MY xbee support transparent mode .So as you said me i try it to transmit my packets but still packets are spend a lot of time for transmission .As well as some packets with this mode was not received ....

hi !!!
Instead of this paq_sent->mode=BROADCAST; i use this paq_sent->mode= TRANSPARENT;
as well as i change my xbee from router api to router end device;

Do i something wrong ?

melisandroid,

This line is incorrect.

Could you post entire code? (or, at least, the sending part).

ho

this the code in loop .this code compile successfully

void loop(){

if (flag==1){

paq_sent=(packetXBee*) calloc(1,sizeof(packetXBee)); //desmeusi mnimis
paq_sent->mode=TRANSPARENT;
paq_sent->MY_known=0;
paq_sent->packetID=0x52;
paq_sent->opt=0;
xbeeZB.hops=0;
xbeeZB.setOriginParams(paq_sent,MAC_TYPE);

flag=0;

}

va = analogRead(ANALOG1); // Read the input ANALOG1 and store its value in val
va1 = (((millis()-previous) )/1000);
delay(200);

va2 = analogRead(ANALOG1); // Read the input ANALOG1 and store its value in val
va3=(((millis()-previous) )/1000);
delay(200);

va4 = analogRead(ANALOG1); // Read the input ANALOG1 and store its value in val
va5=(((millis()-previous) )/1000);
delay(200);

va6 = analogRead(ANALOG1); // Read the input ANALOG1 and store its value in val
va7=(((millis()-previous) )/1000);

sprintf(aux,"1-input:%d , %d -input:%d , %d -input:%d , %d -input:%d , %d , %c %c %c",va,va1,va2,va3,va4,va5,va6,va7,'%','\r','\n');

xbeeZB.setDestinationParams(paq_sent, "0013A200403A8BBF", aux, MAC_TYPE,DATA_ABSOLUTE);

xbeeZB.sendXBee(paq_sent);

Melisandroid,

This line paq_sent->mode=TRANSPARENT; is not correct. Mode can only be UNICAST or BROADCAST.

OK, now forget about transparent mode because only a few firmwares are compatible with this mode.(20xx (AT coordinator), 22xx (AT router), and 28xx (AT end device)).

Please, take a look at section 8.6.6 of Zigbee networking guide where an example of sending without API header is used.

Your sending part would be similar to next lines

Quote:

void setup()
{
  // Inits the XBee ZigBee library
  xbeeZB.init(ZIGBEE,FREQ2_4G,NORMAL);

  // Powers XBee
  xbeeZB.ON();

  //(...)

}

void loop {

  //(...)

  char* data;

  for(int c=0;c<50;c++) // Set the data
  {
    data[c]=’A’;
  }

  xbeeZB.send(“0013A2004030F66A”,data);

  //(...)

}

hi again ....

i try this but i the wasp-mote does not send anything to the gateway . I change the mac address from the example that you send me to my mac address .

melisa,

We send you a dummy code to show the basic shape for a code. PLease use next code and set your coordinator MAC. It is a simple test where you can see that a packet is sent every 20 milliseconds.

Please be sure your XBee Zigbee modules are properly configured as we mentioned in previous post.

Quote:

long timeShot;
char data[20];

void setup(){

  USB.begin();
  USB.println("start");

  // Inits the XBee ZB library
  xbeeZB.init(ZIGBEE,FREQ2_4G,NORMAL,UART1);

  // Powers XBee
  xbeeZB.ON();

}

void loop(){
  USB.println("loop");

  timeShot = millis(); // get timestamp
  sprintf(data,"%lu\n\r",timeShot);

  USB.print("millis: ");
  USB.println(data);

  // Set here your MAC
  xbeeZB.send("0013A20040614BA0",data);ç
}
