plz help ......
my code

void loop()
{
int m[9];
static int n=0;
int bytes_read = 0;
while (bytes_read < 9)
{
if (Serial.available() > 0)
{
m[n]=Serial.read();
bytes_read ++;
n++;
}

}
Serial.println(m[8]);
n=0;
}

You only print the last element of the m array. Try this:

Serial.println(m[7]);

Do you see that 04 you're missing?

yes..i need 04 D2.it is a data frame..04 D2 is hexadecimal of decimal number 1234...bt i got only 210 instead of 1234..bcs only take D2...deimal of hexD2 is 210...i need fully 04D2....kindly help

i got ans..........

#include <SoftwareSerial.h>
SoftwareSerial max232(0,1);
int num;
void setup()

{
Serial.begin(115200);
max232.begin(115200);
}

void loop()
{
int m[9];
static int n=0;
int bytes_read = 0;
while (bytes_read < 9)
{
if (Serial.available() > 0)
{
m[n]=Serial.read();
bytes_read ++;
n++;
}

m; }
num=((m[7]<<8) | m[8]);
Serial.println(m[8]);
Serial.println(num);
n=0;

}
