ASCII To PDU Converter (Convert ASCII to PDU and vice versa)

Posted by Daniel - 1,462 Views

external_pduconv.gifPDUCONV is a C source code package designed to convert the ISO-8859-1 ASCII string into a PDU-coded array as described in ETSI GSM 03.38 and ETSI GSM 03.40 and vice versa.

These functions was released to the public domain in 2003 by Mats Engstrom, Nerdlabs Consulting. Contains two callable function: ascii_to_pdu and pdu_to_ascii. From the names I guess you know what each function does.

If you would like the Delphi version of SMS-PDU encoder/decoder, you may consider the SMSCODEC - my own version of SMS processor packed as a Delphi component.

Know nothing about Delphi or C, but comfortable with Visual Basic? You can try the Visual Basic version of PDU Converter module.

    Using your “PDUASCII CODEC DEMO” to convert How are you?, I got hexa C8F71D14969741F977FD0700 but using http://twit88.com/home/utility/sms-pdu-encode-decode , I have got C8F71D14969741F977FD07 also when I manually covert the answer is C8F71D14969741F977FD07

    Hi Asari, if you enter “..C8F71D14969741F977FD0700″ or “..C8F71D14969741F977FD07000000″ in the Hexadecimal PDU Message Textarea on twit88.com, you will get the same result. I have been using the PDU generated by PDUASCII CODEC to send sms and it’s working fine, but thanks for the info, it maybe not affecting the sms-send but may affecting the other process, will check this out…

    Hi Daniel,

    was wondering if you have any code for decoding EMS… the one from twit88.com doesn’t decode correctly when receiving EMS…

    thanks

    @Lambert: No, I don’t have the code to handle EMS, but I think hesicong has what you need. You can check his work on one of his CodeProject.Com article titled: Using VB.NET to Encode SMS and EMS. It’s a good one…
