Re: NetworkTimeChanged signal doesn't seems to be working for Quectel
Hey Aleksander,
They have similar data but not in the same order for example +CTZE URC is
,,, so like this "+32",0,"2018/03/23,06:51:13" but for CTZU
it's like this ,, "+32","2018/03/23,06:51:13",0 and for
Cinterion the dst is optional
Thanks for the advice to get the signal, you are right I should use
libmm-glib shipped with ModemManager. I changed to this
GList *l = NULL;
int ret = 0;
GList *modem_list = g_dbus_object_manager_get_objects(G_DBUS_OBJECT_MANAGER(
manager));
for (l = modem_list; l; l = g_list_next(l))
{
MMObject *obj;
MMModemTime *modem_time;
obj = MM_OBJECT(l->data);
modem_time = MM_MODEM_TIME(mm_object_peek_modem_time(obj));
if (ret = g_signal_connect(modem_time, NETWORK_TIME_CHANGED_DBUS_SIGNAL,
G_CALLBACK(update_local_modem_time), NULL) <= 0)
{
DBG_PRINT("Failed to connect signal %s to modem %d\n", "network-time-changed
", ret);
}
}
Best regards,

What is the format of the +CTZE URC? is it similar to +CTZU? how are
they different?

Wondering, why not use the libmm-glib we ship with ModemManager
instead of manually creating the proxies and parsing the list of
updated properties?
E.g. you could:
* create a new MMManager with mm_manager_new()
* list the MMObjects it handles with g_dbus_object_manager_get_objects()
* get a MMModemTime interface object with mm_object_get_modem_time()
* listen to the "network-time-changed" signal

Re: NetworkTimeChanged signal doesn't seems to be working for Quectel
Hey Aleksander,
I do get the +CTZU notification, but it worked differently for quectel
because it doesn't receive the new time we need to check for +CTZE that's
the URC that we get when we receive notification that the time has been
changed.
For my use case, I would like to update my local time automatically on a
linux environment using modemmanager with quectel modules.
So right now I manage to change cinterion's function to process +CTZE
events and I receive the signal like this
GDBusProxy *proxy = g_dbus_proxy_new_sync(connection,
G_DBUS_PROXY_FLAGS_NONE,
NULL,
"org.freedesktop.ModemManager1",
modemPath,
"org.freedesktop.ModemManager1.Modem.Time",
NULL,
);
if (error != NULL) {
g_printerr("Error creating ModemManager1.Modem proxy: %s\n", error->message
);
g_error_free(error);
return 1;
}
g_signal_connect(proxy, "g-properties-changed", G_CALLBACK(update_local_time
), NULL);
}
But I'm not sure it's the best way to process the signal
Thomas,

Do you get +CTZU notifications in your modem? Right now I think we're processing these only for cinterion modules. Also, what is your usecase? I assume you're interested on the timezone information exclusively, right? -- Aleksander
NetworkTimeChanged signal doesn't seems to be working for Quectel
Hello, I am trying to get notification from Quectel when there is a time change, I see that there is a signal NetworkTimeChanged for this but when I looked at the code, I see that the signal is not being emitted for Quectel modules. Best regards,
