Re: n810 GPS API?
Mihamina It's possible it uses gpsd but I haven't really seen any details yet. gpsd clients use a simple client library to talk to the daemon. Power management of the gps is also an unknown. gpsd can close its connection to the gps when no clients are connected, but I don't know if that's enough to work with for automatically powering down the idle gps.

n810 GPS API?
Hi, My boss heard about the n810 and asked me to port a Pocket PC Java application to the n810. It was a non free application that used the GPS of the pocket PC. Would you have any documentation about the interaction and frame capture of the GPS module on the n810?

Hacker Edition: a short review
Hi, when the latest Hacker Edition (4.2007.36-2) came out [1] I just couldn't resist and flashed it on my 770. Now after some weeks I can honestly say that I do not regret it. (Neither did I regret to flash HE 2.2006.47-17 ;-) [2]) Flashing and restoring my backups worked flawlessly. As soon as I was logged on my network I started installing all needed apps such as xterm, mplayer for 770 (!) [3], nano and ssh as well as many other great apps. For some of them you will need the “red pill mode” [4]. Ext2 I prefer to use the ext2 filesystem on my mmc. All I had to do was to add /sbin/insmod /mnt/initfs/lib/modules/current/mbcache.ko /sbin/insmod /mnt/initfs/lib/modules/current/ext2.ko to /etc/init.d/rcS. That will load the necessary kernel module for ext2 support during the start up process. That's it. Automatic mounting of ext2 formated mmcs works out of the box. Seatbelt The 770 is a great device but its resources are highly limited. 64mb ram is not much – therefore a swap file is a necessity. There is a garage project called “seatbelt” [5] which will change the 'swappiness' kernel parameters. Higher values will instruct the kernel to use the swap file more often instead cleaning the cache first. You can check the actual value with: cat /proc/sys/vm/swappiness The default is 1. Seatbelt will set this value to 100. It has been discussed that the lac of free memory causes the web browser and sometimes the whole tablet to crash. I can confirm that I have not managed to crash neither the web browser nor the 770 yet. Even under hight load, with many web pages open, streaming audio in the background and other resource intensive tasks running the system remained stable (although it became very slow). The whole system seems more reliable and stable with the latest Hacker Edition and seatbelt running. Also audio playback is more fluid. Wlan connections One disadvantage I noticed was that the 770 will drop connections more often when the power saving timeout value is set to low. I had to increase the wlan power saving timeout (psm) to a value above 300 by either using the gconf-editor or by applying: gconftool-2 --set --type int '/system/osso/connectivity/IAP/wlan_sleep_timeout' '300' Now video centre, radio streams or videos over a upnp share will work (at least for me and my ap). Conclusion The Hacker Edition for Nokias 770 has become way more than just a way to develop for bora (in case you don't have a n800). The 770 is a great device and the Hacker Edition takes advantage of its capabilities! Sure, not everything will work such as skype and microb browser, but it fits my needs. I can recommend the Hacker Edition to everyone who is willing to learn more about Linux on embedded devices and who wants to release the whole potential of the 770.

I maintain part of the one we have at our company. (what do you mean it lost a file?) I know what had to be done at Mandrake both for new releases and for back ports. Here though there is the "Apple Advantage" in that the environments are tightly controlled by Nokia. All 770's match hardware. No two x86 systems are alike. On the binary vs source uploads I guess it's obvious where I stand. I'm a lot more paranoid than I should be most likely.

Your poor IT can go nuts trying to find a connection. *grin* When I first got my 800 I noticed that when I left work, and drove home down the freeway by the time I got home (1 hour later) my battery had dropped 50% so I disable the auto connect and no problem. The 800 isn't too good at searches done at 80mph Other thing I learned. Don't put it on phone autoconnect. Kills your phone battery.

I would try testing the battery without WLAN and anything else running, just in standby mode. It should last about 10 days like that. If not, either there is something waking up the CPU all the or the battery is broken. I know that it's difficult to not use N800 for ten whole days.

Yeah, if applications send lots of data, naturally that will increase power consumption dramatically. For these cases it would helpful if you could install tcpdump to the device and take a dump of traffic. You could do it like this: tcpdump -i wlan -w dhcp-1.cap And then attach dhcp-1.cap to the bug report.

"ext Frederic Crozat" <[EMAIL PROTECTED]> writes: > Just curious : is the n800 really supposed to last "days" when connected > via Wifi (with full WLAN Power Save mode enabled), without any > disconnect timeout and anything doing network access on the wifi link ? Short answer: Yes, even with the default WLAN PSM settings. Long answer: It depends on your network. Here are few items which mostly affect WLAN power consumption: o N800 transmitting something periodically (once in a minute is not bad, once in a second is really bad, Google talk has 30s interval which is ok). o Buggy AP which does not support WLAN PSM properly. o distance to AP (WLAN background scan will kick in if the signal level is -75 dBm or less) o Lots of broadcast and multicast packets on the network (like Windows samba broadcasts). Also WLAN settings (beacon and DTIM interval) affect power consumption, but not before the issues I have listed above are ruled out. And this was only about issues related to WLAN, if there are other processes waking up the CPU that will naturally affect the standby time. For the background scan there are going to be some optimisations in OS2008, for example the limit will be lowered to -85 dBm. > When I check battery applet (which is really great btw), I'm never sure > if the "in use" time is applicable when being idle AND wifi connected.

If not, I would guess that after a bit of investigation you might find what's causing the high power consumption. tcpdump is your friend.
