4. Using SMS in your personal projects And programmers all know how to read from databases 5. Using SMS in your personal projects And programmers all know how to read from databases mostly 6. Using SMS in your personal projects So, why not use something which would read SMS messages from a mobile phone, and insert them into a database for processing? 7. Using SMS in your personal projects Of course, I couldn't find one so I wrote one! 8. Using SMS in your personal projects I wanted to help users who like exchanging SMS with microblogging sites (like Twitter or Identi.ca) 9. Using SMS in your personal projects But couldn't because they turned it off 10. Using SMS in your personal projects Or didn't have it in my country for my network 11. Using SMS in your personal projects It also meant I had a project to work on :) 12. Using SMS in your personal projects Enter smsToLaconica 13. Using SMS in your personal projects Crap name huh? 14. Using SMS in your personal projects Laconica is the microblogging software I was writing for initially 15. Using SMS in your personal projects My first draft only took SMS messages and sent them to Laconi.ca based sites e.g. Yey! I'm talking at #BarcampLiverpool 16. Using SMS in your personal projects Next I wanted to also send SMSs back from my direct messages and replies e.g. @jontheniceguy I'm loving it so far! 17. Using SMS in your personal projects (I hope that's what I'll read!) 18. Using SMS in your personal projects So, I had to learn about how to send and receive SMS messages. 19. Using SMS in your personal projects It's actually pretty easy. 20. Using SMS in your personal projects Kinda... 21. Using SMS in your personal projects The mobile phone acts like a modem you talk to it with AT commands 22. Using SMS in your personal projects AT+CMGL=All or AT+CMGL=4 These commands retrieve all messages on your phone, depending on the modes your phone will accept PDU or Text 23. Using SMS in your personal projects Modes in SMS 24. Using SMS in your personal projects PDU is a binary format it's 7 bit binary, stored in 8 bit chunks converted to hex. 25. Using SMS in your personal projects The messages look like this: 07911326040000F0040B911346610089F600002080629 17314080CC8F71D14969741F977FD07 26.

Using SMS in your personal projects I found it really hard to send SMS messages in PDU mode, so I switched my focus to TEXT mode Which is just normal text 28. Using SMS in your personal projects You don't need to know all the detail now, but it does work 29. Using SMS in your personal projects And you don't ACTUALLY need to be working with Laconi.ca or identi.ca to use the code in your own site! 30. Using SMS in your personal projects It's just a PHP script which you run as a daemon! 31. Using SMS in your personal projects (You might need to tweak it a bit!) 32. Using SMS in your personal projects The code is released under the Affero General Public License (v3), but if you contact me directly, I'll consider re-licensing for your project 33. Using SMS in your personal projects Or, you could just look at lib_text.php or lib_pdu.php in the source code 34. Using SMS in your personal projects So, where is the source code? 35. Using SMS in your personal projects Sourceforge of course! 36. Using SMS in your personal projects It's at http://sourceforge.net/projects/laconicatools 37.

Using SMS in your personal projects (Nokia's do well on this, and most of us have an old one kicking around) 43. Using SMS in your personal projects I use a Linux daemon called ser2net to expose the serial port via telnet (on port 2000) 44. Using SMS in your personal projects And then you need PHP, and a database that PHP knows how to talk to (which is most of them!) 45. Using SMS in your personal projects And that's it 46. Using SMS in your personal projects Any questions?
