Paired Wireless Sensor / Gateway Demonstration using 2.4 GHz AIR Modules with TI SimpliciTI

In this demonstration, we use TI’s EZ430-RF2500 demonstration kit — together with Anaren’s 2500R24A-EZ4x Target Boards and TI’s SimpliciTI protocol -to manage a powered-on receiver and battery-operated sleeping transmitter that are paired in the field. The Transmitter then simulates a sensor input by transmitting 12-bytes at a 16Hz rate to the receiver — and sleeping otherwise. The Transmitter is optimized for low power consumption to maximize battery life. The Receiver is normally in a listening mode receiving, messages from the Transmitter, checking them for errors, and then moving the information out the UART for demonstration purposes.

At manufacturing time, all the Receivers are identically programmed, as are all the Transmitters. Each Receiver / Transmitter is programmed with a unique serial number that is later used in the pairing process. When originally programmed, the RX and TX units are unpaired — and will go to deep sleep awaiting pairing.
