Operating system name and version: Windows XP Prof SP3 , cygwin
Version of smsd: 3.1.14
Smsd installed from: package (smstools3-3.1.14.tar.gz, 2010-09-21 11:31)
Name and model of a modem / phone: Sierra Wireless AirCard 750+
Interface: PCI-PCMCIA adapter + PCMCIA

Hello,
I have a problem with configuration ( I hope ).
I have installed smstools + cygwin + air card drivers; modem is working (in Terminal it answers AT commands)

But It doesn't recive or send SMS messages.
something like no connection to gsm network is made.

This is my config file smsd.conf

# Example smsd.conf. Read the manual for a description

devices = PCIMCIA
logfile = /var/log/smsd.log
loglevel = 7
sent = /var/spool/sms/sent
report = /var/spool/sms/reports
outgoing = /var/spool/sms/outgoing
checked = /var/spool/sms/checked
failed = /var/spool/sms/failed
incoming = /var/spool/sms/incoming
receive_before_send = no

[PCIMCIA]
#Sierra Wireless 750+
report_device_details = yes # I found this on forum
check_network = 0 # I found this on forum
device = /dev/com3
incoming = yes
outgoing = yes
report = yes
baudrate = 9600
loglevel = 7

My log file looks like this, at the end I was trying to send SMS:



The SMS file looks like this:



As I can see in logfile there are 2 errors:
- Modem did not accept the pre-init string..., this has to be the point?
- Signal Strength Indicator..., but it should not affect sending or reciving of messages?

Can anyone point me to right direction where to look ?

This "PS busy" error... I found nothing in forum.

Have you tried this SIM with a handset, does it work?

I assume that the pre_init string does not cause the problem. Your modem just does not support CREG=2, and you can disable it using the modem setting loglevel_lac_ci = 8.

The error "PS busy" likely means the same as CMS 515, "Please wait, service is not available, init in progress". This sounds like your SIM does not register to the network. You have disabled check_network, why is that? Usually checking should not be disabled, as the modem cannot be used if it's not registered. You should enable it and check if the registration fails.

If there is no problem with registration, you should be able to receive messages using this SIM. However, you told that it cannot receive, which means that the problem should be in the registration. On the sending side, is this SIM a prepaid SIM? If it is, are you sure that it has credit enough?

Signal Strength Indicator 99,99 may mean that the feature is not supported by your modem, or that the modem does not have any signal. This may be caused by the broken antenna, or by the incorrect frequency.

THX for answer.

1) I have credits on this pre-paid card ;-)
2) I have checked SIM in regular phone - it works.
3) I have switched check_network because I wanted to show you full log (this was your request in most problems to turn this option to 0)

As I understand right now, I have to change my smsd.conf to:


I have changed baudrate because I have found info about globtrotters that this is best speed (not sure does it matter a lot ?)

I thought it's a hardware problem so there can be a PCI<->PCMCIA converter or MODEM.
I'll try to use this modem in my laptop, but right now I have no other PC to check Converter PCI-PCMCIA.

I'll let you know what is effect of this tests.

After changing what you pointed, taking PCI<>PCMCIA out of computer and puting it back I think I got it work...

Log looks like this right now:


There's still ERROR after ATE0+CMEE=1 ?

How can I fix this ?

Little bit strange... Perhaps the modem was in "bad condition", as the communication worked all the time, but the modem did not register. Anyways, good to know that it works now.

As the modem still says error to pre_init, disable it with pre_init = no, and add init = ATE0.

I have changes init = ATE0 and there's no ERROR any more ;-)

Modem is not new ;-)
I'll use it a few days and see if it's working fine.

THANK YOU FOR YOUR HELP AND TIME !!! ;-)

MJ
