Issue with GPRS not attached?

Hi there,

Has anyone seen this issue with oFono:
Error activating /ifx0/context1: org.ofono.Error.NotAttached: GPRS is
not attached

I am using IFX modem with specific hardware board. I have not seen this
issue before. I was using latest oFono from git (cloned sometimes on
Thursday, Feb 10, 2011). Maybe SIM card changed features? :-) 

[root(a)localhost test]# ./list-contexts
[ /ifx0 ]
    [ /ifx0/context1 ]
        Username = 
        Protocol = ip
        Name = Internet
        Settings = { }
        Active = 0
        AccessPointName = wap.cingular
        Password = 
        Type = internet
[root(a)localhost test]# 

Context has been created, and APN was added. Log file did not look
suspicious, so it should run fine. 

However, when I try 
[root(a)localhost test]# ./enable-gprs 
Connecting modem /ifx0...
[root(a)localhost test]#

- no error

But

[root(a)localhost test]# ./activate-context 
Error activating /ifx0/context1: org.ofono.Error.NotAttached: GPRS is
not attached

GPRS driver was successful loaded, and several GPRS channels created
during the ifx_enable(), from plugin. Each GPRS context seems to be
added properly. 

I have not seen any particular error in the log, that would hint
something more solid. 

Connman does not see the celular profile, as well.

Thanks for hints,
-- r.

Hi Robertino,

this normally does mean exactly what it says. You are not attached to
the GPRS network. If not attached you can not establish any GPRS
connection.

You might wanna check with list-modem if you are actually registered to
the CS network and then if so if the PS network is attached or not.

Of course that is just fine. This does not involve any network activity.
It just adds the atoms.
