hi, in this tutorial [mqtt node red ttn and aws](https://www.hackster.io/victorffs/connecting-stm32-lora-discovery-kit-to-aws-iot-83ee15) he doesnt add the mosca broker, just take a mqtt out block (for me it acts just as a publisher) and send the data to aws(amazon web services) where he emulates a mqtt client but where is the broker? , thanks

I moved this into #general as it isn't query about writing your own node-red node

It is from the section headed " Get the **Endpoint** adress to configure Node-RED on the Step 6". Search for that string in the tutorial to find it.
