Hi Denis,
thank you for the answer. If I can figure out the error,
and can solve the problem, I will let you know.
Hi Denis,
we figured out the problem:
At the end of a PPP connection, garbage was passed in to the AT command
parser on the modem chat.
This garbage contained a doublequote, which switched the AT syntax
parser into string mode.
However, because no second doublequote arrived, it stayed in this mode,
and kept returning UNSURE result.
I think this is an major issue that should be fixed in oFono.
The syntax parser has to be extended to handle such cases.
Regards,
Marko
