Arduino programación wireless con Xbee oficial. Cuarta parte.

El código del sketch que debe correr en el Arduino Master para hacer la programación remota con el shield de Xbee es:

//MAKE AN ARDUINO WIRELESS PROGRAMMING WITH XBEE SHIELD LIBELIUM
//RemoteXbee v1.0
//RELYNXANDO Marz-11
//This example code is in the public domain.
#include <xbeefg.h>
#include <newsoftserial.h>
// SH + SL of your remote radio Slave Arduino XBeeAddress64(SH,SL)
// in my case SH=0x0013a200 and SL=0x4049CC62
XBeeAddress64 remoteAddress = XBeeAddress64(0x0013a200, 0x4049CC62);
// Define NewSoftSerial TX/RX pins
// Connect Arduino pin 6 to TX of usb-serial device
uint8_t ssRX = 6;
// Connect Arduino pin 7 to RX of usb-serial device
uint8_t ssTX = 7;
xBeeFG XBeeNSS = xBeeFG( ssRX, ssTX );
// Software UART to communicate with the Xbee module
NewSoftSerial nss(ssRX, ssTX);

// Configure remote Xbee to API Mode (AP=2)

char payload[20];   

// unless you have set DH/DL for 64 bit this will be received as a RX16 packet
Tx64Request tx64 = Tx64Request(remoteAddress, (uint8_t*)payload, sizeof(payload)); 

// This will contain the status responses of that the XBee receives
TxStatusResponse txStatus = TxStatusResponse();
