[PATCH_v4 0/5] Private network request to ConnMan
by Guillaume Zajac
Hi,
Changelog from v3 is:
- Add private-network source/include
- ConnMan plugin is independant from emulator
- Each application that need VPN will pass a callback as argument
when private network is requested. This callback will contain the
private network settings.
Guillaume Zajac (5):
gatppp: Add new contructor to use external fd
private-network: add callback typedef drivers and settings
private-network: add request/release functions and new feature to
Makefile.am
emulator: add request/release private network calls
connman: add plugin in oFono to request request/release private
network

One API sure. Maybe on multiple services. Honestly, I don't see why
this would be such a burden for PA to watch 2 dbus services instead of
1. From oFono perspective it would make more sense to keep the HSP part
a separate daemon. I could be convinced otherwise if it is indeed a big
burden for PA...

Funny. "It is used but not suitable"?

Okay. But, just FYI, at the time there was no hw that could do such
on-the-fly conversions, so this use case wasn't considered/implemented.
There's really no reason why we couldn't extend our APIs to handle this.

True. In retrospect we probably should have used strings. But it was
assumed that vendor extensions would go via the Bluetooth SIG Assigned
Numbers facility. Anyhow, we can always add a 'Register2' method that
could take codecs as a string array or a combination of strings & ints.
And if Register2 was used, then use 'NewConnection2' with a signature
that supports passing in vendor codecs and whatever else that might be
needed.

There was no need, we automatically defaulted to using Wide band if
available. Third party codecs are a new use case (for oFono HFP), so
would require an API extension.

I think all of these are feasible to support under the current oFono
structure, either via plugins or API extensions.

New phonesim release including Qt5 support?
by Simon Schmeisser
Hi,
I'm a member of the Plasma Mobile team and we are currently trying to
get our messaging and phone stack working. Having a distribution
packaged version of phonesim available would simplify things a lot for
us. However distributions are currently dropping Qt4 support and there
has been no release since Jonah Brüchert introduced support for Qt5 last
year.
So in short, could you please do a new release of phonesim?
Thanks and regards
Simon

Failed to reconnect after 4G LTE signaling strength level is back
by Jupiter
Hi,
I am running ofono version 1.30 for uBlox SARA-R4 QMI on iMX6, it is
functional well, but there is one problem, it failed to be reconnected
when the 4G LTE signaling strength level is back to normal. Here is
what I tested:
- Connect antenna, it was running fine, network is connected.
- Remove the antenna, the network is down.
- Wait for a while, reconnect the antenna, the ofono could not
reconnect, the driver was still there.
- If I restart ofnono the connection would be back.
I tested the same sequence on SARA EVK which is not running ofono, it
is capable of re-register automatically.
Appreciate your sight comments if it is ofono issue or QMI issue or
something else, please find the attached debug file.
Thank you.
Kind regards,

Broken ofono 4G LTE network
by Jupiter
Hi,
While I was playing with ofono source code qmitmodem to debug LTE
re-register issue (in my another email), for some reason, it broken
ofono, there was not network IP address, I ran the AT manually in
command line, I can see the LTE modem is connected to the carrier, but
ofono could not talk to modem, there is no IP address. I reversed the
source code to remove changes, cleared the build, and rebuild the
image, but it is still broken, no IP, tried following command, it was
an empty string:
# dbus-send --system --print-reply --dest=org.ofono /
org.ofono.Manager.GetModems
method return time=1606601259.667554 sender=:1.2 -> destination=:1.121 serial=12
0 reply_serial=2
array [
]
Sorry, what could I be missing?
Thank you.
Kind regards,
