 2 | 使用 nodejs 模拟 scratch-link 实现硬件连接通讯
 3 | 
 4 | ### 使用方法
 5 | ```bash
 6 | git clone https://github.com/Micircle/scratch-node-link.git
 7 | npm i
 8 | npm start
 9 | ```
10 | 将 ```scratch-gui/node_modules/scratch-vm/src/util/scratch-link-websocket.js``` 中
11 | 
12 | ```javascript
13 | this._ws = new WebSocket('wss://device-manager.scratch.mit.edu:20110/scratch/ble');
14 | ```
15 | 改为
16 | ```javascript
17 | this._ws = new WebSocket('ws://127.0.0.1:20110/scratch/ble');
18 | ```
19 | 就可以连接 microbit 了
20 | 
21 | Windows 如果 npm 安装依赖失败，请查看：https://github.com/noble/noble 的说明
22 | 
23 | ### 以 microbit 扩展为例，了解 Scratch 硬件通讯流程
24 | 想知道 Scratch 3.0 怎么使用 micro:bit 扩展，请查看 microbit 扩展的帮助页 https://scratch.mit.edu/microbit 。本文是对 Scratch 硬件连接通讯过程的分析。
25 | 
26 | 在浏览器中运行的 Scratch，无法直接与硬件设备通讯（除非使用实验中的 Bluetooth 等功能），需要一个本地服务来帮助它来实现，这就是 Scratch Link 的作用。Scratch Link 的主要功能就是与 Scratch 通讯、与硬件设备通讯。
27 | 
28 | <img src='./scratch-link-1.png'/>
29 | 
30 | Scratch Link 会开启一个本地 WebSocket 服务器，Scratch 通过 WebSocket 与 Scratch Link 进行连接通讯，使用 WebScoket 服务端和客户端都可以主动推送消息，想要详细了解的可以查看阮一峰老师的 《WebSocket 教程》[http://www.ruanyifeng.com/blog/2017/05/websocket.html]。
31 | 
32 | Scratch Link 会监听 Scratch 发来的连接请求，根据请求的路由来与不同的设备进行通讯，目前支持两个路由 scratch/ble 和 scrattch/bt，分别对应低功耗蓝牙和蓝牙。
33 | Scratch Link 在接收到 Scratch 的连接请求后，双方就会建立起 socket 通道开始通讯，Scratch 会向 Scratch Link 发送命令（command） 或请求（request）如：检测设备、连接设备、向设备写入数据、读取设备数据、订阅设备信息、取消订阅、断开设备等。Scratch 也会响应（response）Scratch Link 发来的命令请求如：发现设备、设备数据更新、设备断开等。
34 | 
35 | 以 microbit 为例，流程如下：
36 | 1. Scratch 会使用路由 scratch/ble 向 Scratch Link 发起连接请求。两者握手成功后建立起 WebSocket 连接。
37 | 2. Scratch Link 根据路由选择开启与低功耗设备通讯的会话 BLE Session。
38 | 3. Scratch 发起检测 microbit 设备的命令。
39 | 4. Scratch Link 接收到命令，BLE Session 开始检测设备。
40 | 5. BLE Session 发现设备，通过 WebSocket 向 Scratch 发送检测到设备的信息。
41 | 6. Scratch 接收到发现的设备，开始发送连接请求。
42 | 7. Scratch Link 接收到请求，BLE Session 开始连接设备。
43 | 8. BLE Session 连接成功，并告知 Scratch。
44 | 9. Scratch 得知连接成功，发起读取或写入请求。
45 | 10. Scratch Link 接收到请求，BLE Session 开始读取或写入数据到设备，并订阅设备的信息，在接收到信息时发送给 Scratch。
46 | 11. 断开设备时，关闭 BLE Session，关闭 WebSocket

50 | 详细实现可以查看使用 nodejs 的代码实现。
51 | 
52 | 除了 ble 连接外，也可以用同样的方式实现串口 serialport 的连接通讯。
