Ok, so indeed two issues:
1) Applications unable to retrieve network status of ofono based modems:
That's because the only way to retrieve that information, currently, is indeed
via ofono:
src/systeminfo/linux/qnetworkinfo_linux.cpp:
===
...
case QNetworkInfo::GsmMode:
case QNetworkInfo::CdmaMode:
case QNetworkInfo::WcdmaMode:
case QNetworkInfo::LteMode:
case QNetworkInfo::TdscdmaMode:
#if !defined(QT_NO_OFONO)
qDebug() << "getting network status for modem";
if (QOfonoWrapper::isOfonoAvailable()) {
if (!ofonoWrapper)
ofonoWrapper = new QOfonoWrapper(this);
QStringList modems = ofonoWrapper->allModems();
if (interface < modems.size()) {
QString modem = ofonoWrapper->allModems().at(interface);
if (!modem.isEmpty())
return ofonoWrapper->networkStatus(modem);
}
}
#endif
break;
===
Status, following the oFono doc:
string Status [readonly]
The current registration status of a modem.
The possible values are:
"unregistered" Not registered to any network
"registered" Registered to home network
"searching" Not registered, but searching
"denied" Registration has been denied
"unknown" Status is unknown
"roaming" Registered, but roaming
Which is what we want indeed.
Now before we go and implement another method to provide the information
we need, why do you think GetProperties reveals too much information for
the apps?
2) The issue with Mako, when ofono is disabled, is that it returns
NoNetworkAvailable for wlan because mako's driver fails to report the proper
signal via /proc/net/wireless. As a quick workaround (due the broken drivers),
I'd suggest trusting only on
/sys/class/net/wlan0/carrier instead.
Follows the patch:
