Operating system name and version: Ubuntu 12.04
Version of smsd: 3.x (Latest)
Smsd installed from: from here
Name and model of a modem / phone:to be recommended
Interface: USB

We want to install SMS Server Tools 3.
What GSM Phone should we buy
for Germany.
Please make a recomendation !

Will Ubuntu 12.04 work.
Do you recommend another Linux OS (i.g. SuSe) ?

Hi,
I have installed sms server tools 3 on a CentOS server which is working very stable.
We bought cheap IP-GSM-Gateways from
http://www.mcm-control.com/epages/es122015.sf/de_DE/?ObjectPath=/Shops/es122015_mcm-control/Categories/%22GSM%20Modems%22
After some problems at initial configuration they are now working quite good. Comparing to other devices which are much more expensive we are quite confident with them.

kind regards,
astrakid

I installed Nokia E51.
After connecting ist to an usb port,
a new character device named /dev/bus/usb/002/003 is created, automatically.

However, when starting smsd, the log says:
"checking if modem is ready"
"unexpected error"
"write_to_modem:error 22 invalid argument."

At by init parameter does not work, either.


Questions:
Am I using the right device file ?
How can I test, whether the modem responds ?
How can I find out, which device file the modem uses ?

have a look at minicom. with this tool you can execute at-commands and other things.

astrakid

Hi Astrakid,

just executed lsusb.
It shows all usb devices.
(Mouse, USB Stick, Nokia Phone etc).

Thus, I am quite sure,
I am using the right character device.

The Nokia Phone asks,
whether to use PC Suite
or filetransfer mode, when connected ?

Which mode is correct ?


PS:
Anyway, thanks for the information
about minicom.

Would be nice,
if sms had some testmode.

Ralf Steffler

hi,
i am not sure, but i guess you have to use the pc-suite-mode. when using filetransfer you are only able to you the mass-storage-part of the phone i think...

regards,
astrakid

Hi Astrakid,

actually, it says: 'data transfer mode'.
SIM card not accessible.

I am using hypertermional
for testing the at commands.

Do you happen to know,
what at command sends out a sms and how this is done ?

hi,
from my logs i guess it have to be these commands:

=> the string for sending an sms seems to be somehow crypted...

Hi Astrakid,

you are using PDU mode.

I will try text mode
to send a test sms.

How does your smsd.conf look like ?

Ralf Steffler

quite simple:

Hi Astrakid,

you are not using an usb modem.

To send a SMS,
i only need to commands.

#set textmode
at+cmgf=1

#send sms
atcmgs="49171..."
>Hello World [Ctrl+Z]

However,
I cannot get smstools working.

It says:
checking if modem is ready
unexpected input
write_to_modem: error 22 invalid argument.



Best Wishes
Ralf Steffler

correct, but before i was using an usb-stick and didn't have to use any special init-strings.

Hi Astrakid,

it seems to me,
that smstools require cpms support.

However,
at+cpms=?
returns (),(),()

hi,
i had a look into former log_files when using a usb-modem.
CPMS seems to be used, but concerning logs I guess they are only necessary for incoming SMS...f

Hi Astrakid,

CPMS is used for sending, too.

Quote:

"AT+CPMS="ME","SM","MT"

The message_storage1 Parameter
The first parameter of the +CPMS AT command, message_storage1,
specifies the message storage area that will be used when reading or deleting SMS messages."

Anyway, I tried to cat some at commands to the GSM Phone
by "cat at_commands >/dev/bus/usb/002/014".

However, this did not work.

I will try to get minicom installed,
to test the usb interface.

Actually, I only need
two at commands to send the sms.

I am just about to write a little perl script,
which will do the job.

The perl script will
grap the right usb channel. too.

Ralf Steffler

hi,
I checked my old logs again and i am quite sure that after changing the parameter to "incoming = 0" changed the behaviour.
I couldn't find any further CPMS-messages in the logs later on even after a restart of smsd and sms were sent successfully.

regards,
astrakid

Hi Astrakid,

I changed incoming to "no"
However, the smsd.log stiill says:
"unexpected input"
"write_to_modem: error 22".

The usb device file might be the problem.

I just installed minicom to test that.

Ralf Steffler

ok. good luck.
maybe this link helps you further:

if you like we can get into a direct discussion via mail.

Hi Astrakid,

just got minicom installed.
I used the wrong device file.

The right device file is:/dev/ttyAC??

Smsd works, too.
No errors in smsd.log !!!!!!!!!!!!!!!!!!!

However, sendsms won't work.
(Minicom does).

??????????????????????

Best Wishes
Ralf Steffler

great, good starting point.
sendsms is not working? any error messages?
I did it always via smsd by a simple textfile which was copied to /....../outgoing - then smsd checks the file and processes it.
that worked fine for me.

regards,
astrakid

Hi Astrakid,

got it working !
Thanks a lot for your help !

PS:
Phone number must start with "49.."
