Using a huawei E1750 as a sms gateway

First we need to install some debian packages we need:

apt-get install build-essential libhid-dev bzip2 tcl8.5-dev

Because the huawei E1750 has a card reader integrated we need to disable this to use the modem, to do this we need to download Usb-modeswitch.

cd /usr/src
wget http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-1.1.4.tar.bz2
wget http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-data-20100826.tar.bz2
tar xvjf usb-modeswitch-1.1.4.tar.bz2
tar xvjf usb-modeswitch-data-20100826.tar.bz2
cd usb-modeswitch-1.1.4

make install

cd usb-modeswitch-data-20100826
make install
cp 40-usb_modeswitch.rules /etc/udev/rules.d/
udevadm control –reload_rules

Edit the file /etc/usb_modeswitch.conf en paste this below the other options.

# Configuration for the usb_modeswitch package, a mode switching tool for
# USB devices providing multiple states or modes
#
# This file is evaluated by the wrapper script “usb_modeswitch_dispatcher”
# in /usr/sbin
# To enable an option, set it to “1”, “yes” or “true” (case doesn’t matter)
# Everything else counts as “disable”

# Disable automatic mode switching globally (e.g. to access the original
# install storage)

DisableSwitching=0

# Enable logging (results in a extensive report file in /var/log, named
# “usb_modeswitch_”

EnableLogging=0

Lets execute usb_modeswitch to disable the card reader

usb_modeswitch -v 0x12d1 -p 0x1446 -H -s 5 -c /etc/usb_modeswitch.conf

You should get some output like this:

Mode switch succeeded. Bye.

The part where it says: “Mode switch succeeded. Bye.” is important, if it doesn’t say succeeded you’ll have to look for the right vendor and product id. You can find this by using lsusb.

I’ll assume it said succeeded and we are going to install everything we need to use gnokii, as i’m a great fan of MySQL i want to put all my data in mysql so we need a mysql server and the mysql version of gnokii.

apt-get install gnokii-smsd-mysql mysql-server-5.0 gnokii-cli

Setup the mysql database, create a database + user.

echo “create database smsd” | mysql -u root -p

echo “grant all on smsd.* to gnokii@’localhost’ identified by ‘password'” | mysql -u root -p

Import the gnokii sql file

mysql smsd < /usr/share/doc/gnokii-smsd-mysql/sms.tables.mysql.sql

Now our database is ready for use, the next thing we need to do is configure our gnokii.

edit /etc/gnokiirc

(this is what mine looks like)

# This is a sample ~/.gnokiirc file. Copy it into your
# home directory and name it .gnokiirc.
# See http://wiki.gnokii.org/index.php/Config for working examples.
#

[global]
port = /dev/ttyUSB0
model = AT-HW
initlength = default
connection = serial
use_locking = yes
serial_baudrate = 9600
handshake = hardware
smsc_timeout = 30

[xgnokii]
allow_breakage = 0

[gnokiid]
bindir = /usr/sbin/

[connect_script]
TELEPHONE = 12345678
[disconnect_script]

[logging]
debug = off
rlpdebug = off
xdebug = off

We should be able to see some data of our modem, lets see if gnokii can identify our huawei:

gnokii –identify

GNOKII Version 0.6.26
Couldn’t read /root/.gnokiirc config file.
Couldn’t read /root/.gnokiirc config file.
IMEI : 351910046446428
Manufacturer : huawei
Model : E1750
Product name : E1750
Revision : 11.126.00.00.00

If you see this everything should work fine.

Now we can test if we can send a sms manually.

echo “testing if we can send sms” | gnokii –sendsms +32477……

A couple of seconds later you should receive the sms on your phone.

Now lets start the smsd daemon.

/usr/sbin/smsd -u gnokii -p password -d smsd -m mysql -f /var/log/smsd/smsd.log &

And fill in some data in our outbox.

mysql smsd
insert into outbox(number,text,dreport) values (‘+32477……’,’testing if we can send from gnokii-smsd’,1);

You should receive a text message shortly
