Connecting ESP8266 + Arduino UNO

[Vigneshramkumar]

Hi, I am trying to connect ESP8266 and Arduino UNO. I downloaded the ESP8266 library and tried the ConnectWifi program in it. But I am not able to connect to the wifi network. It is giving me the following error. setup begin FW Version: to station err Join AP failure setup end

PFB the program I have uploaded:

include "ESP8266.h"

include "SoftwareSerial.h"

SoftwareSerial mySerial(3,2); ESP8266 wifi(mySerial);

define SSID "--------"

define PASSWORD "------------------"

//#define SERIAL_BUFFER_SIZE 256 //#define SERIAL_RX_BUFFER_SIZE 64

//ESP8266 wifi(Serial); void setup(void) { Serial.begin(9600); mySerial.begin(115200); Serial.print("setup begin\r\n");

Serial.print("FW Version: ");
Serial.println(wifi.getVersion().c_str());

if (wifi.setOprToStation()) {
    Serial.print("to station ok\r\n");
} else {
    Serial.print("to station err\r\n");
}

if (wifi.joinAP(SSID, PASSWORD)) {
    Serial.print("Join AP success\r\n");
    Serial.print("IP: ");       
    Serial.println(wifi.getLocalIP().c_str());
} else {
    Serial.print("Join AP failure\r\n");
}

Serial.print("setup end\r\n");

}

void loop(void) { } Kindly someone help me to connect the shield with the network. I already made some research with other issues section in Git hub but nothing happened. Thanks in advance.

@Vigneshramkumar, try the following modification: ESP8266 wifi(mySerial, 115200); // mySerial.begin(115200);

Move your RX, TX pins to Pin3, Pin2
