Re: Implementing support for a new modem- how to?
Hi Arun,
We are working with this type of modem, and would like to submit
patches to oFono. We found that we have to make few modifications to
some of the AT command responses and also may have to introduce to
support for a few new commands.
We found that in network registration sms, call meter and gprs there
are few AT command responses which differ from what is available in
the generic AT modem of ofono. There are few new commands to be
supported in network registration, gprs context etc, in order to
support this modem.
Do we need write new atom drivers even though the change is only in
one of the AT command response?, or can we use the vendor variable
(where ever available) to include this, as part of the generic at
modem drivers?
What is the recommended way to implement support for such a modem, so
that we can start submitting patches?
there is no generic answer to this. Until you post patches and show us
details on what is different from the GSM AT command specification this
is all speculations.
However there are two ways:
a) Write a new atom driver
b) Use the atmodem atom driver with a vendor quirk
In a lot of cases we just do vendor quirks. Check the source code for
examples. But again, until we have more details, I can't tell what is
the correct approach for your specific modem.

Marcel
