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
