The 3607GW based modems are well supported by oFono, however we have not
tested all of the possible ones.  So assuming that you have installed
ofono.rules file correctly the only other problem might be that your
device manufacturer has named the port / network devices slightly
differently from other manufacturers.

See plugins/udev.c add_mbm() for more details.  I see that we definitely
do not cover the "Broadband Network Device" case that your modem is
reporting.

Running ofono with -n -d 'udev*' command line options should help you
quickly diagnose the issue.

Problem detecting/using wwan0 modem

[ofonoconn]

[-- Attachment #1: Type: text/plain, Size: 2479 bytes --]


Hello list,

when using distros integrating network-manager, I can connect to the
Internet using my GSM/GPRS/UMTS WWAN modem and would like to be able
to do so with Linux distros (MeeGo) which integrate ofono and
connman. This is not very well documented, so please help.

GOAL
----
I want to be able to select from between eth0, wlan0, and wwan0
from the ofono/connman connection applet in MeeGo.

PROBLEM
-------
Ofono (or connman, not sure which) presents connection options after
detecting that wired and wireless ethernet interfaces exist. In my
netbook, no option to use the F3607gw (labeled Hewlett-Packard below)
WWAN modem device wwan0 is available.

by udev, maybe.  However, it won't be detected by oFono without a
properly setup udev rule.

Your modem (at least according to your earlier dmesg log) is reporting
the ethernet device as: Mobile Broadband Network Device

oFono has so far only released version 0.50 upstream, so I'm not sure
how Meego is making 0.58 ;)  Try putting plugins/ofono.rules from
ofono.git into /etc/udev/rules.d, re-plugging your dongle and starting
oFono with -n -d 'udev*'

Nope, sounds like the rules are not installed or the card is not
inserted (but I assume it is built-in, so the latter is probably not it)

That's what I figured.  The rules seem to be OK, so the udev detection
code in plugins/udev.c:add_mbm is not finding your modem.

Try starting oFono with

ofonod -n -d 'plugins/udev*' (sorry, I messed this up earlier)

and report the output

Based on the output above, the udev plugin needed to be modified to
detect the HP version of the MBM modems.  The change can be found in
commit: 6a2847f7aba5d84b06940ee29300d4b6fd31d682.  I'm also attaching
this patch for your reference.  Please report back if this solves your
issue.

The vanilla MeeGo distribution has:

  meego$ find /etc/udev/
  /etc/udev/makedev.d/50-udev.nodes
  /etc/udev/rules.d/70-persistent-cd.rules
  /etc/udev/udev.conf

and 'ofono-test-0.58-1.4.i586' only.

...but:

  meego$ ls -1 /dev/.udev/db/*an*

  /dev/.udev/db/net:wwan0

...so even without a ofono.rules, the modem is being detected?

If the missing 'ofono.rules' is not the problem, then I'll likely
have to add a new entry to the list of devices in the add_mbm()
function. Not sure how to determine the name of my device though.
Huawei, sierra, nokia are there, but no 'ericsson'.

After booting I killed the 'ofonod' process and restarted it as root
with the arguments -n -d 'udev*', but no output has appeared yet.
How do you expect this to help, should I send USR1 signal or do
something else?

Thanks for helping,
Michael

Hmmm.

Is 'cdc_ether' the driver string entry which is missing from

comes up empty on my netbook?

Its not a dongle, rather a Mini PCI-E  that I semi-permanently
installed on the motherboard.

It's installed correctly and a SIM card is plugged in. This
exact configuration works perfectly when booting Ubuntu (with
network-manager) on the same netbook.

Okay but we were looking in the wrong place...

  meego$ ls /lib/udev/rules.d/*ofono*
  97-ofono.rules

  meego$ grep -i '03f0.*271d' /lib/udev/rules.d/97-ofono.rules
  # HP hs2330 Mobile Broadband Module
  ATTRS{idVendor}=="03f0", ATTRS{idProduct}=="271d", ENV{OFONO_DRIVER}="mbm"

I've confirmed that the PID/VID of my butchered (by HP) Ericsson
modem matches this entry above, which is in my udev rules directory.
It's probably the reason that /dev/.udev/db/net:\wwan0 is getting
created by udev at all.

So with this new information what should I be doing to correct this
problem? It seems to me that the ofono sources are not missing
anything.

  meego$ /usr/lib/ofono/test/list-modems
  meego$

...shouldn't that command be showing my modem?

Regards,
Michael

Wow that's great. I haven't built a new package yet to test your
patch, but if I understand the logic correctly it should solve
the problem. I'll let you know what happens after I'm done.

Okay bad news. I patched version 0.50 with the logic above and
nothing has changed. After installing version 0.50 with the patch
applied (checked to make sure) I get the same debug output and
/usr/lib/ofono/test/list-modems gives no output.

Is there some other test other than list-modems that I should use?

Incoming patch HS2330 detection, plugins/udev.c

[Michael Schloh von Bennewitz]

[-- Attachment #1: Type: text/plain, Size: 1380 bytes --]

This patch is assembled according to discussions on #ofono
irc.freenode.net and mailing list thread 'Problem detecting/using wwan0
modem' in June 2011, after comprehensive guidance from Denis KENZIOR.

Denis had already modified plugins/udev.c in git commit
6a2847f7aba5d84b06940ee29300d4b6fd31d682 to correct detection of
OEM Ericsson F3607gw modems relabeled by HP and sold as HS2330.
Because some (or all?) HS2330 modems contain flawed text identifiers
containing strange (probably erroneous) binary sequences in place of
the ASCII space '\x20' character, the previous commit is incomplete.
The following logic detects the modem properly, by comparing binary
data as well as ASCII text values.

Great, thanks alot. But most of all, thanks for the great work
on ofono in general. I think it's pretty good software and a
good project.

It might interest you that I made a feature request 20386 on the
MeeGo bugtracker [1][2] today to include PIN entry logic in the
MeeGo network panel. Not sure how far this request will go or if
they'll (gulp) ask me to do it myself... I'm still unclear on the
boundaries and coupling between ofono, connman, and the UI pieces
like the MeeGo network panel.

It's only relevant because we had discussions about this on IRC.

we do not really work on MeeGo network panel related UI details, but in
general there needs to be a split between network generic tasks and
technology specific ones. Similar to that we have a Bluetooth panel for
pairing etc.

So would expect to see a cellular panel that allows to enter the PIN
code and configure the APN settings. Since APN settings are oFono
specific and have nothing to do with ConnMan.

I leave this all up to our UX designers :)

Regards

Marcel

Well I don't think you mean 'panel' here, because they are rather
large overreaching components. Putting cellular information in its
own panel would only be a good thing if there's much more to it than
the APN typically used. Maybe I'm too new to 3G, but it seems to me
that the cellular config can be part of the network panel just as
Wifi information is as well.

Bluetooth probably has its own panel because of potential file
transfers, pairing, tethering, various profile activity... It's
a lot more to configure than just the APN of a cellular connection.

So that's why it might be good to put the PIN entry textedit just
next to the DHCP/Static selector of the cellular device. It would
be a intuitive place to look for it at least.

It would help to know just who that is and where or how they
communicate with the community.

Are these UX designers officially part of the ofono project or
the meego project? When you say 'our UX designers' do you mean
that 'ofono developers maintain the MeeGo network panel code'
as well?

Michael

Hi Michael,

I'm Nicolas Paccou, I'm in charge of validating the changes applied in new
oFono release.
Unfortunately, I have not the hardware to be able to regress your patch.

I wanted to know if you have tested your patch on HS2330 modem ?
If yes, can you tell me if the result is ok ?
If not, do you able to test it and tell me the result please ?

Thanks,
Nicolas

Subject: Incoming patch HS2330 detection, plugins/udev.c

This patch is assembled according to discussions on #ofono
irc.freenode.net and mailing list thread 'Problem detecting/using wwan0
modem' in June 2011, after comprehensive guidance from Denis KENZIOR.

Denis had already modified plugins/udev.c in git commit
6a2847f7aba5d84b06940ee29300d4b6fd31d682 to correct detection of
OEM Ericsson F3607gw modems relabeled by HP and sold as HS2330.
Because some (or all?) HS2330 modems contain flawed text identifiers
containing strange (probably erroneous) binary sequences in place of
the ASCII space '\x20' character, the previous commit is incomplete.
The following logic detects the modem properly, by comparing binary
data as well as ASCII text values.
