Bug 2432

Hi Darren,

I tried it locally with 1.2 image for FRI2, and it works well in my side. You can follow the steps as:
(To do the steps, you need to install the ofono-test package.)

 - Make sure "connmand" and "ofonod" are running in the system.
 - Make sure the 3G modem device is installed. We can verify this step by the ofono's test program "list-modems".
 - Enable and online the 3G modem by running "enable-modem" and "online-modem"
 - Set the 3G connection context by running ofono's tool "create-internet-context". This includes the settings for ISP, AccessPointName, Protocol, etc.
 - Run the created 3G connection context by "activate-context". After this, the 3G network interface should be established.
 - Add DNS server address into /etc/resolv.conf, or use the default value.
 - Configure the address, netmask for the 3G network interface.
 - Verify the 3G connection by "ping www.intel.com" or other.

Thanks,
Dongxiao

I will try the commands you listed... but I don't see how these make the bug invalid. The bug was opened against connman, because as I understand it, the commands I listed should bring up the 3g connection. Regardless, please don't close a bug as invalid without giving the reported a chance to verify the proposed resolution.

Running through the commands in Comment #1 were successful up to the activate-context command which reported an error:

While I didn't expect it to work, at this point I reran the connman commands:

root@fri2:/usr/lib/connman/test# ./test-connman services            
* Wired                      { ethernet_00b3386ee31d_cable }

root@fri2:/usr/lib/connman/test# ./test-connman connect cellular_310410469131422_context1
net.connman.Error.Failed: Input/output error

Note the final Input/output error instead of the timeout.

So I see two potential issues:

1) ofono tests are not able to establish a connection
2) connman and ofono do not appear to be working together properly

What's the commit/branch are you using to test connman 3g feature?

poky: denzil
meta-intel: local fri2 branch

Note that later today I was able to acquire an IP address on the 3g modem using just ofono-tests. DNS lookup was working. wget and ssh would report "Connection Refused" and ping would just sit there. I've sent a note to the ofono list on this subject.

Yilong, could you help to have a try on this one? I have some steps posted in previous comments.

I have tried 3G network on the FRI2 according to [Comment 1] steps. it works well.
i can ping [www.sina.com] by Ethernet or 3G network.

It appears the trouble I am having here has been to do with using a WAP-only SIM and some necessary configuration. I will close this as not-a-bug. We still need to get connman-gnome to work though.

As you appear to have a functional 3G SIM. Can you check if connman-gnome lists the 3G interface and if it can bring it up successfully? If there are some specific steps that were necessary, can you please write those up so I can include them in the FRI2 BSP README?

Thanks!

Currently the 3G configuration is not functional in connman-gnome, and I think Paul will look at it since he re-wrote the connman-gnome due to API update.

Darren, could you help to close the bug? Or you need bug asigner to close it?

Chalking this one up to user error (or possibly lack of documentation regarding using 3G modems with ofono and connman).
