Just bought this : 4G/LTE Cellular Modem KIT with RPI Zero for 4G connection.
Plugged it in (obviously USB only)

First commands as per the ‘handbook’

richard@raspberrypi:~ $ atcom AT#USBCFG?

ERROR
richard@raspberrypi:~ $ atcom AT#USBCFG=0

ERROR

richard@raspberrypi:~ $ atcom AT

OK

Any ideas ?

Hi,

To see the result code of the error, enable the verbose error reporting with AT+CMEE=2, then try to run the AT commands you get the error. Also, could you please share the outputs of the following commands:

  • cat /etc/os-release
  • uname -a
  • lsusb
  • lsusb -t
  • usb-devices
  • dmesg | grep tty

Hi Ensar, thanks for your help. I think I’m OK now - I misread part of the instructions provided by SixFab
