    etherport-client

    Client-side virtual serial port for Rick Waldron's Etherport. Etherport-client is used to implement firmata-compatible boards and tethering hubs to control a board by a remote entity.

    Usage Examples

    Tethering a Johnny Five IO-Plugin

    Create an EtherPortClient with host and port properties referring to the peer transport endpoint of the EtherPort instance. Next, bind the resulting object to an IO-plugin using remote-io (see example below).

    var EtherPortClient = require('etherport-client').EtherPortClient;
    var RemoteIO = require('remote-io');
    var RaspiIO = require('raspi-io');
    var io = new RaspiIO();
    
    io.on('ready', function() {
        console.log("ready");
    
        var sp = new EtherPortClient({
            host: '192.168.178.70',
            port: 41234
        });
    
    
        //listen for remote firmata messages
        var remoteIO = new RemoteIO({
            serial: sp,
            io: io
        });
    });
    

    Tethering a Serial Port (Chaining)

    You can also simply chain Serial Port objects. For example, if you have a host with an Arduino board connected via USB and you want to access the Arduino board from a remote computer, you chain the Serial Ports on the host as follows.

    var EtherPortClient = require('etherport-client').EtherPortClient;
    var chainSerialPorts = require('etherport-client').chainSerialPorts;
    var SerialPort = require("serialport").SerialPort;
    
    chainSerialPorts(
        new EtherPortClient({
            host: '192.168.178.70',
            port: 41234
        }),
        new SerialPort("/dev/ttyUSB1", {
            baudrate: 57600
        })
    );
    

    Using StandardFirmataWiFi with ESP8266

    By default, StandardFirmataWiFi with ESP8266 is a TCP Server. Thus, you'll need a TCP client transport for J5.

    var five = require("johnny-five");
    var EtherPortClient = require("etherport-client").EtherPortClient;
    // update host to the IP address for your ESP board
    var board = new five.Board({
        port: new EtherPortClient({
            host: "10.0.0.17",
            port: 3030
        }),
        timeout: 1e5,
        repl: false
    });
    
    board.on("ready", function() {
        console.log("READY!");
        var led = new five.Led(2);
        led.blink(500);
    });
