Qtopia modem support
Message 1 in thread
Hello,
I use qtopia phone edition on HTC Blueangel, since start i got qtopia
error segfault after received AT commands ( this phone works with other free
phone software like gpephone, openmoko).
The first problem is coming from qatchat.cpp, for example if we
receive on atcmd channel something like "\n\r\n+CSCS : "HEX"\r\n\r\nOK\r\n".
I did not found any clean way to solve this.
This segfault is coming from void QAtChat::incoming() because we are
sending directly an empty buffer to processLine in case of 0xA is coming
first.
Now after some fix in phone kernel driver to avoid this case, send /
receive works fine until I execute function void
QModemPhoneBook::cscsDone( bool ok, const QAtResult& result ). When i come
here function updateCodec( name ); is ok, but after the QTimer::singleShot
did not success after the delay. The next AT command is never send and
qtopia stops here with an error message which say that qtopia can not join
qws server.
I hope my explanation are ok ;), if someone can help me to find out
what is wrong...
Regards,
Fabrice
