penguin2716/qmi_setup

works fine with ThinkPad X220 and Gobi 3000 wwan module

Overview

This is a simple shellscript to make the internet connection with your QMI (Qualcomm MSM Interface) supported wwan device like Sierra Wireless Inc. Gobi 3000. QMI supported devices are listed in the source of Linux kernel (check drivers/net/usb/qmi_wwan.c with your device id). These devices are also listed at http://www.freedesktop.org/wiki/Software/ModemManager/SupportedDevices/ but not the all devices there.

Type following command to start, stop and restart the internet connection, and check your device status.

Tested environment

• ThinkPad X220 (4286-CTO)
• Gentoo/Linux, Linux Kernel 3.9.6
• Sierra Wireless, Inc. Gobi 3000 wireless wan module (FRU 60Y3257) I recommend to check if your wwan module works fine for your mobile broadband provider with Windows especially if you imported the device from other country. You may have to initialize your device for your region.
• NTT Docomo UIM card (Xi LTE SIM)

Requirements

• You have to prepare the kernel modules
  • qmi_wwan (CONFIG_USB_NET_QMI_WWAN)
  • qcserial (CONFIG_USB_SERIAL_QUALCOMM)
• QMI commands qmicli and qmi-network cmmand are required. Install them.
• APN settings APN settings are written to /etc/qmi-network.conf. In my environment, I put only a line.

  % cat /etc/qmi-network.conf
  APN=mopera.net

qmi_setup's Issues

(archlinux) ERROR while getting interface flags

wwp0s29u1u4: ERROR while getting interface flags: No such device error: couldn't create QmiDevice: Couldn't query file info: Error when getting information for file “/dev/cdc-wdm0”: No such file or directory your wwan device may be RFKilled?

As i've read from the archlinux wiki article you should activate the modem from windows... Which i didnt. Is there any way to acrivate it without installing windows in dual boot or something, if so what should I do?
