Default Hivemq QOS value is 1?

Default Hivemq QOS value is 1?

Hello @Susan

While HiveMQ does support all MQTT QoS levels, it’s not accurate to say that the “default” QoS is 1. The default QoS for publishing messages is 0 unless specified otherwise by the client. The QoS for receiving messages depends on what the client specifies when it subscribes to a topic.

I’d highly recommend revisiting our “MQTT Essentials” series as suggested previously.

Kind regards,
Diego from HiveMQ Team
