Installing Debian packages

root@cm-debian:~# apt-get install libpcap0.8 libuniconf4.6 libwvstreams4.6-base libwvstreams4.6-extras ppp wvdial

Loading kernel modules

Device driver modules require no user interaction and get loaded automatically. If for some reason device driver modules are not loaded automatically, please load them manually:

• USB Driver for GSM modems and Qualcomm MSM Interface (QMI) WWAN driver are required for SIMcom modules:

root@cl-som-imx7-sid:~# modprobe option
root@cl-som-imx7-sid:~# modprobe qmi_wwan

• USB Abstract Control Model driver is required for Telit HE910-D:

root@cl-som-imx7-sid:~# modprobe cdc-acm

Point-to-Point protocol (PPP) drivers must be loaded manually prior to dialing:

root@cl-som-imx7-sid:~# modprobe ppp_generic
root@cl-som-imx7-sid:~# modprobe ppp_async
root@cl-som-imx7-sid:~# modprobe ppp_synctty
root@cl-som-imx7-sid:~# modprobe bsd_comp
root@cl-som-imx7-sid:~# modprobe ppp_deflate

WvDial

WvDial is a Point-to-Point Protocol dialer that automatically detects modem, and can log into almost any Internet Service Provider without a complicated configuration. First, edit the wldial configuration file. Please use the a correct ISP APN instead of YOUR_ISP_APN stub:

root@cl-som-imx7-sid:~# cat /etc/wvdial.conf
[Dialer cellular]

# Your modem device. Usually /dev/ttyUSB0 or /dev/ttyACM0
#Modem = /dev/ttyACM0
Modem = /dev/ttyUSB3

# Port speeds that're worth testing:
# 921600
# 460800
# 115200
#  57600
Baud = 115200

# If your SIM card has a PIN, comment this line, uncomment the next one, and
# change the PIN shown to your PIN.
Init = ATZ
# Init = ATZ+CPIN="0000"

# If you know your ISP's APN, specify it instead of YOUR_ISP_APN below.
# If you don't, you may be able to find out on the 'net, or from tech
# support.
#
# There's also an APN table at https://wiki.ubuntu.com/NetworkManager/Hardware/3G .
#
# If you can't find it, you might be able to dial out without setting an APN
# (especially from a mobile phone). Just comment this line and uncomment
# the next one.
Init2 = AT+CGDCONT=1,"IP","YOUR_ISP_APN"
#Init2 = AT+CGDCONT=1,"IP"

# Most services/devices dial with *99# . A few seem to require *99***1#
Phone = *99#

# These often suffice, but your ISP might require different details. They're
# often dummy details used for all users on the ISP, frequently the ISP's
# name, but some ISP's do require you to use a real username and password.
Username = dummy
Password = dummy

The following command can be used for dialing:

root@cm-debian:~# wvdial cellular &
