I am working on sending messages from an MQTT broker to a Gateway.

Currently, I am using the RAK7289cv2 Gateway and the RAK11270 LoRa device. I have successfully tested sending data from the LoRa end device to the MQTT broker via the gateway. Additionally, I can send data to the end device through the gateway’s web interface.

I now need to implement data transmission from the MQTT broker to the gateway, and subsequently from the gateway to the end device. Could you provide guidance on how to achieve this?

Mayeb this helps: Use the MQTT Broker Like a Pro + Examples

I am using NodeRED to send messages through the MQTT broker to the nodes. It is different to above guide, but the steps and the MQTT packet format is the same.
