2.3 Example to join LoRaWAN network

This section shows an example of how to join the TTN V3 LoRaWAN IoT server. Use with other LoRaWAN IoT

servers is of a similar procedure.

Assume the LPS8N is already set to connect to

TTN V3 network

, So it provides network coverage for LHT65N.

Next we need to add the LHT65N device in TTN V3:

2.3.1 Step 1: Create Device n TTN

Create a device in TTN V3 with the OTAA keys from LHT65N.
Each LHT65N is shipped with a sticker with its device EUI, APP Key and APP EUI as below:
