You can also find sellers in venues like eBay and AliExpress using search queries with “ESP32” and “QFN”, “SMT”, “SMD”, “package”, “bare” or “raw”; also using the full identifier (such as “ESP32-D0WDQ6” or “ESP32-D2WD”) in search queries may prove fruitful. ...

socket.SOCK_RAW #这是原始套接字,允许对底层协议(TCP/IP)直接访问 方法的使用: sk=socket.socket() #括号里面包含两个参数,一个参数默认是ip地址蔟的socket.AF_INET,也就是IPv4;还有一个默认是传输TCP协议 ,也就是socket.SOCK_STREAM; sk.bind(()) #最里面的括号里包含两个参数,分别是客户端的ip地址与...
红色两个框里面就是收到的raw数据,也就是一个HTTP请求就是往tcp里写这些东西。 那么我们开始模拟下这个http协议 sprintf(p_request, "POST %s HTTP/1.0\r\nHost: %s:%d\r\nContent-Length: %d\r\nUser-Agent: ESP32\r\nAccept: */*\r\n\r\n", url->path, url->host, url->port,length) 这个...
domain:为地址族,也就是 IP 地址类型,常用的有 AF_INET 和 AF_INET6; type:数据传输方式/套接字类型,常用的有 SOCK_STREAM(流格式套接字/面向连接的套接字) 和 SOCK_DGRAM; protocol:为协议类型,常用的有 IPPROTO_TCP 和 IPPTOTO_UDP,分别表示 TCP 传输协议和 UDP 传输协议; 返回值为套接字。
