蓝色 ESP8266-12e TX 灯一直亮着

如何解决蓝色 ESP8266-12e TX 灯一直亮着

我有一些代码放在 ESP8266-12e 板上。直到最近，它一直运行良好。现在，当我完成上传代码时，ESP8266-12e 上的蓝灯一直亮着。我已经在两个不同的板上试过了，蓝灯都亮着。我无法弄清楚我在代码中更改了什么。我决定把它放上来，让每个人都看看它，让我知道我可能遗漏了什么。我希望有人能找到一些东西。

我的代码：

}

希望不会太长。

无论如何，我希望有人能找到我的问题。一切正常，蓝色灯亮起，我知道应该是这样。

当我上传另一个代码时，它不会保留，所以它必须在代码中。我会继续寻找。

谢谢

解决方法

所以我让蓝光熄灭了。而不是 pinMode(D4,INPUT);和 digitalWrite(D4,LOW); D4 是引脚 16，它是唤醒引脚。所以我必须这样定义它 #define LED3 16 然后 pinMode(LED3,INPUT);和数字写入（LED3，低）；我将更改我的原始代码以反映这些更改。
