thanks for the reply. I was not sure about the voice call features of
the modem. Now when I searched the answer I found out that the modem
does not in fact support voice calls.
Yes, oFono's current implementation does not understand hardware specifics.
The current atmodem driver assumes a fully featured modem with perfect fluency
in 27.007 & 27.005. Obviously this is wrong for real modems. Mostly this is
because we were concentrating on getting the high level features working,
before delving into hardware specifics.
I did not realize this at first, because ofono offered the possibility
for voice calls (loaded for example the VoiceCallManager interface). For
SMS ofonod says
ofonod: SMS not supported by this modem. If this is in error
please submit patches to support this hardware
however the modem has a support for SMS, which I also tested with the
windows drivers that were delivered with the modem.
I've seen this reported at least twice now. Which means that my SMS support
detection in atmodem driver is probably not quite correct. Would you be able
to report at which point in the drivers/atmodem/sms.c initialization that this
Maybe there could be similar "not supported" feature for
the voice call
27.005 defines at least some rudimentary way to detect whether SMS is supported
by the modem or not. Unfortunately 27.007 doesn't have an equivalent for
voice calls. The generic driver will do its best to figure out what is
supported or not supported, but it will be up to the device-specific driver to
have the final say.
