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. This example is valid only for ESP8266. In order to apply this |
||||||
|
example to ESP32, it is necessary to quote WebUpdate.ino included |
||||||
|
in the ESP32 arduino core distribution and implement a class |
||||||
|
equivalent to ESP8266HTTPUpdateServer. But it is not included in this |
||||||
|
example. |
||||||
|
|
||||||
|
2. 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). |
||||||
|
|
||||||
|
3. 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. |
||||||
|
