Arduino Uno Esp8266
Posted: Mon Aug 26, 2019 8:14 amHello I'm using arduino uno and a Esp8266 Huzzah board. Everything is working i can do at commands using Software Serial. I'm trying to get a Web server running also a SD Card to old files on it. But for right now I'm just trying to get a simple web page up and running. I'm attaching the sketch and Serial monitor output in here. Problem I'm having is that there is no web page. It compiles with no problem and Serial monitor says no errors it does connect to my WIFI router and does have a IP address Just no web page. I'm not very good at coding I'm really stuck can someone please help me?
This is the sketch.
And this is the output of the serial monitor.

This is the sketch.
Code: Select all
#include <SoftwareSerial.h>
#define DEBUG true
SoftwareSerial esp8266(2,3); // make RX Arduino line is pin 2, make TX Arduino line is pin 3.
// This means that you need to connect the TX line from the esp to the Arduino's pin 2
// and the RX line from the esp to the Arduino's pin 3
void setup()
{
Serial.begin(9600);
esp8266.begin(9600); // your esp's baud rate might be different
sendData("AT+RST\r\n",2000,DEBUG); // reset module
// sendData("AT",2000,DEBUG); // send AT command
// sendData("AT+GMR\r\n",2000,DEBUG); // returns firmware
// Serial.println("checking mode");
// sendData("AT+CWMODE=?\r\n",5000,DEBUG); // check supported modes
//
// Serial.println("scanning APs");
// sendData("AT+CWLAP\r\n",21000,DEBUG); // scan list of access points
Serial.println("set mode 1");
sendData("AT+CWMODE=1\r\n",5000,DEBUG); // configure as both mode
// Serial.println("joining AP");
sendData("AT+CWJAP=\"myssid\",\"982912701284\"\r\n", 16000, DEBUG); // connect to wifi
Serial.println("Testing CIFSR");
sendData("AT+CIFSR\r\n",7000,DEBUG); // get ip address
Serial.println("setting for multiple connection");
sendData("AT+CIPMUX=1",2000,DEBUG); // configure for multiple connections
Serial.println("print MAC address");
sendData("AT+CIPSTAMAC?\r\n",2000,DEBUG); // print current MAC address
Serial.println("set port 80 for server");
sendData("AT+CIPSERVER=1\r\n,80",2000,DEBUG); // turn on server on port 80
}
void loop()
{
if(esp8266.available()) // check if the esp is sending a message
{
if(esp8266.find("+IPD,"))
{
delay(2000);
int connectionId = esp8266.read()-48; // subtract 48 because the read() function returns
// the ASCII decimal value and 0 (the first decimal number) starts at 48
String webpage = "<h1>Tyagi IoT</h1><button>LED1</button>";
String cipSend = "AT+CIPSEND=";
cipSend += connectionId;
cipSend += ",";
cipSend +=webpage.length();
cipSend +="\r\n";
sendData(cipSend,1000,DEBUG);
sendData(webpage,1000,DEBUG);
webpage="<button>LED2</button>";
cipSend = "AT+CIPSEND=";
cipSend += connectionId;
cipSend += ",";
cipSend +=webpage.length();
cipSend +="\r\n";
sendData(cipSend,1000,DEBUG);
sendData(webpage,1000,DEBUG);
String closeCommand = "AT+CIPCLOSE=";
closeCommand+=connectionId; // append connection id
closeCommand+="\r\n";
sendData(closeCommand,3000,DEBUG);
}
}
}
void sendData(String command, const int timeout, boolean debug)
{
esp8266.print(command); // send the read character to the esp8266
long int time = millis();
while( (time+timeout) > millis())
{
while(esp8266.available())
{
// The esp has data so display its output to the serial window
Serial.write(esp8266.read());
}
}
}
And this is the output of the serial monitor.
