/* OTAUpdate.ino, Example for the AutoConnect library. Copyright (c) 2020, 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. 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: If you receive a following error, you need reset the module before sketch running. Update error: ERROR[11]: Invalid bootstrapping state, reset ESP8266 before updating. Refer to https://hieromon.github.io/AutoConnect/faq.html#hang-up-after-reset for details.
