SMS - Trouble setting up SMSC in Kannel

Hello,

I'm having trouble setting up a SMSC. I'm trying to use the Huawei K3770 USB Modem as a SMSC to send an sms to a mobile device. I'm running Kannel 1.4.3 in Ubuntu 11.10, all in a VirtualBox. When I run the bearerbox, Kannel doesn't connect to the device (the status page always says "connecting"). The following is a section of the bearerbox log file. The bold sections are ones I would really like explained, as well as why the device is continually closing and opening:

I am very new to Kannel so any assistance would be greatly appreciated!!

Hi there!

I had a similar problem. Huawei modems are modems with integrated memory card and when you register it in Linux it takes two USB ports. One (usually ttyUSB0) for modem, and another (usually ttyUSB1) for memory card on which resides Windows drivers and dialup software. In futher, it has even /dev/ttyUSB2 which is free for use. When you configure Kannel to use modem on /dev/ttyUSB0, Kannel works well (at least it can start sofware) but when you configure Kannel to use /dev/ttyUSB1 it behaves like in your case.

That is why you have
2012-01-19 15:10:08 [4726] [6] INFO: AT2[huawei_k3770_00]: Closing device
2012-01-19 15:10:08 [4726] [6] INFO: AT2[huawei_k3770_00]: cannot detect speed
2012-01-19 15:10:08 [4726] [6] ERROR: AT2[huawei_k3770_00]: Couldn't connect (retrying in 10 seconds).

In further, be sure that in Linux you have same communication speed with modem like in Kannel configuration. I have choosen 57600 in Linux configuration of modem and in kannel.conf.

Finally, make a test and check "where is your modem connected to" using minicom or similar terminal software, here is a guide:

1) Shutdown Kannel
2) Open minicom sw and connect to modem on /dev/ttyUSB0
3) Using AT commands try to communicate with modem, type:
AT <enter>
you should get "OK"
if you don't switch to /dev/ttyUSB1 and try again.

From this test you will be sure "where is your modem"...where is "OK" there is modem and that port shoud be used in kannel.conf

And, don't bother for opening and closing device... I think (not sure...) Kannel is checking all the time for presence of modem ... something like keepalive ...

Hello! Thank you so much for the reply!

By using Minicom I found that the modem is using ttyUSB1. I'm running the bearerbox now and it seems to be ok. I think you are right about the opening and closing. I also searched a bit and apparently the "DSFLOWRPT..." is feedback from the modem.

But the SMSC Connections on the status page (in the web browser) still shows as just "connecting". Is this normal, or should it change to "connected" or "online"?

I am starting with Kannel ... and still away from web admin. Installation and configuration seems easy. First of all using URLs I tried to send SMSs and get stuck here - I have problem which I cannot resolve and move forward:
CMS ERROR: Unknown error. -> maybe Sim storage is full? I'll have a look at it. (500)

I have posted on this Forum the problem and waiting for some gurus to reply ...

I'm also trying to send an SMS but using Kannel from the GSM Modem to a mobile phone. I keep getting a "Routing failed, re-queued." and "trying to open device with not closed device!!". The modem isn't sending OKs anymore
