ESP8266 I can´t connect

Using Arduino Networking, Protocols, and Devices
1

Hello, I am new with the ESP8266 Wifi Module.

I connect CH_PD and VCC to 3.3V and GDN To Ground, TX and TR to Arduino TX and TR.

I set the Serial Monitor to 9600 and Both NL and CR option. But the arduino send me this meesage

"initialization failed!"

What is wrong?

Please help me.

Thanks

I see my error. I put this code and now the response is garbage. I try 9600, 57600, 115200 bauds.

#include "SoftwareSerial.h"

SoftwareSerial esp8266(6, 7); // RX, TX

void setup()
{
Serial.begin(9600); // serial port used for debugging
esp8266.begin(9600); // your ESP's baud rate might be different
}

void loop()
{
if(esp8266.available()) // check if the ESP is sending a message
{
while(esp8266.available())
{
char c = esp8266.read(); // read the next character.
Serial.write(c); // writes data to the serial monitor
}
}

if(Serial.available())
{
delay(500); // wait to let all the input command in the serial buffer

// read the input command in a string
String cmd = "";
while(Serial.available())
{
cmd += (char)Serial.read();
}

// print the command and send it to the ESP
Serial.println("---------------------");
Serial.print(">> ");
Serial.println(cmd);
Serial.println("---------------------");
esp8266.println(cmd); // send the read character to the esp8266
}
}
