Saman, we've never investigated using USSD or the use of the ofono
SupplementaryServices API.  You mention Bluetooth, however, and as far
as I can tell from some searching, USSD does not seem to be exposed via a
Bluetooth profile (MAP is only for SMS to my knowledge), and the USSD code
I see in the ofono source tree all seems to be in drivers for specific
modem hardware.  That likely means you cannot do what I think you're
asking, or if it is somehow possible likely not with BlueZ + ofono.
