Using Tropo SMS gateway with BusTracker

SMS Bustracker works with “Obama Phone”


A pinch of Tropo, a dash of Bustracker, fold in a pound of jata with PHP, bake for an hour and you have jata-sms.

My Android smartphone suffered a breakdown last week.    New parts should arrive soon.  But in the meantime, I was at a loss without my favorite Android app jata.  I use it to get bus arrival times with the local WRTA Bustracker.  Bustracker has a text message interface, and I thought I would try that with the backup TracFone (Safelink Obamaphone[1]).  That didn’t work.  The TracFone Terms and Conditions states that “TracFone does not generally participate in Premium SMS services or campaigns.”  The Bustracker SMS number is 41411, a shortcode for Textmarks, and I guess Textmarks is a premium service.  Then, I remembered Tropo, a gateway for voice and SMS.  It offers a free developer account and phone number, and now I had a motivation to work with it.

My first home computer was a TRS-80 Model 1 and it evolved into this S-100 system with NorthStar Z80 CPU board, floppy and hard disk controllers, and serial and printer ports.
