Some uBlox modems support multiple, simultaneously active contexts. These
contexts are either bridged to the network interface or handled
transparently by the modem acting like a router.
The problem with this approach is that ofono and ofono clients (e.g.
mmsd) expect a dedicated _local_ network interface for each context.
As such, it doesn't make sense for ofono to set up the multiple gprs
contexts.
Some u-blox devices present a USB network class device for data and some
just switch to PPP on (one of) the communication channel(s). Whether
the atmodem or ubloxmodem gprs-context driver should be used depends on
whether or not the network interface is present; check this condition
directly when deciding which driver to us.
Some Quectel models supports different features such as GNSS or
different URC strings. Add a field in the quectel data structure to be
used when adding support for said features.
The Quectel M95 modem issues a "Call ready" notification when call and
phonebook are ready, so set up a listener for that.
The only way to know when sms is ready is to issue QINITSTAT queries.
Since sms is always ready after call and phonebook, the queries are
initiated after creating call/phonebook.
This adds support for configuring a gpio in udev to control the modem
power.
To enable gpio control, specify OFONO_QUECTEL_GPIO_CHIP and
OFONO_QUECTEL_GPIO_OFFSET in the udev environment, for example:
KERNEL=="ttymxc0", ENV{OFONO_DRIVER}="quectel", \
ENV{OFONO_QUECTEL_GPIO_CHIP}="gpiochip2", \
ENV{OFONO_QUECTEL_GPIO_OFFSET}="26"
Setup GSM 07.10 multiplexing using the kernel n_gsm line discpline
driver, and use the virtual tty devices as Aux and Modem channels.
The driver supports rts/cts on the underlying serial device. This is
enabled with OFONO_QUECTED_RTSCTS udev environment, e.g.:
KERNEL=="ttymxc0", ENV{OFONO_DRIVER}="quectel", \
ENV{OFONO_QUECTEL_RTSCTS}="on"
According to the u-blox AT Commands Manual and my tests
the response prefix of AT+UUSBCONF is "+UUSBCONF:", including
a colon. The colon was missing in the code, causing next step
to parse a number to fail, since a colon is not a number.
In a recent patch vendor family was only set if the device
did not support USBCONF, but that resulted in drivers
being registered the "generic" vendor. That caused
for instance netreg to use incorrect cmer mode and fail
on TOBY-L210.
Trying to set the networking mode to "bridge" mode in the plugin is bogus
because the setting does not apply until after the device has been
reset. Instead, the current setting should be queried.
If a user wants to set the modem networking mode, the setting should be
made outside of ofono.
The gprs-context driver has already been adjusted to query the
networking mode and to set things up accordingly.
Depending on the transport used on the data connection we want either
the "atmodem" (PPP) driver or the "ubloxmodem". For the "ubloxmodem",
we want to pass the model data so this patch wrangles some parameters to
make sure that right driver and right variant data are passed.
ttyACM0 (USB interface 02) is reportedly unreliable (breaking DHCP setup)
so the recommended approach is to use ttyACM2 (USB interface 06)
exclusively.
Some aspects of a device are detectable at runtime, like the USB profile
detection that was added in a patch preceding this one. This patch
switches the driver over from creating a new "vendor id" for each
profile to just setting a flag. This is more easily extensible as we
detect other features of the modem.
The TOBY L2 series of modems presents a number of different
configurations with different throughtput characteristics. These
configurations are packaged up as USB profiles; moreover, changing the
profile actually changes the USB model ID so this is even more like
selecting a different "device" altogether. Nonetheless, all we need to
know is which profile is selected in order to set things up correctly
and this can be queried directly.
This patch adds a call to UUSBCONF for applicable modems in order to
query the USB configuration to find out which profile is active.
This patch adds a call to CGMM into the modem_enable path in order to
establish the specific device model. From this device model string, a
model-specific capabilities structure can be selected.
Many ublox modems can sit on either the USB bus or talk directly to a
UART. The udev plugin mostly takes care of figuring out what ports to
talk to and the protocol is common for all devices after that.
This patch simplifies the setup a bit:
i) There must always be an aux channel for communication with the modem
ii) The aux channel may be found behind the string Aux for USB modems
or Device for serial modems
iii) If the Modem string is set, use it; if not set, assume it's not
available.
when the voice call driver is probing, I noticed sometimes
a CME Error with the code = 4 (operation not supported)
related to AT commands "AT+CSSN=1,1" and "AT^SLCC=1".
In the current voice call implementation for Gemalto modems
the ofono_voicecall_create() is called on the gemalto_pre_sim().
The sim is not totaly readed by the module, it is not yet
online which is causing a sporadic problem at driver
intialization also when launching some outgoing/incoming calls.
This change moves the ofono_voicecall_create() to the
gemalto_post_online() to be sure that sim is well registred
and online. Several other call related atoms are also moved to
post_online state.
The plugin for Gemalto modems is enriched with all voice-related atoms,
as well as USSD.
All except the voicecall itself are from the atmodem, while the
voicecall is from gemaltomodem.
There are a large number of files in the tree that define _GNU_SOURCE
despite not actually using features hidden behind this flag. This patch
removes all these definitions in one fell swoop...
support of 'none' in mbpi:
the default method remains CHAP, but it is overridden by NONE after
parsing the entire key for the apn and detecting no username/password
The sim atom is now created with the GEMALTO vendor instead of
CINTERION. This is because GEMALTO has superceeded CINTERION and the
gemalto plugin will be updated to handle (legacy) modems from cinterion
as well as current gemalto devices.
In some case linux report 'driver' as valid yet vid and pid as NULL.
Adding NULL check to prevent seg fault.

Since the merge of udev.c into udevng.c all cleanup function must handle
both usb devices and serial devices. Add this distinction to
check_remove(), so that is doesn't try to iterate the .serial member as
if it were a .devices list.
The return value from ofono_modem_register was not being checked. If this fails
the modem object is not setup and causes a crash. This was specifically seen
when using the mbim driver without having configured with mbim support.
Now the modem object gets destroyed properly if the modem registration fails.
Add support for the SIM7100E modem. We add a new "sim7100" plugin
because there's no other AT-based modem that has support for both GPRS
and voice calls.
This atom needs to be created in post_sim so that the APN can be
written to the default profile before the modem attempts to use the
setting to connect to the network.
