Explanation / Answer

This function been built in arduino and to be used for changing array to string :-

void array_to_string(byte array[], unsigned int len, char buffer[]){

for (unsigned int i = 0; i < len; i++) {

byte nib1 = (array[i] >> 4) & 0x0F;

byte nib2 = (array[i] >> 0) & 0x0F;

buffer[i*2+0] = nib1 < 0xA ? '0' + nib1 : 'A' + nib1 - 0xA;

buffer[i*2+1] = nib2 < 0xA ? '0' + nib2 : 'A' + nib2 - 0xA;

}

buffer[len*2] = '';

}

double data[] = {1000.0, 2.0, 3.4, 7.0, 50.0, 10100.0, 112.0, 33.4, 17.0, 510.0, 11000.0, 22.0, 36.4, 79.0, 570.0, 12.0};

char str[32] = "";

array_to_string(data, 16, str);

Serial.println(str);

Serial.println("");

Now based on above given function,we can make array to string function based in this function by adding doble type array with length 16 ------->

double data[] = {1000.0, 2.0, 3.4, 7.0, 50.0, 10100.0, 112.0, 33.4, 17.0, 510.0, 11000.0, 22.0, 36.4, 79.0, 570.0, 12.0};//this line added in code above

Now when we call function array_to_string(data, 16, str), it will convert double type array data[] to string str and print in ardunio.
