USSD

Markatrafik

I used USSD services because they are simple and convenient. But in UT (UBports) dialler-app application just hangs when calling USSD service. Does this code work at all or not yet?

As I understand it, work has been done in this direction:

phablet@ubuntu-phablet:~$ find / 2>/dev/null | grep -i -e ussd
/usr/share/ofono/scripts/initiate-ussd
/usr/share/ofono/scripts/cancel-ussd
/usr/share/ofono/scripts/send-ussd
/usr/share/dialer-app/Dialogs/UssdProgressDialog.qml
/usr/share/dialer-app/Dialogs/UssdResponseDialog.qml
/usr/share/dialer-app/Dialogs/UssdErrorDialog.qml

My phone is Xiaomi Redmi Note 7 - maybe this is the problem and USSD does not work on this particular hardware, but MMS (and SMS) works fine, but in other application...

don't know much about USSD, just saw a fix that have been done few months ago. Do you have logs ( dialer-app or dbus ) ?

Markatrafik

@lduboeuf where can I find logs of dialer-app in the system? maybe I need to enable debugging somehow, and there is nothing useful in /var/log

Markatrafik

@lduboeuf ohh... sorry, I forgot about the dbus ...

@markatrafik you can see logs from the logviewer app, or in .cache/upstart/

Don't see much from dbus
Edit: we can see an error in dbus log. But i personally don't know where to look at Maybe someone know better ?

Markatrafik

@lduboeuf no information in the ~/.cache/upstart

Connection :1.224 (uid=32011 pid=20883 comm="dbus-monitor ") became a monitor.

Monitoring connection :1.224 closed.

But utility dbus-monitor say enough...

The USSD functions is not implemented yet

Maybe I don't understand something, but I can clearly see python scripts to onofo, for example:

phablet@ubuntu-phablet:~$ /usr/share/ofono/scripts/initiate-ussd
Usage: /usr/share/ofono/scripts/initiate-ussd [modem] <ussd-string>

also, the QML componets menu scripts for dailer-app:

phablet@ubuntu-phablet:~$ cd /usr/share/dialer-app/Dialogs/
phablet@ubuntu-phablet:/usr/share/dialer-app/Dialogs$ ls -al

What is missing from the system so that I can work with my ISP's USSD dialog menu? May be from terminal using python scripts?

USSD works fine on most of my phones (Xperia X, Nexus 5, MX4, Bq E5) so it's most likely an issue or missing implementation on your specific device model.

@kugiigi said in [USSD] (/post/48876):

Yes, I have no luck with this equipment, the echo is such that the other side hears itself after a second, like a parrot, calls can not hear - you can miss an important call, and so the USSD at the end...
I hope this can all be fixed, or is it easier to order another machine?

@kugiigi
Works on MX4 too.

I didn't even know about USSD, just decovered this with this thread ^^
Tested #123# from orange.

@markatrafik humm already heard the echo issue for some devices, here ?: https://forums.ubports.com/topic/5968/caller-echo?_=1617469387193

I tried to use the onofo python scripts directly. For a one-step USSD request from the shell everything looks good, the data is output to the console:

~$ /usr/share/ofono/scripts/initiate-ussd /ril_1 "*100#"
State: idle
USSD:  Current: 235.79, Limit: 300

But if a dialog is required, the answer appears on the screen, asks you to enter the number of USSD menu item, and press the button. If I click the button, the window closes and the script crashes with the following errors:

~$ /usr/share/ofono/scripts/initiate-ussd /ril_1 "*222#"
State: idle
Traceback (most recent call last):
  File "/usr/share/ofono/scripts/initiate-ussd", line 35, in <module>
    result = ussd.Initiate(ussdstring, timeout=100)
  File "/usr/lib/python3/dist-packages/dbus/proxies.py", line 145, in __call__
    **keywords)
  File "/usr/lib/python3/dist-packages/dbus/connection.py", line 651, in call_blocking
    message, timeout)
dbus.exceptions.DBusException: org.ofono.Error.Failed: Operation failed

So there is USSD processing in the system. Only for some reason it does not work. For example, there is no possibility to "call" a number beginning with an asterisk "*".

Is there any way to get this program code to work completely?
