[Kde-hardware-devel] MMQt - SMS

[Daniel]

Hi Jan,

I ran the dbus-monitor in order to watch the dbus traffic but there is
nothing there while I am sending the messages.

If i ran:

# disable the modem
mmcli -m 0 -d

and after that

mmcli -m 0 -e

all messages that were sent will be received at same time and the signals
are emitted in the dbus, as follows:

signal sender=:1.3 -> dest=(null destination) serial=197
path=/org/freedesktop/ModemManager1/
Modem/0; interface=org.freedesktop.ModemManager1.Modem.Messaging;
member=Added
  object path "/org/freedesktop/ModemManager1/SMS/5"
  boolean true

When the signal is emitted my application works perfectly, so the MMQt is
doing the right job.

So, I am thinking that there is a problem or in modem driver or in modem
manager.

Thanks in advance.
