`Arduino_ESP_OTA`
====================

*Note: This library is currently in [beta](#board-support).*

This library allows OTA (Over-The-Air) firmware updates for ESP boards. OTA binaries are downloaded via WiFi and stored in the OTA flash partition. After a reset the ESP bootloader performs the firmware update.
This library allows OTA (Over-The-Air) firmware updates for ESP32 boards. OTA binaries are downloaded via WiFi and stored in the OTA flash partition. After a reset the ESP32 bootloader update the reference to the new firmware.

## Requirements

* Flash size > 2MB
* OTA_1 partition available within selected partition scheme
