PDUSpy (A good tool to deal with GSM SMS PDU)

Posted by Daniel - 5,448 Views

PDUSpy ScreenshotPDUSpy is a tool to playing around with the PDU string mostly found in the GSM SMS. It can read SMS message from your GSM modem or cellphone. The interface is quite technical that is why it’s not so easy to understand. You can adjust most settings available in an SMS message structure with this tool.

On the first tabsheet, you may enter a PDU to analyze by your own, or you may import a PDU from the clipboard. If you click on ‘decode’ the PDU will be decoded, and the result will be displayed on the ‘Decode’ tab sheet. You must tell PDUspy if the message is inbound or outbound, and wether you have a GSM07.05-compatible PDU or a ETS-compatible PDU.

If your mobile phone is able to communicate with PDUspy (it needs to support AT+CMEE, AT+CMGF=0, AT+CPMS and AT+CMGL), you may as well read all messages from the phone, using the settings you made at the ‘automatic mode’ box. Be sure only to configure a SM memory which is supported by your phone, otherwise you may get a error message. Selecting ‘Archive (AR)’ will use the message archive on your local disk and will not access the phone.

you can go to this useful link: nobbi.com/pduspy.htm to get a complete overview on how to use it. If you need the code implementation about how to read SMS from your cellphone you can read the article here.

    I hv already used delphi smscodec for sending & rcving sms with success, however i ‘m not so satisfy yet, it seem that the char sent ( before converted to PDU) totally only 126 chars,not 160 char max , when i type more than 126 char then my application was hung, even i try to send using AT+CMGW=n, i try to solve this case by looking the smscodec self, and nothing to do.
    please give me goog solution for this case.
    Thanks N regard
