What do you want to do ? As. Far as the printf statement .. ing R =rand(); R = R & oxff; Printf ("%d",R); value between o -> 255

Also you need to cross over tx and rx, (also rx and tx).

Enjoy

Ceri.

Could you skip the use of printf() and scanf() all together and just send/receive the bytes raw? printf() might be overkill if the data being sent between the two devices never needs to be read by a human.

#include "mbed.h"

Serial SerialToMbed(p9, p10);

// Code to send byte from one mbed to another
void SendByte(char ByteToSend)
{
    SerialToMbed.putc(ByteToSend);
}

// Code to receive byte from other mbed
char ReceiveByte()
{
    return SerialToMbed.getc();
}

// Insert you own main function with the logic that you require
