Under Connection Manager -> Tools -> Connectivity Setting there are two settings: Connect automatically: WLAN connections Search interval: Never This will ensure that whenever you click on a URL, if a configured AP is available it will connect automatically. But when you disconnect the network connection, it will not automatically keep searching for the network (Search interval). Also, setting the WLAN timeout to 5 minutes will ensure that WLAN is shutdown when idle. As you have found out though, Google Talk presence will keep network alive all the time.

I was wrong in what I said previously, with auto-connect disabled, the quite nice feature of the browser connecting without opening the connection dialog doesn't work (which is a shame). The 'problem' with google talk may be supposed to be a feature! Having a list of apps that are allowed to auto-connect and/or a hard timeout on the auto-connection would avoid this problem for those who don't want a flat battery in the morning. Even better (and to still allow for VoIP should you want to use it), would be to allow the user to manually configure the timeouts for different apps (e.g. weather/rss could have 30s every 20min then disconnect, VoIP could be always on, email could have 1min every 5min, etc.). If using an allow-list, the timeouts would have to be hard (e.g. something not on the list may be using the connection, so you shouldn't stay connected just because of that), and you'd need semaphores/some other synchronisation mechanism to stop allowed apps from being cut off in the middle of their slot. It would also require some thought about whether to reset the wait interval for the less frequent slots if they can use the connection instigated by apps that need to be online more frequently. Hope that makes some sense! This is obviously extra infrastructure work, depends whether anyone thinks it might be (more) useful I suppose.

Unfortunately, with default setup, you get an empty battery N800 if you stay at home : I've been hit by this bug saturday night : I put my brand new N800 on locked mode, before going to sleeping and it connected to my AP in the night (because of the auto-connect feature + jabber/google talk) and when I woke up on sunday morning, there was no energy anymore in it :( I tried to set "auto disconnect after 5 or 10 minutes of inactivity" to try to workaround it but the presence applet prevent inactivity detection. So, if you want to go to sleep, don't forget to put your N800 in offline mode before locking it (or disable auto-connect). -- Frederic Crozat <[EMAIL PROTECTED]> ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers

Then applications can still > initiate connection when they feel like it. I see. So when the keypad's locked (i.e. it's in my pocket), can an app connect by itself without my doing anything? I suppose it can as when I open the browser it auto-connects to my wifi router. But in this case, how's it any different to the auto-connect thing we're talking about? It would still be useful to have different timeouts for apps like this, which just want to (auto-)connect, check for mail/weather/rss/etc., and apps that I'm actively using and want to stay connected (e.g. when I'm using ssh). I agree that this would not be necessary if I'm always connected (waiting for VoIP, etc.), but some people won't want this, but will want to save battery life.

RE: [maemo-developers] Auto-connect feature
Hi, The idea is that N800 is connected all the time to known WLAN access points so that your VoIP calls actually do come in. If we go with any of your proposals this will not work, right? You can turn it off from the connectivity settings in the "Connect automatically" dropdown. Then applications can still initiate connection when they feel like it.

[maemo-developers] Auto-connect feature
Hi all, I was mightily confused that I'd wake my N800 up from its keypad/screen locked state and find that it was connected. I understand that this is a feature, and in fact it is quite a useful feature, however there are some caveats: This feature is switched on by default - for those who don't know about it (or need it, etc.), it's confusing and drains the battery. It would appear that the device will auto-connect with an interval set in the connection settings dialog. I assume it disconnects using the settings in the same dialog, which by default set the wlan timeout to infinite - this would seem to indicate that it will just stay connected all the time (again not ideal for the battery of those who don't need the feature). This seems to be the case as it's always connected when I switch on... I may be wrong about the timeout settings, please let me know if this is the case. IMO, ideally it should do the following: * Only allow certain applications to initiate an auto-connect, and if one of these is not running don't bother auto-connecting at all. * Perform the auto-connect as per the current frequency settings. * Have a different timeout to the normal (user-initiated) connection settings - this might be a hard limit (so after 1min it will disconnect even if there is traffic), or an idle limit (connect, then disconnect when idle for more than 30s, etc.) Just a few thoughts, Cheers, Simon ___ maemo-developers mailing list maemo-developers@maemo.org https://maemo.org/mailman/listinfo/maemo-developers
