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
qmi_wwan: Added support for Telit LN940 series
qmi_wwan: Added support for Fibocom NL668 series
USB: serial: option: add support for GosunCn ME3630 RNDIS mode
USB: serial: option: add support for Simcom SIM7500/SIM7600 RNDIS mode
USB: serial: option: add Simcom SIM7500/SIM7600 (MBIM mode)
USB: serial: option: add Fibocom NL678 series
USB: serial: option: add Telit LN940 series
USB: serial: option: add Fibocom NL668 series
USB: serial: option: add GosunCn ZTE WeLink ME3630
qmi_wwan: apply SET_DTR quirk to the SIMCOM shared device ID

If you use any of the listed cellular modules, drivers and specified USB modes in the commits above, ensure that your kernel version already include the patch or apply it to your build.

Question

How can we use the Simcom SIM7000 series with ECM network interface over USB in Linux systems?

Solution

In the recent firmware releases for the Simcom SIM7000 series it is possible to take advantage of the ECM network interface type over USB in order to establish data connectivity to host system instead of using Modem/PPP protocol or QMI. This how-to FAQ shows how it can be done.

The Simcom SIM7000 series expose a set of serial and QMI/RMNET interface over USB in default configuration.
By sending command:
AT+CECMMODE=1

The USB QMI/RMNET network interface can be configured to become a ECM interface instead. If this is supported in your current firmware version the module will re-enumerate in the host system with a ECM interface.

Activate the related network interface in Linux
(check assigned interface name e.g. in dmesg output)

Run a DHCP client on the network interface:
root@linux:~# dhclient -v enx00a0c6047450
Listening on LPF/enx00a0c6047450/00:a0:c6:04:74:50

The only thing needed now is to make sure that you have defined a APN for the subscription and are registered to a cellular network.

+CGDCONT: 1,"IP","m2m.tele2.com","0.0.0.0",0,0,0,0

If APN name, IP etc. is returned with AT+CGCONTRDP, you should now be able to use the ECM network interface.

Question

How to collect initial diagnostics data and logs for Simcom SIM7000 series cellular modules, needed when requesting Techship technical support?

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 Simcom 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 mandatory)

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 the cellular module firmware can be acquired by accessing the USB enumerated serial (COM) interfaces accepting AT commands. They can be named modem, AT, PC UI etc. (In Windows device manager, found under modem or serial interfaces). Send the following AT commands bellow to module and capture the output and include them when creating the the technical support ticket.
