In order to ease the troubleshooting of technical problems and understand your end-product or application and its usage scenario we ask you to please provide the following information when creating a technical support ticket at: techship.com/technical_support/ Please give a detailed problem description and in what precise circumstances it is present. Describe the host system: -Hardware (system board, processor architecture, other peripheral devices...) -Operating system with detailed versions (E.g. Windows version and build, Linux distribution, kernel version) -Drivers used and versions (Linux: out-of-tree vendor drivers or in-kernel drivers?) Details from the cellular module label: -Model -SKU/BOM or P/N code IMEI number For Linux systems, capture terminal logs from commands: uname -a lsusb lsusb -t ifconfig -a ls -l /dev/serial/by-id ls -l /sys/bus/usb-serial/devices dmesg The cellular module logs can be acquired by accessing one of the USB enumerated serial (COM) interfaces or physical UART serial interfaces accepting AT commands. In Windows device manager they are generally found as modem infterface or serial and ports interface types). Send AT commands to module and capture the text output: Test that you get a OK reply: AT Enable AT command echo: ATE1 Verbose error reporting: AT+CMEE=2 Module model: AT+CGMM Firmware version: AT+CGMR IMEI Code: AT+CGSN USB endpoint configuration: AT+GTUSBMODE?
