About:
WolfMQTT is a client implementation of the MQTT 3.1.1 and 5.0 protocol specifications. It is designed to be small, fast, and highly portable, making it suitable for constrained environments like embedded systems and IoT devices. The library provides robust support for TLS/SSL encryption and non-blocking I/O.

Key Features:

MQTT 3.1.1 and 5.0 protocol support
Small footprint and low memory usage
Support for TLS/SSL encryption
Non-blocking API for asynchronous operations
Cross-platform compatibility

Use Cases:

Embedded IoT device connectivity
Secure telemetry data transmission
Building MQTT brokers or clients in C/C++

Alternatives:

mosquitto – Mosquitto is primarily a broker but also offers a C client library; WolfMQTT is focused solely on the client implementation with a smaller footprint.
