LoRaWAN Network Server (LNS)

LNS establishes a data connection between a LoRa Basics™ Station and The Things Enterprise Stack . This page contains information about connecting your gateway to The Things Enterprise Stack using the LoRaWAN® Network Server (LNS) protocol.

The LNS protocol is required for sending and receiving LoRaWAN data with LoRa Basics™ Station, while the CUPS protocol is not.

Requirements

  1. User account on The Things Enterprise Stack with rights to create gateways.
  2. A gateway which support LoRa Basics™ Station.

Create a Gateway

To connect a gateway using the LNS protocol, you must first add the gateway in The Things Enterprise Stack . This can be done either in the console, or via the command line. See instructions for Adding Gateways.

Create an API Key

LNS requires an API Key with the following rights:

  • Link as Gateway to a Gateway Server for traffic exchange, i.e. write uplink and read downlink

To create an API key for your gateway, follow instructions for Creating a Gateway API key in Adding Gateways.

Configure Gateway

Gateway configuration menus differ depending on the manufacturer, but all LoRa Basics™ Station gateways support the following configuration options. Consult your gateway documentation for more information about configuring your specific gateway.

LNS Server Address

The server address is the network endpoint of The Things Enterprise Stack LNS. It is a combination of the protocol (wss), the server address, and the port:

Enter the following in your gateway as the LNS Server Address: wss://<server-address>:8887

The <server-address> is the address of The Things Enterprise Stack . If you followed the Getting Started guide this is the same as what you use instead of thethings.example.com, e.g wss://thethings.example.com:8887

LNS Server Certificate / LNS Trust

This is the CA certificate which secures your domain. A .pem file containing common certificates is available in the Root Certificates Reference.

Upload the .pem file in your gateway as the LNS Server Certificate / LNS Trust.

LNS Key File

This is a file which The Things Enterprise Stack uses to verify the identity of your gateway.

Use the following command to create a file called lns.key with the <gateway-api-key> you created above.

echo "Authorization: Bearer <gateway-api-key>" | perl -p -e 's/\r\n|\n|\r/\r\n/g'  > lns.key

The above command creates a file called lns.key, terminated with a Carriage Return Line Feed (0x0D0A) character. Upload this file in your gateway as the LNS key.
