If you can do this, the serial port hardware is working. 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.

2 Step 1: Connect to a terminal emulator using a PC.1 Step 0: Note whether your Raspberry Pi has Wireless/Bluetooth capability.What you type into the minicom terminal screen should appear on the serial PC terminal and vice versa.

Now run up minicom on the Raspberry Pi using Setup a connection using the serial port at 9600 baud. If you dont have this installed runĬonnect your PC to the Raspberry Pi serial port using an appropriate serial port adapter and wiring, then open Putty or a similar serial terminal program on PC side. In order you enable the changes you have made, you will need to reboot the Raspberry PiĪ great way to test out the serial port is to use the minicom program. The file will now look like thisĭwc_otg.lpm_enable=0 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait

Remove all references to ttyAMA0 (which is the name of the serial port). txtĭwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 root=/dev/mmcblk0p2 rootfstype=ext4 elevator=deadline rootwait You can disable it by editing the file / boot / cmdline. Arduino) at bootup, it will receive this information over the serial port, so it is up to you to decide whether this is a problem or not. Disabling this bootup information is optional and you may want to leave this enabled as it is sometimes useful to see what is happening at bootup. When the Raspberry Pi boots up, all the bootup information is sent to the serial port. T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100ĭisable it by adding a # character to the beginning.

Edit the file and move to the end of the file. This file has the command to enable the login prompt and this needs to be disabled. There are two files that need to be edited To enable the serial port for your own use you need to disable login on the port. Needless to say you will need some other way to login to the Raspberry Pi, and we suggest doing this over the network using an SSH connection. Arduino), the serial port console login needs to be disabled. To be able to use the serial port to connect and talk to other devices (e.g. Whilst this is useful if you want to login using the serial port, it means you can't use the Serial Port in your programs. By default the Raspberry Pi’s serial port is configured to be used for console input/output.
