qmimodems: netreg properties CellId and LocationAreaCode sometimes not present
by Christophe Ronco
Hi,
With qmi modems I am using (quectel EG25, sierra MC7304), sometimes I
don't have CellId and LocationAreaCode properties in netreg properties
while I am registered. Example:
root@klk-wiis-020001:~ # dbus-send --system --type=method_call
--print-reply --dest=org.ofono /quectelqmi_0
org.ofono.NetworkRegistration.GetProperties
method return time=1561022820.781396 sender=:1.8 -> destination=:1.25
serial=96 reply_serial=2
array [
dict entry(
string "Status"
variant string "registered"
)
dict entry(
string "Mode"
variant string "auto"
)
dict entry(
string "Technology"
variant string "lte"
)
dict entry(
string "MobileCountryCode"
variant string "208"
)
dict entry(
string "MobileNetworkCode"
variant string "10"
)
dict entry(
string "Name"
variant string "SFR"
)
dict entry(
string "Strength"
variant byte 40
)
]
CellId and LocationAreaCode come from Current serving system info
indication in QMI protocol. These indications contains many parameters
and most of them are optional. What's happening here is:
- first serving system info indication indicates modem is registered,
gives CellId and LAC
- another serving system info indication indicates modem is
registered,and give no information on CellId and LAC
When the second indication is processed, ofono_netreg_status_notify is
called with lac and cellid equal to -1. As a consequence, corresponding
NetworkRegistration properties are removed.
Here are traces from ofono when problem occurs:

I see two ways to fix this problem:
1) modify QMI modem driver to remember LAC and CellId inside the driver.
When a notification arrives without CellId or LAC information, use
remembered information. The drawback of this solution is that these
information are remembered twice: in driver and in core.
2) modify core to add a way for drivers to say that these parameters are
not modified. The drawback of this solution is that it is a change in
core (even a change in core interface with drivers)
I assume that solution 1 is better of this problem is for QMI modems
only. I assume that solution 2 is better if some other drivers can have
the same kind of problems.
What do you think? How should I fix this problem? Will a change in
driver/core interface be helpful?

Christophe Ronco

[PATCH 1/1] ublox: detect and support LARA R2 series
by Jonas Bonn
---
Hi Krishna,
This patch isn't tested, but this is roughly what you'd need to get the
LARA R2 detected and running. After that, it's just a matter of going
through the details of where ofono has issues.
>From what I can see at a quick glance at the documentation, there's
nothing that particularly stands out here so I suspect things will
mostly just work. Give the patch a try and let me know how it goes.
Regards,
Jonas

[PATCH] xmm7modem: disabling reporting of intermediate results for CGDATA
by Antara Borwankar
Setting <connect_flag> in AT+XDATACHANNEL set command to 0. This will
disable intermediate result reporting of "CONNECT" and "NO CARRIER"
on control channel.
This resolves the issue of getting failure response for offline-modem
since "NO CARRIER" is received as result of AT+CFUN operation instead
of "OK".

[PATCH 1/2] xmm7modem: fix to activate context with cid zero
by Antara Borwankar
xmm7modem returns 0 as cid for default pdp context. Thus removing
check for last_auto_context_id so that context actvation can be
successful.
