Hello. I have a problem with my project. I have two types of codes. My smartphone can't recognise ESP8266 when I upload the first code. But in the second case, my smartphone knows easily ESP8266. can anyone guide me that what is the problem of first code?
this is the first code:
/* include library */
#include <ESP8266WiFi.h>
#include <ESP8266WebServer.h>
WiFiClient client;
/* defining server prt */
ESP8266WebServer server(80);
/* Define WiFi Credentials */
const char* ssid = "hash";/* Your SSID */
const char* password = "12345678";/* Your Password*/
String data="";
int robotspeed = 1023;
/* Defining right and left motor pins */
int RMotor_1 = 0;
int RMotor_2 = 2;
int LMotor_1 = 13;
int LMotor_2 = 15;
/* Defining L298N enable pins */
int REnable = 14;
int LEnable = 12;
void setup() {
Serial.begin(115200);
Serial.println("GPIO test!");
/* Initialize Motor Control Pins as Output */
pinMode(RMotor_1, OUTPUT);
pinMode(RMotor_2, OUTPUT);
pinMode(LMotor_1, OUTPUT);
pinMode(LMotor_2, OUTPUT);
/* Initialize Motor Enable Pins as Output */
pinMode(REnable, OUTPUT);
pinMode(LEnable, OUTPUT);
/*connecting to WiFi */
server.begin();
Serial.println("server started");
}
/* Move Forward */
void move_forward() {
digitalWrite(RMotor_1,LOW);
digitalWrite(RMotor_2,HIGH);
digitalWrite(LMotor_1,HIGH);
digitalWrite(LMotor_2,LOW);
}
/* Move Backward */
void move_backward() {
digitalWrite(RMotor_1,HIGH);
digitalWrite(RMotor_2,LOW);
digitalWrite(LMotor_1,LOW);
digitalWrite(LMotor_2,HIGH);
}
/* Move Right */
void turn_right() {
digitalWrite(RMotor_1,LOW);
digitalWrite(RMotor_2,HIGH);
digitalWrite(LMotor_1,LOW);
digitalWrite(LMotor_2,HIGH);
}
/* Move Left */
void turn_left() {
digitalWrite(RMotor_1,HIGH);
digitalWrite(RMotor_2,LOW);
digitalWrite(LMotor_1,HIGH);
digitalWrite(LMotor_2,LOW);
}
/* Stop Move */
void move_stop() {
digitalWrite(RMotor_1,LOW);
digitalWrite(RMotor_2,LOW);
digitalWrite(LMotor_1,LOW);
digitalWrite(LMotor_2,LOW);
}
void loop() {
analogWrite(REnable, robotspeed);
analogWrite(LEnable, robotspeed);
/* Handling Request */
server.handleClient();
String data = server.arg("Key");
Serial.println(data);
/* Setting Speed */
if (server.hasArg("Speed")) {
int _speed = (server.arg("Speed").toInt());
robotspeed = _speed;
Serial.println(robotspeed);
}
if (data == "F") {
move_forward(); /* If data B moves forward */
}
else if (data == "B") {
move_backward(); /* If data B moves Backward */
}
else if (data == "R") {
turn_right(); /* If data B moves Right */
}
else if (data == "L") {
turn_left(); /* If data B moves Left */
}
else if (data == "S") {
move_stop(); /* If data B moves Bstop moving */
}
}
void handleRequest() {
if (server.hasArg("Key")) {
Serial.println(server.arg("Key"));
}
if (server.hasArg("Speed")) {
Serial.println(server.arg("Speed"));
}
server.send(200,"text/html","");
delay(1);
}
void connectingToWiFi() {
delay(3000);
WiFi.disconnect();
delay(1000);
Serial.println("Connecting to WiFi");
WiFi.begin(ssid, password);
while ((!(WiFi.status() == WL_CONNECTED))) {
delay(1000);
Serial.print("...");
}
Serial.println("Connected");
Serial.println("Local IP is : ");
Serial.print((WiFi.localIP().toString()));
delay(5000);
}
and this is the second code:
