An allocation-free, I/O-agnostic MQTT client written in Zig.

Warning: this is a work in progress, the API is subject to change

• MQTT 3.1.1 client packet serialization/deserialization
• Ping handling
• Subscribe and receive data
• Publish (QoS 0 only)
• Unsubscribe
• Everything else (including a more detailed list of what's missing)

You can run the example with:

zig run example.zig 

You can use mosquitto_sub to see the message that is published by the example just after the connection

mosquitto_sub -h "mqtt.eclipseprojects.io" -t "zig/zanzara_out" 

You can use also mosquitto_pub to publish to the topic the example subscribes to

mosquitto_pub -h "mqtt.eclipseprojects.io" -t "zig/zanzara_in" -m "Hello, MQTT"
