Upgrading firmware from an HTTPS server

In the first example of the OTA update, we will start a file server in the local network and download new firmware from this server to upgrade the device. The file server is a simple Python Flask application that runs on our development machine. The device firmware will poll the firmware information from the server periodically and if it shows the firmware version on the server is different from the version that runs on the device, then it will download the new firmware from the server for an upgrade.

One of the important points in OTA updates is that we want a secure communication channel between the server and devices to prevent any unwanted ears from listening to the network traffic and intercepting the new firmware while transferring to the devices. Thus, we will configure the server with TLS encryption in this example. The Flask application will use a TLS certificate to encrypt the HTTP traffic between the parties. On the ESP32 application...
