The second one sends an array of bytes, stopping when it reaches a null value in the array. (This would usually be used to send null-terminated strings.)If you may need to send different types of data I generally like to use a simple protocol where the first n-bytes is a type identifer (can be 1, 2 or 4 bytes), the next 4 bytes indicates the length of the data and the remaing x-bytes is the data itself.The serial port is a low-level way to send data between the Raspberry Pi and another computer system. There are two main ways in which it can be used: Connecting to a PC to allow access to the Linux console.Changing serial port options. When the incoming data is not readable, this might have two causes: Device outputs binary data instead of ASCII; Device outputs ASCII data, however, the serial baud rate or data format setting is incorrect; The second problem can be fixed by changing the baud rate or the data format.
