Question

How to use NetworkManager and ModemManager in Linux to automatically establish and maintain a cellular data connection?

Solution

Using NetworkManager and ModemManager in Linux to automatically establish and maintain the cellular data connection

In this FAQ we will show how to set up NetworkManager to automatically configure, establish and maintain the cellular data connection in your system.

NetworkManager and ModemManager are open source tool for Linux to manage several types of networks and interfaces such as ethernet, wifi, etc. It can also manage cellular WWAN interfaces through the ModemManager tool.
It is hosted by the Freedesktop.org community and driven by Aleksander Morgado and other contributors. please visit https://wiki.gnome.org/Projects/NetworkManager and https://www.freedesktop.org/wiki/Software/ModemManager/ for latest information, source code, API reference manuals, debugging tips, contribution, mailing list etc.

ModemManager is capable of communicating over several types of device control channels such as QMI/RMNET, MBIM, MODEM / AT command etc. But support for vendor proprietary or out-of-kernel drivers are limited. Such drivers are gobinet, simcom_wwan and other drivers provided by the vendors directly.

Many Linux distributions have NetworkManager and ModemManager pre-installed or they can typically easily be installed through the systems package manager.
In Ubuntu for example apt can install it for you by command:
apt install network-manager

Check with commands below that you have both tools installed in system and their versions.
NetworkManager -V
ModemManager -V

ModemManager (and NetworkManager) are continuously developed for better compatibility with the cellular devices, therefore it is recommend to use a recent version of the tools and in case of problem situations, evaluate the latest versions from source and check the mailing list archives for possible discussions on the problem experienced.

Keep in mind that NetworkManager and ModemManager projects are not directly developed or driven by the cellular device vendors and the compatibility with the device you aim to use can be limited. Some vendors contribute with code to make their devices fully compatible, while others don't. 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 but there are exceptions also.

Both NetworkManager and ModemManager have command line interfaces (nmcli and mmcli respectively) where you can interact with the management tools.

Relate to the following FAQ if you want more details for using ModemManager only to configure and control the cellular device but manually establish, maintain the connection and network interface IP address details.
How-to guide: control and set up a data connection in Linux using ModemManager as connection manager?

Have ModemManager list all the cellular device it has detected. Here we use the Alcatel IK41 series with MBIM interface in this example:
mmcli --list-modems
/org/freedesktop/ModemManager1/Modem/0 [Alcatel] Mobilebroadband

General details and status of them modem can be listed with "--modem" option.
mmcli --modem=0

Check that the cellular device is managed by NetworkManager by not having state "unmanaged" listed for it.
nmcli device status
DEVICE TYPE STATE CONNECTION
cdc-wdm0 gsm disconnected --
enp3s0 ethernet unmanaged --
lo loopback unmanaged --

Now you should create a connection profile in NetworkManager for your specific network carrier and SIM card with the "nmcli connection add" command:
For example:
nmcli connection add type gsm ifname '*' con-name '3-sweden' apn 'data.tre.se' connection.autoconnect yes gsm.pin 0000

- type is gsm for all typical cellular connections unless it is of cdma type.
- ifname is the control interface name, in this case cdc-wdm0, wildcard can be used also to have it autoselect.
- con-name is the profile name you want to give it.
- apn is provided by your network carrier and tells the modem what attach point it should use for the data connection.
- connection.autoconnect set to yes will make NetworkManager always try to auto connect and maintain this profile connection.
- gsm.pin lets you provide a pin code for the SIM card, that NetworkManager will try to use if PIN check is enabled for SIM card.

There are several additional commands and attributes available such as username and password settings for the APNs etc. Refer to the NetworkManager help and manual pages for full details on the commands.

If successful you should receive a reply similar to this one:
Connection '3-sweden' (cad6fcbf-2cb1-4796-b7e6-67b9f9635aef) successfully added.

You can check the status now by command:
nmcli device status
DEVICE TYPE STATE CONNECTION
cdc-wdm0 gsm connected 3-sweden
enp3s0 ethernet unmanaged --
lo loopback unmanaged --

Where connected should be listed as state if the connection establishment was successful.

If the connection is not successful or you want more details about the device and connection you can check commands:

You can list the current status with command:
nmcli radio
WIFI-HW WIFI WWAN-HW WWAN
enabled enabled enabled enabled

nmcli device show cdc-wdm

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

Print general mmcli help message:
mmcli --help

ModemManager normally listen, probes and detects cellular devices automatically when operating correctly but a forced scan can be triggered with command:
mmcli --scan-modems
<< successfully requested to scan devices

To list detected cellular devices use command:
mmcli --list-modems
<< /org/freedesktop/ModemManager1/Modem/0 [Sierra Wireless, Incorporated] MC7455

Here ModemManager have detected a Sierra Wireless cellular device and it has here been given the the identifier number 0 by ModemManager.

To acquire more device information and status use the --modem command and identifier value.
mmcli --modem=0

Currently the device status indicates that inserted SIM card is PIN locked, so a unlock by --pin command is necessary:
mmcli --modem=0 --sim=0 --pin=****
<< successfully sent PIN code to the SIM

Now we can change device state to enabled using command:
mmcli --modem=0 --enable
<< successfully enabled the modem

if we're check device status again we can see that device:
mmcli --modem=0

It is now time to activate the data connection with --simple-connect command.
ModemManager will tie the data bearer for our given subscription APN to the qmi_wwan network interface, typically named wwan0 (unless renamed by Linux distribution or user)
Fill in the details as below but for your modem number, subscription APN and the IP type it can work with (ipv4 / ipv6 ipv4v6)

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:

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 EM74xx, MC74xx series module:
AT!ENTERCND=”A710”
AT!USBCOMP=1,1,100D
AT!RESET
(See test command AT!USBCOMP=? for full usage description)

Sierra Wireless EM75xx series module:
AT!ENTERCND=”A710”
AT!USBCOMP=1,3,100D
AT!RESET
(See test command AT!USBCOMP=? for full usage description)

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:

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:
qmi_wwan: Add support for Fibocom NL678 series

Question

How to access the serial AT command interfaces for Huawei HiSilicon chipset based modules in systems with Windows 8 and later?

Solution

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):
AT^SETMODE=1
(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.2.0.6.1 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:
Huawei ME909s, and ME906s series:
HUAWEI Mobile Connect - PC UI Interface

Question

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?

Solution

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

Microsoft: Overview of mobile broadband

Question

How can we use the Huawei ME909s series modules with dual Ethernet interfaces and separate APNs in parallel?

Solution

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.

Usage instructions:
Activate the second USB CDC ECM network interface with the following AT command:
AT^SETETHNUM=2

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.
