How-to change the cellular modulesUSB composition mode to Mobile Broadband Interface Model (MBIM) used by Windows 8 and 10 systems for controlling and establishing data connectivity through the built-in connection manager in Windows?
This is done by sending a set of AT commands to the cellular modules Modem or AT serial interface found in Windows Device Manager. Please see list below for associated AT commands.
(For additional details, refer to the product specific software, ports, and AT commands guides found on the Techship product web pages under technical documentation tab).
After the AT commands have been received by the module and has restarted, the USB interface endpoint composition should have changed to include MBIM interface as well.
You can find the correct Serial COM port number by checking Windows Device Manager, under the Modems drop down -> (right click and see properties for selected COM port info) or under the Ports (COM & LPT) drop down.
Vendor specific commands to use:
Sierra Wireless EM75xx, EM74xx, MC74xx series module:
Sierra Wireless EM73xx, MC73xx series module:
Simcom SIM7100, SIM7500 and SIM7600 series modules:

How can we establish data connection for cellular modules in Windows 8 and Windows 10 systems?
Microsoft Windows desktop versions starting from Windows 8 and newer have built in data connection manager for WWAN, Wifi etc. that can be used to configure, control and establish the data connection of cellular module that support MBIM interface, which most cellular modules do.
The connection managers settings and controls can be found and accessed on Windows desktop start menu through the network icon (see picture).
The Cellular tab can be found in Windows system settings and if needed the connection APN details can be manually entered through "Advanced options".
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?
The Simcom modules are by default set in a USB configuration used most often by Linux and Windows 7 systems. If you want to use the module in Windows 8, 8.1, 10 systems with the Windows integrated connection manager you have to once configure and set the module to expose Mobile Broadband Interface Model (MBIM) interface as bellow:
Start by installing the latest Simcom 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 e.g."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=9003,1,1 >\\.\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.
How to step by step set up a data connection over QMI interface using qmicli and in-kernel driver qmi_wwan in Linux?
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:
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:
The cellular modules QMI control interface are usually named cdc-wdm* e.g.:
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:
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 18.104.22.168
The ifconfig Linux tool can show the current details for the network interface:
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.
