PubSub on Application Server - any info?

Best of all,

we are running succesfully the TTNv3 stack on our university colleges and all devices and gateways are registered smoothly uptil now.

Remains one question : what about that PubSub integration one can make besides the webhooks and the publicly available MQTT server ? This link does not mention a word about the functionality.

Any help would be appreciated as we are examining this feature for the near future.

I am using the HTTP(s) Web hook…Are you getting an error with the HTTP WebHook or MQTT? Both protocols are pretty solid from my experience. Other communications i feel could be added but I personally don’t see the value add yet…like CoAP.

The thing is, I want to use our TTN v3 application server as a mqtt client rather than an exposed mqtt broker. The PubSub feature available in v3 should do this, like mosquitto_pub or mosquitto_sub does.

In fact, we want to publish our data with mqtt to mqtts:// The latter claims that our mqtt client is not conform the mqtt standards. As a result, we can not do any publishing nor subscription on their platform.

In any way, thanks for the answer and we are still trying to solve this issue.

Did they give any details about this? The MQTT client that The Things Stack uses is Paho (, one of the most widely used MQTT clients that exist.

Thanks @htdvisser,
I will forward your answer to your Dutch collegues in Rotterdam. They are working on it and even want to contact you for a connector to their architecture.
We are still following up this case.
