Please keep in mind that oFono is only signaling settings to an external
component (e.g. a connection manager like ConnMan).  So route
assignment, DNS entry assignment, etc are not done by oFono.  oFono only
brings up the interface and assigns the local IPv4 address.

These steps are fine, is your context pre-configured already?  What does
the output of list-contexts look like?

Generally you do this _before_ activate_context and you give parameters
for the context settings.  e.g. create-internet-context
"apn.operator.com" "username" "password"

The route assignment seems fine, I assume you're using connman?

I see you're on AT&T.  What APN are you using, the WAP-only APN or
something that allows actual internet connections?

I should have clarified this a bit. I'm putting together a Board Support
Package (BSP) for the Yocto Project. This involves a kernel config,
sometimes some kernel patches, and listing a set of packages to be
installed.

I have ofono ofono-tests connman and connman-tests. I tried the
connman-gnome UI, but the 3G modem doesn't appear in the UI. I tried the
connman-tests tools which does list the modem in services, but the
connect command times out. I then tried the ofono-tests scripts as
described below. The system obtained the IP address after the
create-internet-context command. As far as I know, connman was not
involved (the 3g connection didn't appear in the connman-gnome UI
afterward).

How can I tell? Is there some permanent state that gets recorded after
I've run through the above once?

After a reboot, I see the following:

$ ./list-contexts
[ /mbm_0 ]

OK. I'm new to setting up 3G connectivity. I'm using a prepaid AT&T go
phone sim card. I have successfully sent and received SMS messages from
the device without having to setup any kind of pin or other
authentication credentials. Are these credentials always required - even
with SIM cards? If so, how do I go about discovering what they would be?

If I'm understanding this correctly, there exists one context for the
mbm_0 modem after I ran create-internet-context, and it is no longer
necessary to run create-internet-context again (assuming it was created
correctly).

To test the connman interaction, I disabled connman and setup an entry
in /etc/network/interfaces:

iface usb0 inet dhcp

I then ran "ifup usb0". I got an IP address the route and resolv.conf
were updated automatically. This time there was no inet6 addr. ping,
wget, and ssh are still behaving the same though.

This makes it clear to me that I have some research to do. I don't know
what those terms mean, and certainly don't know which APN I am using (or
should be using). I haven't specified one intentionally. Any tips on how
I can determine this?

Does the '?' imply that there is something clearly wrong with this listing?

This means there are no contexts.  For MBM they show up after you run
online-modem.

Assuming a brand new, virgin device, oFono runs context provisioning
using mobile-broadband-provider-info.  If you are lucky, the context
will be configured automagically and the list-contexts output will look
something like this:

denkenz(a)localhost ~/ofono-master $ test/list-contexts
[ /mbm_0 ]
    [ /mbm_0/context1 ]
        Username =
        Protocol = ip
        Name = Internet
        Settings = { }
        IPv6.Settings = { }
        Active = 0
        AccessPointName = wap.cingular
        Password =
        Type = internet

The settings are then persisted in /var/lib/ofono/<your sim card's imsi>

If provisioning fails, oFono creates a default, empty context.  It can
be recognized by an empty APN.  In theory activating an empty APN should
fail.

You then need to use create-internet-context to set the settings
manually.  For AT&T the WAP-only APN is wap.cingular, and the data APN
is isp.cingular I believe.

The SIM PIN credentials are separate from GPRS context credentials.
Essentially the SIM PIN locks the SIM card, so the modem cannot read
what is on it until the PIN is entered.  Once the access to the SIM card
is allowed, we can 'dial up' to the network.  Think of the APN details
as old style dial-up modem credentials.  E.g. APN is the phone number,
and the username and password are self-explanatory.

Correct, oFono persists the information in /var/lib/ofono.  You only
need to run create-internet-context if your settings are wrong.

This all sounds correct.  Btw, you can also use
test/process-context-settings to do the above.  It should even do the
DHCP / static assignment correctly.

If you are using an AT&T GoPhone SIM then likely you're limited to
WAP-only network, not a real internet connection.  The easy way to tell
is to run

test/create-internet-context "isp.cingular"

And then try to activate the context.

See above.

Also, I'm trying to look up the distinction between WAP-only and Full GPRS:

http://en.wikipedia.org/wiki/General_Packet_Radio_Service
http://en.wikipedia.org/wiki/Wireless_Application_Protocol

This suggests to me that this SIM can only do WAP and not IP, which
explains why my wget, ssh, and ping tests fail. I'm confused why I'm
then able to get a an inet and an inet6 address though, and DNS appears
to work.

So, is there a typical way to verify that WAP is at least working?

Should I update the context Protocol to "wap" instead of "ip" ?

Finally, if the Go Phone SIM is WAP-only, what do I need for a "Full
GPRS" SIM?

Thanks,

And this is why the context is not shown in ConnMan's list of available
services.  ConnMan ignores contexts with empty APNs as invalid.

Yep, looks like this pre-paid account is configured with access to the
APN with WAP based services only.

Have you pulled it out and re-inserted?  In general oFono does not have
a facility to persist the hardware ids unless the hardware exports its
serial number to udev.  I'm guessing this hardware does not.

Sorry I confused you.  While WAP does provide a replacement to IP, no
one ended up using it in the end.  Carriers run WAP services over HTTP
but with a weird compressed binary format.  Generally the only thing you
can reach from the "wap.cingular" APN is the WAP gateway IP and/or the
MMSC (for MMS, aka picture messaging) gateway IP.  The contexts are
still some form of IP.

> So, is there a typical way to verify that WAP is at least working?

ping the wap gateway, assuming you can find its IP on Google somewhere.

> Should I update the context Protocol to "wap" instead of "ip" ?

Nope, the Protocol setting is correct.  Carriers can choose to run
different services on different APNs (e.g. for billing or traffic
counting purposes).  Hence you can have an 'internet' APN, an mms-only
APN, a wap-only APN, everything and the kitchen sink APN.  Sometimes you
might even have a VPN-to-your-employer APN, etc.

The operator can set up different billing structures for each APN, e.g.
bill MMS by the number of messages, not bytes.

I don't know how AT&T structures their pre-paid plans these days.  I
believe you had to buy another package for $20 or so to add internet
capability to pre-paid SIMs.  You can also check out what T-Mobile is
doing for pre-paid data.

Alternatively just borrow an iPhone of someone nearby ;)

Per some random set of instructions I found on the intertubes:

http://www.unlockit.co.nz/unlockit/?p=587

I've updated the context:


AccessPointName=wap.cingular
Username=WAP(a)CINGULARGPRS.COM
Password=CINGULAR1

I still get an IP address via DHCP and name resolution is working, but
my ping,wget,ssh tests fail.

A colleague allowed me to bottow his AT&T phone. I used this SIM card
and he had the same APN and Username entered in the phone (assuming same
password, wasn't visible and he didn't want me to change it just in case
:-). His phone reported an "EDGE" connection and successfully, albeit
SLOWLY, displayed web pages.

So this suggests to me that the SIM can do IP and not just WAP. However,
it says EDGE (2G?), does ofono support EDGE? I am I off in the weeds now?

If name resolution is working, doesn't this suggest that you get packets
to the network?

You are using your pre-paid SIM in this phone correct?  Was it an older
feature-phone type device?  If so, then I suspect the phone is using the
WAP browser, not a regular internet connection.  That is what WAP
gateway is for, to convert regular HTML web pages into an 'optimized'
binary format on slow (think 10 years ago) networks.

Yes oFono supports 2G and yes you're in the weeds.  You just need to
find a SIM card with a proper data plan.  Unfortunately US carriers
don't really understand that it is useful to have actual data allowances
on prepaid plans ;)

It does, and the RX/TX counters do increase.

OK, I think I understand the situation now. I'm looking for a suitable
data plan. I'm considering something like this:

http://www.gprssim.com/index.php?route=product/product&path=20_42_26&product_id=97

They are expensive, but for validating hardware, they are probably less
expensive than the $25 I drop every 3 months for a Go Phone WAP SIM!

ofono-tests internet context: DNS works, ping wget and ssh do not (Connection Refused)

[Darren Hart]

[-- Attachment #1: Type: text/plain, Size: 4833 bytes --]

I have successfully used ofono-tests to  enable,online,activate,and
create-internet-context. I have an IP address and added the opendns servers. DNS
appears to be working and the route looks sane-ish.

However, ping, wget, and ssh all fail. ping just sits there, wget and ssh both
fail with Connection Refused.

Is there something obvious/common I might be running into?

I'm using ofono 1.5. The steps I took for context follow:

# ./enable-modem
Connecting modem /mbm_0...

# ./online-modem
Setting modem /mbm_0 online...

# ./activate-context

# ./create-internet-context
Found context /mbm_0/context1
