MQTT / QwantiFi Configuration (device settings)

Editorial note, delete before publishing Goes under: API & Command Reference › DynaFlex Programmer's Manual › Properties(new subpage — this is the one piece of QwantiFi content that belongs inside the device Programmer's Manual, because it is device-command/configuration material)

This page documents the on-device settings that put a DynaFlex / MMS reader onto the QwantiFi MQTT broker. These are device configuration properties — part of the device command protocol — which is why they live in the Programmer's Manual rather than with the cloud-side QwantiFi material. For the end-to-end feature and the cloud side, start at the QwantiFi Overview (→ Services › QwantiFi).

Configuration groups

QwantiFi provisioning writes two related configuration groups to the device:

1. MQTT configuration — the broker connection and topic settings (below).

2. Trust configuration — the TLS trust material (certificate) the device uses to validate the broker connection when TLS is in use.

Both are delivered as secured commands. The command envelope, sequencing (WAIT), and secured-command mechanics are the standard ones described in Send Secured Command to Device (→ API & Command Reference › DynaFlex Programmer's Manual › Commands › Security › Send Secured Command to Device) and Set Property (Secured) (→ API & Command Reference › DynaFlex Programmer's Manual › Commands › Settings and Information › Set Property (Secured)).

Each row is one settable property. Values shown are examples.

When TLS is used, a Trust configuration command loads the TLS trust material (a certificate) onto the device so it can validate the broker. RMS supplies this as a secured command carrying the certificate payload. Non-TLS and TLS trust profiles are maintained separately on the RMS side (see Web RMS Service). (→ Services › QwantiFi › Web RMS Service)

The device reports its current MQTT settings when queried (the QwantiFi tooling's Get Config action, and RMS's Claims object, both reflect these properties). Reading properties from the device uses <mark style="color:red;"><strong>Get Property</strong></mark> (→ API & Command Reference › DynaFlex Programmer's Manual › Commands › Settings and Information › Get Property).
