Serial GW to Raspberry USB connection, which tty ?



  • Hi everyone,
    I build a serial gateway (based on an Arduino nano v3) that I'll plug to a Raspberry that will house a NodeJS controller.

    I would like to have my Arduino to communicate with the rpi over usb.

    So my questions are :
    How can I tell the gateway to use the usb to send the data ? (I'm using the default serialgateway code)
    And on the RPI which tty should I connect to ?

    Thanks !

    Login to the RPi, plugin your USB serial device and type in a console:

    dmesg | grep tty
    

    which will return something like

    [145.376756] usb 5-1: pl2303 converter now attached to ttyUSB0
    

    The serial device is now available at /dev/ttyUSB0
