蓝色 ESP8266-12e tx 灯常亮

Question

我有一些代码放在 ESP8266-12e 板上。直到最近它总是工作正常。现在，当我完成上传代码时，ESP8266-12e 上的蓝灯一直亮着。我在两块不同的板上试过，两块板上的蓝灯都亮着。我无法弄清楚我在代码中更改了什么。我决定把它贴出来让大家看看，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：

希望不要太长。

无论如何我希望有人能找到我的问题。一切正常，蓝灯亮着就是我能看出来的。

当我上传另一个代码时，它不会停留，所以它必须在代码中。我会继续寻找。

谢谢

所以我让蓝灯熄灭了。而不是 pinMode(D4,INPUT);和数字写入（D4，低）； D4 是引脚 16，它是唤醒引脚。所以我必须这样定义它 #define LED3 16 然后是 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。
