WebSocket Server Implementation

Create a WebSocket server on the ESP32, allowing multiple clients to establish persistent connections for real-time, bidirectional communication.

Implement a WebSocket client on ESP32 for persistent, full-duplex communication channels with WebSocket servers, enabling real-time data exchange.

Understand TLS/SSL certificate management on ESP32, including storing root CAs, client certificates, and performing server certificate verification.

Secure your ESP32’s HTTP communications using HTTPS (HTTP over TLS/SSL). Learn certificate handling and secure connection establishment.

Learn to make HTTP requests (GET, POST, etc.) from your ESP32 using the ESP-IDF HTTP client library to interact with web servers and APIs.

Implement IP multicast and broadcast communication on ESP32 using UDP sockets to efficiently send data to multiple recipients simultaneously.

Utilize non-blocking socket modes on ESP32 to perform network reads and writes without halting task execution, improving application responsiveness.

Implement asynchronous socket operations on ESP32 using callbacks or event-driven models to handle network I/O without blocking application tasks.

Deep dive into various socket options (setsockopt/getsockopt) available in LwIP on ESP32 for fine-tuning TCP, UDP, and IP behavior.

Learn advanced raw socket programming on ESP32 to craft and receive custom IP packets, bypassing the standard TCP/UDP transport layers.
