On the modem with firmware revision ALT3100_04_05_06_10_A8_TF
(LTEUSB_02_04_05_10_53), it's observed that port probing doesn't
complete successfully when send-delay=0 is used.
During the CONNECT_3GPP_CONTEXT_STEP_LAST step,
connect_3gpp_context_step() conditionally creates and populates a
MMBearerConnectResult object into the GSimpleAsyncResult object when the
ipv4_config field of the Connect3gppContext struct is set. That assumes
the ipv4_config field is always initialized in
connect_dhcp_check_ready() during the
CONNECT_3GPP_CONTEXT_STEP_IP_CONFIG step. Instead of having such an
assumption, this patch modifies connect_3gpp to always initialize
the ipv4_config field, such that connect_3gpp_context_step() always
populates a MMBearerConnectResult object into the GSimpleAsyncResult
object.
With some modems, the lock/unlock of the SIM-ME interface with +CSIM=1/0
command is followed by #QSS unsolicited messages. With the current
implementation, this messages are mistaken for SIM swap events and so the
modem is first dropped and then re-probed.
With this patch, the plugin takes into account the SIM-ME lock state when
parsing #QSS unsolicited, so that the QSS handler can correctly
elaborate the messages that are not related to SIM swap events.
Currently, when SIM hot swap fails in either mm-iface or plugin, the
ModemManager still opens ports context and prints a message saying that
SIM hot swap is supported and that it's waiting for SIM insertion,
instead of clearly saying that SIM hot swap is not working.
This patch:
1. introduces a new property MM_IFACE_MODEM_SIM_HOT_SWAP_CONFIGURED
which is FALSE by default and set to TRUE only when
setup_sim_hot_swap_finish() succeded.
2. subordinates the completion of SIM hot swap setup (in
mm-broadband-modem) and the related messages to the the value of
MM_IFACE_MODEM_SIM_HOT_SWAP_CONFIGURED
Finally, this patch replaces the MBIM's sim_hot_swap_on private property
with the new property MM_IFACE_MODEM_SIM_HOT_SWAP_CONFIGURED, since they have the
same meaning.
Commit acf101335 ("telit: port mm-broadband-modem-telit to use GTask")
ported most of the modem_set_current_bands code to use GTask, but missed
a few g_simple_async_report_error_in_idle calls, which potentially leads
to an incorrect G_TASK cast in modem_set_current_bands_finish.
