Hola comunidad, les traigo una duda que ya llevo como 4 hs tratando de resolver, tengo un código para poder apagar y encender la luz desde el celular mi problema en si es el Modulo ya que no me da respuesta alguna ningún OK o ready, ninguna respuesta, y la luz azul de Comm no se prende, no tengo idea cual puede ser el problema hay códigos que si "funcionan" pero que solo me tiran un Listo (Como si ya pudiera ser utilizado y nada) y no me responden con ningún comando AT y hay otros que definitivamente no me funcionan.

Les dejo el código :

#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()
{
SSSerial.begin(19200);
esp8266.begin(19200); // your esp's baud rate might be different

pinMode(10,OUTPUT);
digitalWrite(10,LOW);

pinMode(11,OUTPUT);
digitalWrite(11,LOW);

pinMode(12,OUTPUT);
digitalWrite(12,LOW);

pinMode(13,OUTPUT);
digitalWrite(13,LOW);

sendData("AT+RST\r\n",2000,DEBUG); // reset module
sendData("AT+CWMODE=2\r\n",1000,DEBUG); // configure as access point
sendData("AT+CIFSR\r\n",1000,DEBUG); // get ip address
sendData("AT+CIPMUX=1\r\n",1000,DEBUG); // configure for multiple connections
sendData("AT+CIPSERVER=1,80\r\n",1000,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(1000); // wait for the serial buffer to fill up (read all the serial data)
// get the connection id so that we can then disconnect
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

esp8266.find("pin="); // advance cursor to "pin="

int pinNumber = (esp8266.read()-48)*10; // get first number i.e. if the pin 13 then the 1st number is 1, then multiply to get 10
pinNumber += (esp8266.read()-48); // get second number, i.e. if the pin number is 13 then the 2nd number is 3, then add to the first number

digitalWrite(pinNumber, !digitalRead(pinNumber)); // toggle pin

// make close command
String closeCommand = "AT+CIPCLOSE=";
closeCommand+=connectionId; // append connection id
closeCommand+="\r\n";

sendData(closeCommand,1000,DEBUG); // close connection
}
}
}

  • Name: sendData

  • Returns: The response from the esp8266 (if there is a reponse)
