If SIM-card is inserted, status is checked from EFsst
(is FDN activated) and EFadn (is ADN invalidated).
If USIM-card is inserted, status is checked from EFest
(is FDN activated).
If FD is enabled, halt SIM initialization procedure.
New property (FixedDialing) is added. If FD is enabled,
this has been signalled via DBUS.
The Infineon modem adds an optional <plmn_list> parameter after the
access technology parameter <AcT>. It is not always present, but when
present it makes the operator listing fail.
+COPS: (2,"T-Mobile D","TMO D","26201",0,0),(3,"E-Plus","E-Plus","26203",0,),(3,"Vodafone.de","Vodafone.de","26202",0,),(3,"o2 - de","o2 - de","26207",0,)
Not all networks have this parameter and maybe only the home network
has it anyway. And so far this feature seems to be Infineon specific,
but just in case, parse the parameter if present to make sure the
operator listing is available.
This patch adds support for setting up a GPRS context and then switching
it into M-RAW_IP mode. The handling of the M-RAW_IP data stream is not
yet implemented.
Add methods to subscribe indications from an arbitrary resource.
Configured resource id is treated as the default. Also added separate
commit function for resource subscriptions in order to reduce the
number of subscription messages sent to the modem.
This adds support to assign a slave chat instance to an existing chat
instance. The slave chat is now additionally bound by the lifetime of
its master chat instance.
In case the master is cloned, the slave chat instance will also be
cloned as well.
With this it is possible to suspend the master while still have an
active slave for notifications or extra commands.
The Infineon modem returns more detailed information of the SIM Toolkit
proactive sessions to the modem driver. A proactive session starts with
the status response '91 xx' (proactive command pending) and ends with a
status response response of '90 00' (normal ending of command) after
Terminal Response.
So only when receiving '90 00' result, the indication that the session
has ended should be given to the core.
When driving the Infineon modem with the builtin multiplexer there is
a small race condition with setting up the channels and sending the
first AT commands. The window here is pretty small, but it seems to be
a modem firmware issue. In case the AT command is send right away it can
happen that the modem does not process any further AT commands. In that
case the setup is stuck and enabling the modem fails.
Just adding a 10 milliseconds delay after DLC creation and before
sending the first AT commands is enough to make this work smoothly.
