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 series module:
Sierra Wireless EM74xx, MC74xx series module:
Sierra Wireless EM73xx, MC73xx series module:
Simcom SIM7100, SIM7500 and SIM7600 series modules:
ZTE Welink ME3630 series:
Telit LE910C1 and LE910C4 series:
Telit LM940 and LM940A11:
Telit LM960 and LM960A18:
Telit LE910 V2 series:
On Huawei and Telit LN94x series modules the USB mode changing is done automatically by the modules Windows drivers based on current Windows version.
Please be aware that some USB mode configurations do not include any serial interfaces, making it impossible to revert the changes using AT commands.
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".
What Linux kernel modules and configs are commonly used for communicating with cellular modules over their USB interface?
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 are listed bellow. Many cellular modules base their Linux support on these modules and drivers. Once included in the kernel build, the USB interfaces will be detected and bound correctly out-of-the-box or after applying source code patches to the driver modules.
Configs for USB serial drivers:
Configs for Modem/PPP support:
Configs for USB network drivers:
Please relate to the Techship product specific web pages for vendor specific Linux integration guides.

How to access the serial AT command interfaces for Huawei HiSilicon chipset based modules in systems with Windows 8 and later?
Serial interfaces for cellular modules are recommended to be disabled by default by Microsoft for systems running Windows 8 and later.
The serial interfaces for AT commands etc. can however be exposed again by first using the tool in linked archive: "Huawei AT commands over MBIM interface tool for Windows 8-10 systems and usage guide" and send module the command bellow once (stored in module memory):
(instead of the default value AT^SETMODE=0)
The module will now reboot and new end-points will be visible for the module once re-appearing.
By installing the linked drivers: "Huawei Debug Driver V.126.96.36.199 for HiSilicon" the correct end point drivers can also be loaded for the cellular module when used in this mode.
You should now be able to find AT commands accepting serial interface as following:

How to collect initial diagnostics data and logs for Huawei cellular modules needed when requesting Techship technical support?
In order to troubleshoot and solve a technical problem, we ask you to please provide information about your system and logs from the related Huawei module when creating a technical support ticket.
Problem description of what exact problem is and in what precise situations present
Describe the host system:
-Hardware (system board, peripherals...)
-Operating system and detailed versions (E.g. Windows, Linux release, kernel...)
-Drivers and driver versions
Identify the precise details of cellular module found on label:
-SKU/BOM or P/N code
(For RMA returns the IMEI number is required also)
If you are running on a Linux based system, please capture the terminal logs bellow:
ls -l /dev/serial/by-id
ls -l /sys/bus/usb-serial/devices
The logs from module firmware can be acquired by accessing one of the USB enumerated serial (COM) interfaces accepting AT commands. (In Windows this is the PC UI serial interface). Send the following commands to module and capture the text output and include them when creating the the technical support ticket.
The support ticket can be created after login at: https://techship.com/technical_support/
Why is there no serial interface for AT-commands available in Microsoft Windows 8/10 and newer, while in Windows 7 all the traditional module serial interfaces are available?
Microsoft demands cellular module vendors to use the Mobile Broadband Interface Model (MBIM) interface for signaling in newer operating systems like Windows 8 and 10 rather than the previous serial based control channels with AT commands.
The serial ports are phased out and enumeration in the host system of these are dropped by many manufacturers because of Microsofts requirements.
The connections can be controlled graphically in Windows by the systems built in connection manager as well as by commands in the command prompt starting with: netsh mbn

How can we use the Huawei ME909s series modules with dual Ethernet interfaces and separate APNs in parallel?
The Huawei ME909s series modules can now support dual APN and dual ECM network interfaces starting from firmware version 11.617.06.00.00.
This gives the host systems the ability to separate the IP traffic for dedicated services or use cases.
A SIM subscription supporting separate active APN connections in parallel is also required.
Activate the second USB CDC ECM network interface with the following AT command:
The interface connections are established with the following AT commands:
AT^NDISDUP=1,1,"< APN1 >"
AT^NDISDUP=2,1,"< APN2 >"
Please observe that this feature is only supported by the Linux systems and drivers currently.
