One RF target board serves as the end point and the other serves as the access point. The end-point target board (connected to the hardware via the six-pin connector, as previously mentioned) receives data via UART (9600 baud) and transmits it via the SimpliciTI protocol to the access point. When not receiving bytes from the UART, the RF target turns off the antenna/transceiver and goes into LPM3 to prevent battery drain. The access point target board (connected to the eZ430 emulator plugged into the USB port of a PC) receives data via the SimpliciTI protocol from the end point. It then outputs that data via backchannel UART-over-USB, and the data can be displayed on a HyperTerminal on the PC at the rate of 9600 baud.

SimpliciTI™ - RF Made Easy

Network Protocol for Sub-1 GHz, 2.4 GHz and IEEE 802.15.4 RF ICs
SimpliciTI™ is a low-power RF protocol aimed at simple, small RF networks. This open-source software is an excellent start for building a network with battery-operated devices using one of TI’s low-power RF System-on-Chips (SoC) or the MSP430 ultra-low-power MCU and a TI RF transceiver. SimpliciTI was designed for easy implementation and deployment out-of-the-box on several TI RF platforms such as the MSP430 MCUs and the CC1XXX/CC25XX transceivers and SoCs. The sample applications run out-of-the-box on the SmartRF boards with CC2430EM and CC2520EM, as well as the MSP430FG4618/F2013 Experimenter Board with the CC1100EM, CC1101EM, or CC2500EM.
The latest version of SimpliciTI now supports the new CC2530 and CC430 solutions from TI.
