TrafTerm is an Android Intelligent Traffic Controller Handset, a terminal application for communicating with Traffic Light equipment.

The program communicates via Bluetooth and a Bluetooth Serial RS232 adapter is required. For details of constructing both a Roving Networks and a ConnectBlue adapter and also a User Guide see my website.
