Hi there,
I'm trying to use ofono with connman on an embedded system.
I'm using the latest connman and ofono releases.
So far I'm able to bring up ppp0 with ofono, but not with connman:
$ connmand --version
0.75
$ ofonod --version
0.50
$ killall ofonod
$ killall connmand
[unplug modem]
$ rm -Rf /var/lib/ofono/* # Avoid data persistence
$ rm -Rf /var/lib/connman/* # Avoid data persistence
$ ofonod -d -n &
[plug modem, wait a bit]
$ of-tests-enable-modem /huawei0
$ of-tests-online-modem
$ of-tests-set-roaming-allowed
$ of-tests-enable-gprs

Note:
- all the of-tests-XXX are the python scripts from ofono/tests directory
Now, here are my questions:
1) Is it the right sequence to bring up ppp0 with ofono?
2) To which extend, ofono is suppose to manage the routing table? I was
expecting to see a default route. As well, something strange to me is
that my ppp0 inet address is the same as the P-t-P one's and that the
gateway is 0.0.0.0!
What I'm used to with ppp is to have to do something this:
route add -host <ptp-addr> ppp0
route add default gw <ptp-addr>
But it seems to work as I can ping through ppp0...
3) Now, If I want to use connman to set up ppp0, which of these above
steps do I need to do? I was expecting to be able to set the APN, user &
password via connmand, but it seems that this feature has benn removed,
so I have to tell ofono about these settings.
My problem is that I cannot have a proper PPP network configuration with
connmand.
Any help would be greatly appreciated.
Chris
