 *  This example demonstrates usage of the AIR430BoostETSI library which uses
 *  the 430Boost-CC110L AIR Module BoosterPack created by Anaren Microwave, Inc.
 *  and available through the TI eStore, for the European Union.

 *  Description
 *  ===========
 *
 *  Acts as a simple transmitter for a star network. The sensor node can 
 *  transmit any type of message one-way using the broadcast address. To create
 *  multiple networks, simply change the address on the hub node and have the
 *  nodes in that network transmit to the assigned hub address.
 *
 *  ----------------------------------------------------------------------------
 * 
 *  This example assumes that two BoosterPacks will be used to showcase the 
 *  wireless radio communication functionality. This same code should be 
 *  programmed to both LaunchPad development kits.
 *
 *  This BoosterPack relies on the SPI hardware peripheral and two additional 
 *  GPIO lines for SPI chip-select and GDO0 for packet handling. They use pins 18 
 *  and 19 respectively. 
 *
 *  In the default configuration, this BoosterPack is not compatible with an 
 *  external crystal oscillator. This can be changed, if necessary, and would
 *  require reconfiguration of the BoosterPack hardware and changes to the 
 *  AIR430BoostETSI library. Refer to the BoosterPack User's Manual if necessary.
 *
 *  ETSI regulations must be followed when using this library. This example 
 *  limits the wireless duty cycle to 0.1% per ETSI.
 *
 *  For complete information, please refer to the BoosterPack User's Manual
