Add a LoRaWAN End Device
This section shows how to add a LoRaWAN End device to a LoRaWAN network and see the data
from TTN web site.
We use LT-33222-L IO Controller as a reference device - the setup for other LoRaWAN devices
will be similar.
Step 1
​
: Create a Device definition in TTN with the OTAA keys from the example LT-33222-L IO
Controller device.
Three codes are required to define the device in TTN:
DEV EUI - Unique ID code for a particular device.
APP EUI - ID code for an Application defined in TTN.
APP Key - Unique key to secure communications with a particular device.
A set of these codes are stored in each device by the manufacturer as the default codes for that
particular device. Each device is shipped with a sticker with the default Device EUI as shown
below.
Note: You may be able to change these codes in a device by using a configuration facility on the
device e.g. the LT33222 uses a serial port access and a series of AT commands. Changing the
codes may be necessary in the case where you have to use codes assigned by a LoRa WAN
server.
For the TTN server, you can use the codes set in the device as in the following example.
Select
​
Add Application
​
to open the screen below.
Note that there is an APP EUI already created by TTN, but this is not the one set in the device. To
add the APP EUI for the LT33222 device, select
​
Manage
​ ​
EUIs
​
and
​
Add
​ ​
EUI
​
, then enter the
required code.
