Relevant Information For The Registration Of Devices; Payload Decoder; Checking Further Requirements - Dräger X-node Technisches Handbuch

7.1 Relevant information for the registration of
devices
As part of the registration/provisioning of a new X-node, the device is
communicated to a LoRaWAN network server. While the process may
differ, based on the LoRa standard the following information is
generally requested:
– DevEUI
– AppEUI or JoinEUI
– AppKey
Furthermore, the frequency range used and the LoRaWAN protocol
version may also be requested.
This information is available in the X-node app. For the complete list
of information, including the safety-relevant AppKey, a registration
with Owner Rights is required (see "Access authorisation", page 55).
The Owner Key and the QR code for registration as Owner can be
found on the Owner Key card provided (see "Access authorisation",
page 55). In the app, the information described is listed under the
"LoRa connection" menu item (see "Setting up/adjusting the LoRa
connection", page 64).
7.2

Payload decoder

Encrypted data packages are sent via LoRa. These are first decoded
on the application server and passed on to a payload decoder for
further processing. The payload decoder is a script that converts the
decoded data packages into a legible format on the server, e.g.
JSON.
The payload decoder and the corresponding documentation are
provided here:
– The payload decoder is available on the Dräger X-node product
page.

Checking further requirements

The X-node cannot be operated as a standalone device when used
as a linked measurement point. It is the responsibility of the user to
ensure the availability of gateways and servers, as well as their
correct configuration.
When purchasing the gateway, make sure that it supports the relevant
frequency band. The frequencies used differ according to region. For
example, data is transmitted at 868 MHz in Europe and at 915 MHz in
the US.
Following the acquisition of the gateway, the protocol that will be used
for the gateway must first be selected:
– UDP Packet Forwarder (legacy)
– LoRa Basics™ Station (recommended)
The LoRa Basics Station is recommended on the basis that it
provides greater security and offers advanced features.
There are three steps for registration of the gateway:
– Configuration of gateway
– Communication to network server
– Exchange of keys
The first step involves configuring the gateway. The URL of the
network server is first stored on the gateway. This ensures that the
gateway will send the received data packages to the correct server.
The address of the concrete network server is specific to the user. It
may also be necessary to select the appropriate frequency band for
the region on the gateway.
The second step involves communicating the gateway to the network
server. The gateway EUI (= gateway ID) is stored here in order to
allow communication with this specific gateway.
