Class BowireMqttProtocol

Namespace

Kuestenlogik.Bowire.Protocol.Mqtt

Assembly

Kuestenlogik.Bowire.Protocol.Mqtt.dll

Bowire protocol plugin for MQTT 3.1.1 / 5.0 brokers via MQTTnet.

Discovery model:

• Connects to the broker and subscribes to # (all topics) for a short window, collecting active topic prefixes.
• Each top-level topic prefix becomes a BowireServiceInfo.
• Individual sub-topics become methods: Publish (Unary) and Subscribe (ServerStreaming).

Payload handling:

• Payloads are tried as JSON first, then UTF-8 text, then hex-dumped. This makes the plugin usable for both structured IoT data (JSON) and raw binary payloads.
