HTTP_Server_OTA

A simple example which demonstrates OTA update by uploading the new firmware to HTTP server on ESP32 devices

How to use

Configure the project

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

In the Example Connection Configuration menu:

• Choose the network interface in the Connect using option based on your board. Currently both Wi-Fi and Ethernet are supported.
• If the Wi-Fi interface is used, provide the Wi-Fi SSID and password of the AP you wish to connect to.
• If using the Ethernet interface, set the PHY model under Ethernet PHY Device option, e.g. IP101

Build and Flash

Run idf.py -p PORT flash monitor to build and flash the project. This command checks if the partition table contains the ota_data partition and restores it to an initial state. This allows the newly loaded app to run from the factory partition.

Upload the new firmware using cURL

Use the following command to upload the new firmware image to the device: curl -X POST <device IP>/update --data-binary @<filename>
