5. 点击安装

使用示例

import asyncio
import network
import micropython_websockets as websockets

# ── Wi-Fi 连接 ─────────────────────────────────────────────────────────────
async def connect_wifi(ssid, password):
    wlan = network.WLAN(network.STA_IF)
    wlan.active(True)
    if not wlan.isconnected():
        print("正在连接 Wi-Fi...")
        wlan.connect(ssid, password)
        while not wlan.isconnected():
            await asyncio.sleep(0.5)
    print("Wi-Fi 已连接，IP:", wlan.ifconfig()[0])

# ── WebSocket 客户端 ────────────────────────────────────────────────────────
async def main():
    await connect_wifi("你的WiFi名称", "你的WiFi密码")

    # 替换为 PC 的局域网 IP
    uri = "ws://192.168.1.107:8765"

    async with websockets.connect(uri) as ws:
        print("已连接到服务器:", uri)

        # 发送消息
        await ws.send("Hello from ESP32!")
        print("已发送: Hello from ESP32!")

        # 接收回复
        reply = await ws.recv()
        print("收到回复:", reply)

    print("连接已关闭")

asyncio.run(main())
