ESP8266 Community Forum

- Sun Oct 30, 2016 7:11 pm #57412 hello ... will see'm new to the forum, and I want to know if anyone could help me with a little problem ... a couple of days esp8266 firmware update to use your library in the IDE arduino, after updating the internal baudrate I stayed in 115200 by default. now I wanted to make a small project with arduino one and the esp8266 ... now the problem is that after the esp8266 charge you a program from the IDE arduino no longer wanted to run AT commands esp8266 and now do not know how to change the internal baudrate ... someone who can help me with this problem please

- Sun Oct 30, 2016 9:24 pm #57415 I think you are saying you got an esp8266 (Had Espressif AT firmware on it) and flashed arduino code on it using the Arduino IDE. Arduino code won't respond to AT commands so you want to flash it back. You should be able to flash it back to AT firmware. Check this link out.

- Mon Oct 31, 2016 10:58 am #57442 Thanks for the help swilson ... I did what you told me, and I returned to load the firmware, and could change the baudrate of esp8266 to 57600...pero now I emerged a new problem, as he had already said, I am in a small project consisting to send data from arduino (one) to a local database (mysql-xampp) through esp8266 ... at first i was just sending data from the keyboard to esp8266 and this sent him to the database (had no problem with that) ... what happens now is that I can not communicate with the arduino esp8266 through SoftwareSerial library, I think there is a problem with my code or am I ignoring some way ... I attached the code arduino and esp8266 (for the module I'm using your library)

Code: Select all//This one code to arduino
#include <SoftwareSerial.h>
SoftwareSerial esp8266(2,3);
char mensaje;
int cont=0;
void setup(){ 
  pinMode(8,INPUT);
  Serial.begin(9600);
  esp8266.begin(9600);   
}
void loop()
{
  while(Serial.available()>0)
  {
    mensaje=Serial.read();
  }
     
      if(mensaje=='1')
        {
            if(digitalRead(8)==HIGH)
            {
              cont++;                           
              Serial.println(cont);
              delay(250);             
            }
        }
        else{
          if(mensaje=='0')
          {
              esp8266.println(cont);
              cont=0;
              mensaje='1';   
          }         
        }
}

this one code to ESP8266

Code: Select all#include <ESP8266WiFi.h>

const char* ssid     = "SSID";
const char* password = "PASSWORD";

const char* host = "10.0.0.10";//ip local of my pc
int date=0;
void setup() {
  Serial.begin(9600);//
  delay(10);

  // We start by connecting to a WiFi network

  Serial.println();
  Serial.println();
  Serial.print("Connecting to ");
  Serial.println(ssid);
 
  WiFi.begin(ssid, password);
 
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }

  Serial.println("");
  Serial.println("WiFi connected"); 
  Serial.println("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  delay(5000);
  WiFiClient client;
  const int httpPort = 80;
  if (!client.connect(host, httpPort)) {
    Serial.println("connection failed");
    return;
  }
  while(Serial.available()>0)
  {
    dato=Serial.read();
  //Serial.println(date);
  // This will send the request to the server
    client.print("GET /Project/save.php?value=");
    client.print(date);
    client.println("HTTP/1.1");
  }

}

any help is welcome

- Thu Nov 03, 2016 7:59 pm #57631 So try one way or another, I could solve my problem ... the solution was to change TX and RX pins ... pins 2 and 3 he was using were faulty, so I switch to pins 10 and 11
