Overview

Kannel is an open source WAP/SMS gateway used for sending and receiving text messages.


Usage Patterns

The usage pattern was always:

  • User sends us a message.
  • We might send them a reply after processing it.
  • We might also periodically need to be able to send the user a message.


Things Needed

The following software environment and gadgets are needed to continue with the setup:

  • Fedora 10
  • Internet connectivity to install kannel (Optional if kannel was already installed or compiled offline)
  • A WAP enabled mobile phone with SIM (GSM) (i have used Nokia 3110c)
  • A usb connector which could be used to connect the mobile phone to your computer.(I haven't tested with bluetooth)
  • Patience


Installing Kannel on Fedora

Kannel is available in official Fedora repository. 

 yum install kannel

optional packages

wvdial 

      yum install wvdial

Configuring Kannel as SMS Gateway

Kannel stores its configuration file in /etc/kannel.conf

The configuration file can be divided into three parts:

  • bearerbox configurations,
  • smsbox configurations,
  • wapbox configurations.

The WAPBOX configurations are not concentrated in this document.

To setup SMS Gateway with mobile phone as SMSCenter:

  • The bearerbox configuration MUST include smsbox-port variable with valid port.
  • The SMSC group MUST be defined in the configuration file to use a modem.
  • The modem group MUST be defined in the configuration file.
  • The smsbox group MUST be define in the configuration file.
  • One or more send-sms groups MUST be defined in the configuration file.
  • One or more SMS-Service groups shall be defined to process incoming SMS in the configuration file.(Note:Only needed if you want to process incoming text messages and send appropriate)

Bearerbox configuration

The Configuration for Kannel MUST include a group for bearerbox configuration named as ’core’.

Sample bearer box configuration: 

 # Default kannel configuration file
 #core group 'mandatory' identifies the group
 group = core
 #port for http administration
 admin-port = 13000
 #Password for http administration
 admin-password = hard2guess
 #Password to check status of kannel
 status-password = statuspass
 #Allow only localhost for now
 admin-deny-ip = "*.*.*.*"
 admin-allow-ip = "127.0.0.1"
 #For SMS gateway
 smsbox-port = 13001
 #For WAP gateway commented because we don't need this for now
 #wapbox-port = 13002
 #Allow localhost only
 box-deny-ip = "*.*.*.*"
 box-allow-ip = "127.0.0.1"
 wdp-interface-name = "*"
 #Log filename and log-level
 log-file = "/var/log/kannel/bearerbox.log"
 log-level = 1

Note: The log level can be 0-4 , use 0 or 1 when you are in testing and debugging phase or disk space is cheap.

SMS Center

To set up the SMS center at Kannel, you have to add a ’smsc’ group in the configuration file.Each group must me separated by a line.

The mobile phone is used as SMS center.Connect your wap enabled mobile to your computer in "Nokia mode" (Or what ever mode that makes your mobile phone as an usb modem)

Open up terminal and type the following command: 

 /bin/dmesg/ | tail -20


The output will be similar to, 

 [..]
 usb 5-2: new full speed USB device using uhci_hcd and address 2
 usb 5-2: configuration #1 chosen from 1 choice
 usb 5-2: New USB device found, idVendor=0421, idProduct=005e
 usb 5-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
 usb 5-2: Product: Nokia 3110c
 usb 5-2: Manufacturer: Nokia
 cdc_acm 5-2:1.1: ttyACM0: USB ACM device
 usbcore: registered new interface driver cdc_acm
 [..]

From the output it's obvious that mobile phone was detected, 

   cdc_acm 5-2:1.1: ttyACM0: USB ACM device

So the usb modem is, 

  /dev/ttyACM0

sample SMS Center group configuration: 

 #Identifies the SMS Center group
 group = smsc
 #Tells kannel that we are going to use mobile as smsc
 smsc = at
 #Sets the modem type to auto
 modemtype = auto
 #Identifies the modem
 device = /dev/ttyACM0
 #It should be your mobile number
 my-number = 9999999999
 log-level = 1

Modem Configuration

The modem configuration is one of the important part,the init-strings are used to initialize the modem and can vary from vendor to vendor.

Sample Modem configuration: 

 #It should be changed to work for your mobile
 group = modems
 id = nokia
 name = "Nokia 3110c"
 detect-string = "Nokia"
 init-string = "ATZ"
 init-string = "AT Q0 V1 E1 S0=0 &C1 &D2 +FCLASS=0"

Method to find out the init-string

  • Make sure that you have installed wvdial (yum install wvdial)
  • Make sure that you have connected you mobile phone and it got detected
  • Run the following command as root 
 wvdialconf
  • The possible init-string for modem configuration can be found in file 
 /etc/wvdial.conf

Sample wvdialconf file 

 -bash-3.2# cat /etc/wvdial.conf 
 [Dialer Defaults]
 Init2 = ATQ0 V1 E1 S0=0 &C1 &D2 +FCLASS=0
 Modem Type = USB Modem
 ; Phone = <Target Phone Number>
 ISDN = 0
 ; Username = <Your Login Name>
 Init1 = ATZ
 ; Password = <Your Password>
 Modem = /dev/ttyACM0
 Baud = 460800

Init1 and Init2 of wvdialconf file can be used as init-strings in kannel.conf.


If you have no luck with wvdial, then try the following:

  • GSM AT commands follow 3GPP specifications, so read 3GPP specifications.
  • Consult your manufacturer for support
  • Ask in kannel users mailing list
  • Google is your friend.

A brief note on Nokia Mobile phones

A lot of Nokia models do not support AT+CNMI command, which kannel uses as default to configure your modem.So you MUST supply an alternative init-string in group modems that works with your Nokia phone model.

SMSBOX configuration 

 group = smsbox
 bearerbox-host = 127.0.0.1
 sendsms-port = 13013
 #The sender number to be used in text messages
 global-sender = "+919994989838"
 log-level = 0

SEND-SMS Group configuration 

 group = sendsms-user
 #Username and Password for sending sms using HTTP interface
 username = kannel
 password = hard2guess
 concatenation = true
 #can  send a longer text message about 3 smses ( 3*160)
 max-messages = 3

Running Kannel

First start the Bearerbox using below command 

 bearerbox -v 1 /etc/kannel.conf &

 -bash-3.2# bearerbox -v 1 /etc/kannel.conf &

Sending SMS

Text messages can be sent using http interface.For example. 

 http://127.0.0.1:13013/cgi-bin/sendsms?username=kannel&password=hard2guess&to=9486987049&text=This+msg+is+sent+from+saga%27s+computer+with+kannel+please+reply+back+if+u+received+it

Replace the port, username,password,to and text with your own values to send text messages.

Closely looking at the log: 

  2009-07-03 18:10:41 [9146] [6] DEBUG: AT2[/dev/ttyACM0]: --> AT+CNMI=1,2,0,1,0^M 
  2009-07-03 18:10:41 [9146] [6] DEBUG: AT2[/dev/ttyACM0]: <-- ERROR
  2009-07-03 18:10:41 [9146] [6] ERROR: AT2[/dev/ttyACM0]: Generic error: ERROR

So,AT+CNMI=1,2,0,1,0^M is not supported by your mobile phone (most nokia phones don't)

Fix: Init-string variable should be added to modem definitions group in order to make things work.
