Sketch1 - EMQX Client Demo

Uses EMQX as the external MQTT message service.

This sketch shows:

• Connecting to EMQX via WebSocket (ws://127.0.0.1:8083/mqtt)
• Creating 10 clients that receive messages from the same topic
• Creating 1 client that sends 100 timestamped messages

Setup EMQX with Docker

Start EMQX using Docker (note: old port 8081 has merged into port 18083 in new versions):

docker run -d --name emqx -p 1883:1883 -p 8083:8083 -p 8084:8084 -p 8883:8883 -p 18083:18083 emqx/emqx

Access the dashboard at http://localhost:18083 (default: admin/public).

Run

go run main.go
