142
143 (((
144 The LDDS45 is configured as LoRaWAN OTAA Class A mode by default. It has OTAA keys to join LoRaWAN network. To connect a LoRaWAN network, you need to input the OTAA keys in the LoRaWAN IoT server and power on the LDDS45. If there is coverage of the LoRaWAN network, it will automatically join the network via OTAA and start to send the sensor value
145 )))
146
147 (((
148 In case you can't set the OTAA keys in the LoRaWAN OTAA server, and you have to use the keys from the server, you can [[use AT Commands >>||anchor="H4.A0ConfigureLDDS45viaATCommandorLoRaWANDownlink"]]to set the keys in the LDDS45.
