How to build

In root dir:

• sh build.sh

In option directory:

• sh build.sh

How to configure

• In /etc/usb_modeswitch.d/04e8:689a, ensure this line is enabled:

  NoDriverLoading=1

There should be no rule for product="6889".

• Set up wwan0 as dhcp interface. E.g. in Debian/Ubuntu, add this line to "/etc/network/interfaces":

iface wwan0 inet dhcp

How to connect

• sudo modprobe option && sudo rmmod option (to get module deps)
• sudo insmod ./option/option.ko
• Connect modem
• Run connect_lte.sh

or:

• sudo modprobe usbnet
• sudo insmod ./kalmia.ko
• sh chat.sh
• Monitor connection using: "minicom -o -D /dev/ttyUSB0" (NB! this seems to be required, else the modem stops)
• sudo ifup wwan0

How to reconnect

• sudo ifdown wwan0
• Unplug and plug modem (bug in firmware, "ATE1" does not work. Same with windows driver).
• If /var/log/messages indicate error in driver, rmmod kalmia, then insmod again.
• sh chat.sh
• sudo ifup wwan0
