After debugging i found that most of gprs related issues are coming from
qtopia multiplexer. I decided to try to use external multiplexer with
qtopia. For the initial experiment i did:
1) compiled latest gsm0710muxd on debian (i know that there is
fso-abyss, but i got some problems on compilation, gsm0710 is much easer
to build, so i started with it).
2) Connected to phone using ssh and stopped qtmoko (/etc/init.d/qpe.sh stop)
3) started gsm0710muxd -v and requested virtual channel using dbus
dbus-send --system --print-reply --type=method_call
I got pts /dev/pts/3, and modified /opt/qtmoko/qpe.env with export
QTOPIA_PHONE_DEVICE="/dev/pts/3:115200". Also i disabled qtmoko
multiplexing in the /home/root/Settings/Trolltech/Modem.conf
([Mutiplexing] section, Active=no).
4) Then i started qpe. It started correctly, detected network, etc. Then
i requested another virtual tty (see #3) and started manually pppd on it.
From the first view - qtmoko works stable, gprs starts/stops much
better, no problems found so far. I want to test this for some time and
if it will work fine then i will try to build qtopia with
QMultiPortMultiplexer to use external mutiplexer.
