Is USSD support is available and functional in ofono latest version?


I found the support in SupplementaryServices interface and I am able to read
the properties from this interface, but I am getting error when try to call
"Initiate" method,
from the definition of "Initiate" method in ussd.c found that out arguments
are "sv". below is the test code.

gchar *str=NULL;
GValue val={0,};
g_value_init(&val,G_TYPE_STRING);
dbus_g_proxy_call (proxy,
"Initiate",&error,G_TYPE_STRING,"*#43#",G_TYPE_INVALID,G_TYPE_STRING,&str,G_TYPE_VALUE,&val,
G_TYPE_INVALID);

if above code is executed  , the error is
" GLib-GObject-WARNING **: gvalue.c:185: cannot initialize GValue with type
`GValueArray_gchararray+GHashTable_gchararray+GValue__', the value has
already been initialized as `gchararray'

Couldn't convert argument, expected "GValue" "


and in generate_cw_ss_query_reply callback , message signature is "(sa{sv})"
so tried with

GArray *list;
GHashTable *OUT_arg0=NULL;
dbus_g_proxy_call (proxy,
"Initiate",&error,G_TYPE_STRING,"*#43#",G_TYPE_INVALID,
                                dbus_g_type_get_struct ("GValueArray",
G_TYPE_STRING,
                                dbus_g_type_get_map ("GHashTable",
G_TYPE_STRING, G_TYPE_VALUE),G_TYPE_INVALID),
                                &OUT_arg0, G_TYPE_INVALID);

but it is returning error " Expected D-BUS struct, got type code 's'"

can any body please tell me the correct return types.

in both cases ofono is getting response from phonesim.

and no proper documentation is available for USSD support .


can anybody please help?

thanks
sk.

Look at doc/supplementaryservices-api.txt for a detailed description of
the API. And test/test-ussd is an example in Python on how to use it.

Hi,

a gentle reminder that we are not allowing top-posting on this mailing
list. Don't do it.

it is in the GIT repository, but was never included in the tarballs. I
fixed that now.
