Adds IPCP support, and creates a TUN interface for sending/receiving IP
packets.
|
|
Authentication support with CHAP and MD5
|
|
Implement LCP support for the PPP protocol.
|
|
Implement a generic protocol that can be shared by both the LCP and the
NCP implementation.
|
|
This patch implements the basic PPP protocol. LCP, NCP etc. are handled in
a different patch.
|
|
Comparing with general Huawei modem, EM770 is a full feature modem that
supports voicecall, phonebook, call forwarding, call barring, etc.

This interface exposes a read-write property for radio access technology
selection mode.

|
To implement PTY, TCP, Unix socket example to create GAtServer
instance.
|
|
It's the basic skeleton of GAtServer, including new/shutdown, ref/
unref, received_data/parse_buffer and set_discuss/set_debug.
GAtServer is to emulate the server side of AT conversation. It
complies with V.250 and 27.007 spec to accept AT command like
ATV1, ATE0 and extended command like AT+CLCC. Upper layer could
create customize server to expose TTY, tcp or unix socket to
client side application.

Add gatutil.c/h gat.h and move shared typedef and APIs into it.
So that they can be shared by GAtServer and GAtChat.

The call volume driver listens the speaker volume and microphone
gain from the AG. It also allow to synchronze the speaker and
microphone volume changes with the AG through AT+VGS and AT+VGM.
Volume level synchronization from HFP spec 1.5 Section 4.28.2
is performed on startup.

This driver handles phone informations about registration status, signal
strength and roaming status listening +CIEV commands. It also gets the
Network Operator name with +COPS commands.
|
|
HFP voicecall driver uses AT+CIEV indicator to notify call status
update according to Bluetooth HFP spec v1.5. This patch only adds single
call support.

Split up GPRS into two atoms: GPRS and GPRS Context. GPRS will handle
the areas of GPRS network registration, basic GPRS capability detection
and attach / detach.
GPRS Context will handle setting up / activating / deactivating the
indicidual contexts.
This will allow us to use the generic GPRS atom for most devices while
customizing the GPRS context accordingly.
|
|
Keep the name specific to GSM, other implementations will probably
require their own interfaces
|
|
This commit implements the GPRS context setup and teardown according to
doc/dataconnectionmanager-api.txt
One issue with the AT implementation of the api is that "Powered" (a
read-write property) can be set independently of "Attached" (read-only
property) and remain set when "Attached" is clear. The semantics would
be that the network doesn't have resources to let the modem attach,
but the modem waits for the resources to become available and then
attaches. On AT the modem is in this state only when executing +CGATT,
so currently the code will rerun +CGATT as soon as the previous one
returns with error, probably starving other commands. A possible
workaround would be for "Powered" to flip back to False after the modem
fails to attach once, or give up on having separate properties.
Alternatively we could re-try to attach periodically but on one modem
I've tried +CGATT fails after about 1 minute (that's the Calypso) and
on another only about 0.5s (Nokia phones with AT emulation).
When "Powered" is set and "RoamingAllowed" is clear and we manage to
attach and find that we're roaming, ofono resets "Powered".
We may want to catch the user trying to dial *99***1# which is the
backwards compatibility quirk for old modems (same way ofono parses
USSD strings).

Be more consistent with other drivers
|

|
|
Implementing all the voicecall methods. Tested with Nokia 2008 modems.
- problems in call creation are probably not reported properly
- deflect not implemented in modem, not properly tested
TODO: Clean up style issues and align with other drivers.
