ofono exits after DBUS error

Hi,

It looks like "AT+COPS?" returns an invalid character. I guess this is
passed to DBUS which causes oFono to exit.

Correct, but looks like the modem is doing something stupid.

I have no idea what it is sending out, but in theory COPS responses are 
limited to IRA characters.  \241 is clearly not.

The question is, what should the output look like?

Hi Denis,

I know the modem is buggy. But oFono could skip invalid characters,
this would be better then exiting.

Actually the output should be "Mobile Vikings" :-) (but this is
another bug in the modem). So "BASE" would be the correct output for
oFono.

Thanks,
Cedric

To me it sounds like the output should be BASE followed by the inverted 
'!' sign.  Unfortunately the modem is sending ISO-8859-1 characters 
instead of GSM like it is being told to do by the driver.  That 
particular character is not valid utf8, hence we go kaboom.

Having said that, I'm not familiar with 'BASE', does the above sound 
reasonable?

The operator's name is just "BASE", so i wouldn't see why there would
be an inverted '!' sign. In some AT logs i've also seen "BASE0" as a
response to AT+COPS?, so i'm thinking this last character is just
garbage.

What devices have you tried?  It may be the character is garbage, but it 
might also be it is not.  From the AT log the character you're getting 
is inverted exclamation point in Latin1 and it is a valid character in 
GSM character set...

Let me give you a background on the operators first. The operator i'm
using is is "Mobile Vikings", this is a virtual operator using the
network of an operator called "BASE".

I have three devices to test on:
- Huawei E1552:
  The first response to AT+COPS? to this device returns "Mobile
Vikings". After oFono changes to numeric format and back (AT+COPS=3,2
then back to AT+COPS=3,0), the device starts to return "BASEx". I've
already seen this return "BASE\241", "BASE0" or "BASEP". So the last
character seems pseudo-random.

- Huawei E352:
  For some reason this device doesn't register on the network, so i
don't know the output for AT+COPS?

- Option ICON 431:
  This always returns "Mobile Vikings" to AT+COPS?

Cedric
