[PATCH] qmimodem: fix roaming status report
by Christophe Ronco
Hi,
With a MC7304 modem and a roaming SIM card, Status in org.ofono.NetworkRegistration
properties ends up in "registered" instead of roaming.
Both AT command and qmicli indicates we are roaming.
What's happening is the following:
1) first QMI_NAS_SS_INFO_IND indicating we are registered contains a QMI_NAS_RESULT_ROAMING_STATUS parameter.
Parameter inside says we are roaming and qmimidem driver correctly reports status NETWORK_REGISTRATION_STATUS_ROAMING.
2) other QMI_NAS_SS_INFO_IND arrive, saying we are registered without QMI_NAS_RESULT_ROAMING_STATUS parameter.
Driver reports NETWORK_REGISTRATION_STATUS_REGISTERED.
Extract of traces with QMI binary debug interpreted (as far as I can...):

I don't know if this is a problem specific to MC7304 or even to my firmware version or if this is a normal behavior to have ROAMING_STATUS parameter only when status change from anything to registered.

Christophe

no connection after ofono restart while huawei modem connected
by Christophe Ronco
Hi,
I use a Huawei MS2372h-607. It is a classical AT+PPP modem. I have a
problem when I stop ofono while context is activated. When I restart
ofono (without unplugging the modem), I am not able to send any AT
command on Modem channel because this channel is still in data mode.
I made a patch to send escape sequence when gprs-context atom is
removed. It fixes the problem but I don't know if this is the right
thing to do.
Attached to this mail:
I/ reconnectError_01: traces of complete test (with debug and AT debug).
Test done:
1) board boot
2) Connection (success), start at line 1058:
connmanctl connect cellular...
3) stop ofono, start at line 1109:
/etc/init.d/ofono stop
4) start ofono, start at line 1348:
/etc/init.d/ofono start
5) Connection (error), start at line 2018:
connmanctl connect cellular...
I don't have PPP debug in this trace but here is what happens at PPP
level when Ofono is stopped:
ofonod[944]:
../ofono-1.24/drivers/atmodem/gprs-context.c:at_gprs_detach_shutdown() cid 0

ofonod[944]: ../ofono-1.24/src/gprs.c:gprs_unregister() 0xc10d90
Terminate request is sent and then gprs-context atom is removed before
Terminate Ack is received.
II/ 0001-PPP-send-escape-sequence-when-ofono-dies.patch
The patch I made to fix the problem. The idea is to immediately send
escape sequence when removing gprs-context atom. This patch is not ready
to be sent (at least it must be split in two patches). Can you tell me
what you think about this patch?
Best Regards,
Christophe Ronco

[PATCH] plugin: Don't unload external plugins too early
by Slava Monich
Plugins may reference data structures allocated by each other.
They all need to be deinitialized first, only then it should be
safe to unload the libraries.

[qmimodems] gprs context provisioning versus automatically discovered contexts in LTE
by Christophe Ronco
Hi,
I am doing a test with a 4G SIM card with APN set in provisionning. I
've recently upgraded my Ofono version to 1.23.
My card gets LTE attach quickly, before it gets ServiceProviderName from
SIM card.
So ofono_gprs_cid_activated is called by get_lte_attach_param_cb
(drivers/qmimodem/gprs.c) and a context is created with APN discovered
in get_lte_attach_param_cb.
Then SIM ServiceProviderName is discovered and provision_contexts is
called. Another context is created with APN from provisioning file.
I end up with 2 contexts using same APN or different APNs, depending on
what I wrote in my provisioning file. I attached logs with same APN case.
In messages_02.txt:
- ofono_gprs_cid_activated is called at line 681
- __ofono_gprs_provision_get_settings is called at line 753
I end up with two contexts (properties summary in gsmdiag_02.txt).
Another strange thing in ofono gprs file for this SIM card:
root@klk-lpbs-06029C:~ # cat /etc/network/ofono/208013004789734/gprs
[Settings]
Powered=true
RoamingAllowed=false
[context1]
Name=orange-mib
AccessPointName=
Username=
Password=
AuthenticationMethod=chap
Type=internet
Protocol=ip
[context2]
Name=Internet
AccessPointName=orange-mib
Username=
Password=
AuthenticationMethod=chap
Type=internet
Protocol=ip
Context 1 has no APN. I don't know what would happen if I restart Ofono
and gets attached on 3G. I don't know if this is a bug or not.
Here are the "problems" I saw. And I don't know what to do in this case.
I mean I don't know what result I should have.
What should happen if context information are the same in provisioning
and from network discovery? Maybe only one context?
What should happen if context information are different in provisioning
and from network discovery? Creation of 2 contexts and 1 gets
automatically connected? Disconnection of the automatically connected
context and creation of context using information from provisionning?
Provisionning ignored?

Christophe
