wolfSSL provides many different products for many different implementations of internet protocols, one of which is wolfMQTT. The wolfMQTT library is a client implementation of MQTT written in C for embedded use, with support for SSL/TLS via the wolfSSL library, and also provides support for MQTT-Sensor Network (MQTT-SN). While wolfMQTT is based on the MQTT 3.1.1 specification, wolfMQTT also provides support for the MQTT v5.0 specification – which was recently approved and standardized by OASIS. This new standard comes with some changes, which are outlined below (from the MQTT v5.0 standard):
- Enhancements for scalability and large scale systems
- Improved error reporting
- Formalize common patterns including capability discovery and request response
- Extensibility mechanisms including user properties
- Performance improvements and support for small clients
