Thanks for pointing out that “port 0” is the key keyword here. That brings up this post : > [@What are these port 0 downlink messages?](https://www.thethingsnetwork.org/forum/t/what-are-these-port-0-downlink-messages/22330): > > I’m sure for the right person this is an incredibly obvious question, but I haven’t been able to easily find an answer (or maybe I don’t know the right keywords). Question: What are these port 0 downlink messages I am seeing in response to my Feather M0 LORA’s uplink messages? [image] Is this OK? I’m not attempting to do acks or anything like that, as I would like to reserve bandwidth and battery life + follow best practices for a dense LORAWAN network. Thoughts? Thanks so much! Which answers the question. --- _[View the full topic](https://www.thethingsnetwork.org/forum/t/empty-downlink-in-data-console/33078)._
