Send SMS using Hyperterminal
Still struggling with sending SMS through hyperterminal. I intend to later
work on a PowerBASIC application. I can communicate thorugh
RS-232 that connects my Fargo Maestro 100 GSM Modem.
I can send and receive SMS'es using AT commands perfectly in text
format (AT+CMGF=1) but am experiencing problems with PDU format.
I tried all sorts of ways to issue a send (AT+CMGS) with PDU
format (AT+CMGF=0). Please help me to realize this. Here is my syntax:
AT+CMGF = 0
My CSCA (Message center number) is,
The desitnation number is:
+26663104703 (+266 is the country code for Lesotho)
Can you discover anything wrong with:
I've tried using PDU length AT+CMGS=16<CR>
> 0022000000000B916266134007F304D4F29C0E<ctrl-Z> and it still
The sent message is "Test"?. Remember test works fine in Text mode (AT+CMGF=1)
The result is always, +CMS ERROR: 304. I looked up this error code and it is
"Invalid PDU Mode Parameter"
I tried everything I know, please help?
Your PDU string is not encoded properly. When i use a decoder it displays as a SMS-COMMAND PDU, but should be a SMS-SUBMIT.
You can find a good document on this here:
If you only want to send text messages you can also consider using text mode instead of PDU mode:
i try ur msg, the result give me
not same as urs one... i get it from a functionable software
i think ur pdu convertor got problem
You can use PDUSpy, a freeware, to encode/decode your PDU.
