I don't have an n810 yet, but I am looking to get one.
I was curious about what automation options there are. For example, I would like the device to wake up periodically (pref without the screen coming on), check to see if there is a wlan it knows available, otherwise start a bt DUN session, then check and download email. Then "bing" or do nothing depending on the emails available.
Can the OS do this type of automation out of the box?
Yes, it does automatically check mail. Not sure about whether it will dial a DUN session, but I think you can enable that. (Actually I'm almost positive you can, at least in 2007, and I haven't heard gripes about that going away in the 2008 OS on the N810's.)
It will most definitely do that. The only minor glitch is that it only changes Internet connection after the current connection is disconnected. Seems like a fine plan for Wifi (after all, why connect to a different WLAN if your current one still works). But it also means that once it's on DUN, it will never go back to Wifi, even if you are back in range (unless, of course, your cell phone goes out of range or kills the DUN connection). That's why I have the automatic dial-up disabled, since I rather have it not be on the net for the the 45 minutes a day that I am not in Wifi range than have to remember to put it back to Wifi everytime I come back from outside.
yep, there is a connection priority setting missing...
it could be made as visual as a number next to stored connections, and dragging them up or down the list depending on how they should prioritized.
so you would have something like this:
1. home wlan
2. office wlan
3. dun or pan
then if you want to use the phone before using office wlan for some reason, one would simply drag it up so that the list would become:
1. home wlan
2. dun or pan
3. office wlan
and then if non of those produce a solution, either present the connection list (if its a user initiated connection, say by starting browser or mail) or simply time out (if its a rss or mail autocheck).
if one wants a more fine grained control one could possibly have a list of apps (like how simple-launcher does it for selecting entries) for each connection to mark who could initiate what kind of connection automatically.
would be great to have an option which can set the device to online mode every 45 minutes for 5 minutes or something.
So that the battery is not discharged so fast, but I can still get the newest emails and rss-feeds automatically every 45 minutes.
Is it possible to write a program which can switch the device between online and offline mode??
If not can we write it somewhere on a wishlist to get it in the next OS update?
Yes, we all meant with the device "on" and connected. The N810 and N800 have a battery capacity of about 10 _DAYS_ while _ON_ and connected to Wifi. The ARM chip has some pretty amazing power scaling capabilities. At least with OS 2008, there is no "standby" - it's either on or off. But turning it on from off means booting up (takes about 30 seconds or so) and is not recommended for battery saving purposes. Some people claim that the boot up (where I/O and CPU usage is high) consumes as much power as a day or so of idle...
There is an "offline" mode, but that's mostly for airplanes (and as such, does not allow for an automatic switch to online mode). But really, there is no need for a "standby" or "offline mode" for battery savings purposes. (I guess if you are a purist you could argue that there is a need for it, but the inconvenience of having to worry about an additional power state etc... is not worth the minute benefits, IMHO).
I see a big difference between online and offline mode with my N800 and OS2008. in online mode i have a battery time of 1-2 days.
But it depends on the distance to the WLAN-Router.
When you speak about 10 days what wlan strength do you have?
Or is there a difference between N800 and N810?
Or is the reason for this difference maybe that I have rtcomm always running with different profiles enabled?
