Question

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?

Solution

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:
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 SIM7100, SIM7500 and SIM7600 series modules:
AT+CUSBPIDSWITCH=9003,1,1
AT+CRESET

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

Telit LE910C1 and LE910C4 series:
AT#USBCFG=2
AT#REBOOT

Telit LM940 and LM940A11:
AT#USBCFG=2
AT#REBOOT

Telit LM960 and LM960A18:
AT#USBCFG=2
AT#REBOOT

Telit LE910 V2 series:
AT#USBCFG=3
AT#REBOOT

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.

Question

How to connect the Telit LM940A11 to a Mikrotik board using RouterOS?

Solution

It is recommended to have a generic mPCIe to USB adapter available to easily configure, firmware update and troubleshoot the module if needed. Such as the following adapter: https://techship.com/products/mpcie-to-usb-adapter-card/.

First, make sure that your MiktroTik board is compatible with the module by comparing the boards pin-out configuration with the modules (found in the hardware design guide).

If you have not used RouterOS or WinBox before, please refer to this guide from MikroTiks wiki page for first time start up: https://help.mikrotik.com/docs/display/ROS/First+Time+Configuration.

Make sure RouterOS is running at least version 6.46. In order to upgrade or downgrade, please follow these instructions: https://help.mikrotik.com/docs/display/ROS/Upgrading+and+installation.

Open the RouterOS terminal. Change the boot delay time to make sure the module is fully booted before the board tries to connect. This is done by going to:
/system routerboard settings
and changing "boot-delay" to 15 (seconds).

In order to use your module in RouterOS the network interface need to be set to ECM and USB 2.0 only mode. This is done by using AT commands. If you are unsure on how to send AT commands to your module, please follow this FAQ: https://techship.com/faq/how-can-i-send-at-commands-to-a-cellular-module/.

To change the network interface to ECM mode send the following AT command:
AT#USBCFG=3

The modem device will reset automatically and new USB composition is applied from the next boot up time, if this command is done successfully. Hence, in order to use "AT#USBCFG?" to double check that the new network interface was set, you may need to change the COM port.

To force the module to USB 2.0 mode only send the AT command found below. Please see this FAQ for further details: https://techship.com/faq/minipcie-based-cellular-modules-supporting-usb3-are-not-detected-in-the-host-system/.
AT#USBSWITCH=1

Now, connect your module to your MikroTik board.

Your module should now appear in the Interface list found under "Interfaces > LTE".

Question

How-to guide: How can we control, configure and establish a simple data connection for a cellular module in Linux systems using the open source ModemManager tool for modem control and connection management.

Solution

ModemManager is a open source tool for Linux that can be used to communicate with cellular devices for configuration, status check, connection triggering etc. It is capable of communicate over several types of device control channels such as QMI/RMNET, MBIM, MODEM / AT command etc.

It is hosted by the Freedesktop.org community and driven by Aleksander Morgado and other contributors, please visit https://www.freedesktop.org/wiki/Software/ModemManager/ for latest information, source code, API reference manuals, debugging tips, contribution, mailing list etc.

Keep in mind that ModemManager is not directly developed or driven by cellular device vendors and the compatibility cannot be guaranteed for the specific device you aim to use. Some vendors contribute with code to make their devices fully compatible, while others don't. However many cellular devices can be set to expose standardized types of USB network interface and control channel such as MBIM interface by USB-IF or the Qualcomm proprietary interface QMI that ModemManager will try to identify, and often manage to work successfully with.

Before continuing with ModemManager, a good thing to ensure is that you have common Linux driver modules available in your kernel build.
You can compare your own systems kernel config with the ones listed in the following FAQ:
Common Linux kernel modules and configs necessary for communicating with cellular modules over USB interface
Selections of these are commonly used by cellular devices and need to be available in order to have device drivers correctly loaded when devices are detected.

Start by installing ModemManager and its dependencies to your Linux system.
You can build it from source code release tarball found at freedesktop.org (install instructions included in the archive)
If you have a package manager in your Linux distribution, it can usually be installed through them also.
E.g. on Ubuntu using apt to install it and related dependencies:
apt install modemmanager libmbim-utils libqmi-utils

Keep in mind that Linux distributions sometimes rely on fairly old releases in their repositories and the development of ModemManager, libqmi and libmbim are on-going continuously. So is also the development of the cellular devices when the cellular technologies evolve. It is therefore recommended that you have a fairly recent version of ModemManager, libqmi and libmbim running in your system as well as when it comes to kernel version since the driver modules sometimes acquire patch fixes to be compatible with new chipset features etc.
Check Freedesktop.org pages for details on the latest ModemManager, NetworkManager, Libqmi and Libmbim releases.

Once you've installed ModemManager and rebooted your system, the service daemon should be running already in background.
Mmcli is the related command line interface tool which can be used to interact with ModemManager daemon through command line commands.

Check the version by command:
mmcli -V

From here we can see the IP details we've been assigned by the cellular network.
ModemManager does not assign IPv4 address details to the cellular modules network interface in Linux by itself.
When ModemManager is used in conjunction with NetworkManager and the cellular connection is managed by it, then the IPv4 address details will be collected by NetworkManager through ModemManager and automatically assigned to network interface when connection is established.
If the system does not implement NetworkManager, then the IP and routing configuration needs to be handled by user software/scripting.

Example:
Enable network interface in Linux:
ip link set wwan0 up

Set the IPv4 address acquired from bearer information above, the CIDR subnet mask can always be set to 32:
ip addr add 2.68.206.100/32 dev wwan0

Disable ARP:
ip link set dev wwan0 arp off

Set MTU value acquired from network:
ip link set dev wwan0 mtu 1500

Add a default or other type of route to the cellular network device (e.g. with a metric to set which route to prefer)
ip route add default dev wwan0 metric 200

Add the DNS servers reported by cellular network or use other public/desired ones.
DNS server addresses are handled in different ways depending on the Linux distribution and network manager used. Therefore please refer to related dist documentation for best practice to add / maintain DNS server addresses in your specific system.
sh -c "echo 'nameserver 80.251.201.177' >> /etc/resolv.conf"
sh -c "echo 'nameserver 80.251.201.178' >> /etc/resolv.conf"

We should now have a network interface passing data successfully, we can try it out by doing ping requests:
IPv4 data:
ping -4 -c 4 -I wwan0 8.8.8.8
PING 8.8.8.8 (8.8.8.8) from 2.68.206.100 wwan0: 56(84) bytes of data.

Question

What Linux kernel modules and configs are commonly used for communicating with cellular modules over their USB interface?

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 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:
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
CONFIG_PPP_ASYNC
CONFIG_PPP_SYNC_TTY

Configs for USB network drivers:
CONFIG_USB_USBNET
CONFIG_USB_NET_QMI_WWAN
CONFIG_USB_NET_CDCETHER
CONFIG_USB_NET_RNDIS_HOST
CONFIG_USB_NET_CDC_NCM
CONFIG_USB_NET_HUAWEI_CDC_NCM
CONFIG_USB_NET_CDC_MBIM

Please relate to the Techship product specific web pages for vendor specific Linux integration guides.

Below is a selection of kernel commits relating to cellular module support in Linux kernels:

Question

How can we establish data connection for cellular modules in Windows 8 and Windows 10 systems?

Solution

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".

Question

How to set up a simple data connection over Qualcomm QMI interface using libqmi and driver qmi_wwan in Linux?

Solution

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

Install the libqmi Linux library using e.g. your OS package manager like apt etc.
(Check out the official libqmi page here: https://www.freedesktop.org/wiki/Software/libqmi/)
Please be aware that libqmi is a 3rd party software not distributed by the chipset or module vendors. So full compatibility on all available commands should not be expected.
There are Qualcomm chipset standard QMI commands and in addition vendors specific custom QMI commands not supported by all manufacturers, but still available in libqmi. There are also new QMI commands not supported in older chipsets and vice versa, old QMI commands no longer supported in new chipset series.

Verify that you have the Linux in-kernel qmi_wwan driver installed and loaded for the cellular modules QMI interface endpoint over USB:
lsusb -t

Can look like this:
...
|__ Port 1: Dev 3, If 2, Class=Vendor Specific Class, Driver=qmi_wwan, 480M
...

If the driver is not loaded correctly, please verify that the cellular module is set to expose QMI RMNET network interface endpoint in its configuration. How to do so can often be found in AT commands guides, Linux implementation guides and similar from the cellular module vendors.

Libqmi library include a command line tool qmicli that can be used in a more convenient way communicate directly with the module over QMI interface for testing, scripting and troubleshooting.

The qmicli help will output information about all commands available:
qmicli --help-all

The qmi_wwan network control interfaces for modules are usually named like cdc-wdm# under /dev/ path.
Use the attribute --device or -d to specify it for qmicli in your command execution:
qmicli --device=/dev/cdc-wdm0
qmicli -d /dev/cdc-wdm0

In order to ease usage of the QMI interface and handle parallell command requests, libqmi include a proxy function to handle it correctly on the QMI interface, To use it, make sure to have the the attribute present in the qmicli command:
-p
--device-open-proxy

Example commands on how to communicate
Request module manufacturer:
qmicli -p -d /dev/cdc-wdm0 --dms-get-manufacturer

Get module model:
qmicli -p -d /dev/cdc-wdm0 --dms-get-model

Get firmware version:
qmicli -p -d /dev/cdc-wdm0 --dms-get-revision

Get module IDs (IMEI etc.):
qmicli -p -d /dev/cdc-wdm0 --dms-get-ids

Get SIM card status:
qmicli -p -d /dev/cdc-wdm0 --uim-get-card-status

The script qmi-network can be used to establish a simple data connection, it will automatically try to verify the IP framing type match them correctly between qmi_wwan driver and module (Raw-IP vs. 802.3 IP framing).

Create a config file containing your network operator APN details and if needed, the username and password.
Save it e.g. in the default location /etc/qmi-network.conf
The parameter --profile=[PATH] can be used to define the path to config when executing qmi-network.

Example config file content: APN details and enabling of proxy usage.
Add the username and password lines if it is needed for your APN:
APN=my-network-operators-apn
APN_USER=my-apn-username
APN_PASS=my-apn-password
PROXY=yes

Once the APN information is saved, you can start the network connection with the command:
qmi-network /dev/cdc-wdm0 start

The name of the related network interface in the Linux system can be acquired with the command:
qmicli -p -d /dev/cdc-wdm0 --get-wwan-iface

Once you see "Network started successfully" message, you can send a DHCP request on the network interface.
Please note that not all DHCP clients in Linux can handle Raw-IP format but udhcpc support it.
udhcpc -q -f -i wwan0

The IP information from the cellular network can also be acquired and set manually to the network interface by the user or scripting, the correct address details can be acquired from the cellular module over QMI with command:
qmicli -p -d /dev/cdc-wdm0 --wds-get-current-settings

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

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

To bring down and stop the cellular network connection, please use the stop command bellow:
qmi-network /dev/cdc-wdm0 stop

The ModemManager tool for Linux is based on libqmi. NetworkManager and ModemManager . 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 to collect initial diagnostics data and logs for Telit cellular modules needed when requesting Techship technical support?

Solution

In order to ease the troubleshooting of technical problems and understand your end-product or application and its usage scenario we ask you to please provide the following information when creating a technical support ticket at: techship.com/technical_support/

Please give a detailed problem description and in what precise circumstances it is present.

Describe the host system:
-Hardware (system board, processor architecture, other peripheral devices...)
-Operating system with detailed versions (E.g. Windows version and build, Linux distribution, kernel version)
-Drivers used and versions (Linux: out-of-tree vendor drivers or in-kernel drivers?)

Details from the cellular module label:
-Model
-SKU/BOM or P/N code
IMEI number

For Linux systems, capture terminal logs from commands:
uname -a
lsusb
lsusb -t
ifconfig -a
ls -l /dev/serial/by-id
ls -l /sys/bus/usb-serial/devices
dmesg

The cellular module logs can be acquired by accessing one of the USB enumerated serial (COM) interfaces or physical UART serial interfaces accepting AT commands. In Windows device manager they are generally found as modem infterface or serial and ports interface types).

Send AT commands to module and capture the text output:

Question

We cannot acquire an DHCP address over qmi_wwan driver when using Raspbian Linux OS?

Solution

Raspbian uses dhcpd to probe all available network interfaces found in the system, which is problematic for the qmi_wwan driver interface, if it is done before being configured properly when using cellular modules supporting only Raw-IP.

This can be avoided by setting dhcpd to deny the related cellular module network interface (most often named wwan0 by the system).
Add to the /etc/dhcpcd.conf file in Raspbian the following line (in the end):
denyinterfaces wwan0

Now, restart the system (preferably re-power it) so cellular module fully restarts also.

At next startup, the settings should be applied and you can now configure and use the qmi interface as described in some of the others faq's, found on the Techship webpage.
