Huawei EM770W SIM card issues
Hello, we encountered the following problem with the EM770W: If the SIM card is plugged in after our test system is powered on, it is not recognised in ofono. Even if we restart ofonod after plugging in the SIM card. We use the 2.6.35~rc5 kernel from Meego 1.1 trunk because we encountered problems in the option driver with Kernel 2.6.33.3 (the communication got stuck from time to time). For ofono we use the latest 0.26 and for connman 0.55. Is this a bug relted to ofono or a limitation of the Huawei hardware?

Enabling/disabling the GPS part of a Huawei EM770W
Hello folks, is it possible to enable / disable the GPS part of a Huawei EM770W 3G modem through a DBUS command? It is done with the command AT^WPDGP and AT^WPEND on the modem (tested it on PCUI port). Or is it possible to send generic AT commands through DBUS?

ppp0 interface is not configured
Hello all,
we currently test the PPP dialup with a Huawei EM770W modem. We can
connect with create-context and activate context but the ppp device is
not configured. connman says that the device is not connected. We use
connman 0.55 and ofono 0.26.
What did we do wrong? The kernel is 2.6.35~pre5 from Meego 1.1 devel.

I never tested this with the EM777W modem, but with the Huawei modems I
have it works just fine.
Especially if it shows the DataConnectionManager interface since then
you have this properly setup and running.

This looks like an active Internet context. How did you activate this
one. Via ConnMan or via activate-context test script. If via the script,
then I think that ConnMan is not picking this up. I think that is a bug
in ConnMan.
What does list-services from ConnMan says? The devices and networks are
actually irrelevant.
Hello,
thanks for the fast reply.
Yes I activated the context with the ofono activate-context script. I
tested this method some time ago with connman 0.54 and ofono 0.24. There
it worked.
Here is the result of connman list-services:
[ /profile/default/cellular_262012020178698_primarycontext1 ]
AutoConnect = false
Strength = 74
Name = T-Mobile D
SetupRequired = true

Nameservers.Configuration = [ ]
Mode = gprs
Domains = [ ]
Ethernet = { }
Roaming = 0
IPv4.Configuration = { }
Type = cellular
Immutable = false
LoginRequired = false
How can I activate the the service from connman side via command line?
To get it right: each created context in ofono (and in the modem) is a
service for connman, right?
I have to provide some hardware testing scripts for my customer. They
want to do it automated.

Florian
