ESP 8266 程序问题
ESP 8266 Program Issue
描述
我正在 ESP-8266(01) 上编写一个网络服务器,它将使用 Arduino Mega 控制 3 个锁。
锁将由蓝牙 ESP 8266(从 phone 获取方法)和使用我的笔记本电脑浏览器控制。
我可以使用蓝牙 HC-05(轻松)完成这一切。
我遇到的问题是我的 ESP-8266 wifi 模块。
我需要从 ESP 发送 3 个不同的字符串供 Arduino 读取。
如果是“AAAA”,Arduino 会读取它并解锁一号门,如果是 BBBB,则打开二号门,等等……
所以我使用了这段代码:
#include <ESP8266WiFi.h>
const char* ssid = "Do-Not-Ask-For-Password";
const char* password = "ITISMYPASSWORD";
//const char* ssid = "`STAR-NET-Azhar-32210352";
//const char* password = "ITISMYPASSWORD";
int ledPin = 2; // GPIO2
WiFiServer server(80);
// Update these with values suitable for your network.
IPAddress ip(192,168,8,128); //Node static IP
IPAddress gateway(192,168,8,1);
IPAddress subnet(255,255,255,0);
void setup() {
Serial.begin(115200);
delay(10);
pinMode(ledPin, OUTPUT);
digitalWrite(ledPin, LOW);
// Connect to WiFi network
Serial.println();
Serial.println();
Serial.print("connecting to ");
Serial.println(ssid);
WiFi.begin(ssid, password);
WiFi.config(ip, gateway, subnet);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("");
Serial.println("WiFi connected");
// Start the server
server.begin();
Serial.println("Server started");
// Print the IP address
Serial.print("Use this URL to connect: ");
Serial.print("http://");
Serial.print(WiFi.localIP());
Serial.println("/");
}
void loop() {
ESP.wdtDisable();
// Check if a client has connected
WiFiClient client = server.available();
if (!client) {
return;
}
// Wait until the client sends some data
// Serial.println("new client");
// while(!client.available()){
// delay(1);
// }
if(!client.available()){
delay(1);
client.flush();
}
// Read the first line of the request
String request = client.readStringUntil('\r');
//Serial.println(request);
client.flush();
// Match the request
int value1 = LOW;
int value2 = LOW;
int value3 = LOW;
if (request.indexOf("/LOCK=ON1") != -1) {
//digitalWrite(ledPin, HIGH);
value1 = HIGH;
Serial.println("AAAA");
}
if(request.indexOf("/LOCK=ON2") != -1){
value2 = HIGH;
Serial.println("BBBB");
}
if(request.indexOf("/LOCK=ON3") != -1){
value3 = HIGH;
Serial.println("CCCC");
}
// Set ledPin according to the request
//digitalWrite(ledPin, value);
// Return the response
client.println("HTTP/1.1 200 OK");
client.println("Content-Type: text/html");
client.println(""); // do not forget this one
client.println("<!DOCTYPE HTML>");
client.println("<html>");
client.println("<br><br>");
client.print("LOCK ONE IS NOW: ");
if(value1 == HIGH) {
client.print("UNLOCKED");
// Serial.println("A");
} else {
client.print("LOCKED");
}
client.println("<br><br>");
client.print("LOCK TWO IS NOW: ");
if(value2 == HIGH) {
client.print("UNLOCKED");
// Serial.println("B");
} else {
client.print("LOCKED");
}
client.println("<br><br>");
client.print("LOCK THREE IS NOW: ");
if(value3 == HIGH) {
client.print("UNLOCKED");
//Serial.println("C");
} else {
client.print("LOCKED");
}
client.println("<br><br>");
client.println("CLICK <a href=\"/LOCK=ON1\">HERE</a> TO UNLOCK THE LOCK ONE<br>");
client.println("CLICK <a href=\"/LOCK=ON2\">HERE</a> TO UNLOCK THE LOCK TWO<br>");
client.println("CLICK <a href=\"/LOCK=ON3\">HERE</a> TO UNLOCK THE LOCK THREE<br>");
client.println("</html>");
delay(100);
//Serial.println("client disconnected");
// Serial.println("");
}
我在浏览器上得到的结果是(这是我需要的):

问题:
现在的问题是有时它会错过我发送的串行数据,例如,如果我点击解锁门 1,它会发送数据,然后我点击解锁门 2,它不会发送数据,当我重置时,它会从所有 3 个门发送数据但是2到3次然后模块自行重置....
这是我从串口监视器得到的:
enter image description here
现在我已经搜索了很多,它监视着我在代码中做错了什么。
这是我的 ESP 的连接方式:
vcc 和 CHPD 到 3.3V 稳压器
gnd 到 powersuply 的 gnd 和 arduino gnd...
GP 0 ------> 3.3v 带 2.2k 电阻(非闪烁状态)。
Rst ------> 3.3v 带电阻
接收到发送
TX 到 RX
有什么解决办法吗?
有没有其他方法可以从 ESP 8266 模块控制 Arduino 引脚(6 个不同的引脚)?
我已经尝试了很多天了,请帮忙!!
好的,我发布给那些面临同样问题的人!!我拿了 Hello ESP 示例并将其修改为 Print Serial!!!
在 Mega 上,我的序列号开始于 9600,我在 ESP 上的序列号也开始于 9600:|这就是代码....慢速服务器和 WDT 问题几乎消失了....

const char* ssid = "Do-Not-Ask-For-Password";
const char* password = "AeDrkiILA!$#2";
