The wolfMQTT client now supports connecting to v5.0 enabled brokers. Handling properties received from the server is accomplished via a customizable callback. The following v5.0 specification features are supported by the wolfMQTT client:
- AUTH packet
- User properties
- Server connect ACK properties
- Format and content type for publish
- Server disconnect
- Reason codes and strings
- Maximum packet size
- Server assigned client identifier
- Subscription ID
- Topic Alias
As a side note, wolfMQTT uses the wolfSSL embedded SSL/TLS library for SSL/TLS support. Since wolfSSL supports TLS 1.3, your wolfMQTT-based projects can now use MQTT with TLS 1.3 with a supported broker!
