Hi pende, I tried your code but it doesn't work. If I run it and send an sms (with "ping" ) to the device, I receive the sms and on stdout it shows:

New message received from +xxxxxxxxxxx
Message length 4
Message: ping
Sending reply: pong

But I don't receive the "pong" message on my other mobile.

In the code, I see that you replace the '+' by "00"; adding that to my phone number (above obfuscated with x-es) gives a total number of 13 digits. Is the odd number still a problem? If so, how can I resolve this?

This might be a daft question, but never worked with python before...

How do you initiate a function in the python file.

I.e. I see that the default with sender.py is listen. How do I run the sendmessage with number and text from CLI?

I modified
Code:
if __name__ == '__main__':
        listen()
to
Code:
if __name__ == '__main__':
        sendmessage("+XXXXXXXX", "Test")

to test it, but nothing gets sent... Where's the problem?

I'll release the full elisp code once I get this SMS stuff settled, can't get it to work so far.

A programmer has modified the script for me to accept commandline arguments, to send an SMS, so:
Code:
#!/usr/bin/python

import dbus
import sys

def octify(str):
    '''     
    Returns a list of octet bytes representing
    each char of the input str.               
    '''                                       

    bytes = map(ord, str)
    bitsconsumed = 0     
    referencebit = 7     
    octets = []          

    while len(bytes):
            byte = bytes.pop(0)
            byte = byte >> bitsconsumed
                                       
            try:
                    nextbyte = bytes[0]
                    bitstocopy = (nextbyte & (0xff >> referencebit)) << referencebit
                    octet = (byte | bitstocopy)

            except:
                    octet = (byte | 0x00)

            if bitsconsumed != 7:
                    octets.append(byte | bitstocopy)
                    bitsconsumed += 1
                    referencebit -= 1
            else:
                    bitsconsumed = 0
                    referencebit = 7

    return octets

def semi_octify(str):
    '''
    Expects a string containing two digits.
    Returns an octet -
    first nibble in the octect is the first
    digit and the second nibble represents
    the second digit.
    '''
    try:
            digit_1 = int(str[0])
            digit_2 = int(str[1])
            octet = (digit_2 << 4) | digit_1
    except:
            octet = (1 << 4) | digit_1

    return octet

def resetnumber(number):
        '''
        Adds trailing F to number if length is
        odd.
        '''
        length = len(number)
        if (length % 2) != 0:
            number = number + 'F'
        return number

def createPDUstring(number, msg):
    '''
    Returns a list of bytes to represent a valid PDU message
    '''
    octifiedmsg = octify(msg)
    number = resetnumber(number)
    octifiednumber = [ semi_octify(number[i:i+2]) for i in range(0, len(number), 2) ]
        
    HEADER = 1
    FIRSTOCTETOFSMSDELIVERMSG = 10
    ADDR_TYPE = 129 #unknown format
    number_length = len(number)
    msg_length = len(msg)
    pdu_message = [HEADER, FIRSTOCTETOFSMSDELIVERMSG, number_length, ADDR_TYPE]
    pdu_message.extend(octifiednumber)
    pdu_message.append(0)
    pdu_message.append(0)
    pdu_message.append(msg_length)
    pdu_message.extend(octifiedmsg)
    return pdu_message

class SMS(object):
    '''
    Sends sms messages 
    '''
    
    def __init__(self, msg, number):
        self.pdustring = createPDUstring(number, msg)
        
    def send(self):
        self.__dbus_send(self.pdustring)

    def __dbus_send(self, pdu_string):
        import dbus
        bus = dbus.SystemBus()
        smsobject = bus.get_object('com.nokia.phone.SMS', '/com/nokia/phone/SMS/ba212ae1')
        smsiface = dbus.Interface(smsobject, 'com.nokia.csd.SMS.Outgoing')
        arr = dbus.Array(pdu_string)
        msgdeliver = dbus.Array([arr]) 
        smsiface.Send(msgdeliver,'')
        
    def print_pdustring(self):
        print self.pdustring        

if __name__ == "__main__":
    if len(sys.argv) != 3:
        print "usage %s number message" % sys.argv[0]
    else:
        sms = SMS(sys.argv[2], sys.argv[1])
        sms.send()
        print "sending sms..."
However, when you use an international format with the leading plus like: "+XXX" for the number, it bombs with:
Code:
Traceback (most recent call last):
  File "./send_sms.py", line 114, in <module>
    sms = SMS(sys.argv[2], sys.argv[1])
  File "./send_sms.py", line 93, in __init__
    self.pdustring = createPDUstring(number, msg)
  File "./send_sms.py", line 72, in createPDUstring
    octifiednumber = [ semi_octify(number[i:i+2]) for i in range(0,
  len(number), 2) ]
  File "./send_sms.py", line 52, in semi_octify
    octet = (1 << 4) | digit_1
UnboundLocalError: local variable 'digit_1' referenced before assignment
When you use two leading zeros like "00XXXX..." it doesn't bomb, but the SMS is not received, therefore probably not sent.

It seems the problem is with the PDU encoding. Anyone got the above (prior) script to actually send an SMS? Where is the problem?

It seems the fault is definitely with this PDU encoding process. Isn't there a possibility to forward the text and number to internal Nokia PDU encoding and SMS sending routine, if there is such a thing? I.e. telepathy etc. Have been reading up through telepathy documents, but don't know how to send an SMS through its API.

Just thinking - is there any /dev/tty... interface inside OS to communicate with GSM engine using AT commands?
If such port exists, sending SMS should be rather straightforward.

Of course, you're my man, there's pnatd for communicating with the modem. OK, no to check how to send plain text SMSes via AT commands. Do you know how to do this?
