The default Wheezy installation sends console messages to the serial port as it boots, and runs getty so you can log in using the terminal emulator. ![]() Step 1: Connect to a terminal emulator using a PCįollow the instructions at RPi_Serial_Connection#Connections_and_signal_levels, and RPi_Serial_Connection#Connection_to_a_PC, so that you end up with your Pi's serial port connected to a PC, running a terminal emulator such as minicom or PuTTY. On these wireless devices, it is possible switch the GPIO serial port back to /dev/ACM0 with `/boot/config.txt` directives by disabling bluetooth with `bdtoverlay=`pi3-disable-bt` or by forcing the bluetooth to use the mini-UART with `dtoverlay=pi3-miniuart-bt`. Step 0: Note whether your Raspberry Pi has Wireless/Bluetooth capabilityīy default the Raspberry Pi 3 and Raspberry Pi Zero W devices use the more capable /dev/ttyACM0 to communicate over bluetooth, so if you want to program the serial port to control the IO pins on the header, you should use the auxiliary UART device /dev/ttyS0 instead. ![]()
