Question

How-to use automated connection establishment with SIM7600E-h when using RNDIS USB mode

Solution

Both Windows and Linux systems can support RNDIS host drivers for the SIM7600 series modules, this example is done in Linux. There is a open source Linux in-kernel driver supporting rndis host USB endpoints called rndis_host.

By default the Simcom modules are delivered with QMI/RMNET interface enabled, so you will have to change the default USB mode with AT command on the Modem/AT serial ports available over USB.
lsusb
Bus 001 Device 006: ID 1e0e:9001 Qualcomm / Option

Switch from 9001 to mode 9011 for RNDIS:
AT+CUSBPIDSWITCH=9011,1,1
The module should restart automatically and re-enumerate with the new USB IDs
Check with lsusb that you have the Simcom SIM7600 module loaded, VID PID value: 1e0e 9011
lsusb
Bus 001 Device 006: ID 1e0e:9011 Qualcomm / Option

Verify with lsusb -t that the Linux in-kernel driver rndis_host or cdc-ecm drivers are loaded correctly for interface 0 and 1.
It can look e.g. like this:
lsusb -t

/: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/8p, 480M
|__ Port 4: Dev 6, If 3, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 6, If 1, Class=CDC Data, Driver=rndis_host, 480M
|__ Port 4: Dev 6, If 6, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 6, If 4, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 6, If 2, Class=Vendor Specific Class, Driver=option, 480M
|__ Port 4: Dev 6, If 0, Class=Communications, Driver=rndis_host, 480M
|__ Port 4: Dev 6, If 5, Class=Vendor Specific Class, Driver=option, 480M

If your system don't load the option serial interfaces correctly, then they can be forcefully loaded as bellow:
modprobe option
echo 1e0e 9011 > /sys/bus/usb-serial/drivers/option1/new_id
See the following Linux kernel commit for details on how to modify the option.c driver in order to auto load the driver:
USB: serial: option: add support for Simcom SIM7500/SIM7600 RNDIS mode

For the modules network connection and interface to automatically activate you should have the SIM PIN deactivated or script it so host system provides it to module at every startup.
AT+CPIN=xxxx

A APN name provided by the network carrier which is used to establish a packet data connection to the cellular network is required. If you define a empty string as its default value, will make the module try to subscribe for correct APN name from network, however this works in many cases but not always. If so it has to be configured with commands as bellow:

Check configured APN profiles:
AT+CGDCONT?
You should have minimum the following defined to have module try request details from cellular network:
AT+CGDCONT: 1,"IPV4V6",""
AT+CGDCONT=6,"IPV4V6",""
+CGDCONT Profile 1 is used for cellular network registration and profile 6 for the RNDIS network interface data connection.

Define both APN profiles according to the details you have obtained with your cellular subscription. Most often the APN details are same for both registration and data connection, define them to profile 1 and 6.
AT+CGDCONT=1,"IPV4V6","MY-SUBSCRIPTION-APN"
AT+CGDCONT=6,"IPV4V6","MY-SUBSCRIPTION-APN"

Some APN names require additional authentication also, please refer to the AT command: AT+CGAUTH in the AT commands guide on how to define it correctly. Current auth configurations can be checked with command:
AT+CGAUTH?
Most often no auth details are needed for the profiles and they should be empty, profile 1 can be cleared with command:
AT+CGAUTH=1,0
AT+CGAUTH=6,0

If you have modified the APN information, username and passwords it is needed to re-attach to the packet switched network or re-register in the cellular network to activate the new settings. It can be done e.g. with AT+CFUN=0 command followed by AT+CFUN=1 to switch module operation mode (SIM card will be re-initialized also so PIN code have to be given again if PIN check activated).

The module will now establish the data connection according to the new settings.

If everything is working correctly and connection established you can now run a dhcp client on the network interface.
dhclient -v usb0

Question

Useful Linux kernel configs to have enableb when integrating cellular modules in the Linux kernel

Solution

Most cellular modules can be supported in Linux by using som of the in-kernel drivers. The physical data interface to the host Linux system is usually done over USB which enumerates a set of different endpoints/interfaces. A set of serial interfaces for Modem/PPP, AT commands, NMEA location data and chipset debug information are almost always available in all configurations.

In addition some type of network endpoint/interface are also available and exposed. This can vary between manufacturers and chipset vendors and can also commonly be configurable by using USB configuration mode switching or through vendor specific AT commands.

Recommended kernel configurations to enable either as part of kernel or modules are listed bellow. Many cellular modules base their Linux support on these, either supported out-of-the-box or by applying source code modifications to them.

Configs for USB serial drivers:
CONFIG_USB_SERIAL
CONFIG_USB_SERIAL_GENERIC
CONFIG_USB_SERIAL_WWAN
CONFIG_USB_SERIAL_OPTION
CONFIG_USB_SERIAL_QUALCOMM
CONFIG_USB_ACM

Configs for Modem/PPP support:
CONFIG_PPP
CONFIG_PPP_BSDCOMP
CONFIG_PPP_DEFLATE
CONFIG_PPP_FILTER
CONFIG_PPP_MPPE
CONFIG_PPP_MULTILINK
CONFIG_PPPOE

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. This driver can be used together with ModemManager and NetworkManager to automate connection establishment and as a connection manager.

The library libqmi which ModemManager uses can also be used to communicate in a more direct way with the cellular devices over the QMI interface and to step by step do necessary configurations and trigger the data connection over the cellular network.

A selection of cellular modules can be supported:

Using RAW IP kernel configuration:
Sierra Wireless MC74 series, EM74 series, EM75** series
Telit LM940, LM960
Telit LN94x series (requires USB mode switch)
Simcom SIM7500 series, SIM7600 series, SIM7600 -H series
(can be supported in qmi_wwan driver from kernel 4.18 or by applying the following one line qmi_wwan source code patch on previous kernel builds: qmi_wwan: apply SET_DTR quirk to the SIMCOM shared device ID)

Using 802.3 IP framing kernel configuration:
Simcom SIM7100 series
Sierra Wireless MC73**/EM73** series

ModemManager combined with NetworkManager will detect the cellular modules automatically in most cases, please refer to their respective documentations on how to establish a data connection using them.

Example on how to set up the data connection step by step manually with libqmi:
First install the libqmi Linux library e.g. by using your system package manager like apt or preferably latest version from source on the Freedesktop pages for libqmi project: https://www.freedesktop.org/wiki/Software/libqmi/

Verify that you have the Linux in-kernel qmi_wwan driver installed and attached for the cellular modules QMI interface 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 commands only working on selected devices and not necessarily supported on the 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

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 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.

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.
