ESP8266 AT固件未表明已准备就绪 [英] ESP8266 AT firmware doesn't say it's ready

问题描述

我正在使用ESP12E模块.我上传了AT Firmware.bin v1.1.1.1，将引脚0接地连接到3.3 V，重新启动了模块.

I'm using ESP12E module. I uploaded v1.1.1.1 AT Firmware.bin, connected pin 0 from ground to 3.3 V, restarted the module.

当监视COM端口时，我看到:

When monitoring the COM port I see :

最后，id并没有说它已经准备好，因此所有AT命令都不起作用.

In the end id doesn't say that it's ready and therefore none of the AT commands work.

有什么解决办法吗?

推荐答案

在您问题的图片末尾，我们看到了一些垃圾.最上面说

At the end of the image in your question, we see some garbage. On top it says

，第一个原因:2，启动模式:(3,7)

,rst cause:2, boot mode:(3,7)

这告诉我们设备已进行外部重置，并配置为从闪存启动.因此，您的引脚连接正确.如果回到垃圾状态，这将告诉我们加载的固件以不同于74880波特率的波特率工作.垃圾可能是就绪"消息.尝试从终端(arduino IDE)更改波特率，然后重新启动模块，直到看到"ready"消息.

This tells us the device had an external reset and configured to boot from flash. Thus your pin connections are correct. If we get back to garbage this tells us the loaded FW works with a different baud rate then the 74880 baud. Possibly the garbage is the "ready" message. Try to change baud rate from the terminal (arduino IDE) and reboot the module till you see the "ready" message.
