New page

Gsm modem and sms sending in OpenWrt

On the stage of configuration OpenWrt the following modules are to be selected:
Kernel modules:
Video Support:

<M> kmod-usb-serial
<M> kmod-usb-serial-option
<M> kmod-usb-serial-wwan

I had a problem with the installation of the module kmod-usb-serial-wwan. mesg gave out the following after downloading:

option: Unknown symbol usb_wwan_write (err 0)
option: Unknown symbol usb_wwan_close (err 0)
option: Unknown symbol usb_wwan_release (err 0)
option: Unknown symbol usb_wwan_tiocmget (err 0)
option: Unknown symbol usb_wwan_chars_in_buffer (err 0)
option: Unknown symbol usb_wwan_write_room (err 0)
option: Unknown symbol usb_wwan_disconnect (err 0)
option: Unknown symbol usb_wwan_startup (err 0)
option: Unknown symbol usb_wwan_set_termios (err 0)
option: Unknown symbol usb_wwan_dtr_rts (err 0)
option: Unknown symbol usb_wwan_open (err 0)
option: Unknown symbol usb_wwan_tiocmset (err 0)

It can be solved by editing the file 'package/kernel/modules/usb.mk'.
Add the section 'kmod-usb-serial-wwan'

define KernelPackage/usb-serial-wwan
TITLE:=Support for GSM and CDMA modems
KCONFIG:=CONFIG_USB_SERIAL_WWAN
FILES:=$(LINUX_DIR)/drivers/usb/serial/usb_wwan.ko
AUTOLOAD:=$(call AutoLoad,61,usb_wwan)
$(call AddDepends/usb-serial)
endef

define KernelPackage/usb-serial-wwan/description
Kernel support for USB GSM and CDMA modems
endef

$(eval $(call KernelPackage,usb-serial-wwan))
Edit section 'usb-serial-option'
define KernelPackage/usb-serial-option
TITLE:=Support for Option HSDPA modems
DEPENDS:=+kmod-usb-serial-wwan
KCONFIG:=CONFIG_USB_SERIAL_OPTION

All this are described here: https://dev.openwrt.org/ticket/7731. Thanks a lot to the author.

Install:

Configuring kmod-usb-serial-option.

Connect the modem and check the output dmesg:

usbcore: registered new interface driver usbserial
USB Serial support registered for generic
usbcore: registered new interface driver usbserial_generic
usbserial: USB Serial Driver core
USB Serial support registered for GSM modem (1-port)
option 1-1.2:1.0: GSM modem (1-port) converter detected
usb 1-1.2: GSM modem (1-port) converter now attached to ttyUSB0
option 1-1.2:1.1: GSM modem (1-port) converter detected
usb 1-1.2: GSM modem (1-port) converter now attached to ttyUSB1
option 1-1.2:1.3: GSM modem (1-port) converter detected
usb 1-1.2: GSM modem (1-port) converter now attached to ttyUSB2
usbcore: registered new interface driver option
option: v0.7.2:USB Driver for GSM modems

The modem has been detected. We can start to use it. As we can see from the log 3 devices ttyUSB were created: interface for working with sd-card, interface to configure of device, interface of data communication. We need the interface of data communication, I have ttyUSB1.

It’s easy to detect what from 3 interfaces we need. Connect the modem to the computer, start the terminal on speed of 19200 and put in the command ati. The modem should respond.

OK

For sms sending we use the utility smstools. At the moment of writing of this article it isn’t included in the standard utilities of openwrt. Therefore we download the sources from:

http://smstools3.kekekasvi.com/

It should be compiled by using a cross-compiler from openwrt. For this we should add in the file smstools3/src/Makefile нужно добавить строчку:
CC=openwrt/staging_dir/toolchain-mipsel_gcc-4.3.3+cs_uClibc-0.9.30.1/bin/mipsel-openwrt-linux-gcc
It means to show the path to the cross-compiler.

Start make. In smstools3/src/ we find a demon file of sms-server smsd, which we copy to the file system in /usr/sbin. At the same time we put into the directory /etc the configuration file smsd.conf which is necessary for the start of smsd.

/etc/smsd.conf
devices = GSM1
logfile = /var/log/smstools/smsd.log
loglevel = 7
[GSM1]
device = /dev/ttyUSB1
incoming = no
# Service Center Address
smsc = 79168960220
send_delay = 10
baudrate = 19200
rtscts = no

Downloading. For the operation of smsd we need to create the following directories (we create them using mkdir):

/var/log/smstools
/var/spool/sms/checked/
/var/spool/sms/outgoing/
/var/spool/sms/incoming/

Starting sms-server:

# smsd -c /etc/smsd.conf &

Check the log and see that the modem has been initiated:

tail -f /var/log/smstools/smsd.log

We can send sms. Sms are sending automatically after the file with sms will be placed into the directory /var/spool/sms/outgoing/

Create the file send_sms.sms and place it into this directory:
send_sms.sms

To: +79161737465

Hello from OpenWrt!

Check the log and see that the server detected a new sms which wasn’t sent, begun with its sending and after sending deleted the file:

tail -f /var/log/smstools/smsd.log
