Create listener for packet-forwarder UDP protocol

zafer · October 17, 2017, 6:26am

Hi,

We have a kerlink gateway and some sensors(868MHz). We would like to create our own lora UDP listener. I have researched Lorawan specification documents and some links. e.g.:
https://docs.loraserver.io/lora-gateway-bridge/overview/

github.com

Lora-net/packet_forwarder/blob/master/PROTOCOL.TXT

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

But i could not find that how to do it. Could you please share any section of article or links which can help me to create UDP listener?

P.S. Firstly, i’d like to understand the big picture. What criteria/information/process do i need to do. So i look forward your help.

Thank you,
Zafer

Please take a look at the https://github.com/brocaar/lora-gateway-bridge source-code This piece of software is exactly doing that, setting up an UDP listener and handling the gateway communication as mentioned in your PROTOCOL.TXT link.
