Question

修改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

这是我在爱迪生上运行的完整服务器代码。一切正常，我的绊脚石是从服务器向听众客户发送任何自定义事件。

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，现在是一个简单的网页

Answer 1

我遇到了同样的问题。根据{{3}}，接收机器人发出的事件连接到机器人而不是LED。

所以在你的客户改变

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

到

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

并将所有device.on( ...)改为robot.on( ...)。

使用Cylon.js和SocketIO发送自定义数据
