t230 at commands


Hi, I am doing a project abt industrial control using cellphone. The circuit should automatically make a call or sms in case of power failure, short ckt or in case of emmergency.

For this purpose, i want to interface the T230 Mobile with PC. But i dont know abt how to use the AT commands.

I want to ask, if suppose we have this info:

Sender's Msg Center Number: +923210006001
Receive's Msg Center Number: +923210006001
Sender's Phone Number: +923211234567
Receiver's Phone Number: +923217654321
Text To Send: "HELLO"

Is it the right hexadecimal PDU?

AT+CMGW=19
079129230100061011000C912923715634120000AA05C82293F904


the result is:

SMSC#+923210006001
Sender:+923217654321
TP_PID:00
TP_DCS:00
TP_DCS-popis:Uncompressed Text
class:0
Alphabet:Default

HELLO
Length:5


And How Can I send This PDU to cellphone through Hyper Terminal??

Greetings

First, you have to do this...

1. Get a data-cable for T230 (usb or serial)
2. Once yo have the data-cable, install drivers of it in your PC.
3. Configure the Hyperterminal using the Virtual serial port installed in step 2. The driver installs a serial port (COM3, for example)
4. In hyperterminal, type this

AT+CMGW=19 <ENTER>
>079129230100061011000C912923715634120000AA05C82293F904 <CTRL+Z> <ENTER>

and DONE.

Plus, an AT Command Set Manual, you must READ this....
