I am not receiving the data packet containing the temperature data from xbee end device sending data to coordinator.

Hi everyone,
I got problems when I tried to send temp and humid from dht11 to xbee coordinator via arduino ide. I am not receiving the data packet containing the temperature data from xbee end device sending data to coordinator. When Arduino is uploaded code, serial monitor displays some weird characters. I guess that the result was in incorrect format or sth … Pls help me.
This is electronic components I use:

  • Xbee S2C
  • Arduino UNO
  • Xbee Shield Arduino
  • DHT11 sensor
  • Xbee USB Adapter Ft232rl
    Configure Xbee in XCTU:
    Coordinator:
    Function: ZIGBEE TH Reg
    ID PAN ID: 1234
    SC Scan Channels: 7FFF
    JV Channel Verification: Disabled
    CE Coordinator Enable: Enabled
    AP API Enable: API enabled [1]
    Router:
    Function: ZIGBEE TH Reg
    ID PAN ID: 1234
    SC Scan Channels: 7FFF
    JV Channel Verification: Enabled
    CE Coordinator Enable: Disabled
    AP API Enable: API enabled with Escaping [2]
    Code Arduino:
    #include

#include

#include

#include “DHT.h”

#define DHTPIN 2

#define DHTTYPE DHT11

//Initialize XBee ZB client
XBee xbee = XBee();
//Payload byte array
uint8_t payload[8];
//Send to coordinator
XBeeAddress64 addr64 = XBeeAddress64(0, 0);
//Create request for XBee ZB
ZBTxRequest zbTx = ZBTxRequest(addr64, payload, sizeof(payload));

//Initialize DHT sensor module
DHT dht(DHTPIN, DHTTYPE);

void set_float_to_payload(float value, int index) {

uint8_t *value_array;

value_array = reinterpret_cast(&value);

for(int i=0; i

This sounds like an issue with your code. The characters you are seeing would be the Hex API Receive frames coming from the End device over the Coordinator.

Can you help me how to solve this problem?

What I would suggest is looking at the various 3rd party Arduino libraries that are designed to work with the XBee modules. That should take care of it.
