Semtech UDP protocol

LaDaU · March 18, 2019, 11:31am

Hi,

I’m currently observing the traffic from my Multitech Gateway to The Things Networkserver.

The UDP-uplink message is described in Gateway connection to TTN https://www.thethingsnetwork.org/docs/gateways/start/connection.html in the example.

I can’t find the description of the fields of the UDP message.

Especially I’m interested in the stat field.

Do anybody know the different stats it can show and when it does show them?

Thanks in advance.

Basic communication protocol between Lora gateway and server
=============================================================


1. Introduction
----------------

The protocol between the gateway and the server is purposefully very basic and 
for demonstration purpose only, or for use on private and reliable networks.

There is no authentication of the gateway or the server, and the acknowledges 
are only used for network quality assessment, not to correct UDP datagrams

Thank you so much. That’s exactly what I’m looking for.
