Download Library Esp8266wifi.h

The Wi-Fi library for ESP8266 has been developed based on ESP8266 SDK, using the naming conventions and overall functionality philosophy of the Arduino WiFi library. Over time, the wealth of Wi-Fi features ported from ESP8266 SDK to esp8266 /Arduino outgrew Arduino WiFi library and it became apparent that we would need to provide separate documentation on what is new and extra.
How does it work? In the first line of the sketch, #include we are including the ESP8266WiFi library. This library provides ESP8266 specific Wi-Fi routines that we are calling to connect to the network.
Note: if connection is established, and then lost for some reason, ESP will automatically reconnect to the last used access point once it is again back on-line. This will be done automatically by Wi-Fi library, without any user intervention.
The ESP8266WiFi library provides a wide collection of C++methods (functions) and properties to configure and operate an ESP8266 module in station and / or soft access point mode. They are described in the following chapters.
The ESP8266WiFi library is broken up into several classes. In most of cases, when writing the code, the user is not concerned with this classification. We are using it to break up description of this library into more manageable pieces.
If code is not annotated, you will still see the function prototype including types of arguments, and can use provided links to jump straight to the source code to check it out on your own. Doxygen provides really excellent navigation between members of library.
If you are using the Arduino IDE installed in root/Arduino-1.8.5/, then root/Arduino-1.8.5/hardware/esp8266com/esp8266/libraries/ESP8266WiFi/src/ESP8266WiFi.h should be recognized, but it will only be found when you have one of the ESP8266 core for Arduino boards selected from the Tools > Board menu. The library is specifically written for ESP8266 so it wouldn't work for any other board anyway.
Well, I think we got it pert. I was able to compile and upload it successfully. It was a combination of upgrading to 1.8.12, getting python 3 adjusted and getting the library and sketchbook in the proper places.
Now comes the testing part.
I am trying to use the ESP8266WiFi library, but it is not found. Meanwhile I believe trough further reading that it might be included in PlatformIO. However when I try to compile my sample project I get an error:
As far as I know esp8266 base library (GitHub - esp8266/Arduino: ESP8266 core for Arduino) are automatically included on platform = espressif8266, but megaatmega2560 board are not supported on platform espressif8266. Is there any way to use esp8266 base library with megaatmega2560 board?
Continuing the discussion from The smallest Wifi smartphone controlled 4WD car using ESP8266, Blynk and Arduino Code:
Hi sir,
I am interested in the above mentioned project and I am not engineering person but love to build up projects like this.
Here I am dissapointed that when I try to compile the sketch it shows error esp8266wifi.h library not found. I tried each and every thing that was mentioned on Google but with no results.
Is there any broken link.
I am using arduino ide 1.8.9 and successfully downloaded blynk library and esp8266 by esp community board.
Can you please help me out regarding this.
My email address guptama...@gmail.com
It will be very helpful of you if you can help me.
And also install the latest Blynk library. GitHub - blynkkk/blynk-library: Blynk library for IoT boards. Works with Arduino, ESP32, ESP8266, Raspberry Pi, Particle, ARM Mbed, etc.
There are many tutorials out there on how to install library.
With the Arduino WiFi Shield, this library allows an Arduino board to connect to the internet. It can serve as either a server accepting incoming connections or a client making outgoing ones. The library supports WEP and WPA2 Personal encryption, but not WPA2 Enterprise. Also note, if the SSID is not broadcast, the shield cannot connect.
Days ago we made some improvements in the Ubidots ESP8266 library, so you should wait a few days in order to use the new version of the library and avoid any issue. If you desire, I can let you know when the library is available for the users.
The only limitation of using the examples provided in the library is that you will be not able to make debug because the arduino Nano just have one serial port, but it should work without any problem. Remember modify the code to send the data through the right serial port.
Wire library currently supports master mode up to approximately 450KHz.Before using I2C, pins for SDA and SCL need to be set by callingWire.begin(int sda, int scl), i.e. Wire.begin(0, 2) on ESP-01,else they default to pins 4(SDA) and 5(SCL).
An ESP8266 port of SoftwareSerial library done by Peter Lerup (@plerup) supports baud rate up to 115200 and multiples SoftwareSerial instances. See if you want to suggest an improvement or open an issue related to SoftwareSerial.
Library was adapted to work with ESP8266 by including register definitions into OneWire.hNote that if you already have OneWire library in your Arduino/libraries folder, it will be usedinstead of the one that comes with this package.
This library exposes the ability to control RC (hobby) servo motors. It will support upto 24 servos on any available output pin. By defualt the first 12 servos will use Timer0 and currently this will not interfere with any other support. Servo counts above 12 will use Timer1 and features that use it will be effected.While many RC servo motors will accept the 3.3V IO data pin from a ESP8266, most will not be able to run off 3.3v and will require another power source that matches their specifications. Make sure to connect the grounds between the ESP8266 and the servo motor power supply.

Important for anybody that has problems accessing webpages with the ESP8266.
Suddenly during the past few weeks when I was on a long earned holliday abroad several readers started to mail me. They seemed to have a problem with projects on my weblog. And as I could see it was not just with one project but with several projects. Then I saw that all these projects had one thing in common: the used the ESP8266HTTPClient library.
So I had to test the code myself. Several possible errors came to my mind. Myabe they used a different version of the Arduino IDE. I am using version 1.8.10 but maybe they were using the new version 2.0 or an older version. And another option was that these readers were using a different version of the ESP8266HTTPClient library. Something must be going on as multiple readers contacted me and they all had the same error.
Obsolete API
You will never be the first. Aruna Tennakoon had already done it a few months ago. But his approach did not suit me. I wanted something that could be easily embedded into an existing solution (like my ESPurna firmware). So I've coded it into a library I could include in my other projects and have it run in 3 lines of code. Literally.
Lately I have been migrating ESPurna to the state-of-the-art ESPAsyncWebServer by core developer Hristo Gochkov (@me-no-dev). So I decided to go for his suit of asynchronous TCP and UDP libraries for this project (note: finally the ESPAsyncUDP library has been removed and its using the WiFiUdp instead). The result is a fast, sturdy library that is amazingly easy to use.
As I said, the fauxmoESP library depends on ESPAsyncTCP and ESPAsyncUDP libraries by Gochkov. You will need those first in order to compile it. You will also need the latest Arduino ESP8266 Core installation, at least from after July 11 2016. This is required to join the multicast group where the WeMo app (or Alexa) broadcast a message when searching for compatible devices.
The library allows you to define more than one device to be discovered and then perform different actions depending on which one was triggered. This was a suggestion by user Dave Myers in the comments below and has meant a change in the library API. Version 2.0 includes some discovery optimizations and has some API changes. The example below is taken from the 2.0.0 examples. As you can see the library requires a minimum setup.
