Raspberry Pi, RPi in short It is a synchronous serial data link standard and is used for short distance single master communication between devices The number one benefit of hooking up to the Raspberry Pi 4 over the UART is that you get to see the wealth of debugging information that is printed out when Linux first tries to boot On the Pi 3 and 4 the UART is, by default, used for Bluetooth and you may need to add "dtoverlay=miniuart-bt" to "/boot/config Tech Support¶ Please submit any technical issue into our forum The reason for this is because by default, the serial port is used for Console Input/Output, and the kernel also sends diagnostic information to this port when booting the system /dev/serial0 is a symlink which always refers to the primary UART (if enabled)
