It is possible that SIM IMSI might change in roaming conditions for a sim.
Register for UIM refresh indication always and reprobe if ICCID or IMSI changes for QMI modem.
Overwrite the base class with a QMI implementation
to send DTMF characters during a call. Uses the continuous DTMF
QMI messages to support both CDMA and 3GPP networks.
When connecting via AT commands requiring a 3gpp profile with undefined
profile-id, the corresponding bearer 3gpp profile is later modified
adding the selected PDP context.
For this reason when a next connection is requested with the same
properties (that is no profile-id) the already existing bearers is not
selected because of the different profile-id value and a new one is
created.
This change lets the connection logic use a copy of the user-requested
bearer's 3gpp profile which can be modified for the logic needs, but it
is not stored and then does not compromise a bearer comparison in a next
connection request.
'mm_3gpp_profile_list_find_best' can return an unused profile ID, which
is later tested for being already activated in
'profile_manager_check_activated_profile_ready' with +GCACT?. Since the
profile does not exist, this check always fails, but the profile manager
still tries to deactivate it, which is unnecessary.
This change checks the return error from 'check_activated_profile' and skips
SET_PROFILE_STEP_DEACTIVATE_PROFILE step if error is
MM_CORE_ERROR_NOT_FOUND.
If any of the control ports ends up timing out 10 consecutive times,
the modem will be flagged as invalid and it will be reprobed from
scratch.
This allows us to detect modems that end up irresponsive in QMI or
MBIM while they're still exposed in e.g. the USB bus.
The QCDM/DIAG port is usually nowadays exclusively used by applications
gathering traces from the modem, so avoid port probing and grabbing
when plugins set the property MM_PLUGIN_ALLOWED_QCDM.
A new property MM_PLUGIN_REQUIRED_QCDM is created for those plugins
requiring the QCDM port for properly using a modem.
Avoid calling the MMBaseSim class method directly, and use the helper
mm_base_sim_load_sim_identifier() instead.
Also, rework a bit the logic to have a single completion method once
we know the current ICCID.
If the reported eSIM doesn't have profiles, there is no point in
trying to load properties like ICCID, IMSI or operator name/id.
If the reported SIM is a physical SIM, there is no point in trying
to load properties like EID or eSIM status.
If we created the SIM objects during the SIM slots processing, we
should not attempt to reload the settings that were already set during
the re-initialization, as that may end up clearing the initial
properties.
E.g. if the error reported by the MbimDevice is a timeout error, it
means the connection attempt is still ongoing in the device, we need
to ask it to stop.
Commit b497de325 introduced a change by which some common errors (e.g.
SIM missing) would be reported as MM_CORE_ERROR_ABORTED.
This had the undesired effect of making the MMBaseModem object not
flag as valid the modem, because the returned error wasn't
MM_CORE_ERROR_WRONG_STATE.
We now change this logic so that only ABORTED makes the modem object
not flagged as valid, and we'll do that only if the Modem interface
isn't exposed in DBus.
Fixes b497de325
