Question

我在esp8266 201上遇到了一些问题。我用一个（绰绰有余的）电源供电，它不断重启。

即使esp8266有时连接到互联网并且Cayenne发现它，它也会脱机并再次联机。有些人告诉我使用产量，但我不知道如何使用它们。

以下代码用于连接Cayenne并为其添加一些传感器。这发生在收益之前。

 #include <SoftwareSerial.h>   //SoftwareSerial library required for Arduino  communication with the Grove RFID reader and the Grove Serial MP3 player
 #include <BlynkSimpleEsp8266.h>

 char token[] = "";        //Cayenne authentication token. This should be obtained from the Cayenne Dashboard.
 // Your network name and password.
 char ssid[] = "";
 char password[] = "";             

 SoftwareSerial mp3(2,3);                                  //Grove Serial MP3 Player is connected to Digital Pins 2 and 3
 SoftwareSerial rfid(10,11);                               //Grove 125kHz  RFID reader is connected to Digital Pins 10 and 11 (Note: lower pins may not work with this board)

Answer 1

评论中尚未提及需要至少0.1uF的去耦/支持电容。

我最终使用micro python及其webrepl进行重置。在ESP Vcc和Gnd Pin上直接添加一个10uF陶瓷电容后，一切都运行良好。

请记住，ESP不仅消耗芯片本身的180mA峰值电流。闪光灯在峰值时也会消耗大电流。

此处还讨论了：http://internetofhomethings.com/homethings/?p=396

编辑：这是我的ESP-12F的照片。我所有的ESP都连接了这些电容器，即使是ESP-01

也是如此
