How to collect initial diagnostics data and logs for Simcom SIM7000 series 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 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.

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:
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.
