# ESP8266_resources

General Resources for ESP8266

##Simple Serial repeater with Arduino

For writing AT commands to ESP8266 using an Arduino as a USB-UART adaptor.

Connect ESP8266 to Arduino using pins 10 and 11 as RX and TX respectively, 3.3v and GND. 

(A diagram for an ESP8266 breakout board will be coming soon)

Upload following code to the Arduino.

```cpp

#include 

SoftwareSerial softSerial(10, 11);

void setup() {

  

  // Open serial connection

  Serial.begin(9600);

  // set the data rate for the softSerial port

  softSerial.begin(9600);

}

void loop() {

  

  // if data is available from softSerial write it to Serial

  if (softSerial.available()) {

    Serial.write(softSerial.read());

  }

  

  // if data is available from Serial write it to softSerial

  if (Serial.available()) {

    softSerial.write(Serial.read());

  }

  

}

```

Open Arduino Serial Monitor. Tools->Serial Monitor

Set Arduino Serial Monitor to 9600 baud, line ending to "Both NL & CR".

Reset ESP8266 and you should see something like the following in the serial monitor:

```

ó£àåP%ÐÇCŒÁaæ l!È͐$#vÿFgØ¡P¥øùæ |gø

[Vendor:www.ai-thinker.com Version:0.9.2.4]

ready

```

The second test would be to try an AT command such as `AT+GMR` which should respond with

the firmware version of your ESP8266 module.

**Connecting to an access point**

```

AT+CWJAP="",""

```

**Check IP address**

```

AT+CIFSR

```
