I was looking at this code earlier while I was seeking a way to trace what is
happening. That is when I was trying to figure out the chat command.
See my reply to Timo [1] for some searchings on the specification.

This is what I want to trace, but I cannot see how to do it :)
I am not clear on whether this is a QtMoko bug or a GTA02 bug, or a
combination of the two, so I have changed the subject to reflect this.
Do other distributions on the GTA02 have this bug ?

After a few seconds this dialogue will disappear and the correct date and time gets populated. I am trying to replicate this now, but the phone will not loose the date/time. I know it happened when I changed networks earlier this month. I went from Telstra to Optus, and it has happened for me on both networks. I figure they both implement NITZ in full. Specification wise, the wikipedia page [1] indicates it is not only timezone setting information. I also get a hit on www.etsi.org when searching for "nitz specification" that references Universal Time [2]. One of the wiki sources indicates the implementation is optional. However searching on "nitz universal time specification" gets some clarification on the issue: not only is it optional, different manufactures have different interpretations [3].

FWIW, from a quick look at
devices/neo/src/plugins/phonevendors/neo/vendor_neo.cpp, I see that the
suspend code includes
// Turn off timezone notifications.
chat("AT+CTZR=0");
chat("AT%CTZU=0");
and the resume ("wake") code includes
// Turn on timezone notifications again.
chat( "AT+CTZR=1" );
chat( "AT%CTZU=1" );
and that the code for a CTZU response appears to handle both date/time
and timezone:
void NeoModemService::ctzu( const QString& msg )
{
// Timezone information from the network. Format is
"yy/mm/dd,hh:mm:ss+/-tz".
So maybe I was wrong about time and timezone being separate.
Also note that
(1) there could still be missing bits of support higher up, for actually
doing anything useful with this information
(2) I wonder if it's also necessary to do the "Turn on" actions when the
phone first boots up?

Adam, I do not know the details of the distribution you are using, but I could imagine that the part of the software which controls the modem is 'eating up' the responses of the AT cmds you are sending down with chat(1). Concerning the time update, I'm using ntpdate(1) to get the correct time from Internet. matthias -- Matthias Apitz | /"\ ASCII Ribbon Campaign: www.asciiribbon.org E-mail: g...@unixarea.de | \ / - No HTML/RTF in E-mail WWW: http://www.unixarea.de/ | X - No proprietary attachments phone: +49-170-4527211 | / \ - Respect for open standards ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
GTA02 Setting time from phone network using NITZ ?
I have a GTA02 which I acquired a few years back and until now I have not really done anything with it. Now I want to use it as my main phone. The automatic setting of the date/time from the providors network (in this case it is Optus) does not work in qtmoko. The provider does support this as I have a another phone that gets this information. I see there is an old bug from the Nokia days: http://docs.huihoo.com/qt/qtextended/4.4/release-4-4-3.html BUG 231983 According to http://www.scribd.com/doc/30428306/54/AT-CTZU-Automatic-Time-Zone-Update I should be able to chat to the modem to get some information. But the following command does not return anything: root@neo:~# chat -vse '' 'AT+CTZU=?' '' '' > /dev/ttySAC0 < /dev/ttySAC0 send (AT+CTZU=?^M) send (^M) syslog shows: Jan 1 08:13:45 neo chat[1109]: send (AT+CTZU=?^M) Jan 1 08:13:46 neo chat[1109]: send (^M) Is there a way to automatically log the AT chat commands ? Do I have the correct /dev/tty ? More generally, is this a problem with the calypso firmware, or qt extended / qtmoko or something else ? ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
