Software support
Connecting
Install packages:
sudo apt install libqmi-utils udhcpc
Create new file /etc/qmi-network.conf.
sudo vi /etc/qmi-network.conf
Inside type your APN settings:
APN=internet.xxx.xxx APN_USER=xxxxx APN_PASS=xxxxx
Start network and check status
sudo qmi-network /dev/cdc-wdm0 start sudo qmi-network /dev/cdc-wdm0 status ...... Status: connected
Check interface name
dmesg | grep "wwan0" .... qmi_wwan 3-1:1.4 wwp8s0u1i4: renamed from wwan0
Obtain ip address:
sudo udhcpc -q -f -n -i wwp8s0u1i4
Check interface
ifconfig wwp8s0u1i4 wwp8s0u1i4: flags=4305<UP,POINTOPOINT,RUNNING,NOARP,MULTICAST> mtu 1500 inet 10.167.84.92 netmask 255.255.255.248 destination 10.167.84.92 unspec 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 txqueuelen 1000 (UNSPEC) RX packets 47 bytes 16255 (16.2 KB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 163 bytes 16212 (16.2 KB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
Enabling serial port
By default when you connect the USB-gLINK to PC, qmi_wwan module is used. This is because the VID/PIN is not listed in drivers/usb/serial/option.c.
Login as root user
su -
Probe usbserial module
modprobe usbserial
Bind device VID/PID to usbserial
echo 2c7c 0125 > /sys/bus/usb-serial/drivers/generic/new_id
Check result
