Re: Error Sending UDP Packet PostbyMicroController»Mon Jan 22, 2024 1:17 pm You're binding the socket to the same IP address you're trying to send data to ("192.168.1.3")? This is a) likely not what you want, unless you want the ESP to send data to itself, and b) not going...
socket.IPPROTO_UDP =17 原因:因为 SOCK_STREAM 套接字类型会自动选择 IPPROTO_TCP 和 SOCK_DGRAM - IPPROTO_UDP。 因此,这些常量的唯一实际用途是作为 setsockopt() 的参数。 ☀️UDPClient —— 客户端请求 这里博主特意用两种颜色区分STA和Client过程。 1.1 创建STA模式 import network sta_if = network.W...
const int PORT = 2500; //模块的端口号 WiFiUDP Udp; unsigned int localUdpPort = 2500; //本地的端口号,就是ESP8266-NodeMCU的端口号 char incomingPacket[255]; // buffer for incoming packets char replyPacket[] = "Hi there! Got the message :-)\r\n"; // a reply string to send back ...
**网络套接字**socket,封装了TCP/IP协议的通信编程接口,套接字,实际上是一个通信端点。需要主机IP和端口号才能建立连接。 UDP套接字编程模型 socket() : 创建套接字。 bind() : 绑定IP:Port connect() :将套接字连接到目的地址。 listen() : 监听 accept() : 接收连接请求。 send()/recv() 和 send...
In an ESP32C6 project I am sending UDP packets over ethernet to another device. I am trying to calculate the checksum of the UDP packet I have to send. To do this I have: Code: Untitled.c Select all static void convert_hex_to_uint8...

tcp/ipsocket编程udp编程算法 类型:指定套接字类型。 新套接字的类型描述类型,如TCP(sock_stream )或UDP (sock _ dgram )。 常用的socket类型有SOCK_STREAM、SOCK_DGRAM、SOCK_RAW、SOCK_PACKET、SOCK_SEQPACKET等。 全栈程序员站长 2022/09/14 7360 ...
Re: ESP32 连接WIFI路由器时UDP通信异常 Postbyliuzhifu»Tue Mar 24, 2020 12:17 pm Hi @ zhoujh, 使用中国电信天冀网关 2.0,型号 HS8145C 进行测试,配置如下: HS8145C 设置无线网络 PC 通过以太口连到 HS8145C,配置静态 IP 地址: 192.168.100.3 ...
now, at a later time, when all functionality is added and working (and that's a lot) I'll dive deeper into this. It's a bit tricky though, because I cannot measure the time spent between reception of the wifi frame and pushing the tcp/udp packet to my application using send/recv....
