进行TCP透传链接时遇到TCP ERROR CLOSED 一般遇到这种情况,如果硬件其他步骤都配好的话,导致不能正常运行的应该就是电脑的防火墙问题了。由于使用电脑作为TCP服务器,而一般情况下电脑防火墙会将一些不怎么常见的端口进行阻挡,从而导致虽然电脑打开了TCP服务器但是ESP8266无法接收到。如果是这种问题的话,解决的办法有两种:...
1.ESP8266建立TCP连接确出现错误AT+CIPSTART=“TCP”,“10.161.13.180”,8080 ERROR CLOSED 问题分析 (1)是否连接的是同一个局域网(WIFI之类的) (2)关闭防火墙和允许程序访问指定端口 如果输入 AT+CIPSTART=“TCP”,“14.215.177.38”,80 将IP和端口改成百度服务器的80端口时,发现可以正常连接,但是与本机确无...

practically, any server I put there gives this same error. The issue must be with the VPS itself, or some firewall in front of it filtering TCP packets. I have no idea but I will try to find out, since I am not the owner providing that VPS. ...
首先要设置服务器(手机、PC、模块都可以模拟服务器) 模式,tcpAT指令设置模块进入server调试助手连接模块。1.模块作为服务器, IP,端端为tcp server模式,模块作为客户端向pc申请端口(AT+CIPSTART=pc作为服务器,设置pc 端口) 模式,等待模块连接)3.手机作为服务器和pc作为服务器原理相同(手机默认server 透传模式测试4....
