Hi, I’m new to TTN.
Previously, I used a non-LoraWan gateway and send raw MQTT messages through it and then use hivemq MQTT broker to do my IOT functions.
Now I need to switch to a new LoraWan gateway and there is no such kind of “pass through” functioning. So I start to do the same thing using The Things Network.
I have just followed the instructions and created application with MQTT server.
I’ve got the MQTT server address “au1.cloud.thethings.network:1883” with those username and passwords.Then I use MQTTBox to test this broker. I publish a simple message to this server but cannot subscribe. I’m using a random topic “TTN/Trial”.
Could you please advise what is wrong? Thank you!!
Please read up on Topics in the documentation.
TTN does not run a public MQTT server for generic messaging. You can only subscribe to messages from your devices and publish for transmission to your devices.
Thanks! So my application is simply sending MQTT messages from my LoraWan node and then I have node-red to receive these messages and display in the dashboard.
So what should I do?
In the documentation it describes what topic to subscribe to.
Details of what you have done so far?
Search also a bit on the forum we/me all the volunteers have posted a lot of information on this subject.
Hi All, thanks for your help. I’ve studied one thread in the forum about MQTT with node-red. Just tried and it works with the simulated uplink message. I will try with the real node device shortly!
