I assume from the title in that console window that the other side is a 32 bit or 64 bit processor.

What size is int? For which processor?

[Coding_Badly]

Kudos for using memcpy. That is the right choice.

@akidou

#define   BYTE_SIZE   8

char messageBuffer[BYTE_SIZE];

typedef struct
{
   int weight;
   int height;
} Person_ard;

are you assuming your int are 4 bytes ? (only 2 bytes on UNO, will be 4 on ARM architecture). Mind also endianness

64 bits, leonardo board
did I made a mistake when declaring the incoming data size 255 ?
i've found that "Person struct" size is 8 thats why I wrote #define BYTE_SIZE 8

printf("sizeof(me)=%d\n",sizeof(me));

have you tried to print the byte stream you get on the Arduino side ?
endianness might come and bite you. Arduino is little endian
