ESP WebOTA

Easily add web based OTA updates to your ESP32 projects.

Installation

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

Usage

Include the WebOTA library

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

Optionally initialize the WebOTA library if you want to change the defaults . This is done at the end of your setup() function:

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

	// The defaults are 8080 and "/webota"
	// if you omit init_web_ota() it will use the defaults
    init_web_ota(8888, "/update");
}

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

void loop() {
    // Other loop code here

	handle_webota();
}

Note: If you have long delay() commands in your loop() WebOTA may not be responsive. We have provided webota_delay() as a drop-in replacement, which is more WebOTA friendly.

Upload a sketch

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.

Navigate to your ESP32 in a web browser to upload your binary image. Typical URLs are: http://esp32-ota.local:8080/webota.
