Arduino + Xbee + Sensor ultrasonico

-

muy buenas! soy nuevo en este foro, pero siempre ando leyendo tips y ahora necesito uno xd tengo un proyecto que consta de arduinos sensores y xbee. basicamente quiero que un arduino con xbee lea el programa y que el otro arduino con xbee pero ahora mas el sensor y el buzzer lo ejecute.. el programa consta que suene el buzzer cuando se coloque un objeto a  cierta distancia del sensor, es un codigo sencillo lo probe sin el xbee y funciona, pero cuando trato de hacer comunicacion entre estos 2 mediante el arduino no puedo :(
tengo el xbee asi:

xbee       arduino
vcc ---> 3.3v
dout --> tx
din ---> rx
gnd --> gnd

y el sensor mas buzzer conectados los otros pines del arduino..
alguien hecho algo asi? me falta algo? :( pls
muchas gracias.
pd: probe que haya comunicacion entre los 2 xbee y si hay! (uno coordinador y el otro router/end divice)

intercambia los cables tx y rx

hey everyone, i'm trying compile simple code on rpi3 using geany. code written using code::blocks on windows , working without problem. errors i'm getting are: untitled.c:33:5: error: ‘for’ loop initial declarations allowed in c99 or c11 mode , untitled.c:33:5: note: use option -std=c99, -std=gnu99, -std=c11 or -std=gnu11 compile code understand code not problem way i'm compiling it. can give me advice? you need add 1 of suggested options compile command configured in geany, in menu.. build -> set build commands add "-std=c99" after "gcc" in compile , build boxes. (i'm looking on mint pc expect version on pi same). petero raspberrypi
