// Example of simple RF transmission.
//
// Intended for:
//   HW: - (DC)TR-72D + DK-EVAL-04x development kit
//
//   OS: - v4.06D
//
// Description:
//   - This example shows how to make a simple transmitter. It can be
//     tested with the E02-RX example.
//   - RF message is sent (and red LED flashes once) whenever the
//     pushbutton on the kit is pressed.
//   - Content of the messages = Application data.
//     (It is the 32 B array in EEPROM dedicated to user information
//     about the application - see the IQRF OS manual.
//     The "01234567890123456789012345678901" data array is used here.
//   - To lower power consumption the module utilizes the Sleep mode
//     and Wake-up on pin change for response to the button.
//     Wake-up on pin change is under user's control
//     and has to be enabled by the user when needed.
