Read the SIM (First set the phone  to store sms in sim) If delete 1-st place in sim for SMS after reading,you will find new  sms there.

hi,
1. ATE0 CR LF - turn off echo from the mobile device
2. AT+CPMS="SM","SM","SM" CR LF - set preffered message storage for mobile device (sim card in our case)
3. AT+CMGF=0 CR LF - trun sms PDU format on
4. AT+CNMI=1,1,0,0,1 CR LF- indicates new incoming sms. when, new sms arrived mobile device generate message like this: +CMTI: <mem>,<index>. where indexis the index of the incoming sms in the sotrage <mem>. in our case mem is SIM card(see command 2). you can catch this this if you enable RX interrupt in MCU.
after you got  +CMTI: <mem>,<index> you can easy read the incoming sms with command:
AT+CMGR=<index>CR LF.
you will got answer:
+CMGR: bla bla CR LF
<pdu>
where <pdu> is the sms text in PDU mode.
decode it and do anything you want.
hope this helps.
p.s. CR = 0x0D LF=0x0A

You need to study the AT commands required for the phone to function properly.

you may also wish to visit www.etsi.org for some GSM standards, like PDU and at-commands.

Hello. Anyone has made something for PDU to Normal mode for SMS?

Thanks

Hi,

you need to connect to mobile phone via RS232. When it works you can send/receive AT commands to phone. A good way to test them using PC and a terminal program. When it works you can implement into MCU.
Concerning PDU I suggest you to use normal SMS mode (if your phone can accept) The PDU is a hard game :-(

Some important common AT  commands  :
AT+CMGF=1                    -->turn on Text mode
AT+CMGL="REC UNREAD"   --> Read new messages
AT+CMGS=Tel No   +  message --> Send message       
AT+CMGD= message text  -->Delete message

After all succeeded commands Pic will wait 'OK' sign.

If you want to detect every incoming sms, use AT+CNMI command.
You will get the index from +CMTI as respond and write AT+CMGR = <index> to get the all data message.
From the message you can check the sender phone number, message etc.

Hope it helps you

any conveter for pdu to text and show on lcd?

[microcom-ecuador]

Is most easy work with text mode direct

If we say CMGF = 1 ( i see above) on the nokia phone then it will accept AT Commands ? instead of the PDU ?
