micropython下ESP32 通过socket与后端通信

esp32代码

import socket
# 创建 UDP 套接字
udp_socket = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
# 设置目标 IP 和端口
IP = ("192.168.31.120", 6666)
# 要发送的消息
msg = "我是 ESP32 客户端"
# 发送消息
udp_socket.sendto(msg.encode("utf-8"), IP)
# 尝试接收数据
try:
    data, ip = udp_socket.recvfrom(128)
    print("收到的数据:", data.decode("utf-8"), ip)
except socket.timeout:
    print("超时未收到数据。")
finally:
    # 关闭套接字
    udp_socket.close()
