How to maximize GPS battery life ?
Hi folks, if I want to use my FR as a GPS track logger (for an OSM mapping party for example), what is the best way to save battery life ? It seems that GPS chip is able to keep the fix while FR is suspended (/sys/devices/platform/gta02-pm-gps.0/keep_on_in_suspend), but I need the CPU to log data, don't I ? Currently, I think I would do something like this : - shut down GSM (FR is also my phone) - launch fsoraw -r GPS tangogps and start logging - let the FR disable display after 30s (problem : any touch on screen will keep it up) Any idea ?

You can unlock by pressing AUX, and no touch screen - no waking up!

I checked also empirically with my HI-FI amplifier the rf noise: when I check my credit, start a call or send an sms I'm able to listen the typical tarata-tarata-tarata... but when I launch the gprs connection all is quiet! deep silence! so, imho, something is not working in the latest qtmoko release.

The GSM chip has an ARM cpu. It is possible to run code on it and
modify it to buffer the data to its own memory so that you only need
to wake the main CPU once every 10 minutes or so.
- launch fsoraw -r GPS tangogps and start logging
tangogps consumes cpu time uselessly. I just
echo
'?WATCH={class:WATCH,enable:true,json:false,nmea:true,raw:0,scaled:false,timing:false}'
| nc localhost gpsd $HOME/gps/`date -Iseconds`.dump
currently with gpsd.

I have been using
http://iki.fi/lindi/openmoko/touchscreen-lock.c
for a year or so. It locks the touchscreen so that X does not see any
events unless you swipe the screen slowly from top to bottom with your
finger.

I carry a set of external usb batteries with me when mapping. See

you have qgpslog as an only logging app.

You can try to experiment with AT log or disable multiplexing, but i dont know anything better for now. Regards Radek hi radek, i tried rebooting with mux and deepsleep both disabled (neocontrol) and checked the at log (temporarily enabled)... all was ok and i can use arora with my gprs connection. i reverted back mux and deepsleep, rebooted with on/on and my gprs is still ok! :) i do not understand what was wrong before... but now all should be the same again, instead my gprs works a lot well :D btw, i can confirm sometimes the first attempt to start the gprs blink a while but fails... just try again and it's ok. kind regards, a. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Hi Radek, I think that it is caused by internal multiplexer - sometime it start to work incorrectly. I don`t think that its kernel related. My idea is to disable internal qtmoko multiplexer and use external daemon and configure qtopia to use multiply ports. I hope i will have some time to play with this in the feature, but still not sure when this could happens.

Re: Got also a WikiReader now
It's easy to load languages on the card. But unfortunately, they don't have a Polish Wiki yet. As long as you get the international Wikireader, it supports up to a 16gb microSD card. International comes with an 8gb. English takes up about 5gb.

qtmoko apt sources.list configuration
hi i think it's not a good thing to hardcode the german apt mirror for the standard configuration in the mass qtmoko distribution: - almost every user will not configure the sources.list - it's not always the best choice, eg if you are not in europe - we could weigh down the .de mirrors (ok, maybe one day everyone in the world will have a FR with qtmoko ;D ) what about apt-spy? http://www.debianadmin.com/check-debian-archive-mirrors-bandwidth-using-apt-spy.html imho we should automatically run it before apt-update in R(apt)or... what do you think about this? bye ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Have you continued restarting QtEI to see if your contacts reappear? Have you used another phone or a SIM card reader to verify your contacts are still on your SIM? Yes, i something like this in qtmoko. I have to wait ~30 seconds after entering pin and after that contacts appear in list. Very rarely they do not appear, and i have to restart qtmoko. Also, in some older release (in june i think) i noticed that if i wait too long and pin question visible for may be 15 minutes, contacts always not loaded.

usb-mass-storage, data corruption, QtMoko v26
2010-09...@18:13 Alfa21-mobile and now a question from me: when the usb mass storage mode is enabled, all the used partitions is in read only mode.. I see qtmoko exports also the rootfs and imho it's not good because if I forget to switch off the usb storage ... it's bad for the whole system. the question is: how I can configure qtmoko to use only a specific partition? eg the one mounted on /media/card only? about g_file_storage... we have this DOGMA: an usb host will not expect to see any changes in the storage other than the ones it makes. I found a critical (if the rootfs is on uSD) bug concerning the use of g_file_storage with the scripts in qtmokoV26!! - the # mount checking if, in /opt/qtmoko/bin/usb-mass-storage-on.sh is too weak because: 1) by default /etc/fstab in qtmoko contains rootfs for / and any root partition on the uSD is not found by that grep 2) any swap partition is not found by that grep so we could corrupt our storage if it remains mounted inside the freerunner and both exported with usb! a fix could be: - in storage-on script 1) modify the DEV_NAME with the name of the specific partition we want to export 2) umount it and really verify it's not mounted 3) modprobe g_file_storage (and we should add removable=y to the modprobe line) btw I'm not sure if this is acceptable by OSes others than linux, because in this way we expose a storage without a partition table. (I'll check this on a windows computer asap) ...else we could make a partition table inside the exported partition and use kpartx in the freerunner to read the storage (yes, it's like a matryoshka of partitions) bye, a. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
