Esp8266 shield manual IP

Need Help With My Project
1

Hi to all!I tried to connect arduino Mega with ESP8266 as shield.But i dont understend how connect to my locall server,default try to cnnect blynk.cloud.com.How can I change this setting and connect to the local server?

[code]#define BLYNK_PRINT Serial

#include <ESP8266_Lib.h>
#include <BlynkSimpleShieldEsp8266.h>
//#include <ESP8266_HardSer.h>
//#include <BlynkSimpleShieldEsp8266_HardSer.h>
// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = “***************************”;

// Your WiFi credentials.
// Set password to “” for open networks.
char ssid[] = “******”;
char pass[] = “************”;

// Hardware Serial on Mega, Leonardo, Micro…
#define EspSerial Serial

// or Software Serial on Uno, Nano…
//#include <SoftwareSerial.h>
//SoftwareSerial EspSerial(15, 14); // RX, TX

// Your ESP8266 baud rate:
#define ESP8266_BAUD 115200

ESP8266 wifi(&EspSerial);
void setup()
{
// Debug console
Serial.begin(9600);

delay(10);

// Set ESP8266 baud rate
EspSerial.begin(ESP8266_BAUD);
delay(10);

Blynk.begin(auth, wifi, ssid, pass);
}

void loop()
{
Blynk.run();
}
[/code]

Example:

char server [] = "192.168.10.120";

Blynk.begin(auth, wifi, ssid, pass, server);

Thank you very much, it works!One more question: How to assign a static IP?

Take a look at the Ethernet examples and come back if you still have problems.

Edit: sorry you are not using Ethernet, see my later post.

5

yes.And “IPAddress arduino_ip ( 10, 0, 0, 20);” not work

6

Take a look at the ESP8266_Standalone_Manual_IP example in the Arduino IDE and GitHub.

You can build completely custom connection handling, like shown in https://github.com/blynkkk/blynk-library/tree/master/examples/More/ArduinoClient
Of course it’s much easier when there’s a library for your hardware, that provides standard Arduino Client interface.

Thanks, I will read and try
