# ESP WebOTA

Easily add web based [OTA](https://en.wikipedia.org/wiki/Over-the-air_programming) updates to your ESP32 projects.

## Installation

Clone this repo to your Arduino libraries directory. On Linux this is `~/Arduino/libraries/`

## Usage

Create a global variable for the Web Server:

    #include <WebOTA.h>
    WebServer OTAServer(8080);

Initialize the WebOTA library at the end of your `setup()` function:

    void setup() {
        // Other init code here (WiFi, etc)

        init_web_ota(&OTAServer);
    }

Listen for update requests at the end of your `loop()` function:

    void loop() {
        // Other loop code here

        OTAServer.handleClient();
    }

**Note:** If you have long `delay()` commands in your `loop()` WebOTA may not be responsive.

## Upload a sketch

Navigate to your ESP32 in a web browser, typical URLs are: http://esp32-ota.local:8080/webota. You will need to create a binary sketch image to upload. This is done in the Arduino IDE by going to the `Sketch` menu and selecting `Export compiled Binary`.
