Hi!

The following patch adds support for Wavecom Q2403 and Q2686.

We (the Osmocom team) are using these modems with ofono in our
testbed setup.

Any chance this can be applied to mainstream?

Thank you!

[PATCH] wavecom: add support for Wavecom Q2403/Q2686 modems

From: Pablo Neira Ayuso <pablo@gnumonks.org>

This patch adds support for voice calls and SMS for Wavecom
Q2403/Q2686.

The existing Wavecom driver in tree slightly differs from these
modems. Thus, it doesn't work work with them. We (the osmocom
team) are use these Wavecom Q2403/Q2686 modems in our testbed.

Can you please break this patch up, we prefer one patch for every
directory.  See HACKING document for patch submission guidelines.

Just how old is this modem and what version of 07.05 are you using?

For reference, 07.05 version 7.0.1 from July 1999:
"
+CPMS=?
+CPMS: (list of supported <mem1>s),(list of supported <mem2>s),
(list of supported <mem3>s)
"

So the comment should probably be changed to indicate that this modem is
just broken.

Are you sure you can't reuse the same behavior as OFONO_VENDOR_WAVECOM
quirk inside drivers/atmodem/sim.c?

e.g. in at_sim_probe():
        switch (sd->vendor) {
        case OFONO_VENDOR_WAVECOM:
                g_at_chat_add_terminator(sd->chat, "+CPIN:", 6, TRUE);
                break;

This is probably wrong, I suspect we need to add a generic function to
register (real) serial tty based modems.

Is there a way to just re-use the wavecom driver instead of creating a
brand new one?

Hi Denis,

First off, thanks for your quick review.

OK, I'll do it like that if you prefer it.

I think it breaks a bit of the logic of "one patch one new feature" and
it leaves the repository in intermediate state between patches, but
this is your project, you rule here :-).

Without it, the modem initialization does not complete.

You mean for both snprintf, right?

From: "3.2.2 Preferred Message Storage +CPMS" (TS 07.05 July 1999):

+CPMS=<mem1>[, <mem2>[,<mem3>]]

The brackets around <mem3> sound like it is optional thing.

Unless I'm missing anything I think the comment is fine.

OK, so you prefer this, right?

Yes, I remember to have tried that. That quirk didn't work for me
though.

I should have added some add_wavecom function instead.

I used that because I noticed that:

add_sim900
add_nokiacdma
add_tc65
...
and so on.

look the same. So I guess that it is indeed a good idea to remove
redundant code and provide some generic one.

I didn't find any cleaner solution I could like, but if you propose any
other solution, I'll make it.

That is a set operation, we're doing a support query.

I think we need to dig a bit deeper as to why, the VENDOR_WAVECOM
behavior seems to be addressing exactly this case.

If they are all the same, then adding a generic function is fine.

Right now to me it seems like the differences between the -Q version is
a slightly different set of quirks.  Can't we query the model / firmware
versions and set the quirks accordingly?

You're right, then it's a broken modem indeed.

I think the other wavecom vendor provides a different reply. I can add
a different quirk to at_cpin_cb instead and see how it goes.

Is there any facility that ofono provides to do this? If so, please
point to some existing code.

[PATCH] v2: support Wavecom Q2403/Q2686 modems

[pablo]

[-- Attachment #1: Type: text/plain, Size: 807 bytes --]

From: Pablo Neira Ayuso <pablo@gnumonks.org>

Hi!

This is the second version of the patch to support Wavecom Q2403/Q2686
modems. I've tried to address all comments from Denis Kenzior.

I've splitted the patch in two, one per directory directory as you
suggested.

Please, let me know if you find any issue with this patch.

Thank you!

Since this is a serial device, you can easily do something like this in 
your rules file:

ENV{OFONO_WAVECOM_MODEL}="Q2XXX"

This setting can then be forwarded to the modem driver by using 
ofono_modem_set_string(modem, "Model" (or Quirk, or whatever), ...);

There is no need to create a separate driver for the wavecom.

See add_ifx() for an example of this.

Please do this inside drivers/atmodem/sim.c?  In at_sim_probe() 
specifically.

Do something like:
vendor = 0;

if ofono_modem_get_string(modem, "Model") equals "Q2XXX":
	vendor = OFONO_VENDOR_WAVECOM_Q2XXX;

ofono_sim_create(...);
