Asking send data using mbed+xbeepro

hello everyone, i have been trying to send data from ADXL345, ITG3200, and LM35 using mbed+xbeepro in transmit side and xbeepro+xbeeexplorer+software xctu. this is my code

ADCScode

#include "ADXL345.h"
#include "ITG3200.h"

//determine pinout
ADXL345 accelerometer(p5, p6, p7, p8);
Serial pc(USBTX, USBRX);
ITG3200 gyro(p9, p10);
Serial xbee1(p13, p14);
AnalogIn LM35(p19);

//also setting unused analog input pins to digital outputs reduces A/D noise a bit 
DigitalOut P16(p16); 
DigitalOut P17(p17); 
DigitalOut P18(p18); 
//DigitalOut P19(p19); 
DigitalOut P20(p20);

int main() {

    int readings[3] = {0, 0, 0};
    int tempC;
    char send[7];
    
    pc.printf("Institut Teknologi Telkom Satellite Society :)");
    pc.printf(" DOA MAMA ", accelerometer.getDevId());

    //Go into standby mode to configure the device.
    accelerometer.setPowerControl(0x08);

    //Full resolution, +/-16g, 4mg/LSB.
    accelerometer.setDataFormatControl(0x0B);
    
    //3.2kHz data rate.
    accelerometer.setDataRate(ADXL345_3200HZ);

    //Measurement mode.
    accelerometer.setPowerControl(0x08);
     gyro.setLpBandwidth(LPFBW_42HZ);
     
    while (1) {
        //conversion to degrees C - from sensor output voltage per LM61 data sheet 
        tempC = ((LM35*3.3)-0.6)*100.0; 
        //convert to degrees F 
        //tempF = (9.0*tempC)/5.0 + 32.0; 
        
        //print current temp and count the time 
        pc.printf("%i C\n\r", tempC); 
        wait(1);
        
        accelerometer.getOutput(readings);
        
        //13-bit, sign extended values.
        pc.printf("%i , %i , %i\n\r", (int16_t)readings[0], (int16_t)readings[1], (int16_t)readings[2] );

        //Arbitrary wait for printf clarity
        pc.printf("%i , %i , %i\n", gyro.getGyroX(), gyro.getGyroY(), gyro.getGyroZ());
        
        //convert integer to char
        send[0]=(int16_t)readings[0]&0xFF;
        send[1]=(int16_t)readings[1]&0xFF;
        send[2]=(int16_t)readings[2]&0xFF;
        send[3]=gyro.getGyroX()&0xFF;
        send[4]=gyro.getGyroY()&0xFF;
        send[5]=gyro.getGyroZ()&0xFF;
        send[6]=tempC&0xFF;
        
        //send data throudh serial
        xbee1.putc(send[0]);
        xbee1.putc(send[1]);
        xbee1.putc(send[2]);
        xbee1.putc(send[3]);
        xbee1.putc(send[4]);
        xbee1.putc(send[5]);
        xbee1.putc(tempC);

    }
}

i converted all the integer output into char using mask ($0xFF), and then i transmitted all the results of the sensors over xbee. but in xctu software, all the datas appear as a "dot"(like this: "......."). i sent 7 datas and result 7 dots long. is there any idea to show as their meant to be? thank you
