  LHT65N is configured as LoRaWAN OTAA Class A mode by default. Each LHT65N is shipped with a worldwide unique set of OTAA keys. To use LHT65N in a LoRaWAN network, first, we need to put the OTAA keys in LoRaWAN Network Server and then activate LHT65N.

  If LHT65N is under the coverage of this LoRaWAN network. LHT65N can join the LoRaWAN network automatically. After successfully joining, LHT65N will start to measure environment temperature and humidity, and start to transmit sensor data to the LoRaWAN server. The default period for each uplink is 20 minutes.
