-1 = no APN set, so use modem default. We'll have to fix a few
more things up for modems like hso/mbm that don't use ATDT and
require CIDs, but this gets us halfway there for other devices.
Pass the device's hardware IDs through modem creation and use them
when calculating the device's identifier. Add a bunch of testcases
for real hardware to ensure we don't break the device ID in the
future unless we really want to.
Disconnect didn't actually work for HSO since it overrode the parent
class's connect handler and thus didn't set the right state after
the connection was made. It turns out we can use the same logic
that 'mbm' does for connection and not have to override quite so
much of the parent class.
This also splits the authentication and connection parts into two
distinct stages, which wasn't the case before but was what was
intended.
First, generically handle registration polling if the device does
not support unsolicited registration. Second, using the new
creg/cgreg parsing functions from mm-modem-helpers.c, handle
CREG=2 unsolicited registration replies to capture the GSM LAC/CI
for the location information API.
Because of these changes we can simplify the registration polling
during connection as well by using the common registration parsing
code and the cached registration state.
For QCDM devices we want most of what MMSerialPort does, but not
the AT command handling stuff since the commands and responses
aren't AT commands nor are they even strings. So convert everything
that MMSerialPort does into a GByteArray, and let MMAtSerialPort
handle the conversion to strings when necessary.
Should have ignored errors when cleaning up old contexts that
may or may not exist. Rename hso_disable() to something more
appropriate since it's actually part of the enable/connect path,
not the disable path.
ZTE modems need to use udev rules to assign port type hints,
so generalize that and port all the plugins over to suggested
port types in the MMModem interface's grab_port() function.
Allow plugins to perform asynchronous port detection, and to defer port detection
until later. This moves the prober bits into MMPluginBase so that all plugins
can take adavantage of it only when needed; the probing is not done at udev time.
Furthermore, plugins like Novatel can flip the secondary ports over the AT mode
through deferred detection, by deferring the secondary ports until the main port
has been detected and AT$NWDMAT has been sent.
This commit also finishes the port of the rest of the plugins (except mbm) over
to the new port detection methods and plugin API.
Implement registration using unsolicited messages for generic GSM class (which
is disabled by default, HSO and Huawei plugins enable it).
Modify all GSM modem subclasses that used unsolicited messages to use the new
method.
* Add IpMethod property with known values ppp (default), static, DHCP.
* Rename DataDevice property to Device.
* Add GetIP4Config method. It should be implemented only when IpMethod==static.
* Update org.freedesktop.ModemManager.Modem.Gsm.Sms interface based on
Pablo Martí Gamboa's suggestions.
* Adjust MBM and HSO interfaces to take advantage of the generic Modem
interface.
Rework the MMCallbackInfo callback invocation.
Always use g_error_literal() where it makes sense.
Replace sleep() calls, with timeouts to not block the whole MM.
Instead of vague "send something, wait something" the responses are now
analyzed by (overridable) parsers. Makes all the modem implementations much
easier since each caller knows without any code whether the call succeeded
or failed.
Another thing that makes modem code simpler (and the whole thing more robust),
is the queueing of sent commands. Each queued command has a command and a
callback which is quaranteed to get called, even if sending failed.
Define and implement error reporting.
