# Bytebeam Basic OTA Rollback Example
This example demonnstrates how to rollback over the air firmware upgrades from Bytebeam IoT Platform.

## Hardware Required
- A development board with Espressif SoC (e.g.,ESP32-DevKitC, ESP-WROVER-KIT, etc.)
- A USB cable for Power supply and programming

## Software Required
- ESP-IDF
- Bytebeam ESP-IDF SDK

## Project Configurations

Open the project configuration menu (`idf.py menuconfig`).

In the `Example Configuration` menu:

- Set the Wi-Fi configuration.
  - Set `WiFi SSID`.
  - Set `WiFi Password`.

Optional: If you need, change the other options according to your requirements.

## Build and Flash

Run `idf.py -p PORT flash monitor` to build, flash and monitor the project.

(To exit the serial monitor, type Ctrl-].)

See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects.
