Introduction

This page is about a LoRa gateway at RevSpace configured for The-Things-Network (TTN), kindly provided by Dave_O.

With this piece of hardware we are able to receive LoRa packets and forward them to The Things Network. Why do we "team up" with The Things Network? [1].

The Things Network act as hub and collects all these packets from hundreds of receivers world-wide. Read more about their network on their wiki.

Hardware

It's a Kerlink, some essential properties:

  • LoRaWAN EUI: 0000024B080606AC
  • eth0 MAC address: 02:4B:08:06:06:AC
  • Last known IPv4 in the RevSpace LAN: 10.42.45.15

The gateway itself is physically mounted in the ceiling of a disused lavatory on the second floor (with a broken light and a sign that says "Beware of the Leopard", just kidding). It's connected to our discone antenna.

Configuration

Configuration files for TTN in general can be found here:

  • in /mnt/fsuser-1/thethingsnetwork

The gateway is configured for NTP in /etc/ntp.conf to use X.nl.pool.ntp.org where X goes from 0 to 3.

The gateway has been configured for "poly"-packet forwarding. This means it's not just sending data to TTN, but also to the gatewaystats.org website where statistics are kept (number of unique nodes, log of all received packets, etc.)

Status and diagnostics

Online status:

To see what the gateway is communicating with the TTN, run the following on the gateway:

tcpdump -i eth0 -n -vvvX host router.eu.thethings.network

This should show a packet once every 30 seconds with some stats.

You'll also see some JSON packets for each packet received.
