Question

How to collect initial diagnostics data and logs for Simcom 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.
