Re: Data call (aka CSD) with QtExtended
Hi Ed,
Just try to initiate data call but no success.
There is a strange symptom that is: If I use the same SIM but on other
mobile (Motorora Z8) I can hear the far end land-line modem sound respone
but if I use FR to call the same modem: (1) via AT commands I see no
response, both sound and response modem characters so can not use
expect(CONNECT) with ppp (2) via GUI, it drop the call.
My FR can do voice call normally.
Do you have any way to debug the status of data call while using AT
commands? I just know +CEER but it does not give much info.
Cordially,
Tuan

Re: Data call (aka CSD) with QtExtended
Hi Tuan,
Strange that no connection is made to the landline modem.
you see no response, but dou you see the at commands echoed back?
if not use ate1 to see the responses.
you can restart /usr/sbin/gsm0710muxd with the -v option and use logread
to see what is send and received from the modem.
If you use the motorola to call your FR, can you pick up the call with
the ATA command?
Do you see a ring message?
Good luck !

graphical nethack for freerunner (alpha version released)
http://cc.oulu.fi/~rantalai/freerunner/nethack/ Warnign: Not yet playable! At last I got inspiration to compile graphical Nethack for Freerunner. It is actually gtk2-hack ported to maemo. So it has dependeries on libosso and libhildon, but I got them compiled from OpenEmbedded. Tested with OM2008.12. Nethack-maemo is almost keyboardless. Nokia Internet Tablet has couple of hw-buttons, so this is not yet playable, because Freerunner doesn't have these buttons. And element-layout must be changed, maybe some tuning of icons, font size etc. And there are two sets of graphics, but I got only uglier to work. So let me know if you are interested in play this game someday, or even better if you want help me to get this happen (help on planning is important as help on coding). -Aapo Rantalainen ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

test result of battery current against display brightness and GPS power mode
Because display and GPS chip may be powered on for a long while, I
choose to test them here.
Phone is GTA02v5. Distribution is latest SHR unstable, with almost 0% CPU load.
No devices(WIFI, GSM, etc) opened before this test. Battery capacity
is about 88%.
My test method is, for example: set display background light to 100%,
then get battery current every 5 seconds for a while...
To power on GPS chip: write 1 to file
/sys/bus/platform/devices/neo1973-pm-gps.0/pwron.
To set brightness: write (brightness_percent / 100 * 255) to file
/sys/class/backlight/gta02-bl/brightness
To get current battery power: read file
/sys/class/power_supply/battery/current_now.
- It seems kernel update this file every 30 seconds
- the output unit is uA.
To enable/activate FixNow sleep mode: write UBX binary messages
CFG-FXN and CFG-RXM to /dev/ttySAC1.
- when activate, write dummy packet and RXM-POSREQ message:
{ 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 0xB5,
0x62, 0x02, 0x40, 0x00, 0x00, 0x42, 0xC8 }
Here is the results:
1. when GPS chip is powered off, test brightness vs. battery current:
* brightness = 100%: battery current ~= 203 mA
* brightness = 75%: battery current ~= 153 mA
* brightness = 50%: battery current ~= 116 mA
* brightness = 25%: battery current ~= 101 mA
* brightness = 0%: battery current ~= 95 mA
2. when brightness is 0%, test GPS power state vs. battery current:
* GPS normal power mode: battery current ~= about 144 mA
* GPS FixNow sleep mode: battery current ~= about 97 mA when it goes to sleep
* GPS FixNow sleep mode: battery current ~= about 146 mA when it is waken up
From test #1, (assume battery voltage is constant) we can see:
1) the naked OS with almost zero CPU load and 0% brightness consumes ~95 mA.
2) brightness greatly affect battery life, 100% brightness consumes ~108 mA
3) comparing to 100% brightness,
25% brightness saves 95% power,
50% brightness saves 80% power,
75% brightness saves 55% power
From test #2, we can see:
1) GPS chip consumes about 50 mA when run in normal mode
2) GPS chip consumes near 2 mA when it goes to FixNow sleep
I've been testing FixNow for a while. Now I doubt whether it is useful
for phone users, because:
1) to save power, we can't frequently wake up FixNow from sleep,
because on each wakeup it tries getting fixes for a while then goes to
sleep (off).
2) the position data is not accurate just after wakeup, so we have to
poll for a while, if we're lucky enough we get good fix.
I think, FixNow can only be possibly used in this kind of scenario on
Freerunner:
-- For a long trip, we need log position data (say every 3~5 minutes,
I think it's bad to set the frequency less than 1 minute).
A logger sets GPS chip to FixNow mode, frequently wakeup it to get fix.
To save power, we set display brightness to 0% by locking screen,
but OS still consumes 95 mA, leaving at most ~10 hours battery life!
How to utilize FixNow feature?
Can we make the power consumption of naked OS down to tens of mA?

You must have done something wrong. I frequently test power comsumption
and I get 54 mA on a fully charged battery, dropping slowly as the battery
discharges[1] and nearly 20 hours battery life.
FWIW, I test with this command on a Debian installation:
sleep 120 cat
/sys/class/power_supply/battery/{status,current_now,voltage_now,capacity}
[1] It's supposed to be the other way around - current increasing as the
battery discharges - but there's a current leak somewhere. It was down to 46
mA not too long ago with a kernel from the andy-tracking branch.
