This tool is very useful for conversion of a text into a PDU, ready for sending an SMS through a 3g modem.

Before all, I want to thank Swen-Peter Ekkebus and Andrew Alexander for the initial work they published on this web site.

I've cleaned and refactored the code, to be able to work into a nodejs application. I'll work on bug fixes and improvements in future releases.

You should be able to run node test.js and view a working example.

npm install sms-pdu-node

var pdu = require('sms-pdu-node');

console.log(pdu('ciao', '393420011223')); // defaults to 8 bit

console.log(pdu('ciao', '393420011223', null. 7)); // 7 bit!

screen /dev/ttyUSB0 9600
AT+CMGS=XX   # XX is the lenght of the PDU message we are sending. Take output obtained from this module!
> PASTE PDU output and press ^Z

This should output something like this:

+CMGS: 16

OK
