SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

ESP32 development often requires a local MQTT broker for testing. This Skill provides a ready-to-use broker on the Universal ESP32 Workbench to simplify device testing.

Core Features & Use Cases

  • Start, stop, and check status of a mosquitto broker deployed on the workbench.
  • Enable ESP32 devices to publish and subscribe over the workbench's WiFi AP for isolated testing.
  • Use in CI-like scenarios to validate MQTT-based firmware flows and provisioning.

Quick Start

Start the broker using the API and connect ESP32 devices to the workbench WiFi to begin MQTT testing.

FAQPage Schema
How do I test ESP32 MQTT clients with a local broker?▼

To test ESP32 MQTT clients, you can start a local mosquitto broker on the Universal ESP32 Workbench via HTTP endpoints, allowing devices to publish and subscribe over the workbench WiFi AP for isolated development and QA.

How do I start and stop the mosquitto broker on the ESP32 workbench?▼

You start and stop the mosquitto broker by sending HTTP POST requests to the /api/mqtt/start and /api/mqtt/stop endpoints, with GET /api/mqtt/status available to check the current broker state.

Do I need mosquitto installed locally to use MQTT testing on the ESP32 workbench?▼

Yes, this Skill requires mosquitto to be installed on the workbench to provide the ready-to-use MQTT broker environment for testing ESP32 MQTT clients.

What IP address should ESP32 devices use to connect to the MQTT broker on the workbench?▼

ESP32 devices should connect to the MQTT broker at the IP address 192.168.4.1 on port 1883 when they are connected to the workbench WiFi AP.

Can I use the ESP32 workbench MQTT broker for CI-like firmware validation?▼

Yes, you can use this MQTT broker setup in CI-like scenarios to validate MQTT-based firmware flows and provisioning by simulating a testing environment over the WiFi AP.
