Question

How to step by step set up a data connection over QMI interface using qmicli and in-kernel driver qmi_wwan in Linux?

Solution

Several cellular modules based on Qualcomm chipsets implements the Qualcomm Qualcomm MSM (QMI) Interface.
There is a open source Linux in-kernel driver supporting this interface and it is called qmi_wwan. The library libqmi can be used to communicate with the cellular devices over the interface and do necessary configurations to trigger the data connection over the cellular network.

Sierra Wireless MC74**/EM74** series: requires RAW-IP configuration.
Sierra Wireless EM75** series: requires RAW-IP configuration.
Telit LM940: requires RAW-IP configuration.
Telit LN94x series: requires RAW-IP configuration.
Simcom SIM7500/SIM7600/SIM7600*-H series: requires RAW-IP configuration (supported in qmi_wwan driver kernel 4.18+).
Simcom SIM7100 series: 802.3 IP framing supported.
Sierra Wireless MC73**/EM73** series: 802.3 IP framing supported.

First install the libqmi Linux library e.g. by using your system package manager like apt etc. (more details about libqmi here: https://www.freedesktop.org/wiki/Software/libqmi/)

Verify that you have the Linux in-kernel qmi_wwan driver installed for the cellular modules exposed QMI interface endpoint over USB:
lsusb -t
Can look e.g. like this:
...
|__ Port 1: Dev 3, If 2, Class=Vendor Specific Class, Driver=qmi_wwan, 480M
...

If the driver is not correctly loaded, please verify that the module is set to expose the correct USB endpoints configuration toward the host system and that you have followed the provided guides from the cellular module vendors, regarding how to implement the module in Linux.

Libqmi expose a command line interface that can be used to communication with the module over QMI interface.
The qmicli help will output information about all commands available:
qmicli --help-all

The cellular modules QMI control interface are usually named cdc-wdm* e.g.:
qmicli --device=/dev/cdc-wdm0

In order to allow parallel commands to be execute on the module over QMI interface, it is recommended to use the libqmi proxy function. This can be done by including the attribute -p or --device-open-proxy in every qmicli command.

If a SIM pin is required for the SIM card, use command bellow:
qmicli --device=/dev/cdc-wdm0 -p --dms-uim-verify-pin=PIN,1234

The name of the related network interface to QMI control channel can be acquired with the command:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --get-wwan-iface

The most recent Qualcomm based cellular modules only expose QMI interfaces that can support Raw-IP mode. Sierra Wireless EM/MC74 and EM75 series modules, Telit LM940 and LN940 series for example require this.
Check what IP-mode the host system is configured for:
qmicli --device=/dev/cdc-wdm0 --get-expected-data-format
Check what IP-mode the cellular module require:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --wda-get-data-format

to change qmi_wwan driver to use Raw-IP.
Disable the network interfaces exposed by the cellular module:
ip link set dev wwan0 down
Trigger the Raw-IP support:
echo Y > /sys/class/net/wwan0/qmi/raw_ip
Enable the network interfaces again:
ip link set dev wwan0 up

Now the data connection in the cellular module can be activated e.g. with a IPv4 type configuration on the specified APN:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --wds-start-network="ip-type=4,apn=data.tre.se" --client-no-release-cid

Once "Network started" is displayed, you can send a DHCP request on the network interface.
Please note that not all DHCP clients in Linux can support Raw-IP format, udhcpc however support this for IPv4 over Raw-IP.
udhcpc -q -f -n -i wwan0

Disconnect the data bearer and data connection over QMI by command bellow and providing the network handle and CID returned at connection activation:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --wds-stop-network=NETWORK_HANDLE --client-cid=CID

Additional useful commands:

Request module manufacturer:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-manufacturer

Get module model:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-model

Get firmware version:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-revision

Get module IDs (IMEI etc.):
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --dms-get-ids

Get SIM card status:
qmicli --device=/dev/cdc-wdm0 --device-open-proxy --uim-get-card-status

Recent cellular modules like Sierra Wireless EM7565 require at least libqmi V1.20. Check version with command:
qmicli --version

If the connection was successfully set up established, you now have data connectivity. A ping to a remote server using the cellular network interface can for example prove this:
ping -I wwan0 8.8.8.8

The ifconfig Linux tool can show the current details for the network interface:
ifconfig wwan0

libqmi is well integrated and supported in ModemManager tool for Linux. ModemManager again is well integrated and supported when using NetworkManager tool in Linux. Please note however that these two tools expect the cellular module interfaces to only be used by them so if you manually want to use the libqmi library or AT commands interfaces, please turn off/disable ModemManager and NetworkManager first.

The libqmi is a generic open source library for Linux systems and QMI protocol from Qualcomm, therefor there are several commands only working on selected devices and not necessarily on supported in the specific device you use, resulting in an error message.

Question

How can we integrate the Simcom SIM7500/SIM7600 Series Linux NDIS driver in Linux kernel without rebuilding it?

Solution

The Simcom SIM7500/SIM7600 series Linux NDIS network driver can be built and installed without rebuilding the complete Linux kernel your OS distribution uses. Please see steps and pre-requirements bellow and download the attached "Simcom SIM7500 and SIM7600 Series Linux Network NDIS driver installation files and guide (without kernel rebuild)" archive to get started.

Should you instead want to include the NDIS driver into your customized Linux kernel build, please relate to "SIMCom SIM7500 - SIM7600 series modules Linux NDIS driver and system integration guide V2.01" attached to the FAQ.

All commands are supposed to be executed with elevated system privileges/as root user.

Ensure that your original kernel was built with the following config options enabled, this will allow the option and usbnet driver pre-requirments to be included in kernel. (usually already included in larger distributions)
CONFIG_USB_SERIAL=y
CONFIG_USB_SERIAL_WWAN=y
CONFIG_USB_SERIAL_OPTION=y
CONFIG_USBNET=y

Build-tools and Linux header files for your kernel version are also required, these can be installed e.g. through your OS distributions package manager, on Debian/Ubuntu systems:
apt-get install build-essential make gcc
apt-get install linux-headers-`uname -r`

The in-kernel qmi_wwan driver should be blacklisted and prevented from loading as it will block the Simcom wwan driver, this is how it can be done e.g. in Ubuntu systems:
grep -q -F 'blacklist qmi_wwan' /etc/modprobe.d/blacklist-modem.conf || echo 'blacklist qmi_wwan' >> /etc/modprobe.d/blacklist-modem.conf

Build and install the driver:
Unzip the archive and copy the folder sim7600 to your selected working directory.
Navigate to it, e.g.:
cd /usr/src/sim7600/

Build and install the drivers:
make install

Some warnings might appear, but verify that no errors are reported.

Restarting the host system should now result in the correct network drivers being loaded for the cellular module once the USB device is detected in the system.

It can be verified by finding lsusb -t listing "Driver=simcom_wwan" for a USB endpoint:
lsusb
Bus 001 Device 005: ID 1e0e:9001 Qualcomm / Option

lsusb -t
/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/8p, 480M
|__ Port 4: Dev 5, If 0, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 1, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 2, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 3, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 4, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 5, If 5, Class=Vendor Specific Class, Driver=simcom_wwan, 480M

dmesg | grep 'simcom_wwan'
simcom_wwan 1-4:1.5 wwan0: register 'simcom_wwan' at usb-0000:00:15.0-4, SIMCOM wwan/QMI device, 8a:d8:ff:c2:87:11

Additional make options and information:
If you've built the driver previously already, first clean out any old builds with:
make clean

If you only want to build the driver but not install it into /lib/modules/`uname -r`/kernel/drivers/net/usb/, use make without install parameter:
make

Testing of the cellular connection can easily be done by first performing the necessary initiation AT commands to the cellular module over Modem/AT commands serial interface normally located on /dev/ttyUSB2. Use e.g. minicom tool to communicate with it.
Can be installed e.g. through the distributions package manager:
apt-get install minicom

Access the serial interface:
minicom -D /dev/ttyUSB2

Please relate to AT commands guide for full details on what commands are supported.
Issue AT and check that you get OK as reply.
AT

Enable echo on characters sent to module:
ATE1

Request general info about module:
ATI

Enter the SIM pin code (if necessary for SIM card)
AT+CPIN=****

Enter your operators APN details:
AT+CGDCONT=1,"IP","my.operator.apn"

Enter APN authentication details (if necessary) further details found in the AT commands guide.
AT+CGAUTH=CID,auth_type,”password”,”username”

Check network registration:
AT+CREG?

Activate and connect the cellular data connection to the network interface installed in Linux system:
AT$QCRMCALL=1,1

When you get the reply $QCRMCALL: 1, V4 from cellular module it means that the data connection to your network operator is fully established and you can now exit the minicom tool (CTRL+A followed by Z key and Q key and select yes to exit).

Once here you can now perform a DHCP request on the cellular network interface in the Linux system by using your favorite DHCP client in Linux e.g. dhclient or udhc e.g.:
dhclient -v wwan0
udhcpc --interface=wwan0

The cellular network interfaces are normally named starting from wwan0 but might get renamed by some Linux distributions automatically. All available network interfaces can be listed with command:
ip link show

The network interface can be tested e.g. by sending ping requests to a remote server over the selected network interface:
ping -I wwan0 8.8.8.8
PING 8.8.8.8 (8.8.8.8) from 10.163.183.209 wwan0: 56(84) bytes of data.

Question

How do we configure the Simcom SIM7100, SIM7500 and SIM7600 series cellular modules for usage in Windows 8 and 10 systems and support Windows built-in connection manager?

Solution

The Simcom modules comes default set in a USB configuration used by Linux and Windows 7 systems. If you want the module to be fully supported in Windows 8, 8.1, 10 systems and later and take advantage of the Windows integrated connection manager you have to do a one time configuration and set the module to expose Mobile Broadband Interface Model (MBIM) interface as bellow:

Start by installing the latest Simcom SIM7 series Windows drivers (instructions included in download package). They can be found on on our dedicated product web pages.

In Windows device manager you can now find a serial interface called "SimTech HS-USB AT Port 9001 (COM5)" Memorize the COM* interface number in your system.

Open a command prompt with admin rights (right click Windows icon in bottom left corner). Copy and paste the command bellow, edit port number to match the one in your system and hit enter. The command will then be sent to module overt the serial interface.
ECHO AT+CUSBPIDSWITCH=9004,1,1 >\\.\COM5

If the command is received successfully by module, a restart of the cellular module will be performed and it appears with the new USB endpoints supporting Windows 8 systems and later.

Make sure that all Simcom module end points are correctly loaded in Windows device manager, a system restart might be necessary also.

By clicking the Windows network connection symbol in the start bar or navigating to the "Cellular" topic in Windows system settings you can now activate the connection and configure APN details and enter PIN code if it is necessary for the cellular connection and subscription you have.

Question

How can we use Simcom SIM7500 and SIM7600 series in Linux with the MBIM control and data interface over USB connectivity?

Solution

The Simcom SIM7500 and SIM7600 series cellular module can expose the Mobile Broadband Interface Model (MBIM) Interface.

There is a open source Linux in-kernel driver supporting MBIM interface and it is called cdc_mbim. The library libmbim can be used to communicate with the cellular devices over the interface and do necessary configurations to trigger the data connection over the cellular network.

First install the libmbim Linux library using your system package manager like apt etc. (more details about libmbim here: https://www.freedesktop.org/wiki/Software/libmbim/)

First check with lsusb that you have the Simcom module set to expose MBIM interface, this can be verified with command lsusb and you should the vid:pid value 1e0e:9003.
lsusb
Bus 001 Device 003: ID 1e0e:9003 Qualcomm / Option

If this is not the case, you will have to change what USB end points the cellular module exposes and the vid:pid values. This can be done through AT commands sent to one of the modules serial interfaces accepting AT commands. dev/ttyUSB2 is often the correct one.
AT+CUSBPIDSWITCH=9003,1,1

Applications like Minicom or Picocom can be used to send AT commands over the serial interfaces.

Should you have no serial interfaces loaded, it is because the driver has not been loaded for the USB serial endpoints due to missing vid:pid values in the option driver, you can then use the commands bellow to temporarily load the driver for the vid:pid combination the module expose. e.g:
modprobe option
echo 1e0e 9001 > /sys/bus/usb-serial/drivers/option1/new_id

After you have changed the cellular modules USB endpoint configuration to expose MBIM interface, you can verify with lsusb -t that the Linux in-kernel cdc_mbim driver is correctly loaded for the cellular module. It can look e.g. like this:
lsusb -t
...
|__ Port 4: Dev 3, If 1, Class=Vendor Specific Class, Driver=, 480M
|__ Port 4: Dev 3, If 6, Class=CDC Data, Driver=cdc_mbim, 480M
|__ Port 4: Dev 3, If 4, Class=Vendor Specific Class, Driver=, 480M
|__ Port 4: Dev 3, If 2, Class=Vendor Specific Class, Driver=, 480M
|__ Port 4: Dev 3, If 0, Class=Vendor Specific Class, Driver=, 480M
|__ Port 4: Dev 3, If 5, Class=Communications, Driver=cdc_mbim, 480M
|__ Port 4: Dev 3, If 3, Class=Vendor Specific Class, Driver=, 480M

if you have no option drivers loaded for the serial interfaces, these can be loaded temporarily with commands:
modprobe option
echo 1e0e 9003 > /sys/bus/usb-serial/drivers/option1/new_id

Using libmbim with the command line interface mbimcli:
List all available options for mbimcli:
mbimcli --help-all

Check version
mbimcli --version

The cellular modules mbim interface is usually named cdc-wdm* among the devices. For mbimcli this is defined by --device=/dev/cdc-wdm0 parameter. You should also use the proxy function to enable parallel commands to be sent to module even if the interface already is in use by a data connection. This is done by including --device-open-proxy or -p in every mbimcli requst to module.
Command example to query device capabilities and information (firmware & IMEI code etc.):
mbimcli --device=/dev/cdc-wdm0 --device-open-proxy --query-device-caps

The libmbim tool: mbim-network can be used to establish a simple data connection.
First create a config file containing your network operators APN details. Save it in the default location where mbim-network searches for the file: /etc/mbim-network.conf .
The parameter --profile=[PATH] can be used to alter this path when executing mbim-network.

Save the APN details, (and username, password and authentication type if necessary) into the configuration file:
APN=
APN_USER=
APN_PASS=
APN_AUTH=
PROXY=yes

How to start a data connection after configuration file is in place:
Enter SIM PIN (if necessary for SIM card):
mbimcli -d /dev/cdc-wdm0 -p --enter-pin=1234

Start the mbim data connection with command bellow, if successful it will print "Network started successfully"
mbim-network /dev/cdc-wdm0 start

You can now execute the mbim-set-ip script (download found bellow related to this FAQ) with sufficient system privileges:
./mbim-set-ip /dev/cdc-wdm0 wwan0

This script will collect the network interface IP configurations from the cellular module over MBIM interface using mbimcli, parse them and apply them to the network interface in Linux, this because DHCP requests are generally not supported over MBIM interfaces.

Once you have started the data connection and set the details with the mbim-set-ip script you should be able to ping the data connection:
IPv4 ping: (only supported if IPv4 address was acquired from cellular module)

Question

How do we enable basic standalone GPS tracking with the SIMcom cellular modules that include GNSS tracking feature?

Solution

The SIM7100 series, SIM7500 series SIM7600 series and SIM7600 -H series cellular modules that include a GNSS tracker can be used to acquire current accurate location data with and active or passive GNSS antenna connected to the module.

Details of the available AT commands related to GNSS functionality are described in the AT command reference manuals under GPS section. The AT command reference manuals can be found under our product web pages under technical documentation tab.

Depending on if an GNSS antenna with or without low noise amplifier (active/passive antenna) are used, the AT+CVAUXV and AT+CVAUXS command can be used to adjust if the antenna power supply of 3 VDC should be enabled or disabled on the GNSS antenna connector.

Module configured for active GNSS antenna with 3VDC power supply enabled directly from module:
AT+CVAUXV=3050
AT+CVAUXS=1

Module configured for passive GNSS antenna and antenna voltage supply from cellular module is disabled:
AT+CVAUXS=0

A basic standalone GNSS tracking session outputting the location data on the dedicated NMEA virtual serial interface can be started with the following AT command:
AT+CGPS=1,1

Other useful commands:
(Please note that GNSS configuration parameters can only be changed when tracking is not active)

Stop ongoing GNSS tracking:
AT+CGPS=0

Clear GNSS fix related data stored in module:
AT+CGPSDEL

Set minimum accuracy threshold in meters for location fix (default value 50 meters):
AT+CGPSHOR=50

Enable autostart of GNSS tracking at module start up:
AT+CGPSAUTO=1

The latest GNSS fix can also be requested by AT command:
AT+CGPSINFO
And the output is in the form:
+CGPSINFO: [lat],[N/S],[log],[E/W],[date],[UTC time],[alt],[speed],[course]

For details on how to configure the GPS for different application and scenarios, such as using Assisted GPS, or changing output formats etc. please relate to the AT commands reference manuals for the specific SIMcom module.

Question

How to change USB composition mode to Mobile Broadband Interface (MBIM) that is used by Windows 8 and 10 systems for data connectivity and enabling support for the built-in connection manager in Windows?

Solution

This is done by sending AT commands to the Modem or AT serial interfaces that are accepting AT commands and changing the USB endpoint composition:

Sierra Wireless EM74xx, MC74xx series module:
AT!ENTERCND=”A710”
AT!USBCOMP=1,1,100D
AT!RESET

Sierra Wireless EM73xx, MC73xx series module:
AT!ENTERCND=”A710”
AT!UDUSBCOMP=8
AT!RESET

Simcom SIM7xxx series modules:
AT+CUSBPIDSWITCH=9003,1,1
AT+CRESET

ZTE Welink ME3630 series:
AT+ZSWITCH=8
AT+ZRST

Telit LM940:
AT#USBCFG=2
AT#REBOOT

Telit LE910x V2:
AT#USBCFG=3
AT#REBOOT

On Huawei modules the USB mode changing is done automatically by the Windows drivers and otherwise defaults to the modules standard endpoint interfaces.
