Getting Started With the MSP-EXPCC430RFx Experimenter Kit
2.4.2
End Device (ED)
The MSP-EXP430F5137Rx Satellite Board functions as an End Device on the star network that is created
using the SimpliciTI protocol.
1. When supplied with power, the Satellite Board seeks out compatible network broadcasts from an AP
and attempts to join the network. During this phase, the on-board LED slowly toggles on and off to
indicate each attempt.
2. After it successfully joins the network, the Satellite Board periodically measures its temperature and
transmits its heartbeat message to the AP. Each transmission is indicated by the brief pulse of the
LED.
3. Additionally, the push button can be used to transmit an Alert message, which causes the AP to show
this ED's information on the LCD. The exclamation mark (!) on the LCD also briefly turns on, further
highlighting the Alert message to the user.
2.5
CC430 Wireless Network GUI
The included CC430 Wireless Network GUI is designed to provide more detailed information as well as
visual presentation of the network and device information. The GUI requires a PC USB connection from
the MSP-EXPF6137Rx Base Board. The Base Board captures all status and sensor information from the
devices (including the AP itself) and relays the prepared packets to the PC GUI. The GUI displays the
wireless network in the star topology, showing the connected and disconnected devices along with their
status information such as RSSI (relative distance from the AP), temperature, and remaining battery life.
