Getting Started With the MSP-EXPCC430RFx Experimenter Kit
2.3MSP-EXPCC430RFx User Experience
The MSP-EXPCC430RFx User Experience includes two projects:
1. Firmware applications that are pre-loaded on the MSP-EXP430F6137Rx Base Board and the MSPEXP430F5137Rx Satellite Board to demonstrate a stand-alone wireless network using the SimpliciTI
protocol.
2. When the Base Board is connected to the PC, the CC430 Wireless Network GUI program can be used
to enable visualization of the wireless sensor network.
2.4MSP-EXPCC430RFx Firmware Applications
The MSP-EXPCC430RFx User Experience application forms a star network using the SimpliciTI protocol.
The Satellite Board acts as the End Device, and the Base Board acts as the Access Point. The Base
Board can connect to a PC via the USB cable and transmit information back to the CC430 Wireless
Network GUI running on the PC.
2.4.1Access Point (AP or Hub)
The MSP-EXP430F6137Rx Base Board functions as the Access Point (also called the Hub), to create and
broadcast the star network using the SimpliciTI protocol. It allows compatible End Devices (EDs) to join
the network. The Base Board displays the status and sensor information of the devices on the network on
its LCD. The Base Board also provides its own status and sensor (temperature and light sensors)
information to the display. The Base Board captures more detailed network and device information and
provides that information to the PC GUI through the UART-USB bridge if the USB connection is enabled
between the board and the PC.
To start and operate the MSP-EXP430F6137Rx Base Board:
1. The MSP-EXP430F6137Rx Base Board displays "Access Point Up" on the LCD and starts accepting
connections from the Satellite Boards.
2. When a new ED successfully joins the network, the LCD briefly displays "Added New Device" and
resumes displaying network information.
3. When the network is active, the LCD displays the information of the AP and connected EDs. The first
digit on the LCD indicates the address of the device (a number for an ED, 'H' for the Hub or AP).
Subsequent digits show the temperature or RSSI value of the device.
4. The UP and DOWN buttons on the Base Board can be used to cycle through the device list.
5. The LEFT and DOWN buttons on the Base Board can be used to toggle the LCD to show the
temperature or the received signal strength indicator (RSSI) value from the EDs. If the AP (Hub) is
currently selected, the LCD switches between the temperature of the AP and the analog reading of the
light sensor.
www.ti.com
2.4.2End 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.
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.

4.3SimpliciTI™ RF Protocol
The SimpliciTI protocol is a simple low-power RF network protocol designed for small RF networks. Such
networks typically contain battery-operated devices that require long battery life, low data rate, low duty
cycle, and have a limited number of nodes talking directly to each other or through an access point or
range extenders. Access point and range extenders are not required but provide extra functionality such
as store and forward messages. The SimpliciTI protocol requires minimal MCU resource requirements,
which results in low system cost.
The SimpliciTI protocol was designed for easy implementation and deployment out-of-the-box on several
TI RF platforms such as the MSP430 family of low-power MCUs and the CC1xxx, CC25xx, and CC430
transceivers and SoCs.
For more information on the SimpliciTI protocol, visit www.ti.com/simpliciti.
4.4SimpliciTI Configuration for the MSP-EXPCC430RFx User Experience
The MSP-EXPCC430RFx User Experience application uses the SimpliciTI protocol in its star network
configuration to enable a sensor hub with the MSP-EXP430F6137Rx Base Board and multiple sensor
nodes (End Devices) with the MSP-EXP430F5137Rx Satellite Board. Minor configuration changes were
made to the stack to support CC430F6137 and CC430F5137 devices on SimpliciTI.
The SimpliciTI network is configured to accept up to 16 end devices. In the radio configuration, the
frequency settings are configured specifically for the frequency bands regulated by the geographical
locations. Specifically they are 915-MHz band for the US, 868-MHz band for Europe, and 433-MHz for
most other locations.
On the MSP-EXP430F5137Rx Satellite Board, two types of packets, heartbeat and alert, are prepared for
SimpliciTI transmissions. The MSP-EXP430F6137Rx Base Board running the AP stack is configured to
expect and process these two types of packets accordingly.
4.55xx/6xx Core Libraries
The CC430 devices are a member of the MSP430 5xx/6xx family devices. The 5xx/6xx family architecture
introduces several new core peripherals to enhance the device performance, optimize power consumption,
and allow for high flexibility and fine control of various aspects of the device core. These peripherals
include the Power Management Module (PMM), Unified Clock System (UCS), Port Map (PMAP), and
Flash modules. The 5xx/6xx core libraries provide a simple and efficient way of configuring and handling
these modules. The MSP-EXPCC430RFx User Experience utilizes the 5xx/6xx core libraries to properly
configure and start the CC430 core peripherals in the right sequence. The 5xx/6xx Core Libraries are
incorporated into the MSP430Ware DriverLib. More information and download links for MSP430Ware and
DriverLib can be found at http://software-
The MSP-EXPCC430RFx software package (MSP-EXPCC430RFx Software Download) includes the
CC430 Wireless Network GUI, which interfaces with the MSP-EXPCC430F6137Rx Base Board through
USB to display the wireless network based on the data received through the USB connection. In addition
to displaying the network topology, the GUI also offers vital information for the Access Point and the End
Devices including the supply voltage (VCC), temperature, and the End Devices' Received Signal Strength
Indicator (RSSI).
