- Mon Feb 27, 2017 7:51 pm #63111 Hey guys,

I hope you can help me. I'm trying to make a web-controlled TV remote. For this I want to connect an IR LED to an Arduino Nano and connect it to an ESP-12 for the wifi access.

Both of the boards are supposed to communicate via software serial, thats the code I have set up for this

The modified "HelloServer"-Example code for the ESP:

Code: Select all#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>
#include <ESP8266mDNS.h>
#include <SoftwareSerial.h>
#include <WiFiManager.h>

ESP8266WebServer server(80);
SoftwareSerial arduino(14, 12); // RX, TX

void handleRoot() {
  server.send(200, "text/plain", "hello from esp8266!");
}

void handleNotFound(){
  server.send(200, "text/plain", "not found"); 
}

void handleData(){
  String message = "";
 
  if(server.hasArg("code")){
    message += server.arg("code");
    arduino.println(message); 
  } else {
    message += "No valid parameter given";
  }

  server.send(200, "text/plain", message);
}

void setup(void){
  Serial.begin(4800);

  WiFiManager wifiManager;
  wifiManager.autoConnect("AutoConnectAP");
  Serial.println("");

  // Wait for connection
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  Serial.println("");
  Serial.print("Connected to ");
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());

  if (MDNS.begin("esp8266.local")) {
    Serial.println("MDNS responder started");
  }

  server.on("/", handleRoot);

  server.on("/data", handleData);

  server.onNotFound(handleNotFound);

  server.begin();
  Serial.println("HTTP server started");
}

void loop(void){
  server.handleClient();
}


and this one for the Arduino Nano:

Code: Select all#include <SoftwareSerial.h>
#include <IRremote.h>

SoftwareSerial esp(4, 5); // RX, TX
IRsend irsend;

void setup() {
  // Open serial communications and wait for port to open:
  Serial.begin(4800);
  while (!Serial) {
    ; // wait for serial port to connect. Needed for native USB port only
  }

  // set the data rate for the SoftwareSerial port
  esp.begin(4800);
  Serial.println("Let's go");
}

void loop() { // run over and over
  if (esp.available()) {
    Serial.println(esp.read());
  }
}


The problem is that on the serial monitor I only receive weird readings like this:

Code: Select allLet's go

Does someone know what my mistake is?

I hope you can help me!
