Bottom line here is that PyCom sells less than user friendly devices and provides poor documentation on use. I have been trying repeatedly to get my LoPy4 to OTAA join to no avail. I have scoured and tried just about every code sample on GitHub and nothing. Sadly, I did get my 32u4 feather to join with no issues whatsoever. This pisses me off because I dropped nearly $80 on PyCom (board, LoPy4, antenna, shipping) The forum is hardly readable. As are the docs. Just plain lousy.

@paul-thornton said in LoRa (Raw) & MQTT vs. LoRaWAN & private LoRaWAN server: Is this something that has to be completely self hosted? From the current state of things, yes, it has to. I need a solution that can scale up. We think about several hundrets of nodes with several gateways per application. Everything has to be self powered. And also for now, it's not clear if the gateways will have a permanent connection to the higher-level network, or will initially store all the information and load them up in fixed intervals. My first attempt was, to use TTN. But there are opinions that speak against it. Think of areas in the world where the Internet is not as free as it should be. Cheers, Thomas

I'm trying to use nano-gateway with loraserver.io but I can not downstream messages just upstream. Can you share if you had the same problem?
