MQTT 5 Compatible Client Libraries
MQTT 5.0 and 3.1.1 compatible and feature-rich high-performance Java client library with different API flavours and backpressure support.
HiveMQ created the MQTT C# Client as part of our larger efforts to offer the MQTT community reliable, tested, performant, and maintained MQTT clients
From Eclipse Paho, this code builds libraries which enable applications to connect to an MQTT broker to publish messages, and to subscribe to topics and receive published messages.
Python async MQTT client implementation support. If your broker does not support MQTT 5.0, client will downgrade to 3.1 and reconnect automatically.
