ESP8266 WIFI模块 - 照片和QUOT;准备＆QUOT;但不响应AT命令 [英] ESP8266 Wifi Module - prints "ready" but not responding to AT commands

问题描述

刚收到我的第一ESP8266 WiFi模块与有些兴奋。不过，我一直无法与之充分沟通。我已经通过USB转串口线连接模块到我的电脑，我通过电源单独供电（3.3V）模块。

Just received my first ESP8266 wifi module with some excitement. However I've been unable to fully communicate with it. I have connected the module to my computer via a usb to serial cable and I'm power the module via a separate power supply (3.3v).

模块了，我收到以下信息（通过腻子或与Arduino的串口监视器窗口）开机后：

After powering the module up I receive the following information (via PuTTY or and Arduino serial monitor window):

[Vendor:www.ai-thinker.com Version:0.9.2.4]

ready

我已经尝试了各种发送AT命令例如

I have tried sending various AT commands e.g.

AT+RST

但我没有得到任何回应。使用Ctrl + M和Ctrl + J键在腻子没帮助的。

But I get no response. Using ctrl+m and ctrl+j in putty didn't help either.

请看看我的YouTube视频如果有所帮助：

推荐答案

请确保您有油灰或配置同时发送一个换行符Arduino的串行控制台 \\ n 和回车 \\ r 字符。因此，AT + RST实际上最终被 AT + RST \\ r \\ n 。这花了我一点，当我第一次收到我的ESP8266模块。在Arduino的串行控制台这个选项是在窗口的底部。我可以在视频中看到你有它设置为无行结束。希望这会为你。

Make sure that you have putty or the Arduino serial console configured to send both a newline \n and a carriage return \r character. So AT+RST actually ends up being AT+RST\r\n. This took me a bit when I first received my ESP8266 modules. On the Arduino serial console this option is at the bottom of the window. I can see in your video you have it set to no line ending. Hopefully that does it for you.
