WebUpdate.ino, Example for the AutoConnect library.
|
|
Copyright (c) 2018, Hieromon Ikasamo
|
|
https://github.com/Hieromon/AutoConnect
|
|
This example is an implementation of a lightweight update feature
|
|
that updates the ESP8266's firmware from your web browser. It embeds
|
|
ESP8266HTTPUpdateServer into the AutoConnect menu and can invoke the
|
|
firmware update UI via a Web browser.
|
|
You need a compiled sketch binary file to the actual update and can
|
|
retrieve it using Arduino-IDE menu: [Sketck] -> [Export compiled binary].
|
|
Then you will find the .bin file in your sketch folder. Select the.bin
|
|
file on the update UI page to update the firmware.
|
|
|
|
Notes:
|
|
1. To experience this example, your client OS needs to be running a
|
|
service that can respond to multicast DNS.
|
|
For Mac OSX support is built in through Bonjour already.
|
|
For Linux, install Avahi.
|
|
For Windows10, available since Windows10 1803(April 2018 Update/RS4).
|
|
|
|
2. If you receive an error as follows:
|
|
Update error: ERROR[11]: Invalid bootstrapping state, reset ESP8266 before updating.
|
|
You need reset the module before sketch running.
|
|
