[Kde-hardware-devel] MMQt - SMS

[Jan Grulich]

Hi Daniel,

I would try to check whether there is a problem in ModemManager or in the 
communication between ModemManager and MMQT. 

1) Check whether ModemManager really sends signals about received messages. 
You can use dbus-monitor to watch ModemManager activity over dbus.

Use:
dbus-monitor --system "type='signal',sender='org.freedesktop.ModemManager1'"

2) If you see ModemManager sending signal Added()  from 
org.freedesktop.ModemManager1.Modem.Messaging interface then there is probably 
problem in MMQT. You can try to put some debug output to onMessageAdded() slot 
in modemmessaging.cpp from MMQT library to see what's going on and whether the 
slot is called.

I hope this will help to identify where is your problem.

Regards,
Jan
