Question

How to set up a simple data connection over the MBIM interface using libmbim and driver cdc_mbim in Linux?

Solution

Most 4G/LTE cellular modules implements the USB Implementers Forums Mobile Broadband Interface Model (MBIM) Interface. This because Microsoft request cellular module vendors to include the MBIM interface for good compatibility with Windows 8, 8.1, 10 and later systems. The Windows built-in connection manager also rely on MBIM interface for control of the cellular modules.

There is a open source Linux in-kernel driver supporting MBIM interface and it is called cdc_mbim. The library libmbim can be used to communicate with the cellular devices over the interface and do necessary configurations to trigger the data connection over the cellular network.

First install the libmbim Linux library using your system package manager like apt etc. (more details about libmbim here: https://www.freedesktop.org/wiki/Software/libmbim/)

Please relate to the FAQ bellow regarding how to set the cellular module into correct USB mode for usage with MBIM mode:
How to change USB composition mode to MBIM in cellular module, used by Windows 8 and 10 systems for data connectivity?

Verify that you have the Linux in-kernel cdc_mbim driver installed for the cellular modules exposed MBIM interface endpoint over USB:
lsusb -t
Can look e.g. like this:
...
|__ Port 1: Dev 12, If 12, Class=Communications, Driver=cdc_mbim, 480M
...
|__ Port 1: Dev 12, If 13, Class=CDC Data, Driver=cdc_mbim, 480M
...

Using libmbim with the command line interface mbimcli:
List all available options for mbimcli:
mbimcli --help-all

Check version
mbimcli --version

The cellular modules mbim interface is usually named cdc-wdm* among the devices. For mbimcli this is defined by --device=/dev/cdc-wdm0 parameter. You should also use the proxy function to enable parallel commands to be sent to module even if the interface already is in use by a data connection. This is done by including --device-open-proxy or -p in every mbimcli requst to module.
Command example to query device capabilities and information (firmware & IMEI code etc.):
mbimcli --device=/dev/cdc-wdm0 --device-open-proxy --query-device-caps

The libmbim tool: mbim-network can be used to establish a simple data connection.
First create a config file containing your network operators APN details. Save it in the default location where mbim-network searches for the file: /etc/mbim-network.conf . The parameter --profile=[PATH] can be used to alter this path when executing mbim-network.

Save the APN details, (and username, password and authentication type if necessary) into the configuration file /etc/mbim-network.conf:
APN=internet
APN_USER=
APN_PASS=
APN_AUTH=
PROXY=yes

If the APN requires a username and password then it is also required to fill in the APN_AUTH protocol type with either PAP, CHAP or MSCHAPV2.

How to start a data connection after configuration file is in place:
Enter SIM PIN (if necessary for SIM card):
mbimcli -d /dev/cdc-wdm0 -p --enter-pin=1234

Start the mbim data connection with command bellow, if successful it will print "Network started successfully"
mbim-network /dev/cdc-wdm0 start

You can now execute the mbim-set-ip script (download found bellow related to this FAQ) with sufficient system privileges:
./mbim-set-ip /dev/cdc-wdm0 wwan0

This script will collect the network interface IP configurations from the cellular module over MBIM interface using mbimcli, parse them and apply them to the network interface in Linux, this because DHCP requests are generally not supported over MBIM interfaces.

Once you have started the data connection and set the details with the mbim-set-ip script you should be able to ping the data connection:
IPv4 ping: (only supported if IPv4 address was acquired from cellular module)
ping -4 -I wwan0 8.8.8.8
ping -4 -I wwan0 google.com

IPv6 ping: (only supported if IPv6 address was acquired from cellular module)
ping -6 -I wwan0 2001:4860:4860::8888
ping -6 -I wwan0 google.com

The cellular data connection can be disconnected by commands:
Stop mbim data connection:
mbim-network /dev/cdc-wdm0 stop
Set network interface down:
ip link set wwan0 down

Other useful commands:
Query device capabilities and information (firmware & IMEI code etc.):
mbimcli -d /dev/cdc-wdm0 -p --query-device-caps

Query SIM card information:
mbimcli -d /dev/cdc-wdm0 -p --query-subscriber-ready-status

Query network registration state:
mbimcli -d /dev/cdc-wdm0 -p --query-registration-state

Query connection ip information:
mbimcli -d /dev/cdc-wdm0 -p --query-ip-configuration=0

Question

How to collect initial diagnostics data and logs for Telit cellular modules needed when requesting Techship technical support?

Solution

Solution: In order to troubleshoot and solve a technical problem, we ask you to please provide information about your system and logs from the related Telit 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:
-Model
-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:
uname -a
lsusb
lsusb -t
ifconfig -a
ls -l /dev/serial/by-id
ls -l /sys/bus/usb-serial/devices
dmesg

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 generally modem devices or AT commands serial interfaces). Send the following commands to module and capture the text output and include them when creating the the technical support ticket.

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".
