+ adding ofono mailinglist as it may be of interest
Point is, that I am trying to run the u-blox on ofono+connman and
had/have some questions regarding the setup.
I compiled the git version of the ofono for a freescale vf610 board with
an onboard ublox usb adapter and got quite far.
A manual setup on pppd+peer+provider+chat script gave me a clean
internet connection.
Now I want to integrate that with ofono/connman. I got ofono finding the
module, advertise it as a cellular technology to connman, but no service
is showing up.
I will go on setting up the umts high throughput profile.
So the rest of the story can be found below!
@Dragos:
without any changes, I got
lsusb:
1546:1146 U-Blox AG (which is high performance?)
online modem runs without any complains, but without any changes
root@colibri-vf:~/test# ./online-modem
Setting modem /ublox_0 online...

Hi Jörn,
Can we take this discussion to the connman/ofono ml? Other people
might find this useful.

Hi Dragos,
I got python to work for the test scripts, this is what it gave [1]. I believe
I am just a minute away ..
Good.
I got the connection up and running on a manual (old fassioned) way with pppd,
chat and provider script. However I am not an expert on ofono/connman yet (but
trying hard ...).
I firstly wanted to use 2g/3g with high performance mode (as I saw your effort
has been put on this point, right?). I am rather not sure, how to configure
that without having a connman service.
The AT Commands Examples [1] documents that (USB configuration section).
You should change the mode manually. A successful set will yield the
following ids from lsusb:

Hmm, not sure what the roaming state is. But it looks like it's not yet
ready to attach the gprs context (Attached is not yet 1).
Can you try running online-modem script? Maybe it will work.

Is there something else to activate?
I am actually trying to transfer the python test scripts to my embedded system,
but there is no python3 available on open embedded, and so I do not have dbus
access from there :(.
The python scripts are really useful. Especially to investigate the state
of oFono. See list-modems and list-contexts.
I am not sure, what a context is...
A context is oFono's concept of a "connection to internet" :). For 2/3G there
are 3 states to enable the internet connection:
* enable the modem (done by connman in your case)
* register to the network (might be done by connman, list-modems will
help you debug that)
* activate context (sometimes done by connman, list-contexts will
tell you the state of the context)

Hi Dragos
I saw, you wrote some code for the toby ublox modem on ofono.
I am actually setting up an embedded system using that modem and got some
issues with the latest ofono git and connman.
The ofono deamon seem to recognize the modem and connman shows the cellular
technologie but there is no service shown on connman.
Are you using LTE or 2/3G? If 2/3G, did you activate the context? Connman
will create a service for every activated context.
So, are you using LTE or 2/3G? And also, which version of Toby are you
using and in which mode (high throughput, fairly compatible or backward
compatible). We used only high throughput mode so far.
Thanks
Once again, let's move the discussion to the mailing list please.
