Telit ME910C1-WW not detected
by Dresdo Gabriele
Hello,
I'm new to oFono, I'm trying to setup a Telit ME910C1 with oFono 1.18 in our embedded system (ARMHF) with Debian stretch kernel 4.9.11 but list-modems returns no results.
I installed ofono packet using apt-get
I can send and receive AT commands to the modem using a terminal connected to /dev/ttyUSB1
I paste Log from ofonod -dn.
Any suggestion will be useful
Thanks
Gabriele

AuthenticationMethod can't be set to none
by jagernicolas＠legtux.org
Hi,
I have a device with a Quectel EC21 module. I have to make `ofono` working to connect internet using the lte. In the past, another company use `pppd` to connect internet. Using their scripts, I can connect internet when the module is set to avoid authentication (`noauth`). Now I try to do the same with `ofono` (I have no prior knowledge of ofono/connman and even the use of cell module).
According to `connman-api.txt`,
```
string AuthenticationMethod [readwrite]
Holds the PPP authentication method to use. Valid values are "pap", "chap" and "none".
Defaults to "chap".
```
I could set the value of AuthenticationMethod to "pap, "chap" and "none". For example,
```
context.SetProperty("AuthenticationMethod", dbus.String("pap"), timeout = 100)
```
will set the value. but,
```
context.SetProperty("AuthenticationMethod", dbus.String("none"), timeout = 100)
```
I got the following error,
```
org.ofono.Error.InvalidFormat: Argument format is not recognized
```
According to `lte-api.txt`,
```
string AuthenticationMethod [readwrite, experimental]
Sets the Method used for the authentication
for the default APN.
Available values are "none", "pap" and "chap".
Default is "none".
If the AuthenticationMethod is set to 'none',
no authentication is performed for the default attach
APN. Username and Password properties are ignored,
even if containing a valid value. If Username or
Password are empty, AuthenticationMethod is implicitly
assumed to be set to 'none'.
```
we can read that `If Username or Password are empty, AuthenticationMethod is implicitly assumed to be set to 'none'.`. I try that using the `connman-api`, but yet no internet.
Using the `lte-api` don't work much, It seems the field `AuthenticationMethod` is not present. When I print what come from `lte.GetProperties()` I got only the field `DefaultAccessPointName`,
```
DefaultAccessPointName
dbus.Dictionary({dbus.String('DefaultAccessPointName'): dbus.String('', variant_level=1)}, signature=dbus.Signature('sv'))
```
I don't see how I could solve this. Help would be appreciated.
Additionnal informations:
versions:
```
# ofonod -v
1.24
# connmand -v
1.35
```

org.ofono.AllowedAccessPoints not found on the interface_list
by JH
Hi,
I am running ofono for SARA-R4 Modem, systemd show many following
messages, does it need be concerned?
Interface org.ofono.AllowedAccessPoints not found on the interface_list
Sometimes the LTE was connected but sometime the LTE was not
connected, I try to figure out if there is any issues in ofono or not.
Appreciate your comments.
Thank you.

4G LTE connection stability with USB voltage requirement
by JH
Hi,
Apologies for cross posting.
I am running Yocto build image with kernel 4.19.75 on iMX6, the device
uses uBlox SARA-R4 4G LTE modem. I have an LTE connection stability
issue, it could connect to 4G LTE, then the connection was
disconnected between half an hour to an hour randomly, the error
messages were qmi_wwan of qmi_wwan 1-1:1.3: nonzero urb status
received: -71 and qmi_wwan 1-1:1.3: wdm_int_callback - usb_submit_urb
failed with result -19 for errors of EPROTO and ENODEV, many indicated
that kind of errors usually caused by insufficient USB voltage.
To diagnose it, I changed to use a DC regulated power supply to
connect USB voltage from a stable 5V DC regulated power supply, that
did help to stabilize the 4G LTE connection, the device has been
stable to connect to 4G LTE since yesterday (26 January AEST) morning
more than 24 hours which was not able to perform that stability if the
USB connected to a laptop or connected the device internal regulated
DC voltage from AC power supply.
What cannot convince to hardware engineers and what baffling me is
that I am also testing an image built from OpenWrt using network
manager netifd, it did not have LTE connection issue and it could
connect to 4G LTE much stable to use either USB power supply from a
laptop or device internal DC voltage from AC power supply. It does not
make sense if I say to the hardware engineer that device has power
supply issues. Why OpenWrt netifd is much stable than connman / ofono
in the same power supply conditions?
It seems to me there are subtle differences between connman / ofono
and OpenWrt netifd, could the connman / ofono require more rigid
stable USB voltage than OpenWrt netifd? Or could the OpenWrt netifd be
more superior than connman / ofono in terms of 4G LTE connections?
Appreciate your insight comments and advice.
Thank you.
Kind regards,

I don't have /sys/kernel/modules/ in the Yocto built file system, nor
can I find in my Ubuntu 18 laptop, my system is different from yours.

I changed to connect 5V DC power from a DC power supply, at first, the
error messages continually displayed, then it got more stable. As I
also stopped some applications, not quite sure which one make the
difference. Will have to spend more time to check it.
Thank you.

Where are ofono dbus paths for RSRQ and RSRP?
by JH
Hi,
I have been looking for getting RSRQ and RSRP values from ofono dbus
commands, but I could not find much information how to get RSRQ and
RSRP in debus-send commands, which following interface contains RSRQ
and RSRP? And how could I access thos RSRQ and RSRP in debus-send?
dict entry(
string "Interfaces"
variant array [
string "org.ofono.SmartMessaging"
string "org.ofono.PushNotification"
string "org.ofono.MessageManager"
string "org.ofono.LongTermEvolution"

GPRS - SIGABRT after context down - (SIMCOM 7600E)
by Viallard Anthony
Hi,
I have found a problem with ofono and the modem SIMCOM7600E. In a context with
a weak signal, sometimes ofono stops on signal 6 (SIGNAL ABORT).
I use the last version from git (commit
d90cfdd71cb9eb2b533a20e4aea6bbf79e79fd2e). I have some custom patches but it
should not play a role in the problem.
I have a little program that listen dbus signals from ofono and
controls it. The problem always occurs in the same way. A GPRS detach is detected by ofono
and it sends a PropertyChanged signal on org.ofono.ConnectionManager interface with
"Attached" set to false. Right after, the Attached property change to true and a DBUS signal is sent
by ofono. Therefore, my program sends SetProperty DBUS message on org.ofono.ConnectionContext interface with Active set to
true to enable the data connection again. But there, a signal SIGABRT is raised
in ofono. It is the layer DBUS that call abort() because an argument is NULL as you
can see below (in the stack #5, message is 0x0).

The line above is the last before ofono gets killed.
I can guess with the log and the code that there is a double hit of pri_activate_callback() whereas there is
only one DBUS request coming from my program (modemd):

Is there anyone have an idea to explain why this problem occur and how to fix it ?

Re: HSP/HFP ofono bluetooth support for Linux desktop
by Denis Kenzior
Hi Pali,
> Do you have a reasonable solution also for second issue?
>
HSP profile has always been a problem child. It isn't really all that
useful as a profile, and given how minimal it is, the right place for it
always seemed to be inside Pulse Audio itself. This is what Marcel & I
agreed upon back about 8-9 years ago anyway.
You are advocating that HSP is still useful, particularly with vendor
extensions. Which is fair enough, but now you have to figure out how
and where to put this support.
As mentioned earlier, one idea you can explore is to create a small
daemon (or maybe it can even be part of ofonod itself) that will handle
HSP client/server roles. See for example the dundee daemon that is part
of ofono.git. dundee handles Bluetooth DUN profile and might be a good
model / starting point for what you're trying to accomplish.
You can then implement the same API interfaces for setting up the HSP
audio stream as oFono does today (i.e.
https://git.kernel.org/pub/scm/network/ofono/ofono.git/tree/doc/handsfree...),
which would make PulseAudio's job much easier, since the audio stream
aspects would be essentially identical to HFP. If you're part of
oFono's tree, then in theory many implementation aspects could be reused.
If you want to provide some higher-level APIs for external applications,
then HSP specific interfaces (APIs) can be added as needed.
If you decide this is something you want to pursue, then I'm happy to
host this in the oFono tree.

Correct.

See oFono documentation on Connection Context.

/*
* The way this plugin works is following:
*
* powered -> SubscriberIdentity or Online = True -> gprs, context ->
* attached -> netreg -> ready
*
* Depending on the modem type, this plugin will behave differently.
*
* GSM working flow:
*
* When a new modem appears, the plugin always powers it up. This
* allows the plugin to create a connman_device. The core will call
* modem_enable() if the technology is enabled. modem_enable() will
* then set the modem online. If the technology is disabled then
* modem_disable() will just set the modem offline. The modem is
* always kept powered all the time.
*
* After setting the modem online the plugin waits for the
* ConnectionManager and ConnectionContext to appear. When the context
* signals that it is attached and the NetworkRegistration interface
* appears, a new Service will be created and registered at the core.
*
* When asked to connect to the network (network_connect()) the plugin
* will set the Active property on the context. If this operation is
* successful the modem is connected to the network. oFono will inform
* the plugin about IP configuration through the updating the context's
* properties.
[...]
I have only a vague memory on this topic, but I think to remember that
oFono will only show the CM if the APN was provisioned in oFono. Maybe I
have false memory on it.
Thanks,
Daniel
