使用Cylon.js和SocketIO发送自定义数据

Sending custom data using Cylon.js and SocketIO

本文关键字：自定义数据 SocketIO Cylon js 使用更新时间：2024-01-01

修改了我的代码以遵循此处的示例

https://github.com/hybridgroup/cylon-api-socketio/tree/master/examples/robot_events_commands

这是我在edison上运行的完整服务器代码。一切正常，我的绊脚石是将任何自定义事件从服务器发送到侦听客户端。

var Cylon = require('cylon');
Cylon.robot({
    name: 'chappie',
    connections: {
        edison: { adaptor: 'intel-iot' }//,
    },
    events: ['range'],
    commands: function () {
        return {
            send_range: this.sendRange    
        };
    },
    devices: {
        maxbotix: { driver: 'maxbotix', pin: '0' },
        led: { driver: 'led', pin: 13 }
    },
    work: function (my) {
        var range = 0;
        every((0.1).seconds(), function () {
            range = my.maxbotix.range();
            this.sendRange(range);
        }.bind(this));             
    },
    sendRange: function(data) {
        this.emit('range', { info: data });    
    }
})
Cylon.api(
    'socketio',
    {
        host: '0.0.0.0',
        port: '3000'
 });
Cylon.start();

这是我的客户，一个简单的网页现在

我也遇到了同样的问题。根据cylon.js博客的说法，要接收机器人发出的事件，请连接到机器人，而不是LED。

所以在你的客户更改

device = io('http://<actual ip of edison>:3000/api/robots/chappie/devices/led');

至

robot = io('http://<actual ip of edison>:3000/api/robots/chappie');

并且为了一致性将所有的CCD_ 1改变为CCD_。
