Hi to all and thanks for the great tips on this forum. We've been doing a lot of pocketpc development but are new to XDAs.
As most of you would know the new ROM allows the XDA to keep it's connection alive - well, as alive as GPRS will allow it to whilst still letting the screen etc go to sleep.
Does anyone know exactly what it is doing when it goes to sleep as it seems to be doing more than just turning the screen off as we can't seem to turn it back on with the normal calls?
Cheers

Is there an option/reg edit to enable WiFi in such a way that it is always on? I know that this drains the battery, but I was just wondering if I could let my PDA be online through WiFi while it is in sleep mode.
Cheers, E
I'm not sure but seem for me last week that the wifi was still on with my pda "powered" off BUT was connect to power supply ...
Any solutions
I wanted my wifi to stay on as well during sleep mode. Is this possible? I wanted it on for my VoIP.
my wifi turns off when switching to standby an when i reactivate the phone from standby it turns on again.
what i am doing is to turn of automatic standby switching to let wifi on. only thing is, that the battery runs dry very fast
any other ideas?

PDA can not keep the Wi-Fi card on while sleeping. I have done lot of re-research in that area trying to switch on the wifi while in Sleep mode (building my first app rk-OSR). Technically while at ‘Sleep’ device is in ‘coma’ like state consuming very less power. Most of the applications which work in Sleep are not actually in sleep mode but in ‘Unattended’ mode. But it is not easy to get to unattended mode just by reg entries.
Since it would drain the battery so fast even if you manage the impossible, I would assume you would have to connect power cable and find a way to turn off the screen while connected to your wifi access point, may be the only option for you
Thanks dude. Guess I'll just have to use a VOIP phone at home, seams a bit handier then my PDA
Do you know if it's possible avoid turn-off wireless in stand-by???
I'd like to use VoIP with my Artemis (with hand-free and wireless connection), but it's impossible becouse after 1 minute (my pda is set to turn-off after 1 minute) the phone goes in stand-by mode and plugs off the wireless antenna.
Can I set "Always on" to wireless connection???
as yet i failed to accomplish this. all i can do so far is turn off the monitor to save a bit power. not the same as standby mode at all though.
I've got this tweak from somewhere, I'm not sure (maybe wiki page):
"AUTO DISCONNECT WHEN GPRS IDLE
you can edit the registry key ...
HKey_Local_Machine/Comm/ConnMgr/Planner/Settings/CacheTime
Change from 600 to 60
it will disconnect after connection is idle for 60 seconds ...
There's also another key needed to be set. Otherwise, my PDA still has always on 3G data connection.
HKey_Local_Machine/Comm/ConnMgr/Planner/Settings/SuspendResume
Change from ~GPRS! - Always on
to GPRS_bye_if_device_off - switch off after timeout"
It may help if you make the changes THE OTHER WAY ROUND. For you the desired value in 'HKey_Local_Machine/Comm/ConnMgr/Planner/Settings/SuspendResume' is '~GPRS!' And the cache time value should be set to '0' (as infinite), if it doesn't work, set to a high value (i.e. 3600 - it means 1 hour).
I'm not sure it helps but it's worth to give it a try...
i guess he was talking about WLAN connection, not gprs or 3G. however, i might be wrong.

You are right, sorry. I've just misunderstood the problem, paying not enough attention to the first post...
So the only way is disable auto sandby and swith-off screen?
I thought a way to solve this situation could be keeping active OS during VoIP connection, just to avoid standby...
Its not enabled for a very good reason, it consumes so much power your device would last just a few hours before running out of power.

that is true. however, they could still give us the option
i think the real "problem" is that WLAN needs the OS running to work. the GSM unit is working differently.
Using S2U is a solution for me
Using S2U2 is the only solution for me.

It seems to be what I want, an application that avoid standby mode but preserve battery (setting lcd off, various device option off...)
I'll try it!
Thanks
Skype
I am not sure if this is still relevant, but in skype i think to have seen an option that says: "disable stand by mode when connected to Wlan" or something like that...
however of course the "batteryproblem" will still be there...
Please post your experiences with S2U2 once made, thanks!
Don't mean to "thread jack" but how can I tell the difference between the screen just being off and the phone being in standby mode?
I'm asking because I'm having a problem with my phone when I turn on Flight mode. Usually I turn on flight mode at night or in a meeting but I'm finding that the battery is still draining (rather quickly too) when I'm in flight mode and the device is off all night. If I'm at 40% batt level at 11:00pm and put the phone in Flight mode, by the morning about 6:30am, the battery is down to like 5%! And there are no programs running at all, screen is off, device is untouched all night. So when I saw this thread, I started to wonder if the phone was in really in standby or if the screen was just off.
Is S2U2 the option to keep the WLAN enabled when in standby mode?
I know i can disable going in to standby but would be nice if it can be done without this.
The power drain is most peoples concern but if i'm at work i have it plugged into the power anyway but would like to use one of the WLAN's here that isn't being monitored
Is it possible to use gps in the standby mode for gps tracking or something?
Every time is switch my device to standby the gps doesn't work.
I know its possible to use wifi during standby with an registry-tweak.
Anybody knows such a tweak for gps?
Sorry for my bad english

I came across this little program when i first got my touch pro 2, it should do what you want and make the GPS stay on even in standby

Hi, I'm on @Sultanxda CM13 ROM. After switching Wifi keep alive to never, wifi disconnect in standby but never reconnect till I switch wifi OFF / ON again. Can someone try and verify if this is a bug? Thanks
Anyone? Did no one uses wifi keep alive = never?
Nah, i keep it alive as always,
Notification wont going in if you let it sleep, so unless you are on low batt, i see no reason doing this,
Notification comes in via LTE data connection on my side and as you mentioned battery is one of the reasons to do so.
Anyway there is an issue with this function, also on other devices (i.e. nexus5X). http://forum.xda-developers.com/nexus-5x/help/6-0-1-wifi-sleep-issue-t3271788
For this device they fixed it with the july update from google. Perhaps there is also a patch missing on our loved OP3.
Just for the record.
I'm now using the "Wifi Automatic" App https://play.google.com/store/apps/details?id=de.j4velin.wifiAutoOff
to toggle Wifi. This is my mitigation to the issue.
