Which MQTT protocol version does HiveMQ CE support - v3.x or v5.x (and maybe v3.x at the same time?)

Hi there

Which MQTT protocol version does HiveMQ CE support - v3.x or v5.x (and maybe v3.x at the same time?)

If CE version does not support v5.x: Maybe the commercial version does - and the CE one not (yet)?

Thank you for your feedbacks.

Kind regards, Jan

Hi @xdev,

the Community Edition supports all MQTT versions (see https://www.hivemq.com/hivemq/editions/).

You could even enable some MQTT 5 features for MQTT 3 clients via the Extension SDK, for example enrichting MQTT 3 packets with user properties or setting session/message expiry.

Greetings,
Michael from the HiveMQ team

Hi Michael
