How to convert a byte array into a string in CAPL?

I have a byte array and I need to print the elements in a single line.

I tried using 'snprintf()' but it won't take a byte array as its input parameter.

I tried copying the byte array into an integer array and then used the snprintf(), but instead of printing the HEX values, corresponding ASCII values are printed.

You can try this code :

variables
{ 
  int ar[100];
}

on diagResponse TCCM.*
{
  char tmp[8];    // Temporary buffer containing single HEX value
  char out[301];  // Bigger output string and "local" to function
  // Better to place them there (i and response) if they are not global
  int i;
  byte response[100];
  
  out[0] = 0;     // Clear output string
  
  s1 = DiagGetPrimitiveData(this, response, elcount(response));

  for (i = 0; i < s1; i++)
  { 
    ar[i] = response[i];
    snprintf(tmp, elcount(tmp), "%.2X ", response[i]);  // byte to HEX convert
    strncat(out, tmp, elcount(out));  // Concatenate HEX value to output string
  }

  write("HEX Response : %s", out);
}
