LTE modems (observed with Telit LE910 V1) can power on
already registered to a network. In that case, the SS_INFO
change notification will never arrive, and the gprs driver
will never be marked as attached.
To avoid this situation, read SS_INFO at probe time, and if
registered, mark the gprs driver as attached.
This was introduced by the previous patch:
drivers/qmimodem/devinfo.c: In function ‘get_ids_cb’:
drivers/qmimodem/devinfo.c:129:14: error: implicit declaration of function ‘strcmp’ [-Werror=implicit-function-declaration]
if (!str || strcmp(str, "0") == 0) {
On E3372 after a GPRS disconnection, modem AT channel (used by PPP) gets
disconnected (G_IO_HUP and G_IO_ERR are detected in received_data
in gatio.c).
After that all connection attempts fail because we are not able to send
any AT commands on modem channel (it is closed).
With this patch, when this behavior is detected, we close gprs context
driver, reopen AT channel and gprs context driver.
This plugin allows to provision gprs-context data based on MCC and MNC.
This is useful when provisioning using mbpi fails (either because you
are using a private APN or because there are multiple internet type context
for your operator in mbpi database).
Config file is STORAGEDIR/provisioning.
Config file should look like that:
[operator:MCC1,MNC1]
internet.AccessPointName=apn1
internet.Username=myUsername
internet.Password=myPassword
internet.AuthenticationMethod=pap
internet.Protocol=ipv6
[operator:MCC2,MNC2]
internet.AccessPointName=apn2
The only mandatory parameter for each operator is internet.AccessPointName.
Parameter description:
internet.AccessPointName: APN
internet.Username: Username
internet.Password: Password
internet.AuthenticationMethod: authentication method.
Possible values are:
- pap
- chap
Default is chap if unset.
internet.Protocol: protocol
Possible values are:
- ip: ipv4
- ipv6
- dual
Default is ip if not set.
All parameters are prefixed with internet to be able to extend this plugin
to other type of contexts (MMS, ...).
Command read_file_info on MC7304 always fails.
Using qmicli or AT command, I am able to read file info.
Qmicli command is:
qmicli -d /dev/cdc-wdm0 --uim-get-file-attributes=0x3f00,0x7fff,0x6fad
[(null)] Successfully got file '/dev/cdc-wdm0' attributes from the UIM:

After a check of parameters sent by qmimodem driver and qmicli,
the only difference is on parameter "Session Information".
Session type sent by qmimodem driver is 'Card on slot 1'.
Session type sent by qmicli command is 'primary-gw-provisioning'.
Changing session type in qmimodem driver fixed problem (on this modem).
Comparing with what is done by qmili command
Some modems do not support AT+CGDATA="PPP",X to enter data state.
Use AT+CGDATA=? to detect these modems and for them use ATD*99***X#
to enter data state.
drivers/rilmodem/stk.c: In function ‘ril_stk_probe’:
drivers/rilmodem/stk.c:210:18: error: ‘data’ is used uninitialized in
this function [-Werror=uninitialized]
struct cb_data *cbd = cb_data_new(stk, NULL, data);
At least firmware version 12.00.405 on the UE910-EUR otherwise
closes the AT command port whenever the PPP connection is
dropped, and we'd be left in a funny state.
sending RIL_REQUEST_REPORT_STK_SERVICE_IS_RUNNING after
stk atom is created so that modem will inititialize
sim toolkit by sending terminal profile to sim.
During gprs-context driver probe function, check kernel device driver
data format and modem low level data format.
If they are different, align kernel device driver data format on
modem low level data format.
If an error occurs during this process, continue probing without error.
This is inspired by what is done in qmicli and qmi-network (package
libqmi).
Add a way to get and set data format expected by kernel device driver.
This is inspired by what is done in qmicli (package libqmi).
It does not use QMI protocol but a sysfs exported by kernel driver.
To use this feature, kernel version must be equal or more than 4.5.
Network Control Model is a new Communication Device Class
protocol for exchanging Ethernet frames over USB.
NCM is intended to be used with high-speed network
attachments such as HSDPA and LTE data services.
Telit modems HE910 and UE910 share the same USB
vendor and device IDs (1bc7:0021) but they are
different devices.
HE910 is HSPA Class 14/6 and UE910 is Class 8/6.
Both come in voice-enabled variants.
HE910 also comes in variants with built-in GPS.
Add a new location-reporting driver for Gemalto Cinterion modems based
on telit implementation + use it in gemalto plugin. It supports
activation of GNSS engine (Request) with command AT^SGPSC. This driver
is tested on PHS8. NMEA frames are accessible on /dev/ttyUSB1.
Retry command QMI_UIM_GET_CARD_STATUS during query_passwd_state if a
temporary error status has been detected.
This happens with a MC7430 modem when query_passwd_state is called just
after PIN is entered.
Add a new function setup, based on telit, to handle Gemalto P-family
discovery. The setup looks for USB interfaces:
application=/dev/ttyUSB2
gps=/dev/ttyUSB1
modem=/dev/ttyUSB3
Actual cinterion plugin is not compliant with newer Gemalto modems.
Gemalto plugin is based on cinterion with a custom struct to handle the
interfaces Application and Modem.
CGDCONT result parsing fails if first list contains several ranges. For
example with modem Cinterion PHS8:
AT+CGDCONT=?
+CGDCONT: (1-17,101-116),"IP",,,(0),(0-4)
Solution: read first range and jump to second list instead of trying to
close the brackets.
Password state and number of retries asked to modem using
QMI_UIM_GET_CARD_STATUS command rather than remembered after initial
QMI_UIM_GET_CARD_STATUS command.
Add read_imsi feature to qmimodem sim driver.
This is based on DMS service.
On MC7430, this is mandatory to be able to use this driver for GPRS
connection because reading IMSI via EF reads fails.
SIM card can be removed while the query is in progress. There's
still a remote possibility that SIM card is removed and inserted
back while the query is pending, that would start the second query
sequence and end up invoking sim_initialize() twice. But at least
these checks reduce the probability of something like that happening.
QMI notification messages handlers are never called on MC7430 without this fix.
- Do not test transaction id before calling notification handler. On MC7430,
notification messages contain a not null transaction id (starts with 1,
increased at each message for a particular client).
- On MC7304 transaction id in notification messages is always 0.
Get current signal strength (type: 0x01), not list of other signals strength
(0x10)
Without this fix:
- I can't get a signal strength on MC7430 because list does not exist
(only one signal strength).
- On MC7304, result is wrong
Valgrind was complaining about it like this:
==18099== Conditional jump or move depends on uninitialised value(s)
==18099== at 0x4C32281: strspn
==18099== by 0x41286B: cbs_decode_text (smsutil.c:4140)
