How to connect EMQX and MQTT brokers to Cloud Studio IoT
EMQX moves MQTT messages between devices; Cloud Studio IoT is what reads them, stores them and acts on them. Every instance of the platform has its own MQTT server, with TLS on port 8883 and its own credentials, so devices can publish to it directly or EMQX can bridge the topics towards it. Nothing in your broker has to change.
How to connect it
- 1
Create the MQTT credentials
In Gear Manager, under Security > MQTT Configuration, create the user and password. That user id is also the prefix of every topic.
- 2
Point the traffic at the instance
Connect the devices, or an EMQX bridge, to your instance's MQTT server over TLS on port 8883.
- 3
Publish on the uplink topic
Each device publishes to {MQTTUserID}/uplink/{DeviceAddress}. Commands travel back to the device over its downlink topic.
- 4
Decode the payload
Natively supported models are decoded out of the box. For your own payloads, a JavaScript script turns the message into the variables you want to keep.
What you get
- Storage, dashboards and alarms for the messages your broker already carries
- Two-way traffic: uplink from the device, downlink commands from the platform
- The same instance also takes LoRaWAN, HTTP and TCP devices
