Re: Trying to turn on a led with the PC to XBee/Arduino case

[Andrew Rapp]

Hi Diego,

The error you show below (com.rapplogic.xbee.examples.ApiAtExample) is unrelated to the java code that you posted, so you are not running your code. Also you are mixing series 1 and 2 code. You java is using series 1 and Arduino series 2, so that would never work.

Hi

I am trying to combined case 1 and case 2(the ones of the wiki). Turn off a led sending signals from the PC but using arduino.

Still doesn't work. Completely new with the API.

This is my java code

xbee.open("/dev/ttyUSB0", 9600);

XBeeAddress16 destino = new XBeeAddress16(0x0013A200, 0x408B2E54);

                        int[] payload = new int[] { 90, 180 };

                        TxRequest16 tx = new TxRequest16(destino,payload);

                        TxStatusResponse status = (TxStatusResponse)xbee.sendSynchronous(tx);

                        if (status.isSuccess()) {

                            System.out.println("Se conecto");

                        }

                        else

                        {

                            System.out.println("No se conecto");

                            

                        }

And this is my arduino code

XBee xbee = XBee();

uint8_t payload[] = { 1, 0 };

XBeeAddress64 address= XBeeAddress64(0x0013A200, 0x408b2E66);

ZBTxRequest tx = ZBTxRequest(address, payload, sizeof(payload));

TxStatusResponse txStatus = TxStatusResponse();

int BELL = 2;

void setup() {

  xbee.begin(9600);

  pinMode(BELL, OUTPUT);

  digitalWrite(BELL, HIGH);

}

void loop() 

  {

    int signal;

    xbee.send(tx);

    if (xbee.readPacket(5000)) {                 

        if (xbee.getResponse().getApiId() == TX_STATUS_RESPONSE) {

           xbee.getResponse().getZBTxStatusResponse(txStatus);

             

           if (txStatus.getStatus() == SUCCESS) {

                digitalWrite(BELL, LOW);

                delay(10000);

                digitalWrite(BELL, HIGH);

           } else {

              

           }

        }      

    } else {

    

    }

    delay(5000);

  }

Both code compiles, but doesn't work. I am getting this exception in my java code

[ERROR] [com.rapplogic.xbee.examples.ApiAtExample] at command failed 

java.lang.IllegalArgumentException: input value [1286656] is larger than a byte

Thanks for your time

Hi Andrew I change the code and left it with the same name. I

thought that for using Series 2 was this way

                       XBeeAddress16 destino = new XBeeAddress16(0x0013A200, 0x408B2E54);

                        int[] payload = new int[] { 90, 180 };

                        TxRequest16 tx = new TxRequest16(destino,payload);

                        TxStatusResponse status = (TxStatusResponse)xbee.sendSynchronous(tx);

Still not sure of that
