TECHSHIP IS A GLOBAL SUPPLIER OF WIRELESS COMPONENTS
SIMCom SIM7070E is a Multi-Band CAT-M/NB-IoT (NB2) module solution in a SMT format for the European market.
It has strong extension capability with rich interfaces including UART, GPIO etc.
It is designed for applications that need low latency, low throughput data communication in a variety of radio propagation conditions. It is ideally suited for M2M applications, such as metering, asset tracking, remote monitoring, E-health etc.
● With Power Save Mode(PSM) and Extended Discontinuous Reception(eDRX), SIM7070
can extend battery life to 10 years
● CAT-M, NB-IoT , GPRS triple mode
● The package of SIM7070E is compatible with SIM7000/SIM800F/SIM900

How to collect initial diagnostics data and logs for Simcom 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 host system and logs from the related Simcom module when creating a technical support ticket.
Detailed problem description and in what situations it present or can be reproduced.
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:
-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:
ls -l /dev/serial/by-id
ls -l /sys/bus/usb-serial/devices
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.
Test that you get a reply with command:

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:
Configs for Modem/PPP support:
Configs for USB network drivers:
Please relate to the Techship product specific web pages for vendor specific Linux integration guides.
