, older data get deleted once reached the 32K limit set below.)
4) keep maximum size of logfile to the default which is 32K
Voila, now my Touch Pro always get 4 to 5 BLUE bars on my mapking (which mean dead lock on!!!) And it it wont fluctutate lock on and off intermittently.
Really urge you to try it, and let me know if you get the same results~~
Cheers everyone!
(For those who dont like tweaking with registries manually, krish_nank has been kind enough to make it into a .cab which i attach here.)

nice experience, i'll try it

Please write back to see if it works welll for you. And make sure you use QuickGPS once afterwards to get the satellite data before you start GPS.

I don't have any kind of data connection with my network so AGPS is useless for me, however I did try changing the polling from 1000 to 500 and I managed to get a lock with GPS test within a few minutes inside my own house! Can't remember getting the same results before.

I can only agree that
1 - touching log files is BAD.
2 - reducing poll interval will improve the GPS lag slightly
3 - keeping A-GPS up - in my country there is no A-GPS data available since thats the data provided by the provider over the local network cells. I dont think it has anything to do with the data from Quick GPS. But i might be wrong. Anyway, Quick GPS is your friend.
4 - if you have fix problems its usually either not having Quick gps data or trying to get a fix in a bad area or under a shielded windscreen.

overtweaked?
I changed the pollig interval to 100... is it milliseconds?
I haven't tried it yet but would it be a battery drainer like this (100)?
Actually I was hoping to reduce the delay of map in garmin or oziexplorer (which are my favourites) in higher driving speeds. I tried garmin while driving over 200 km/h and there was a damn nasty delay on the map. Of course it was a stupid risk to watch the screen during these speeds

I tried 1000 (default), 250, 125, and 64 Pollinginterval and none of them were as fast as 500.

well it would be slower because you are polling to often then. best thing to do for your gps speed is update your radio to 1.12.25.19. it doesnt take long to do. then make sure agps is enabled and update your quickgps data. increasing polling from 1000 to 500 might help but i havent tried yet.

ok i changed the polling and with my radio and quickgps i got a lock in under 2 seconds. i havent seen any gps device that could do that.

Thanks for your testing.
It seems that Toshiba G810 polling setting (i.e. 500) really works for a lot of us.
I was originally so amazed at how G810 could do it, and was so sad to see how bad my Touch Pro (which costs twice compared to the G810) is performing.
I'm glad at least now i can make my Touch Pro just as fast.

I have not had issues with mine with warm or hot starts (most was 30 seconds). What I need to know is from a cold start, how long it takes to perform a fix (you can verify using the HTC GPS tool).
To do a cold start, reset the unit with the button near the USB connector or if you have StartXP, use that.

I think wildboy did do a soft reset, it's kind of standard on XDA.

Without AGPS? Or is quickGPS similar... can't remember I forget now

agps needs to be enabled for quickgps. agps hindered gps on older radios. the newest radio works really well with agps and quickgps.

I kinda figured as much, but I just want to be sure. Mainly because with my current settings I am getting the same performance, except when I have a cold start. I am trying to figure out a way to get better cold start performance.

Thanks a million .. your tweak is working great. now i can get my GPS locked in 7 seconds
Once again thank you.

omg, this worked for me indoors

I never played with the Log file....
I do not have a GPS*.txt file in my windows folder, using EnergyROM 2.0 4.12.09...
Will those/can those files be generated by a program other then quick gps or visualgpsce?

Just install AdvancedConfig, this will allow you to edit the buffer size of the log files and verify their are log files in that ROM. Then you just need a Registry Editor to adjust the polling time.

Pretty strange but I haven't modified mine at all and it locks on in about 10-15 seconds which I think is pretty good, or isn't it?

Sorry, slight miscommunication..
I'm using EnergyROM 2, and i'm familiar with Adv. Config & Registry editing..
Default setting was no logging, and I can't point adv. config to the log file that doesn't exist.
If i just make ablank log/text file, and point it, will that work? Or do the log files need to have certain information in them in order to not screw up?

[REQ] A Better Solution for Data Auto-Disconnect... with Peak Time/Push Mail

Hi folks
I've searched around the forums and have seen a couple of solutions out there for automatically terminating data connections (Bandswitch, WMLongLife, the registry tweak) but each seems to lack some of what I need and do a lot that I don't need.
Here's the lowdown:
- I've already tweaked the Comm Manager to add the 3G on/off switch so I don't need something that messes with that
- I use push email for business so I need the data connection to stay on during the "peak times" that I've set in Activesync (for me, that's 8am-11pm)
- Outside of peak times, I've got the phone checking email every hour. Right now, it seems to be leaving the connection on afterward.
- I want to keep the automatic updates for HTC Sense's weather and stock tabs. Not every 5 minutes, of course, but at least a couple of times a day. Also tends to leave the connection going when used outside peak hours.
As I understand it, the registry tweak won't work for the Sense tabs. Bandswitch and WMLongLife mess with the 3G radio and, as far as I can tell, don't let you set a timeframe (re: the latter - I suppose when you've got push mail going it pings the Exchange server regularly so in theory it shouldn't consider the connection idle, but why mess with it?)
So, in short, anyone got a solution that could switch off an idle data connection outside of the peak times set in Activesync?

If you just want to kill connections during certain times (ie, night time) try G-Profile. I have it set to kill data connections during the night, works fine for me although I am using a new beta version which is available from their site.

Looks interesting but reading through the manual it looks as if you can only set a profile to disable the data connection during certain hours. I'd like to leave the data available, just switch on auto-disconnect.
Plus, again, there's a lot of extra stuff in there that's really not necessary. I'm looking for something more lightweight...

I haven't tried it, but you might want to take a look at CommMgrPro.
It's also from the creator of Bandswitch.

PhoneAlarm can do this.

I had PhoneAlarm installed on my previous phone. True, it can do this.
But again, it's like using a tank to kill a fly. Sam with CommMgrPro.
Is there no lightweight solution?

+1 for this. It has to be possible, everyone just seems to lump the functionality in with a load of other stuff I'm not interested in.

Up, I'm looking for this also

+1
This kind of app is missing...

SO.... last night I left my charging cable at the office and I only had around 20% of the battery left at 11:00pm. For some reason, the thing kept opening the data channel even though it was outside of "peak" hours for push! I had to reset and turn manually turn off all data... couldn't have the phone die overnight as it's my alarm clock!
Any ideas here?

[REQ] Looking for a mobile network timer app

Hello, everyone!
I have recently switched to another mobile operator which has cheaper data plans.
I enabled an unlimited data plan that charges me 0,12 euros every 15 minutes of connection to the APN (plus 4,00 euros every six months) over HSDPA bands.
I'm looking for an app that works as a time limiter of data usage, so that I can set it to stop every connection (disabling the APN or calling another app to do that) when reaching a predefined amount of time for internet usage. I would set the limit to 1 hr/day = 50 cents.
I would be very happy if this app could also send notifications every tot minutes of data usage. I would set notifications to pop every 15 minutes = 12 cents. I realize that this is not a critical feature...
3G Watchdog would not help in my case, since I have an unlimited data plan and it's got no time counters but just data ones.
So, can you help me? Is there an app out there that performs the way I described?
Thank you very much in advance!

So there is no limit on data usage and only a limit on time?

zeppelinrox said:

Actually not. That's why I want to monitor my time spent over HSDPA, because it has no limits and I can forget about how much time I'm using a data connection and how much I'm spending!

Your request looks possible, the problem is see is not with the app itself, but that services like email/gmail/sync will probably regularly use the internet connection and use up the time.
There are options to tell apps not to use internet while in the background, if the developer programmed right they shouldnt use it up .

Yep, that's no problem. Since I activate APN manually, I also activate autosync manually with Extended Controls. Apps don't sync in the background unless I tell em to do that.
Maybe this app should be left running in the background and trigger the timer when APN is activated.

Actually not... this is the page, but I'll translate the important parts for you:
time-based navigation
50 cents per hour
surf up to 14,4 Mbps
just 4 euros every 6 months
Pricing applies to sessions. Every session lasts 15 minutes and costs 12,5 cents, charged in advance. In case of disconnection, the current session gets aborted and when reconnecting, a new session will start.

It's pretty simple and this carrier is crystal clear, so there are no hidden costs! Just in case they'll change the cost related to a session in the future, I think it would be nice for this app to let me set the price per session and its lenght.

Have you tried SPB Wireless Monitor?

It cannot disable your data but it is able to gives off alarm depending on how you set it.

Yes, it's a good app, though I have to tweak settings a lot since it was made basically for monthly plans. It doesn't let me set each session lenght and doesn't have an option for charging in advance, so I'm finding a way to "trick" it, because at the moment it's the only app!
